I had nothing but the installation of WMP9 open (idling) when I was ticking file association options -> it was idling 118W, and then, first the screen background applications froze with the mouse pointer still moving, so I looked over to the power meter and it suddenly jumped to 199-200W AC and then the mouse pointer eventually froze. It gets stuck at 199-200W AC until I reboot.

This is the problem nearly all of us are facing -> we need to collaborate and hunt this down, as to why and how to alleviate it. Unfortunately many users will have to carefully test this as well as me, or we'll make no progress. Remember those settings of mine are still around 100MHz below what I have max P95/Memtest 20hr stable.

Can this be the idle clock speed fluctuation I talked about much earlier (Achim caught it too)?

I think it must be. When you oc and at higher MHz your system freezes, the same reaction typically occurs -> jump in power consumption.

I'll now have to open a monitoring tool and just stare at it for hours to see the various speeds when it locks up.
Hmm mine does not freeze idling. It freezes above 2.5GHz-2.55GHz after ~3hrs. At 2.6GHz it freezes ~2hrs prime95.
I can use very low voltages for 2.5GHz, increasing em makes no difference (also tried the voltage settings you recommended in the DFI thread).
Due to that i do not have a vdroop or voltage fluctuations above ~0.016V.
Temps are allways below 50°.

Does a higher nb multi have an positive impact on the oc capability of the core's? I did not try it with a higher nb multi till now.
