I think so

Hmm...cold bug is 315 mhz htt @ -42c....and the cpu wont be hotter at overclocking. look at this screen:



I think that if there will be constanctly -40c it should possible to do some more mhz....dice or little ln2 is the key.
Because I can not boot with more than 1.904 volts...

But 12x288 mhz at boot
Stepping is LDBHE 0540 SPMW --> SPMW as the FX-stepping by the way.
