Hmmmm... just noticed I can pick up the new 1080GTX now (MSI Geforce GTX 1080 Founders Edition Graphic Card - 1733/1607 MHz - 8192MB GDDR5x - 256Bit - 3x Display Port / HDMI / DL-DVI-D - Virtual Reality Ready (GTX 1080 8G FE)) - $1031.99 Cnd. Yet the 980Ti (MSI GeForce GTX 980 Ti Gaming 6144MB GDDR5 PCI-Express Graphics Card (GTX 980Ti GAMING 6G)) is still priced at $869.99 Cdn.
Either way I'd still have to rebuild the heart of my system if I wanted to upgrade (Mobo, CPU, RAM). That alone would be about $1k without the card. I think I'll put that off for a while... *cough... choke... ack...*
You forgot to add NOT IRAY READY lol for $130 more and you have 12 GB card that works 1400Mhz clock , more cudas and low temp and use 150W in iray
Hi Cath
E5 2683 V3 is LGA 2011-3 CPU with this I'm pretty sure,as I'm running X99(LGA 2011-3) motherboard,have look
http://ark.intel.com/products/81055/Intel-Xeon-Processor-E5-2683-v3-35M-Cache-2_00-GHz
Yes i7-5960x is probably best CPU top the date if you do renders,my friend borrowed me his 5960x and 5820k for few days as I wanted to decide which one will suit me best,this E5 2683 V3 I pulled from our workstation in work as they upgraded and those CPU has been destined I think for bin..I've done only few quick renders in Corona,V-RAY and few other renderers and then I decided,E5-2683 V3 has been fastest in Corona or V-RAY
How to say,in Corona Benchrmark my CPU renders scene in 2:05(stock speeds without theb turbo),with slight OC to BCLK I can do 1:50's,i7-5960x renders same scene at 1:58 and i7-5820k will render same scene in 2:18 and 4790k will render same scene in 3:12(on mine render took 3:28 and this has been my fastest render)
Here is the Corona bechmark link
https://corona-renderer.com/benchmark/?result_page=1
Yes agree different story is in the DS as DS I still think using single core,its not multi threaded,due this you need there good CPU with higher speed,not many threads with lower speeds,same can apply for 3DS MAX,where my old I7-4790k will destroy my current setup in viewport performance,but when comes to rendering,that's different story as with i7-4790k my renders took so long and they're been slower than with my old X5670 which I overclocked to 4.2GHz
In most of CPU renderers you need to OC CPU,you will gain better performance,in some you will gain not so much and heat which they create will not result in better performance in many cases is just not worth it,I went via few of the cases and few cooling solutions and right now Phanteks Enthoo Primo SE is best case to the date what I owned(I would say is on par with my previous case Thermaltake Core X71),if you are looking for good case with good cooling which is quiet and where you can put what you want,get this case and you will be very happy Cath,its nice and roomy case
Regarding the screws,I use always screws for GPU,I think something similar happen with my friend old motherboard,when he broke PCIE slot,but this is pretty much normal on newer motherboards as they have issue/suffer with "sagging",you can get something like this,which is support bracket
http://mnpctech.com/gpu-support-bracket/
Same issue my old Asus Maximus VII Gene with i7-4790k suffered too
Regarding the memory,I can't go beyond 2400MHz on mine(limitation of the Xeon) and on yours,this will depends,I've been using Corsair RAM for many years,but still best RAM to the date what I've used has been G.Skill,with those RAM has been OC very easy,with Corsair,you can get cheaper 3200MHz RAM,but what I don't like on them are latencies,on memory you shouldn't do any compromise,if budget is allowing,if not,then all depends on more factors like where this will be used more in gaming or rendering
I don't use and never used XMP profiles,usually they putting too many volts to vCore or RAM voltage etc,usually quick dirty OC working for me,I don't like pump too many volts to CPU or RAM or MB,most of the time I spend few hours with tuning the settings to perfection if time allows,if not then I'm keeping in reasonable levels and voltages and if I see there is no BSOD in rendering,then I will lower vcore as first and CPU input voltage,CPU cache voltages etc,but mainly higher voltage usually results with higher CPU temps and this I don't like at all
This my build is test build I would say,I still have 2 months at least to return this item if I don't like or I'm not satisfied,I'm still deciding if I want to go with Z10PE-D16 or other Dual CPU workstation baord for next build or I will stick what I've,that's the question for next weeks
Cath regarding Titan X SC Hybrid,did you put own Hybrid AIO or did you bought as they're assembled ? In my case I bought Hybrid kit and put on mine this kit,as temps on stock SC has been very high when I rendered and mainly noise of fan has been too loud,but in my case this pump on Hybrid AIO makes noise
Hope this helps there and good luck
Thanks,Jura
Hi Jura , thanks for the feedback
Also thanks for the GPU brackets link, I was looking for for this and could not find in my fav stores somehow . Going to order it tonight , not taking any chances anymore .
