I have reached 33MH/s on it - if I go for low power, then 31 - 32.

@wolf0
Do you have an idea for the best efficient Bios for RX 480 Red Devil also with Samsung Memory?
I've flashed the BIOS from Boysie (low energy) yesterday, but power is too high i think, 150W measured @27/350 ETH+DCR.
I think, the best way in first step is to reflash the BIOS with the original BIOS Form Powercolor.
What do you thing?

Sorry for my bad english.

[mrbugera2]

my power is high too

If you get 33 MH on it, then most likely you have memory errors at background. Although miner will report high rates, on pool side results will be unexpected and less.

I recommend that you use power save bioses (one from Jukebox for samsung chips was good for me) to have good hashrate/watt performance and longer gpu life.

Search for ubermix timings  3.1 and mod your bios with Polaris Bios Editor (save your original bios first).  Set your core clock + memory clock + undervolt your card in the claymore miner batch file.
You can get about 30 mh/s with this timings and the right config in your batch.
