Sort of.
It does not just drop to 20x, that is the beginning. Push it harder and it drops to 18x.
Meh, regardless I need a better board, everyone tells me my vcore is too high for a D0. If I do not push it that high it does not boot. Either my drop/droop is really bad, or what I don't know.
Going to list my mobo on Ebay tomorrow since the i7 is torn apart anyway

And just get me a big boy board
I am not compalinign about my board, I am not even sure that it REALLY is throttling, but software seems to think so.
For instance
http://hwbot.org/listResults.do?user...plicationId=14
was running 21x for 4.5 Gigajoules i mean massive hurt. err megahertz

but I hit print screen too early and CPUz did not have a chance to up it 21x yet.
I up it to 220 Bclcok it drops to 18x under load.
