Why CPUz ignores my overclock?

post #1 of 32
Thread Starter 
Hi Im really frustrated as I have spent ages following other peoples guides for over clocking my Q6600 on my Gigabyte P965-ds3

Here are my specs:
4GB PC5300 (333 mhz)
Intel Q6600 GO
Gigabyte DS3 P965 Rev 2

I have tried changing the CPU host freq to 333 which I think is 3Ghz. I have disabled the CIA2,C1E,EIST,VM,CPUID, no-execute memory protect

I have changed the system memory multiplier to 2.00
I have tried changing:
CAS Latency to 5
RAs to cas - 5
Ras precharge - 5
Tras - 15

Vcore is set to 1.325.. but I have tried it at 1.4 and 1.5

still nothing..? CPUZ still says my bus speed is 266mhz?? And the Core speed is still a standard 2400mhz x9.0 multiplier?

What am I dont wrong??

Welcome to OCN and fill in your system specs.

Did you remember to save the settings in BIOS? (Usually hit the F10 key.)

Screen shot of CPU-Z.

Make sure you're saving your BIOS and it's not popping up saying "Unstable settings restoring BIOS" before you boot up every time.

disable your speed step. It throttles back your PC while it is recognized as idle. You can test your overclocks still, just stress test it with orthos or prime95 and you will see CPUZ show your true settings.

I dont think you are giving your northbridge enough voltage for your FSB OC. add voltage to the NB aka G(MCH) in the Gigabyte bios. Try +0.2v.

The Gigabyte boasrd probably reverts to fail safe settings... If that doesnt work, try clearing bios. look in the manual, but you should just need to put a jumper on the pins or make contact between them with the tip of a screwdriver. no jumper by default.


[ctrl+F1] from the main bios menu will enable you to adjust memory timings within the M.I.T. section.
