Try to increase your VTT 1.35 or higher (something reasonable of course). One CPU I have is stable at Vcore/Vtt = 1.30/1.35 and I'm pretty sure I can optimize that to lower values. Another is only stable at 1.31/1.39 etc. They also run at 3.8Ghz (211x18) at < 1.3V Vcore and < 1.35 Vtt, so I guess that's the "sweetspot". You shouldn't have much difficulty setting them up for 4.0 Ghz, albeit with (much) higher voltages. Are you using the Sabertooth or the Classified? My EVGA board won't even POST, though in general I kinda hate EVGA boards for overclocking.

I use the sabertooth for now. The Sr-2 has no problem woth that CPU so I suppose the other EVGA boards should be able to run it.

I let the VTT at auto, just to see what the board was doing. So I suppose I'll have to look at setting it manually. So Vcore 1.30 ish and Vtt 1.35-1.39. did you leave everything else at auto ?

I set the CPU PLL: 1.80 - 1.88 Volts, IOH/ICH: 1.20, VDIMM: 1.65 (or 1.64/1.66 depending on the board) as my baseline and it seems to work for all of them. Good luck man, show us lots of pictures!

yeh turns out some vtt was the secret, I am now stable a 3.975 But I have to push about 1.34 vcore and 1.39 vtt

ah, you bastards! *shakes fist*
after readin this, now im looking at the SR-2 to keep up with the cool kids!

looking at.. financially I don't think i'll be able to.. >.>