Regarding the case I have my monster Haf 923 from Cooler Master , just replaced the side panels for $19 as they offer 3 ways for air cooling, water cooling or both hybrid as in my case, it have as much space but the radiators can be mounted on top and since I have 3 GPU radiators you can't install them bellow the GPU level as the performance will decrease , Haf 923 have 2 option so you can install stuff on top or below as it is for Water cooling systems , my CPU radiator is outside the case also and plenty of room full tower case .
Regarding the Hydro, I got 2 x Hyrid kits for the 2 Titans SC and installed myself , plus I have 1 original TitanX Hybrid , the water cooling system is the same and they are very quiet and never go beyond 20% speed keeping the GPU at 35-37 on full load and 22-25C on idle , no matter I use Precision X 16 to control it or my fan software but in most cases Precision X 16 as I keep them on the same clock and fan speed , no issues , they should be not loud at all unless you turn the speed to 100% but this never was the case , actually running the fans too fast will increase the temperature of the GPU some how so max 20% on full load . I have also double fans one side Thermaltake fans high pressure fans on the other side the original EVGA . Without the sec Thermaltake fans the temp get 3C higher and I need to run the original fans higher that maybe your situation with the noise but they should not run faster than 30% in general on full load unless the radiators are on the side or lower than the GPU .
Coming back on the processor , since I got already what I wanted I am happy with the last decision and not just because of iray only but also Zbrush , Adobe soft and other programs I use it just works fantastic for me , if is good I don't mine to pay extra as ling I am happy with the performance .
My Corsair Dominator Platinum Serie memory was not cheap actually double the price of the regular one , you can get the cheaper one that are faster but I made already this mistake before it just don't works well so I go back for what was recommended for my system .
You need always to find what works best for your rig , as we have a lot of cool stuff on the market but one good thing for ke not mean it works for you , even the same systems with exactly the same stuff inside will never perform at the same speed some how , as even folks with better processors and rig but the same cards rendered slower than my older half price rig . If my MoBo did not got screwed with the pci-e socket I would still run it right now and not upgrade anything yet as I was happy with for the last 5-6 months . I tried the other week 2 Mobo's already also with enforced with metal pci-e sockets but the MoBo''s did not perform well , I dislike the software and Bios so I am back to Asus again as it worked for me always tye best , could get my older i74790K to 5Ghz without sweat automatic with one click when I needed the speed or gow back to 1Ghz for administrative work or browsing without constantly reboot between the changes . Well on the other 2 MoBo's I could not get higher than 4.6 Ghz and constantly reboot .. no thanks
So you see we all love to drink our fav. coffee the way we love it ! don't mean it will be the best choice for you , it is personal choice as with everything else . I am very picky , if I don''t try myself I will be very skeptic. And for the last week it spent too much time trying new stuff and new brands and I wasted my time after running system for 80 hours bad things started to show up so no time for waste anymore . I have everything I need and tomorrow rebuilding everything for the last time hoping it get smooth and without issues .
Not sure if it was brought up in this thread yet -- there are a lot of pages -- but I heavily urge caution at anyone who is thinking of the 1080 at this point purely on benchmarks. In particular, specific reviewers noticed that most synthetic benchmarks were performed in open environments and not in enclosed cases. In most cases, the card was unable to sustain boost clocks inside a case and were thermally throttled. There were also issues with overclocking the 1080 due to the power regulator design on the Founders Edition.
At this point, no one *really* knows how well FinFETs and Pascal can overclock due to the inherent board limitations of these reviews. It's doubtful that there's an actual thermal issue with the product, so waiting for some hybrid coolers to come out may be a good idea...
Hi Cath
This support bracket not sure if will work in yours case as this is intended to use with single GPU,this is pretty much very normal on Single GPU,on SLI or TRI SLI I've never seen or never have such issue,have run TRI SLI or triple Crossfire in past(OpenCL render)
Coolermaster 932 is great case,have this case previously,then I swapped this case for newer HAF X which has been great case,just pain is doesn't have any dust filter and dust filters only I know are best for this case are from DEMCIflex something like this,have used those filters on my previous HAF X
http://www.demcifilter.com/c21/HAF-932.aspx
Regarding the Titan X Hybrid kits,they're awesome as they keep cards very cool,if you are using stock EVGA fan,those fans sadly you can't control through the Precision X SW,which is same as MSI Afterburner(I would say they're copied the MSI SW) or any SW,this stock fan is loud and running constant high RPM,tried to control this fan via fan controller or through the Motherboard header and still the same speed,due this I replaced the fan for BeQuiet PureWings and I always running this fan at 750RPM(which I think is around 10-15%),temps in my case are bit higher than yours,idle 25C and load 45C during the rendering,if I would run fan on full speed at 1450RPM then load temps are in low 40's or late 30's,you can check yours you can control small fan on the GPU,not the fan on Hybrid radiator unless you are connected that fan to the motherboard or fan controller(I've used both option and fan controller is best option for me),I hate noisy PC as I do work through the night and my PC is turned on 24/7 and mainly due this I'm running at such low RPM my fans like for CPU or GPU..
