My rig has 2 Gigabyte RX570s and 4 Gigabyte RX580s. I have read everything I can and watched a ton of videos. Modded the BIOS as per instructions, using the latest blockchain driver and patcher. My best card hashes at 27 worst at 25. OC with Afterburner does mostly nothing except make hashing get a little worse. I am using Win 10 and do not want to use Linux or a command line OS. By all accounts, I’m supposed to be hashing at 29 to 36. BTW, there are some instructions that say to change BIOS from gaming to computing. I don’t see this option anywhere. If you’ve got a minute, I’d appreciate hearing your tips for better hash rates.
