Quyen,

I will try swapping out the memory and power supply and see if that changes anything.

Thanks!

Hi Abhiram,
We had a workstation behaving similarly couple years ago.
It turned to be a bad power supply.
Like yours, it worked fine most of the time, but shut down when running a certain program under full load.
First we changed the motherboard, swapped video cards, RAMs, and finally the power supply.
We have used power supplies from a few different brands and have been happy with Corsair.

Cheers,
Quyen

Clara, 

In my case, the system just powers off. So I am quite puzzled. 

I hooked up a watt-meter to the machine to see if I am stressing the power supply, but it doesn’t look like it. 

I am yet to check if there is a new bios for the board( Gigabyte X399 Aorus Extreme) 

Anything specific to PCie settings that I should be watching out for?

Thanks!

Abhiram

You mean the operation system crashes or RELION is crashing? 
Have you checked if the motherboard BIOS has a new version? Pay attention to the memory and PCIe settings especially. Good luck!

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!
