Running OCCT at 4.0Ghz now.
Bumped the FSB up to 471. It loaded windows and start OCCT fine but would blue screen after a couple minutes. This was at 1.3v (1.26v in windows) so I bumped it up to 1.325 (1.28 in windows) and so far its stable. Temps don't seem to be significantly higher.
Hell, if its going to be this easy I'm pushing this baby as far as it'll go.
I may try using LLC though since the voltage is getting up there a bit.
The Intel spec for these things says 1.36v is the max, but that's still pretty high.
