    Water cooling is fairly inexpensive these days and not to hard to install. If you have a mid tower and its quite full you are going to have a lot of issues with overheating. You will need to put in the max amount of fans as you can.

    I'm getting the distinct impression that an old laptop with an onboard nVidia GPU in a non-air-condioned room in the tropics isn't the ideal environment for running DS4.8 then... ? ;o)

  • Even if you have a beefy GPU ram, you still need a lot or CPU RAM even if you are not using CPU rendering with iRay,

    Why?, IDK but this image proves that. I have only 8Gb of ram, and I need virtual memory for accompleting the task, regardless using GPU rendering mode and not using all my full GPU memory for that!

    Absolutely! I crammed in whatever it would take. Mind you, on a particularly hot day, even that isn't enough to prevent a little CPU scream during an Iray render. I'm guessing that means that the CPU is working hard, so I'd better watch what I do with it or I'll be replacing that along with the graphics card, which wouldn't be good.

    CHEERS!

    HI EVERYONE, I have this post in another discussion realted to this but how knows maybe I can have some awsers here too, this is the deal, I know that this maybe silly but I just bought the Acer Aspire M3450-UR30P for a really good price (100), the mobo is Acer RS880PM-AM, I want to buy the GeForce GTX 750ti or GeForce GTX 690 (if I can find the 690) to help with the iray rendering time, cuz actually it takes from 1hr to 2 1/2hrs on 1100x1400 image size with 2 Genesis2 full dressed with HDR lighting, also I want to upgrade the RAM first to the max and I know that I gonna need a PSU, so plz any help, I don't have a lot of money and I don't know what GPU get, if I can reduce the time to 30min would be nice, also a new pc is off the grip, and this PC works good for me I made the jump from Dual cores, I been reading a lot here and there and everywhere and theres not a really good answer, some say more CUDA is better, others VRAM, and others Processor, btw, the GPU that I want to get it would exclusive for rendering, I not planning to atache any screen.

    This are full specs 

    Product Description: Acer Aspire M3450-UR30P
    Processor: AMD FX 4100 / 3.6 GHz ( 3.8 GHz ) ( Quad-Core )
    Processor Main Features: AMD Turbo CORE Technology
    Cache Memory: 4 MB L2 cache
    Cache Per Processor: 4 MB
    RAM: 12 GB (installed) / 16 GB (max), DDR3 SDRAM, 1333 Hz, PC3-10600
    Hard Drive: 1 TB, standard, Serial ATA-300

    Definitely upgrade your PSU, I'd go for a 750w to be on the safe side, most GPU's say a min of 400w, but, you want more just to be absolutely sure that everything else can keep going when the GPU is running. I've got a 750w in mine and it keeps everything running smoothly.

    Nice though that GTX690 is, I think it's rather old. Pity, as some of the specs were better than newer models around now. It had 3072 CUDA cores, where a 960 has only 1024. You will be paying serious money now for a card with 3072 CUDA cores. The cheapest 4gb won't necessarily be the best. The Asus Strix GTX960 offers decent performance and costs £200, it's what I'm going for and I have 16gb of RAM and a 6 core AMD FX6300.

    CHEERS!

    Cores are good to compare cards from the same generation, but a much less effective method when cards are from different ones.

    Even when an earlier card might actually offer very slightly better performance, if it has less memory, the card gets used less; a card is only faster if it is being used for the render, if the scene drops to CPU, then the card is slower as it will take however long the CPU takes. smiley

    There isn't one thing that is better; you need to take a holistic approach. It's a combination of processor, memory, graphics, storage (and when rendering is involved) a very good PSU. Storage is the least vital; SSDs are nice, but offer little benefit (if any?) to rendering. So if you need to move cash into the card from somewhere, then this is an area - it certainly shouldn't be from the PSU.

    Set a budget then allocate resources; try and squeze more into the graphics card used for rendering. But too much will make the system sluggish when setting up the scene, and it will even have some effect on rendering even when the graphics card is being used.

    I don't reccommend AMD processors in this instance, although they can be used effectively. They normally cost more to run - something to bear in mind when leaving the computer on longer; a decent i5 and preferably an i7 are a better option. But it is about budget and getting the best possible for what's available. I also don't recommend overclocking, unless you don't mind shortening the lifespan of the components used for rendering; I have my machine set up with an over clocked profile - I rarely use it; it is there, however, if needed.

  • RogerbeeRogerbee Posts: 4,460

    If I were to move to Intel now, I'd have to get a complete new motherboard and processor and that would cost a fortune. AMD was the cost effective choice and I have found it has worked rather well, even with Iray.

    Why I said in my post they can be used effectively.

    Gotcha,

    My current GPU is an Asus and it has been trouble free since day one, so the Strix shouldn't be any different.

    I bought my first nvidia, a 970 strix, liked it alot; when the ti was released, I thought about it; I considered the fact that there will be a whole new architecture from nvidia next year, but that is next year; so I bought the 980ti strix; both are great.