Yes agree regarding the CPU Cath,I would do same,I render in other SW and due thisn i7-5960x hasn't been option for me right now,but mainly the price,I wanted sell my old i7 4790k with motherboard and get i7-5960x,but this has changed as this now residing in my cousin case,he has been very happy when I told him,i will be giving him,early birthday present
Those RAM,but DDR3 I think my friend used on his i7-4790k,those RAM which you are running seems are OK,if they work for you then I wouldn't swap them there,in my case I've went with Corsair LPX as those has been in stock over here and they're been 2400MHz too and are 2X16GB DDR4,I've plan to put extra 32GB(2x16GB) end of the month,just waiting when they're in stock
Regaridng the motherboards,I bought as first Asus X99 Deluxe,this I've returned as this motherboard didn't supported 16GB RAM module out of the box,then I returned and went with Gigabyte which supported 16GB RAM module,but didn't supported Xeon and then at the end I went with current ASRock X99 Extreme6 as this baord supported what I wanted and plus supports too ECC if I want to
Here is the Phanteks Enthoo Primo SE,this case which I have right now,GPU stayed,just added EVGA Hybrid AIO and Corsair H100 v2,but motherboard and CPU is now residing in my cousin PC,on this motherbaord you can see effect of GPU "sagging",is not straight as should be,on older motherboards this hasn't been issue
And this one is Thermaltake Core X71,this PC has been my longest workhorse,has run X58 ASUS motherbaord with Xeon X5670 OC to 4.2GHz and 40GB DDR3
Hope this helps
Thanks,Jura
Hi there
Agree I would wait on aftermarket solution like from EVGA,MSI or ASUS,which will have 8 pin and 6 pin and should OC bit better than FE editions which are over priced,plus there is issue with fan too on FE,please have look on this
https://forums.geforce.com/default/topic/938256/geforce-1000-series/gtx-1080-founders-edition-fan-issue-/
Hope this helps
Thanks,Jura
You saw other vendors cards, they added already additional 6 pin power supply so they can run it faster as there was not enough power for OC
the highest benchmark score was not using DX12 at all but Vulkan so saying that 1080 is faster compared to standard 2 x 980ti SLI was a simple lie and misinformation .
Is the GTX 1080 faster with games DX12 than 980ti/Titan x OC on 1500Mhz ? and answer will be no it is not ! and I run my 3 cards at 1400Mhz no extra power needed as it use just 60-70% of 250W when rendered with iray so cheaper to render than playing games what I am not into.
but when 1080 is ready for iray it is worth update especially for the extra VRAM it offer vs 980ti for people that don't have good card or just render with CPU at this moment, but not expect the super clocked to be cheap and use less power as they can consume a lot more power than the standard 1080 what is heavy overpriced at this moment as with all new card releases so 2-3 weeks before the prices get down a little .
As predicted it was all smoking mirrors of marketing , however if I had nothing I would choice 1080 over 980ti just for the extra VRAM and nothing else, but would never do that over Titan X SC 12GB due to it hugher Vram
Titan X is not for the gamers it is more for the graphic workstation so I expect next year another one for the Titan X replacement and for sure with more VRam and better speed for rendering .
Yeah I just figured out it will not working for me with 3 cards so I ordered MSI Gaming Series Graphics Card Bolster
I love the red case from the picture , my fav color .. I updated my Haf 923 with the side door and other stuff from HAF X as they match actually with the side panels and other accesories , HAF 923 was amazung for air cooling it keept my Titans at 67C on full load before I installed water cooling .
The original EVGA fans working fine with Precision X 16 and can be well controlled also they working fine with the control soft from Corair H80i v2 CPU USB water cooler I am using and you should control it also using V control from you GA APP center that I hate so much lol as all the APP center apps, at the speed you running them the cooling will be not efficient you need to slow down . The medium balanced speed give the best result for both cooling and automatic improve the GPU performance , because at full speed you losing the power to GPU , there is other way here to install second fans and use the mother board to control the temperatures as I had before , if your MoBo support additional PCI-e power supply you can use fan spliter 3 female to 3 male and use both fans controlled by Precision X 16 or just plug them to MoBo
I hate Gigabyte MoBo, the bas support that you have to wait 2 months for reply, the nonsense bios and other stuff, year it support 16GB sticks as I used it just one week ago on X99P-SLI Mobo but then it stop recognizing 4 th stick so total not what I wanted , the ram profile don;t even works so nope and returned . But I love Asus X99-Deluxe , it does not support 16GB sticks but I have My Corsair 8x8GB and they are very well supported for this MoBo , plus I really enjoy the Asus software and the rest in the past , not to mention the WiFi, and fan extension module , so a lot of good stuff for the money plus I can run my 3 titans x at 16 x and still have one more free pci-e for single profile for M2 or USB 3,1 card or maybe I just get the single profile EVGA graphic card to run my additional monitor .. I am happy with the price and what it offer also the new bios updates fixed previews problems , the last choice I would go for if I have too is Asus X99-E WS/USB.3.1 but always out of stock and I am not like in the mood to spend $520 at this moment but that would be something I would like to try out if I ever decide to get 4th Titan X or better card in the future.
