Hi all!
I recently purchased the following rig:
2 x NVIDIA RTX 3090
AMD Ryzen 9 3900XT
ASRock X570 Motherboard
Antec Signature 1300W Power Supply
Installed Nvidia driver 455.38, CUDA 11.1, PyTorch 1.7.1, on Ubuntu 20.04 and tried running deep learning benchmarks.
The problem is everything runs fine if I use either the first GPU, or the second GPU. But the moment when I run both of them, the PC just shuts off. I suspected power related issue but I installed Windows and ran all the GPU benchmarks but everything runs totally fine. Now I’m suspected some driver related issue. Did anyone else face something similar? Or is there something I can do to narrow down the issue? Thanks!
