Daz3d studio rendering with GPU fails to CPU

GaryH

When you say you tried different VM sizes, how did you set it?  Try setting the min and max sizes to be the same so that Windows won't dynamically manage the size.  On my 32 GB system I've set it to 48 GB - and yes, you'll loose 48 GB of space on your SSD to the pagefile.

What I've found is that DS continues to allocate more memory as your session goes on, especially if you're changing things like materials or lighting.  This allocation shows up in the "commited" memory, not the "in use" or "working set" memory that you see in Task Manager.  Open the Resource Manager from within Task Manager to see this.

When the commited memory reaches the physical RAM amount Windows is supposed to dynamically allocate more pagefile space. It is at this point that I've seen DS drop to CPU.  I have not experienced the drop to CPU since creating a fixed sized pagefile of 1.5x my physical RAM.

Of course, this doesn't explain why your 1070ti machine works fine.  Still, I'd give this idea a try.

How many cards have you

 I got 2080ti in this PC, and 1070ti in other (same thing happened with 1070ti on this pc, so it muse be a sofware issue

If you have two 2080ti, then try with just one; swap to test both. If you haven't, do you have a friend that will loan you one? Failing that, is there another PC in your household you can use as a test?

I can't borrow a 2080ti, and i can0t test it on second PC. I would have to switch the PSU, and its all over the case, cable megagment and such

There are various test scenes available in Blender; it is possible to use CUDA or OptiX (see image).

If you download them and the latest Blender, you don't need any real knowledge of Blender; double clicking the GPU scenes will open it and F12 will start the render. I don't know if they automatically use Optix if it's available.

You can go to Edit > Preferences, then click on System as shown in the image. OptiX is an option and you can disable any cards ( I presume), so they don't use it. I tend to use CPU as it's quicker than my 980ti, which is why None is checked in the image. I do also use bother as Cycles does out of core rendering.

You could try with and without; https://code.blender.org/2016/02/new-cycles-benchmark/

I'm suggesting it as an option if there are no others available.

I'm try this now, thank you

PS: what image?

This one; no clue what happend to it.

(I can even use CUDA to render using CPU only, just by selecting it.)

Okay, so, I had it at minimum 48000 and max 62000.

I changed it now to 48000 and 48000

For now I'm rendering 50 mintues, no fails yet after the page file change and restart of PC.

Damn... I really hope this works!!!

Nope. After 1h40m it failed. And it kept failing same as before on next renders :/
