I need some help clocking my E8400 up to 4ghz.
Currently:
3.6ghz (9x400)
vcore: 1.288v
4 x 1GB ram @ 400mhz (this is 1066 ram)
NB voltage: 1.4v
ASUS p5q delux
it's stable at those settings, and my temps in crysis warhead hover around 60. Running prime95, it goes up to around 67-68C.
However, when i try raising it to 4.0ghz (9x444) vcore:1.33, my games will crash within 5-10 minutes. I've tried raising vcore, but am afriad to raise it anymore because my temps go up to about 70C in prime95 and around 63 in crysiswarhead. Is this safe? I'm using a zalman9700. Do you think i shud try reapplying thermal paste? because 70C in prime95 @4ghz seems a bit high for an aftermarket heatsink. I have exceptional airflow in my case, with 1 front intake, 1 back exhaust, 2 top exhuast, and 1 side intake.
Anyways, my main question is, what should i be changing to get it stable at 4ghz? Do i need to raise my northbridge voltages? I raised it up to 1.4v for NB because I used to get BSOD with 4 sticks of ram, but now i dont get those anymore. Would it mainly just be raising my vcore? What'r considered reasonable voltages for 4ghz and temps?
Also, is 9x444 much different from 533x7.5? because i know at 533x7.5 im running my RAM at max speed.
oh, and temps monitored using ReaTemp. Idle is around 43C
Thanks
