They work on my systems. Had to add a fan to the chipset heatsink though
to stabilize them. That chip runs too hot. Also saw a similar problem on
k7s5a's and we're testing the fan on the HS there at the moment.

Were the MP's the same clock rate as the XP's you had previously or did you
downgrade to a slower clock? Slowing down the chips makes the problem go 
away on k7s5a's. That was the first test we did.
