I have just upgraded my x58 system with a costum watercooling loob. After doing that i can't OC my cpu (i7 950). It runs fine on stock speed, but when i try to do enything it only runs until i lock in to windows. On air i had i running 4 Ghz no problem. Now i just reeboots. Can enyone help me?

 

MOBO: GA-x58-usb3

CPU: i7 950

OLD CPU cooler: Artic cooling - freezer xtreme-

NEW CPU cooler: EK-Supremacy EVO - Acetal

Have you checked temperatures? Is the CPU overheating at all? You could have issues with your loop.

The temperature is fine. Its about 30-32 degrees C at idle and 40-42 at load. And when i try to OC it do not have time to heat up (the temp right after the reeboot is at 30-35 deftees C)

Any OC at all? Or just when you get up closer to 4GHz? What happens if you raise the BCLK up one from BIOS? From Windows using the buttons on the board? Easy Tune 6?

Too much socket pressure ? Sure the pump is running ?

Take off your waterblock and check the cpu contact.

 

If the cpu heatspreader footprint looks ok , then take of the cpu and check the general condition of the socket pins.

 

If everything looks ok , put everything back and make sure you dont tighten your waterblock too much.

 

Test again your o/c
