The ones I have worked with get really power hungry after 4.6ghz. 4.8 has generally required 1.475 - 1.5V+ and rises to a ridiculous level past 4.9-5ghz requiring 1.55+. My best was a clean run at 5.1 at close to 1.596v Which was done for giggles only.
Best trade off with vishera so far to keep voltage / power consumption low and a reasonable overclock usually sits around 4.6ghz.
I ran Prime 95 for about an hour and Core 7 & 8 had errors. I find this interesting because even at stock speed and voltage I get errors.
Anyhow believe it because I am running at 4.80 GHz at 1.385v via bios (Bios always sets it a little higher) Rock Stable. When I can play L4D2, Skyrim, Metro 2033, Rage etc. none stop for a few hours and no crash, to me that is rock stable.
I may up the vCore another 0.010v to 1.395v and test the Intel Burn Test because this is the only test IMO that acually makes my temps go up. Not even Prime95 does this.

Just upped the voltage. Now it's sitting at 1.4v. Will run IBT Very High for 10 times. Should equate to around an hour.
