I think 1600Watt is still cutting close on your system. These cards can go beyond 300W each. We had a similar instance and we had to upgrade the power supply. Ours was for 2 gpu system so it was easy to find a power supply at around 1000-1200 watt. There are systems natively supports two power supplies. If yours can, you may use 2 power supplies.

I would recommend trying to increase the system memory (and perhaps CPU) voltage slightly. The former step seems to have helped with our Ryzen workstation.

Hey all,

I am troubleshooting one of our new thread ripper based workstations which crashes when using all four GPU's with Relion. The machine is running a thread-ripper 2990x with 4x2080ti's and its powered by a 1500W power supply.

Anyone here run into something similar?

Initially I was under the impression that its a power-supply problem, but the machine seems quite stable when running gpu/cpu bechmarks together that saturate all the cores and gpu's at the same time.

To rule out memory, I also ran memtest86 on the machine.

Any ideas are appreciated?

Thanks!