Regarding you case I have more space on top so I can have double side fans on my GPU radiators and still far away from my MoBo and RAM
it is like putting your lower part room on top , also I can install my CPU water cooler outside the case with as big radiator as I want , beside the H80i v2 double thick radiator with double fans keep my CPU at 22C on idle with 21C room temperature so perfect . I did not want this huge thing covering almost half of my CPU so the extra opening for water cooling was just right when I need it , now I am thinking I should go with 280mm radiator and mount it on the side , but next time for now I am good no complains .
BTW I just read that the Asus X99-Deluxe usb3.1 can even run 128 MB when the ram profile is activated so adjusting need to be done under Bios , and that all on i75820K But all you need are Corsair Dominator Platinum Memory to even begin with and that are $1,800 costs so insane price
On GA-X99P-SLI you can run 16 GB sticks easy to 64GB as I tested before with cheap crusial DDR4 16GB sticks 2400Mhz $200 for 64GB
coming back on the cases , I am using magnet fan filters I purchased on my Haf-923 , works well
Hopefully today evening I am finalizing my new rig and I am still can't decide if I want the 3 GPU radiators outside or not as I dislike the pipes across the middle of the view but I would need some hardware to mouth it on the sides , I was thinking to purchase 360 mm cabinet cooler , remove the 3 x 120mm fans and replace with the GPU radiator for more esthetic look with a nice frontal grill on the side of the case ... just making it my own lol
The problem with comparing gaming stats and extrapolating to rendering presumes that Nvidia allows their consumer cards the same performance gains for rendering. They have folks spending mega cash on commercial cards, who would be less than impressed with some card costing 10-25% of the price offering similar performance or better.
I'd wait until the the reviews include comparrisons; drivers don't support IRAY at all atm; so currently, my old 640GT with 2GB of GDDR3 passively cooled offers better rendering performance than 2 x 1080 combined (or any number of em).
Hi Cath
Yes this will not work with yours and this MSI should works there
I went with Phanteks as well only due the color and I wanted to do same with my old HF X as this case I loved just due the caster wheels,with full gear has been very heavy and current mine is very heavy too,I'm running 2 SSD and 7 normal HDD(4 3TB and 2 2TB SSHD and 1 old 500GB which is my workhorse and mainly is scratch disk),agree that case have probably best air cooling and is very quiet what I liked most on that case
I did tried that and went with different fan,bought BeQuiet fans like for Corsair and for Hybrid,usually I'm running fans at 750RPM as most during the day,during the longer renders then I will up to 850-950RPM as most and for GPU too I'm running mostly how temps are and I usually controlling the if doesn't downclocking
I've been trying to control fans via motherboard,but I went with different route as Phobya fan controller which works for me and controlling fans on Corsair and EVGA through this as Corsair SW doesn't want to control those fans alhough they're PWM,its the issue of the new V2 SW i think and I now I'm uisng SIV64 which is much better and works flawlessly for me
Agree about the Gigabyte,I've owned two of them and both failed,Asus X99 Deluxe this board I bought,but sadly returned that baord as didn't work for me there,but agree is great board,my next board will be probably Asus Z10PE as I want to have 2 CPU and stay with 2011-3 or I wil stick with this,on this I will decide later on
This case has been designed for watercooling,there is lots of space for radiators and if I would remove drive cages etc then I would have space for radiators too,on bottom I can have 240/280mm or 480mm if I remove drive cages,on top I think 480mm is biggest and at front 240mm,if I want to go with WC loop which I will be doing if I will be putting extra GPU in coming months,that's plan
Regarding the putting larger radiator,if temps are really low there,then I wouldn't bother at all with this,if its for look that's different story,but if temps are low,I wouldn't go with larger radiator,in my case I went with H100 as I've used earlier version on X58,but this one V2 I think have noisier pump,many people wouldn't notice,but if you are running fans on low RPM you will hear the noise of the pump,spoke with supplier and he happy to send me updated version of the pump what they use and I will take them for this or I will retunr that and put there my old Noctua D15 which I've still from my previous builds and Noctua already sent me mounting bracket for 2011-3 and I will put money towards WC loop which I will be doing
Push/pull configurations of the fans,I tried that and temp difference has been only 2-3C on CPU and on the GPU temps has been I think just 2C lower,due this I abandoned this and running like is it
Not sure did you investigated to do full custom WC loop this should be much better option although expenisve,but will looks much better and without the downside there or you can have look on EK 360 Predator which have drybreak system and you can add there GPU waterblock etc very quickly,this is what I've used on friend build and he is very happy with that system,he running 3 GPU plus CPU with two 360mm radiators
Yes those magnetic filters are best,those above DEMCIflex are magnetic there too
Regarding the putting GPU radiator outside this depends Cath,from my pint of view I would try to put them to the case if case allows,if doesn't then you need to improvise there,but looking like you are already improvising which I like,this cabinet cooler I think I've used once something simialr in past and has been from Zalman(Zalman Reserator V2 ) and few other solutions are there too,you need just have look on this
Please have look on this gadget,I've same and works awesomely,its great monitoring gadget and display,its graet from one point of view,you don't need to have openned all those apps to monitor and if you need help with this I'm very happy to help you,I'm using this for few months and works great

Hi Again,
I love the gadget monitor very cool , I may get one as well , I love to control my workstation especially when I am running heavy load and OC the system .
