Hey guys. I've got 10 total rigs up and running and am starting to have some issues with the 6th one I built. All have 7 gpus. I noticed a few day ago that one of my rigs was performing terribly. I got a close look and my previously 30 mhs on my rx 580 Samsung 8gb msu gaming x had gone down to between 18-20. Almost as if the flash had decided to rewind itself. I tried ref lashing and got the usual errors. "already contains this flash and sub system ids don't match up". I also noticed something really peculiar.. Only the first two long pcie plugged in gpus are still performing at their peak levels. What in the world happened and how can I fix it? Btw the rig is in a super cold space with plenty of ventilation. I have not updated bios and that's all I can think to do at this point. Please advise.
