I wonder if I raise FSB, I set PLL, VTT, NB voltage is auto => the mobo will raise the their voltage or set the standard value? My mobo is P5Q, CPU Q8400. I set FSB to 460, Vcore 1.25, Vdimm 2.0, the remain is
auto. Test Prime 95 large test is OK for 6h, but I set FSB 470 Prime95 only fail only on Core 1 after 5 min, 18 min...time fail is random in 30 min test. How I must tuning? Thanks
