HI devious, try lower clocks, same temps will not cause throttle. Vcore is dipping more than .1v, this can trigger TM2 throttle, once EIST is turned off.

G0's clock well partially because they can handle more current(less leakage, it seems, in this case). This is the same for the "Super B" early edition Conroes.

I can get this same behavoir with G0 and B3 quads, mainly because of the high current draw. Never had it happen with a Core2Duo. Something seems to happen when the FSB is pushed up that causes the throttle, as the same is not true when current draw is high AND FSB are low, although I suppose that at stock current draw is going to be pretty low.

I know for sure that the limit on each board before this happens is different...currently p35 boards go higher before this happens, and hence my correlation wit hFSB, however my views on this issue are not ocmpletely accurate as I'm just a basement bencher/gamer, not a "IT professional" like the top guys.