I was thinking so many times about Central Water Cooling but I will do that if my system is final and work without issues for some time, I study it and I can do it , I just need more confidence , that would fix some esthetic issues but I will need a very good one to cool everything efficient so need to research more and get more familiar , I was thinking that when in the future I get one more card then I will have to change all plates on my titans for water cooling so it is little investment again and definitely not for this year as my budged is spend completely so no chance .
I checked the fans grill bracket for the 3 x 120 mm but need find cheaper or do myself from the old side panel what is nice 4 x 120 grill just need to cut out and reducing cost to $19 lol I could put them on front but the cooling was not as good as on top , outside would be perfect and I can put inside on top 240m big fan and I have tones of good fans to cool nice the rest of the system and problem solved, not really a problem but it don;t give me a peace .. I will think about today and decide what to do as I got one more idea but need to test the air performance before
I was thinking I may go with this case in the future .. really love it http://www.amazon.com/dp/B00XCA86OM?psc=1
and you can put tones of stuff there , no worry about your pci-e sockets anymore and at last see the good side of the cards lol and even Central water cooling for the future .. really nice and you can stack your rigs one on top of another .
I would love to have 2 CPU but for now not thinking about much , the ideas make me obsessive but good to have some dreams left for tomorrow and enjoy today what you have already . Things change too fast today , I want quantum processor ! LOL maybe I will be still alive to see it in action in consumer rig .
But for today I am preparing my finger tips for the screwdriver and finish this thing finally including cable management as right now it looks like my PC vomit with the cables since I was testing a lot of stuff last week and put a lot of extensions . We see how it goes , wish me luck
Aargh, all this hardware pron talk is making me want to build another computer.
No! House move.
But octocore and twin TitanXs with closed loop water cooling.
No!
First benchmarks for the new Haswell replacements have started to appear...
http://arstechnica.com/gadgets/2016/05/broadwell-e-arrives-testing-intels-10-core-1700-desktop-cpu/
Shush, I'm easily led when it comes to upgrading my hardware; Cath's fun isn't helping matters either.
The only shoking here is the price , I expected little better perfomance for the value
It it was not emergency I would not even bother yet as it is not my time for upgrade or updates , but when one thing get wrong the rest follow and I was sucked into the rhythm lol I blame windows 10 for everything .what happened after , 1 upgrade day turned into 1 week .
First the pci-e socket damaged the MoBo , after upgrade and fix Windows 10 decided to upgrade itself and locked all my SSD and SHD on the way , and it did so good that I had to format everything , all my system all my projects everything , no one command was working on the locked SSD or SHD error after error , finally I got some software to browser the files ( command prompt was not usable ) and found maps created by Windows 10 about volume information , system files and other stuff where they should be not even exist as that was not even MBD , after 3 days finally recovered important folders and files leaving everything else , as by copying one of the wrong folder in convert directly my new SHD to EIF protected system partition and hides it, so stupid never happened before in 19 years , I installed my windows 8.1 pro and keep running the new hardware with some stress for test and guess what was next day when I open my computer ? windows 10 Pro it upgraded itself even after I turn updates down .. fantastic , talking about fun ..
Now I have little fun as well but don;t want to experience it again , it was very disturbing and my clients not happy about the delay .. well what you can do , when the backup of the backup not working you got simply death pants and nothing more .
I don''t feel sometimes my computer belong to me anymore , like in chains of MS , the times that clients was the Kings and Queens is sadly over .you can't even choice your own default browser by simply clicking the browser button or change the browser setting it will turn over to Edges next time you start , but I removed all the default win apps and set my own so now it finally stopped , but what can do a grandma with this if she don't know how ? Thank God I am a super glamma LOL
I want to move next year so I may wait with the central water cooling and do it when I settle down but definitely not octocore I am obsessive but not possessed
I have to run first my 3 Titans X until the fans fall off and the pipes leak but as with all hardware you never sure what tomorrow bring .
Quick update:
I posted that the release candidate for Cuda 8 is allready available.
Someone pointed out that the official release of Cuda 8 is scheduled for August 2016 based on a blog post in April.
https://devblogs.nvidia.com/parallelforall/cuda-8-features-revealed/
In any case I deceided not to preorder the pascal cards but to actually wait and see OctaneRender or Iray benchmark results.
well someone here bought the new 1080's
http://www.daz3d.com/forums/discussion/89996/gtx-1080-iray-support
100% agreed on all points Cath. From a pure core count perspective, a lot of the benchmarks were suuuuper fishy when they first came out. The SLI one was the most egregious, but more because of the simple fact that SLI scaling hasn't worked for a lot of games these days because of AFR. Given proper SLI/AFR support, it's hard to beat two 980Tis.
Having said all that though, I'm *extremely* surprised at how the boards were designed from both a thermal and electrical standpoint. If the FE design is indeed their reference design and it already has thermal and voltage-scaling issues, it may not bode well for overclocking down the road.
