They run just fine at 220MHz by the way, with substantially better 
performance and the chip still only gets warm to the touch. 

Mine is currently clocked at 200MHz, as I thought that 5.5 was an odd bus 
multiplyer, but all the benchmarks (and RC5 keyrates) were better at 220. 

I tried 240MHz, but it wouldn't boot. Anyone any idea why? 

If you want some of the little resistors to play around with clock speeds 
with I have 49 spare of each sort.
