I need 1.92 set in the bios Big Lar up to 1066Mhz with the early PC8000PQ kit (my board still overvolts about 0.08 with 1406 bios, Vcore is lower now, I need to give about 0.0625 more to get same volts than with 1402 or earlier biosses...) Sure it's not Nb or CPU Voltage you need to up a bit..., also is Static Read control disabled ? Trfc 55 ?