I personally will be buying a Titan X when they drop in price. Probably not a hybrid cooler since I won't do high OCs, but it should be more than sufficient to beat the 1080s...
A lot of people are throwing around info here, and not all are understanding it. The 'Fan Issue' is a small issue. The big issue (in the minds of those who understand what is going on with the board) is that thermal/power throttling is happening after a few minutes of high-load usage. Now, being brutally honest, the issue isn't the card, but the default settings in the driver/firmware for fan speeds at varying load temps. It doesn't ramp up quickly enough, and you end up getting 'spikes' of the fan jumping up to full (100%) tach, then slowly dropping back to a more tolerable level. And when this happens, it indicates the heat/power got too high, so the GPU throttles back on any OC'd frequency.
If you just run the card at stock speeds, it holds up pretty admirably even at full load. But when you start overclocking, you will need to put your GPU fan at a fixed (and rather high) value if you don't want it to 'choke' out and be constantly revving/slowing the fan. Of course, running the fan at full all the time works perfectly.....except for the massive noise.
@Mec4d, comparing heavily overclocked and water-cooled cards to the base 1080 at stock speeds is hardly accurate. And nVidia has always (ALWAYS) worked on supporting OpenGL more than DirectX. So their driver support for DX12 isn't yet up to snuff, that's okay. Radeon/Catalyst OpenGL support has had buggy issues for YEARS. But AMD cards run DX just fine. And if you are more concerning with Rendering rather than Gaming, why is DX12 support an issue to bring up? Most rendering, modelling, and animation software uses OpenGL for its interface, NOT DX.
ASUS already has specs out on it's 1080 GTX STRIX SC card, with dual fans, special heat-pipes, additional power connection, and its retail price. Supposedly will be available as soon as it can get into stores. And a good bet is that with the additional cooling and power, it will OC a lot better than a Founders Edition 1080. And for a lower price (Superclocked STRIX version listing at $650.) https://www.asus.com/Graphics-Cards/ROG-STRIX-GTX1080-O8G-GAMING/
And some of the OC forums are already doing LN2 mods to the 1080.....I'm almost afraid to see what kind of numbers they are going to post when they get it up and benchmark it. Imagine a 1080 GTX running at 3000 MHz......
Thats... not what's happening. The clock is scaled back due to the increased temperatures, not because the fan speed is dropping down and indicating heat/power got too high.
Tom's has a pretty good chart http://www.tomshardware.com/reviews/nvidia-geforce-gtx-1080-pascal,4572-11.html which shows the temperature curves. The problem is that the fans cannot provide enough thermal cooling with a full load, not because the fans cannot ramp up fast enough. It also clearly shows how the 1080 *does* work properly by delinking the temperature-fanspeed feedback and running the fans at 100%. That indicates a few things, namely:
But when Nvidia stated it was 2 times waster they did not used SLi or Direct X 12 at all , no games not rendering total different story and heavy overclocked , who care it was faster on something nobody usually use , My cards are not heavy overclocked they don't need power adjusting to run at 1500Mhz , the standard super clocked is 1400Mhz ,
and never use more than 50-max 70% of power where overclocked 1080 can run even to 300W for that reason they added already extra power . But beside all the overclocking , we still talking about the standard speed of the card and there is not way it can run 2 times faster as no one benchmark done until today, prove it .
and to have 20% more of speed I would rather spend little extra and get more memory , plus we completely don't know how the cards going to perform in rendering
1080 will evolve in something cool but for now you have what it is and it is not worth the investment at all at last not for today until the prices drop down and better build start to selling . And that will be heavy overclocked one with all sort of cooling to keep the temp down and good PSU if you want to run more than 1, then what , do I need to put my cards in liquid Nitrogen to prove again they can run faster ? lol
I really don;t care , I just wanna see real benchmarks for iray that is all , no matter it will be the standard or overclocked until then I don't care about speculations as that means nothing , last time you stated the standard 1080 will be 2 times faster based on all configurations , well it is not, other way I would selling my cards on ebay already .. well at last when iray is ready .
The dream about 1080 with only 180W power that is 2 times faster than TitanX is over .. go and see new REAL benchmarks they don't lie as they paid for the cards from own pockets .
Either I didn't communicate it clearly, or you misunderstood. I wasn't implying the fan was controlling the behavior, but was simply a symptom of the heat/power increasing, and the fan not being appropriately increased until it had reached the throttling point. At which point it maxes the fan, cools down, the fan reduces back too low, and we start the cycle over. This is what can be seen in the graphs of the fan behavior under heavy GPU loads.
I've seen plenty of the graphs. The most telling is that if the fan is manually set at 100%, then the Founders Edition cards will run at 2100 MHz with temps staying below 80C. The problem is that the current implementation isn't handling load vs fan speed correctly.....it waits too long before ramping the speed of the fan up, and then ramps the fan very slowly. When the heat build-up gets too high, the GPU throttles down and the fan goes to max. Once the heat is dissipated sufficiently, the GPU unthrottles, and the fan slows down. And then the cycle repeats.
