Stable OC on Games but not in CUDA/OpenCL applications

[ferrazrafael]

Hello,

I'm overclocking an Geforce GTX 960m 4gb GDDR5 on my laptop using MSI Afterburner. I can use it all day to run games with +135mhz OC on the gpu. But if I use Adobe Premiere Pro or other applications that are CUDA/OpenCL accelerated, randomly I get BSODs. This is weird because all games run fine with OC and all stress testing software that I tested showed no problem. And this crashes are not always when the gpu is in full load, in Premiere is more common when I'm editing than when I'm exporting video. So sometimes the GPU isn't even on OC clock, when those crashes happen.

This could be some Afterburner problem? Interfering with the nvidia drivers and the applications? Or CUDA/OpenCL apps are just more sensitive to OC instability than games?

When I dont use OC this random crashes goes away.

ps: Im using the latest drivers and bios and temps are ok system wise.

That would be my best guess.
For comparison i would use GFXbench vs. Compubench from the same manufacturer https://kishonti.net/

I tested with CompuBench and got interesting results. BSODs only showed up when the benchmark has ended not while running it. And they just happened using CUDA and MSI Afterburner. When I use OpenCL it didnt presented any instability. And using nvidiainspector to OC I could benchmark using CUDA or OpenCL without problems.

Even using MSI Afterburner without overclocking and running CompuBench with CUDA gave me BSODs.

Im starting to think this is a CUDA driver + MSI AB problem, not OC problem.

You guys think I should report it to nvidia or MSI AB?

Report it to both parties

Your videocard is abnormal, sorry. But it's 6 years old. If you get still any issue at STOCK SPEEDS (non-OC), you try DDU (Display Driver Uninstaller) but you should choose SAFE mode before run DDU while PC booting.

If you can't solve issue, you need to buy a new videocard for your laptop or a new laptop, sorry.

My EVGA GeForce GTX 980 Ti SC+ doesn't have any issue nor BSoD despite 5 years old (since june 20th, 2016).

I dont get any issues with stock speeds or using OC with opencl, opengl, or directx, just with cuda.

But thank you all for your assistance, I will report it to nvidia/msi so they can fix it in the future.
