My settings so far:
CPU 9.5x
FSB 443
FSB STRAP 266
RAM 1111 or 554Mhz in CPUZ

vCPU 1.35 BIOS, 1.316 CPUZ
vPLL 1.52 -- TRY 1.54
VTT AUTO -- NEVER AUTO !! Try 1.24
vDIMM 1.9
vNB 1.26
Give her some more Vcore mate, set eg 1.375 which will be 1.33 under CPU-Z, those are really low volts you are setting for 4.2Ghz ops... if this was an EO E8500, I would say okay but not for a CO model...
