Petz, "Bert McComas showed that the only way to get the P4 out of half speed mode was to reboot" I think the effect has nothing to do with thermal throttling. The throttling is easy to monitor by looking at the PROCHOT# signal, instead of bold speculations. This pin is easy accessible from the back of mainboard. The effect of performance deterioration may have another, simpler explanation - it may be related to randomization of memory pages under Window's memory management, and for some reason the P4 does not like it much. The reboot forces a system to start with a fresh memory layout. The whole issue with P4 thermal throttling is largely overblown. This is a good protective feature, and I wish AMD to implement something similar, and as soon as possible. - Ali
