I am trying to oc a C2D 4300 on Asus P5B Plus Vista edition with 2 x 1GB Kingston DDR-2 800 RAM using the stock heat sink. With all other BIOS settings as default values, The max. CPU frequency I can change without system hang at bootup is 220 (which is essentially 1.98 GHz). The temp display at BIOS is pretty normal - 41C (CPU) and 42C (M/B). I have tried to fix the PCIE at 100 and PCI to 33, but it didn't help. Anyone can shed some light on this? coz I would expect at least I can oc a 4300 to run at 2.5-2.8 Ghz. Thanks.