It's a symptom of the current firmware/drivers being gaming based, where GPU load is very transitory. If the load doesn't stay high for more than a couple of minutes, the cooling in the Founders Editions is sufficient. But if it lasts longer than that, it becomes a problem. Furthermore, if it goes straight to max load, and pretty much stays there, it happens even faster.
Since the card operates at full load without temps being an issue when the fan is set to 100%, you can't really say the thermal design is 'inadequate'. Even overclocked 30%, it holds up just fine that way. It's only when the firmware/driver is controlling the fan speed that the issue manifests. That points directly to fan control issue. Yes, a bigger and more capable thermal solution will also work, but only masks the real issue until you hit another heat/load level at which it will likely also show the same behavior.
+1 exactly ... I saw that ... I actually believed everything for a moment until I got hint from sommeone that own the pre release ...for that reason I purchased different card and saved myself a troubles not only with the card but also late support for iray .
Um, the BASE clock on a Titan-X is 1000MHz. http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-titan-x/specifications I'd call a 50% jump a pretty heavy overclock. Even IF 40% is factory-based overclock.
Hm, I don't recall saying anywhere the 1080 was twice as fast as a Titan-X. Well, I did (I think) note that if you overclocked the 1080 to 2144MHz then it was over twice the base clock of the Titan-X. And although it has fewer cores (2560 to 3072, that's about 20% more in the Titan-X) that even at base clocks, it would typically out-perform it pretty well, and get up toward double performance. When you start talking about overclocked Titan-X's (anything over 1000MHz) that isn't the case.
I think you consider anything that is running at its factory speed as non-overclocked. But technically, anything over base specification is an overclock. Hence why many of those cards are called 'superclocked' or such. It's simply a factory-set overclock.
Agreed, until they get Iray working with the 1000-series, a lot of this is just conjecture. Some of the numbers show one thing, others show the other. It'll take a few months for the driver/firmware issues to shake out.....
Factory overclocks, like the ASUS Strix, or the Zotac AMP!, or the eVGA SC/SSC/FTW/Classified sereis will always out-perform the reference card. That's the way it works. Run the GPU faster, you get more performance (until you hit a thermal, power, or bandwidth limit.) This is why I always try to compare architecture changes ONLY with BASE (reference/founders) clocks and coolers. It's the only way to see what the gains are, without skewing things.
I'm looking forward to those benchmarks myself. I think Pascal (once the maiden-voyage shakes out the bugs) is going to be a real game-changer. But I'm still trying to find where I said that a standard (i.e., founders edition) 1080 at base clocks would be twice as fast as all configurations. I made some statements about overclocking potential, and compared THAT to other cards at base (reference) edtions.....and at raw clocks per core, the potential IS there. And I KNOW I clearly said that once you overclocked the 1080, it would go over that 180W consumption. Heck, I believe I even mentioned that at 2144MHz, they showed it at consuming about 250W.
And I'm keeping up with the current benchmarks, but remember, there are still driver issues, the fan/thermal issue, and probably others that haven't even been noticed yet. It's only been out less than a week......And even the gaming benchmarks (that aren't tied to DX12) are showing considerable gains from the Founders Editions base 1080s, DESPITE all the issues. I think once they get the release a bit more stabilized, we'll see more of the promised gains.
We can agree on many things and that is true, I am not arguing with you I just see the facts for today .
There is a difference between Overclocked and Super clocked , Super clocked are the cherry picked GPUs that can run faster than the regular standard one without any adjusting in voltage or memory water cooled or not , they have higher standard clock and so the boost and many of them running much faster than the specifications on the page , as no one card I own match any specification as they run match faster and in most case 25% more than the specification page
But my point is that the standard 1080 they used for the public test was heavy overclocked and the benchmark numbers will never reach the speed on consumer machine . It may be faster but not for us , if Nvidia want they can run Titan X 70% faster in iray as it already is but for that you need to pay 3 times the price , so thinking that 1080 will be better in iray make not sense for the people that spend so much money for multiple cards . And maybe one M6000 is slower in iray than 1 Titan X but 2 M6000 are faster than 2 Titan X .. it is controlled by iray software and have nothing to do with graphic card specifications or the speed of GPU it never was that is how business is made . So what we can expect from super clocked multiple 1080 in iray is up to Nvidia and not product specifications and since Nvidia see Titan X 12 GB more as workstation card than game there is a chance thing can change for better soon regarding rendering .
And if 1080 run soon 5 times faster in the games I will be happy for the gamers but for me it will have no value if the GPU is compromised in iray .. I can just hope for the best , bird in the hand is worth 2 in the bush lol
Same here. We just interpet them differently.
Actually, they DO have adjusted voltage and current limits. They're just done on the board, at the factory, based on the increased cooling performance. Those 'cherry-picked' GPUs are mainly for being able to handle those increases. Too many impurities or crystallographic faults in the silicon where important gates are result in failures at higher power/voltages/frequencies. This is why overclockers look for certain 'batches' of chips based on the data printed on the chip (which includes the batch date.) The ones that had a very good silicon ingot the wafers were cut from will have fewer potential issues, and thus can be pushed further beyond baseline specs. Most modern GPUs this isn't a big issue anymore (like it was back in the 90s and early 2000's) so it's more a matter of having sufficient cooling, increased power and regulation, and better heat transfer......all hardware the AIB's upgrade on their 'performance' cards.
