Specs:
Intel E8400
Asus Rampage Formula
CORSAIR XMS2 DHX 4GB DDR2 800
Visiontek Radeon 4870
Western Digital 640 GB
Samsung 22x DVD Drive
Cooler Master RC 690 Case
Corsair 750W PSU
Xigmatek 1283 CPU Cooler
5x Scythe SFF21F 120mm fans, 1x CM690 120mm default fan
I can overclock the E8400 to 3.6 GHz on stock voltage without a problem.
The problem is when I try to set the voltage above the stock voltage (that is, more than about 1.2v). When I do this, the monitor says it can't detect any input signals and remains black. The computer turns on, but doesn't load into Vista. I suspect it shows a screen that says the "overclock failed", which is what I get when try to overclock past 410 MHz. I tried using two LCD monitors and tried both VGA and DVI inputs.
So what's wrong? The mobo, the CPU, or the GPU?
Also, if I try to overclock past 400 MHz (3.6 GHz), I get a error message from Windows Boot Manager while booting up: winload.exe can't be found.
