Hi, I don’t know if you saw my post earlier? #6451

How are you modding the bios? With OverDriveNTool, afterburner or hard coding with a bios change?

Thanks.

Just saw your post, I get it that you were using stock bios cards with Claymore and applying straps and rxboost to increase the hashrate. AFAIK Phoenix miner currently does not support "straps" for RX580 (all polaris) cards, so you'll have to bios mod these cards manually (using 1 click bios mods or any other tools) and then try using the overdriventool settings and then you'll get similar hash rates on RX580s.
