C4dtoa GPU freeze my computer

Hi!

I got a RTX 2080 ti card, and the GPU render keep freezing my computer. I know it's not production ready, but I need to restart the whole system every time it freezes. So not that easy to test the Arnold GPU.

I've gotten a failure on a nvoglv64.DLL file, but haven't understood how and why it fails, or if this is the recurring problem. The computer freezes before making a report.

I'm still on Windows 7, so maybe that's a problem?

I've updated my drivers to the latest ones 431.60, made a clean install every time, and tried different versions down to 430.86.

Edit: Just tried to pre-populate the GPU and it grantee freeze

Update! It didn't take many hours from my last comment that my computer crashed again. So I went and bought a new PSU that way stronger (from 850W to 1000W). And it seem to work! If you get many DLL errors it could just be that you have too little power to drive your GPU card.

I'm glad it's solved. Thanks for the feedback on this, I'm sure it will be useful for others as well.

I maybe found the solution and it were my PSU. I switched to another pair of cabel (My PSU can have three cards) and the problem went away! It could be that Arnold wants more power then RedShift. But I'm doing some more testing to find out if it's now stable.

Hi! Tested with Redshift demo, some lights, car paint, cube and a plain with walls, nothing to fancy. I don't know my way around Redshift. Added Brute Force GI with lots of bounces 7000. No problem at all.

But prorender did crash my computer and I got a different dll that were failing. ntdll.dll.

Other DLL that have crashed are: NVCPL.DLL,

Yes, very basic, can be a cube spinning with some lights. takes about 6 to 12 min before full freeze. I haven't tried other GPU renderers, but can do some testing tomorrow.

I got it to do a full GPU pre-population, I were wrong that this freezed my computer permanently only temporarily. But I got an error message trying to render. Sadly I don't remember what it said.

Buy the way, when I first got the card back in April, everything worked as expected and yes I've been thinking it's maybe a hardware issue.

Win 7 should not be an issue. Does it freeze when rendering a very basic scene? Does other GPU renderer freeze as well (e.g. some hardware issue)? Maybe running out of memory during cache pre-population?
