I have been having problems over clocking my system to 4ghz...it seems stable untill it bluescreens... I have a Socket 478 P4 3.4ghz Prescott(spu fan is the zalman CNPS9500 LED) 4x512mb kingston ddr400 memory ASUS P4P800E-Deluxe motherboard Promise sata2 RAID controller with 2x160 WD sata2 Striped ATI X850 256mb DDR3 XFI sound card al in a lian li case with a antec 420wt power supply it runs okay at 3.7ghz, but was wondering why it crapped out at 4ghz.. it was working at 4ghz last nite and then after I was done installing all the drivers it bluescreened. it is a fresh install of windows. also..tried to reinstall windows at 4ghz and it bluescreened again...at 3.7ghz it working fine right now... is there anyway I can get it at 4ghz? could it be possible it doesnt like to be at 4ghz?
