f6 bios is awful I guess I should revert back to the previous.. I need lots of vcore for stability and all the benchmarks lock up.. On my xeon w3680 and the i7 980x... 5800mhz stable on the 6 core xeon using f4 bios.. Just tried f6 and an i7 980x es on ln2 and it was awful.. Hopefully it's the bios and not the chip.. It's the q3fe ..