It was overclocked in ONE demo, and they pointed it out. Hence why they showed the 2144MHz clocking and the temp (67C)...but they audience couldn't hear the fans blowing at full speed since the boxes were backstage.....And the graphs did show where the power consumption was estimated for at those overclocks.
As for the 'business' side, I think nVidia wants to push 1080/1070 right now and Iray WILL be faster on Pascal than on Maxwell. I'm still betting that the next quadro/titan generation will be Volta, not GP102. I think GP102 will be the Titanium cards. And the Volta, if it follows even close to what nVidia claims, will be another big jump. So Quadro and Titan will get even MORE powerful. But that's at least a year away, maybe more. 1080 won't be HUGELY more powerful than top-end Quadro or top-end Titan-X, but it will be slightly more. Most businesses won't pay a premium just for a small (10-20%) boost with less support. But when Volta debuts, they'll pay $$$$ for those kinds of boosts.
Yes, I know they have hamstrung render performance in the drivers in some generations to prevent them from competing with their more professional-oriented cards. Kepler was a perfect example of this, and they continued it with Maxwell. It's nothing new in the computing industry. It's easier typically to mass-produce one thing, then sell it at various price-points based on artificial limits. Given the needs Pascal was created to solve, I would think they're planning more along what I described. GP102 might have an 'interim' quadro/titan....but I think it'll be quite limited....And Volta is where they'll truly bring out the Professional-level cards.
I can't see it running quite THAT fast. 3x, maybe up to 4x, in VR, where the simultaneous Multi-View basically doubles performance for stereoscopy.....but just plain render/pipeline speed, It's about a 30%-50% gain over Maxwell at base clocking (or will be, once they get the drivers fixed.) That's pretty impressive, and doing it for less power is even better.. But it isn't the GPU that is compromised.....it's usually in the driver or firmware. That's almost as bad, but it CAN be gotten around. Just a LOT more effort to do so, and a lot of risk to the hardware.
And I wouldn't recommend to anyone to go out and buy the Founders Edition cards yet. There's a lot left to do for Pascal to be really evaluated. Just like EVERY initial hardware/software release. If they need performance NOW, get a 980Ti or a Titan-X. If they can wait until Pascal finishes its shakedown cruise (and starts showing the gains it should and is fully compatible with Iray and such which I think it will) THEN they should wait and (1) let 980Ti/Titan prices drop and (2) see what the actual performance of Pascal is when it's no-longer 'bleeding-edge'. Then I think they'll go with the 1080....or wait for the 1080Ti.
@hphoenix
Thanks for your reply , it sounds more rational , however
I don't agree one one point a about voltage and I have no ideas where you get the info from or just think it is this way but this is not and you have to be corrected
the limits on Titan X standard is 250W no matter it is superclocked or not there is only 10% room for extra voltage and the card can't use more than 275W at its power setting at 110% , if that was the scenario you will need 1300W to run only 3 Titan X and where is the power resource for the system ? I run 2 Titan X SC for months on only 800W PSU without any issues , EVGA recommend 1200W for 3 Titan X and the system so they can't consume more power I go ahead with 1300W as my CPU use 140W so I wanted to have little room , there are well bios that allow the voltage at 1,3 v but that are mostly used for benchmarks under very good cooling conditions like liquid nitrogen but not for the regular consumer, the air cooled super clocked Titan X can't from the design point get over 1.2 v , but because I have original 2 Titan X SC air cooled that run at max allowed 1.2v and 1 original Hydro , there is no difference in voltage, power usage or memory speed , when I upgraded the air cooled to Hydro kit I was talking to the EVGA technician if I have to flash the bios to get the best of that due to the vol limitation , and he said nope as long the GPU stay cool I can turn the boost higher without worry about the voltage adjustment . So you see there is no voltage adjusted and usually they use max on boost 1.16V never saw even 1,2 v so the scenario is 0.87v idle to 1.18 v max and not 3.0V as that would be crazy for so big GPU anyway but there are fans that pushing to the limit and flashing the bios over the allowed limits
There are also 2 scenarios, game and rendering , with the game the power limits will run on the max pick, with rendering there is still at last 40% room as Titan X never used more than 70% of Power while rendering and when you use caustic and architectural samplers the power usage get even lower to 50-60% only so in this case it don;t even need the extra juice
but again a lot of your info is coming from the gamer scene and not actually for using with rendering and there are 2 big difference if that was the facts I could not run my 2 Titan X SC on 800W for months last year it would be over the moment I start to play games with as I would not have enough power to even run my CPU with , not to mentions the rest of the rig as the 2 cards would consume 700W on higher voltage settings . Well I played The Witcher since it came free with my cards but the voltage never go over 1.19V no matter original Hydro SC or Air SC or standard at 1457Mhz
