OMG I’m stuck at 612-613FSB by that damn board!!!  Limit is exactly the same on Air cooling than under the Grosse Bertha.

I’m trying a real gem of chip right now. Boots and runs Spi32M at 611FSBx9.5 @1.75v

I need a better board.  6GHz Spi1M under cascade is doable IMHO…

Playing with my cascade this afternoon…

I can’t get that chip over 612FSB; and stability is extremely difficult to find over lets say 595FSB. Dunno what’s the matter actually, CPU, mem controler?… BTW 5.7GHz Spi32M and 5.8GHz Spi1M are doable… 

CPU socket temp was rock stable at about -112C during 32M anytimes I ran one. (count about 11 to 12C less for an estimate of chilly1 style evap temp; i.e -123C to -124C here)
