Having some issues taking this oc past 4 ghz.. Any idea what I might be missing? I tried upping the voltages to 1.3-1.32 on the QPI/VCORE and the system shuts down on boot. Any more voltage would concern me. But the system hits 4.0 ghz with no overvolting at all and runs very stable. I just don't get why I'm having so much trouble going for even an extra .1 ghz. I'd like to hit at least 4.5 ghz but idk.. I must be missing something.. I tried running a x20 and x25 mutli @150-200 on the cpu, with a x8-x10 multi on the memory. Anyone hit 4.5-5 ghz on the i7 960 that might be able to give me an idea of what they did to reach it? Stayed with stock memory timings. 7-7-7-16 1t @1600. Thank you very much.
