I switched to wattool because the hex was a bit to much for me since I have cards that run at 850mv, 910mv, 915 ETC.
i do believe there is a tool for linux but I would have to search the forum for it, It's the same tool smos is using.
do u know where i can find how to edit the mV to 930 in hex or even if u can do it for me if i give u the bios and i can pay for that if needed to
