I switched to the 74 bios and I can honestly say ive had nothing but problems. I havent touched my system in close to a year settings wise and recently got a waterblock for my mb over summer and just felt like seeing if I could push it a little more past 4.2. Updated my bios and having a hell of a time getting stable at 4.2 now. I know im rusty and not a veteran or anything but I dont remember having to fight this hard to reach stability at 4.2. Whats the best bios concensus for a 920 D0 chip.
