I have a system I just built with 1x RX 570 pulse 4GB and 1x RX 570 nitro 4gb. The system runs fine with just the pulse or nitro. If both are together it crashes (screen shows lines / hard crash). I've been playing with memclock and gpuclock settings for a few hours now thinking that was the problem. Until I realized it wasn't.
Why are they crashing? Is it the mining software that's the problem, drivers, or what? Is there a fix? I don't really want to build another system just for 1 gpu.
I'm running ubuntu 16.04 with AMDGPU-PRO-17.10
maybe
first off are you sure the cards are stock bios?
try smOS instead. it is linux based so if it works it is a driver issue on your linux setup
no, they aren't stock bios. I modified them to 1500, gpu underclock and mem overclock myself. (30.5Mh/s eth, 375Mh/s sc on the nitro, 27Mh/s eth, 375Mh/s sc on the pulse)
I can run either card fine by itself for hours. When they are together it crashes instantly (literally, 15-30 seconds after dag creation completes it dies).
I'm using the same setup for my gigabyte rx580s and it works fine. But, due to GPU shortages I just bought what was available instead of looking for matching cards.
