Hello. I've got 6 cards (1 RX 580, 1 RX 470 and 4 RX 570 cards). The setup works fine without Overclock and it is getting me 131mh/s for Ethereum. I'm using the Claymore eth v10.2 SimpleMining os (rx dag fix).
When I try to overclock the GPUs (I have tried even overclocking just one of the GPUs) via the website on simplemining I get this strange error on start up
BUG: soft lockup - CPU#0 stuck 22s
Then I have tried using MSI Afterburner, and Polaris Bios Editor editing 2 of the cards (one by one) I kept getting the same error
Then I couldnt even start the rig even when I Returned the normal bios, after few tries I finally got my rig back up with the same hash rate and no errors
So any clues, how to overclock my gpus to get maximum hash rate? Please help!!
