Whooeee, just finished downgrading my bios from A12 to A10 and then flashing the modded bios. Many thanks to the OP and other users posting updated file dir's etc. I did this primarily to disable hyperthreading, but now realize I have access to a whole suite of advanced options to potentially tweak. Can anyone point me to a discussion here or elsewhere that would serve as a good starting place for optimizing/tweaking an M17x R4 with a modded bios? I'm probably not an 'advanced' user, but this is not my first modding rodeo, I know how to take proper precautions and can follow instructions to the T. Primarily looking to get the most out of my gaming experience. Thx, and love the forum.