    The one thing I did have to do on the 970 was removed the covers to tie down the one of the cables, it was catching on the fan; now in fareness to asus, it had been tied down, and manually spinning the fan didn't show the issue. I just added another tie over the one already on, which cured the issue.

    thnx for your advises ROGERBEE and NICSTT, and yes i7 it's good, but as Rogerbee said, I will have to get a hole new pc in other words, and just to get speed on render, now with all the toys inside we talking about from 1500 to 4000 (maybe), so with a limited budged thats crazy, I will have to face at lease 2 months of work just to have a big toy, when on the other side I can expent 300 o maybe 500 just to make my pc better.

    Thanks for the heads up, on reviews I've seen of the 960 I haven't heard about that, but, it's something to look out for all the same.

    Watercooling can be hit or miss, Custom or more expensive setups can work. I wouldn't recommend any of the current All-In-One units: they're noisy and not as quiet or effective as fan/sink in the same price range. But you might run into space issues with the larger heat sinks out there. (mine stands nearly 7" tall, but the whole system is silent and stays quite cool under load). Can't stress enough the importance of good cable management and fan placement.

    I have a mid range liquid cooling thats works emaculate. I can't even here the computer run. My PC never overheats or even gets hot. I have my liquid cooling, 1 HD/GPU cooling fan and an exhaust fan and my system never gets about 34C and I have a big system. I have a Corsair H80 and the only thing I hate is I have to clean the radiator fins from dust every couple months but thats it.

    Welcome. yes As I said, it was already tied down and the additional tie I attached constrained it by no more than a further 2mm, and likely about 1mm. It was exacting (no not exciting) trying to be sure I had found the problem; the wear on the fan, compared to the other one was hardly noticeable.

    I wasn't 100% sure, until I'd reinstalled the fan back in the computer, that I had resolved the issue. I think the problem arrose as cards can warp slightly when installed in cases without support, so the bending misalligned everything. I've done a tempoary fix to stop the warping, and am looking for something more permanent. I used to have a large Lian Li case, this had addition brackets to support expansion cards at both ends, this new case which is much smaller and easier to find space for (it fits under the desk without sticking out) does not have such facilities.

    All-in-one cooling (closed-loop) units are good enough; they also have the benefit of not risking the motherboard's integrety whenever the PC is moved. Admittedly something that is not a huge issue; not all motherboards have additional support around the CPU to reliably support the weight; even those that do, it is stil a lot of force.

    A good PC builder really pays attention to supporting that area and the cooler when shipping to the customer; I wouldn't buy again from a supplier that didn't bother. Although I build my own, so not an issue, but is something I reccommend folks consider.

    I used to have a larger Koolance system for water that I liked, I'm just not sold on the new AIOs. I picked up a Noctua DH14 for my recent build and I'm really happy with it. Agreed on the shipping, I also build my own. I've seen a few horror stories of people shipping their own builds without supports or taking at least their big heatsink out and trying to blame it on UPS...

    Are there any backplates available for your motherboard? (or maybe another case seller sells them separate?) It wouldn't be too difficult to have one fabricated if it's an issue for you. I'd think two or three long strips of metal would even help, so long as you have the clearance, just a matter of using a good spacer for the mounting screws.

    I never really checked the 960, but, some of the newer cards have backplates, shouldn't that make them less prone to warping?  I could understand that happening with just the PCB alone, which is how my current Asus is.

    The MB has a backplate, it's fine. Yeh the Noctua is a good cooler for sure.

    @Rogerbee

    The cards are fine, and designed to warp a little, but it does change their shape. Well I presume the warping is allowed for within their design tollerances. Personally, I prefer to support them though, I just feel it is better when removing cards that they aren't subjected to any unnecessary stress, and wonder what the twisting has done to installed cards.

  • RogerbeeRogerbee Posts: 4,460

    Ok,

    One day I will get a Strix. I could, if I so wished, raid my savings, get one now and then worry about putting the money back later. However, if I wait till after Christmas, I usually have plenty of money then and could get a better deal (I got a very good deal on my current Asus) and also, should I need to raid my savings at all, there would be less to put back.

    Decisions, decisions.....

    hello everybody!!! its been a nightmare this last 3 days, after checking prices on graphics cards i decided to get the EVGA GeForce GTX 960 SSC 4GB with a Antec 520w PSU, BUT, now when I plug the gtx I get stock on the boot screen and don't let me access to the Bios, and when I unplugged the card everything runs normal again, my question is does any one experienced the same issue??? plz I will appreciate any help!!!

  • fastbike1fastbike1 Posts: 4,078

    You may need to update the motherboard bios before installing the card.

    How old is the motherbaord? Will it support the GTX 960?

    about 5 years or 6, if I not wrong!

    That may be some of the problem. I would defintiely look for a motherboard bios update.

    I just got one for my motherboard and it's over a year old.

    The thing about flashing the bios, only do it if seriously necessary; but for 5 or 6 years, that is looking like a necessary. :) At least it is easier than it used to be.

  • RogerbeeRogerbee Posts: 4,460

    Well, I think my PC is running better now I've done it and considering the problems others have had, I figured it was worth doing. The newer graphics cards weren't out when I got this motherboard and so anything that helps it run them can only be a good thing.

    Hello guys, thnx a lot for your suggestions, but after 7 days, I know my mobo is trash, have to buy a new one, for now I have the 960 as a paperweigth until the new mobo arrive.

    btw the trashi locked mobo is the Acer RS880PM-AM, if someone have it and try to upgrade graphics don't even think about it.
