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!
