Problems overclocking 3960X

[idata]

Asus RIVE, Corsair Dominator 1600, Gainward GTX690 + good water cooling.

Just reinstalled my Windows 7 64bit Professional on clean disk Corsair Force GT 480GB.

Used Gamers OC in BIOS.

4.5GHz.

I have to up my VCORE to 1.44v just to get passed login screen. To get Windows to load completely I need 1.45v. To be able to run 3DMark11 1.47v.

I have also uped my VTT at the same time, and it's now at 1.3v

This is obviously way to high.

So what is the reason for this? Do I have a "bad" processor? Is there any programs to test the CPU in the same way you do RAM?

Here's a link to my last 3DMark11 score: http://www.3dmark.com/3dm11/6047169 http://www.3dmark.com/3dm11/6047169

We would recommend running the Intel® Processor Diagnostic Tool to verify frequencies and features on the Processor. You can download this tool at:

Please bear in mind that when a processor is over-clocked the processor increases the core voltage at the cost of system stability, power consumption and heat dissipation. It may damage or shorten CPU life. Therefore, Intel does not provide any guidance or recommendation regarding over-clocking.
