i watched some videos and made bios by myself  Undecided and with new amd driver (for cryptomining)
i cant get 28and more, please help me

i have 28 MHs Sad i think sapphire rx480 nitro + 8gb (SAMSUNG) must have more hashes Cheesy help guys to encrease Sad




and the power 115-120W

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.

I don't have a Red Devil, but I *do* know I've worked with customers' PowerColor cards, and their cooling sucked so bad that the GDDR5 was cooking, and wouldn't perform as well as cards with proper cooling. That said, Boysie doesn't know a VBIOS from a hole in the ground - and he certainly has no idea how to properly undervolt cards, such that it works on all OSs.

Hi Smiley

To be honest - I'm also using a modded VBIOS by Boysie as I don't have any experience about VBIOS modification or even proper undervolting.
For my 8GB PowerColor Radeon RX 480 Red Devil (Samsung memory) his lowpower BIOS seems at least to lift the hashrate to 29 MH/s while the temps seem to be okay.
I guess there would be more possible but for now it's okay for me as I'm mining just for fun using my gaming PC as I don't have much time for gaming right now.
However his other VBIOS for my cards seems to cause tons of mem-errors.

Any one still have Sapphire Rx480 8 GB Samsung Memory, Can share modified bios
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.

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.
