Re: 790i bios
That would be me.
I think you should stay with the 790i Ultra BIOS that's been flashed to your 790i FTW..The Ultra BIOS is more stable and overclockable, and that's what many hard-core overclockers have done back in the day.
If you want to flash it back to an FTW BIOS, that would require force-flashing it so that you don't get the error when trying to flash back..We can try to do that, but it's been so long I probably forgot how, ha ha.
My advice = Stick with the Ultra BIOS on your FTW board as long as it works OK.
