    Oh yeah, you are going to be sooooo happy with a 1070 or even a 1060 for that matter. They use a lot less power, too. You should be totally fine. It may not be a bad idea to upgrade that ram though. I'd love to see your test results from sickleyield's benchmark thread before and after your upgrade!

    Here are those numbers. I'll put them in the benchmark thread, just in case anyone is interested. :)

    This is a video card/memory upgrade comparison for a 9 year old Core i7 965 Extreme in a Rampage II Extreme. Prior to the upgardes, I deleted the two spheres from the benchmark scene, because it looked like it was not going to render with them. I did leave the spheres in for the post upgrade renders. I'm not sure the iterations are accurate. I did one render where the iterations were included with the render information (in the log file) after the render completed, but no other renders did that, so I went with the last line before before the render ended.

    6gb RAM
    Asus Geforce GTX 480 with 1.5gb GDDR5 and 480 CUDA cores
    Neither have Optix enabled

    CPU and GPU
    Time: 59 min. 46 secs.
    Iterations: 3920

    CPU Only
    Time: 59 min. 22 secs.
    Iterations: 3938

    GPU only would not render.

    12gb RAM
    MSI Geforce GTX 1070 Gaming X with 8gb GDDR5 and 1920 CUDA cores

    CPU and GPU
    Time: 5 min. 36 secs.
    Iterations: 4775

    CPU and GPU - Optix Enabled
    Time: 3 min. 58 secs.
    Iterations: 4799

    GPU Only
    Time: 4 min. 57 secs.
    Iterations: 4800

    GPU Only - Optix Enabled
    Time: 3 min. 23 secs.
    Iterations: 4794

    Needless to say, I am pleased with the improvement. :)

    ...so a 1070 doesn't necessarily need 16 GB of physical memory?

  • CapscesCapsces Posts: 465

    Apparently not. The box says it requires 8gb system memory and that 16gb or higher is recommended. I have 12 and I'm not seeing any issues. Of course, you want to check the requirements of any card you consider purchasing.

    I only have 8 GB DDR2 in the system I currently have the card in. The only problem I've seen so far is if the scene uses too much RAM so it starts swapping, this makes the system almost totally unresponsive while it takes place.

    In a nutshell, don't overclock more than whatever the factory overclock is - rendering abuses consumer cards far more than playing games.

    Having said that, if your renders are only for a few minutes, and there is more time when you're not rendering then the strain is less.

    That's not my experience (1070 factory overclocked). GPU load on my card is rarely 100% when rendering, I think on average it's about 60-70%, and memory always runs 5% below max (~1900 / 2002 Mhz). Running the Heaven benchmark test which I assume simulates a 3D game puts a lot more strain on the card. I'm not into gaming though so I have no experience with real games (would probably run terribly on that machine anyway - old Q6600 2.4 GHz CPU and 8GB DDR2 RAM).

    A tip (though it only seems to work in Windows 10): if a render has finished and the status window has closed, you can get it back by clicking on the DS icon on the taskbar and then hover the mouse over the small DS window that pops up. Easier than opening the log file.

    ...I know, I frequently deal with that even with 12 GB on large scenes during CPU rendering. To optimise upgrading my current system would cost me around 650$ (OEM of W7 Pro, 24 GB tri channel memory kit and the GTX 1070).

    ...exacly, that is why Quadro GPU cards cost so much more as they are designed to handle the high loads rendering for long periods of time.

    Is there any information to back up this claim? Couldn't find anything on Google.
