Yes thats my card, already checked for BIOS in their database, and they haven't gotten my card.
They have https://www.techpowerup.com/vgabios/188078/powercolor-rx470-4096-161005
But thats with different core clock

Getting 28.8 Mh/s atm, with 1050/2000/900 mV

Anything over 2000, and i'm loosing hashrate. But my core/memory is modded in the bios.
Thats why i want to try to mod a original BIOS and see if i can get over 2000....
