Topic: Does GPU mix and match cause the system to crash? (Read 550 times)
Make sure you using the same drivers on each card and the same stick bios. Try getting them working at a basic level before you try optomize the speed. Make sure the clock speeds on the gpus are the same. To me it makes sense and to me I would expect difference soeeds to cause issues. Try and see.
Problem was with the motherboard. I swapped the cards to another machine when my extenders came in and everything is chugging along.
Flashed MB bios to latest, no dice
Flashed card bios back to stock, no dice
Flashed card bios back to 1500 timings, gpu underclock, mem overclock, no dice
dunno, guess i'll mine on 1 and wait for my risers to get here tomorrow then try to run them along side the other node that has my RX580s. If it still doesn't work then, guess I'll have to split the cards up.
No it shouldnt cause it to be unstable. Even with older GPUs.
You can even mix Nvidia and AMD and it works. Your issue is somewhere lse.

I flashed the firmware from the RX570 nitro to the RX570 pulse (my pulse now thinks it's a nitro). It mined a bit longer -- went from 15-30 seconds to 2-3 minutes (submitting multiple shares before crashing).
I then tried running multiple miner instances (1 instance for each card). Same, 2-3 minutes then crash.
Roll back to stock and see what happens

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.
