I have experience running 130,000 RX470/570/480/580... if you're doing heavy workloads, those things full machine crash if you breathe on them wrong. That said, when they do run, they run extremely well.
There is 1000 reasons why your one GPU could have crashed, what does it say in the logs before it crashed?
FWIW crashing a machine because of your GPU driver is pretty insane. Why would you want to use a stack like this?
