Nehalem 101 part1 - 1366 and X58

[G.Foyle]

I can hit 385x MHz, but only 20 mins Prime stable before the PC resets. I tried up to 1.4V Vcore and VTT + 0.2 V max.

It takes much more voltage to get Nehalems to 4 GHz than with Penryns. I could hit 4GHz only with 1.45V on the 965 and 1.475 on the 920. Seems like 920 can be maxed on air, at around 4100 MHz and 1.5 V.
