I removed the BIOS mod on my RX480, installed AMD drivers 19.4.3 and applied the strap. But I can't get more than 13MH/s out of it. Miner shows it applies the strap just fine but no results. With modified BIOS card runs 30MH/s with blockchain driver. Am I missing something to get back to the 30MH/s without a bios mod?
Be sure to apply compute mode : -y 1
Adding compute mode didn't resolve the issue.
Update: Compute mode did solve it. I failed to run it as administrator and then reboot. Thanks for the tip!
Update 2: Well that solved the 13MH/s problem but the temp is out of control now. I dropped the strap to 4 with 100% fan and it's still heating up to 70C in under 5 mins. Not sure what I might be missing now.
