Anyone know Intels maximum vcore, and vtt for these chips?

1.4v is Vabsolute, 1.52v is max SVID just like SB. Max VTT and VCCSA is 1.4v. Those are absolute ratings listed, but intel lowered max vcore from 1.52v for SB to 1.4v for SBe. IMo don't go over 1.7v, i wouldn't even go over 1.6v at least above ambient. They are all in the datasheet, check em out under electrical specifications.

don't want to bash the party here, but looking at intel's datasheet i found the following figures for max voltage specs and absolute max ratings (red):

VCC 1.35V 1.4V
VCCPLL 1.881V 2.0V
VCCD 1.575V (DDR3) 1.85V
VTT 1.095V 1.4V
VSA 1.2V 1.4V

remember this is intel spec. we are at xtremesystems here, so most won't even care ...

... but you asked

Yes, and also note that the absolute max voltages are based upon power draw at stock processor frequency only. Increase frequency and you breach the power band the specifications have been listed for.
