Hi jsfoo8, I FINALLY GOT IT!
I flashed the BIOS again with some rom found in a forum, and now its working really nice. What was surprising to me was that ive got more mh/s with core clock @ 1250 and mem clock @ 2150. After doing that i was @30 mh/s, but only using claymore miner instead of the default ethos miner. So now ive got my 6 gpus doing in total 178 mh/s. Your article helped A LOT!
Hope u keep writing m8.
Best regards!
eddies can you please post a link to the rom you found in forum? i am having big issues trying to understand how to flash and mod BIOS for a Rx580. I am only getting 25 mH/s now on Ethosminer. Or if OP can please post a youtube video it would help tremendously.
