Yes I modded the BIOS. This is my current configuration https://drive.google.com/file/d/0B8J54NDM1ImqODc5UUlkUDVwNEk/view?usp=sharing


I copied the 1500Mhz timing to the 1625,1750 and 2000 timing. That improved the etherium mining from 21 to 24.7MH. I tried to clock the memories in GPU Tweak 2 but that didnt go well hashrate down to 20MH again. Do I need to raise TDP/TDC? Are they to low?
