My First Overclock - Need Some Help!

[graememk]

Hi!,

 

I've started to overclock my Q9550, so far i've got the fsb to 396MHz, so the cpu is running at 3365Mhz, but once i go to 400, the computer fails to post, and then will come up after a few tries saying there was a failed overclock, change settings etc,

 

I currently have everything else set to auto, voltages and ram timings,

 

coreTemp shows the cpu under load at 47,47,48,46. that has been running constantly since saturday. with the folding at home gpu client, and 2 instances of ubuntu folding, in vmware.

 

Currently CPU-Z shows the memory timings as 5-7-7-20 i think and running at 528Mhz, and the core voltage of the CPU at 1.240V

 

when i was trying to go for 400 FSB i tried changing the ratio so the adjusted memory frequency was less than 1066 (533x2) but it still wouldnt boot. I can try that again just to make sure

 

Any suggestions?

 

How high of an overclock would be possible on my setup, Rig is in sig below?

You will need to up the voltages for the CPU. Possibly the PLL, the FSB Termination, and the NB.

 

You will need to pick up a copy of either OCCT or Prime95 to check for stability.

 

Start over and make small increases in the FSB (10-15MHz) then get into Windows, run the stability test, I usually run OCCT for about a half hour when I am in the process of overclocking and if it passes, you are good at those setting, if it fails, you will need to up the voltages in very small increments and then re-run the stability test.

 

Thats just a quick overview of overclocking basics, there should be a link in my sig to a guide good luck, any questions just ask me

yeah he is right

Just wondering what would you call "safe" temperatures? ie at what temp would you be happy with your computer running at

something like that

 

No but to be honest...I dont mind it if my Quad is around 60
