Xello, 222 is hard line to step over.
Benny's word record on i7-920 ES (229+) is greatest result.
There is some kind of hardware bug in C0/C1 stepping, IMHO.

Guys, what is your max NB freq?
I have only 4200 Mhz SuperPi 32M stable on Vqpi = 1.555v and Vqpipll = 1.44v, cold water.
I see dinos22's SuperPi 32M i7-920 WR taken at 4400+ Mhz on SS.
Is extreme cooling significantly improves this freq or it is total processor-dependent?
