Help Overclocking Quad9450-mushkin Ddr3 1600mhz 1.8-1.9

[depecheboy]

HI ..

After yesteday my pc works fine with the OC.. i have a quad9450 and i OC it at 3.2ghz. But then i read that this quad can increase at 3.5ghz without problem.

So i test with different values in many components. like memories, vcore, etc...

My problem is that my pc dont recognized anything now.. i change the values many times but when i execute cpu-z its only recognized the default values of the quad 9450: 2.66mhz.... i dont know what to do,,i try with many combinations but i cant increase again all the values of my quad 9450 and my memories.

this is my pc:

 

-Core2quad 9450

-Motherboard: Gigabyte EP45T-EXTREME

-DDr3 Mushkin 996629 2x2gb 1.8-1.9v

-AtiRadeon 4870 512mb

-Cooler: Coolermaster Hyper 212

-Power supply: NeoPower 650w Blue

-Case: Nine Hundred Antec

For 3.6ghz this is what I have my voltages at.

 

Cpu voltage 1.26 For 3.8 I need 1.34

NB voltage is stock at 1.33

CPU Vid voltage is 1.26

 

I set your ram at the stock settings and voltages for now.

 

Turn off speedstep, C1E, and all that other junk.

I found that taking the PCI express frequency off auto and setting it to 100 helped stability while overclocking my gigabyte x48t-dq6 board..
