For my 4.5GHz (21 x 215) OC I used these settings;

vcore: 1.44375v
CPU PLL: 1.86v
IOH: 1.2v
ICH: 1.2v
QPI/Vtt: 1.35v

Disable all Speedstep, C1E, Tech Virtulization, C-State Tech, CPU Speed spectrum and PCI-E Speed Spectrum settings.

They are the settings I had to use to get my 930 to 4.5GHz stable. So try some settings around those and play around until you can find the sweet spot. I found once I get over 4.4GHz, I need exponential increases in vcore to get the CPU stable. So just play around until until you get it stable and good luck!

Bump that QPI/VTT voltage up a lot! This is the voltage for your memory and L3 and is constantly being stressed, especially with an overclock of 4.0Ghz. Put it at 1.3-1.32 volts and see how this works for you. Honestly I'm surprised you were able to get 4.0Ghz stable with it that low.
