Installed Nvidia driver 460, CUDA 11.1


no, just CUDA 11.1.
I was told thig might still be PSU issue.
even though the stress test with 100% utilization for both 2GPUs passes correctly, when running the pytorch training the GPUs+CPU might have big power spikes which the PSU cant handle (1500Wat, rated ‘80 PLUS Silver’).
I got the recommendation to get a PSU with ‘80 platinum’ or ‘80 titanium’ rating
what do you think?
