Hi guys, My motherboard seems to require an unusually high QPI/Vtt to reach 191, in fact it needs 1.450V just for 191*21, tried lowering memory and multipler but it's just unstable whenever I lower the QPI/VTT at 191, and any higher it just bluescreens even with 1.450V QPI/VTT.

What other settings can I raise to help increase BCLK or have I just got a crap board?
