Eth received, Thank you. I enjoy bios modding on my cards however it has always been a pain with some memory types. For example on rx 470 4gb Hynix cards I can't get them to hash over 27Mh but all my rx 470 4gb samsung cards hash at 29-30MH.

Thank you for your help, but are you sure this one will work ? have you tested it before ? i didn't flash it yet, but i used similar mod yesterday and didn't work, alot of people saying it's can't be modified, just want to make sure that u tried it before ?

thanks

I have not tried it however there is no reason it shouldn't work. If I had the card in front of me I would keep going even if that ment I had to start digging into hex. However I had to put together a separate machine running 16.11.5 to flash some of my samsung memory cards then when put back into a system running 16.9.2 they worked perfectly.

Side note if none of them work your not out anything however if they work and you chose to send me a tip that would be cool.

Woohoo, Who said Micron is sucks Grin

, Finally it's worked hashing at 30.3XX, after few edits in bios and Wattool,

I have searched the forum here for help and even Google but it seems that there is no reliable/helpful advice with this card in particular.

If you want to attain stable 27 MH/s, do you know you can get it without flashing through Claymore miner's integrated functions?

Use -cclock and -mclock, check FAQ of Claymore miner for more information.
