Q9550 oc help first time overclock

If I remember correctly, it will not be easy to hit 3.8 with that motherboard, you're going to need a pretty high front side bus speed.

Start by dropping your multiplier down to 6 then get your front side bus stable by slowly increasing it, the CPU Vtermination voltage and the motherboard's northbridge voltage until you get it stable at the desired front side bus speed.

The CPU should have no problem getting 4.0Ghz so maybe you should aim for 471 Mhz on the front side bus. Once that's stable, raise the multi back up and increase the CPU voltage until it's stable.

This is what I did to get 4.3Ghz on my Q9550. 24/7 stable.

It took me 1.28125Volts to be 24/7 stable at 4.0 Ghz

Also, free bump for filling out your system specs before first post.

Raise your voltage. I'd try 1.3 at first and go up if required. Do not go over high 1.3s, anything under is perfectly safe but >1.3 you might start getting hot temperatures.

One of the problems that I see is your memory voltage is a little low.

OCZ normally runs at 2.1v unless you have the ULV kits.

Run the memory within spec so that you can pin point the issue.

I went on the ocz`s website Ifound this:

OCZ EVP (Extended Voltage Protection) is a feature that allows performance enthusiasts to use a VDIMM of 1.9V without invalidating their OCZ Lifetime Warranty.

Is that mean I can`t go above 1.9 or if i go eg. 2.0 V will it fry my memory?

Set your memory voltage to 1.9V.

Maybe take a look at your memory there should be specs written on it like latency,voltage,etc.. to be sure.

I see your memory is DDR2 at 800MHz,but you should be able to overclock it to 900MHz or more.

Until 823Mhz is fine with 5-5-5-18 timing 1.9V ,fsb 411 @3.5ghz 1.3V but as soon i start to raise the fsb even just a little bit it doesn`t boot.

Is it possible that the memory holding me back? Or do I use wrong timing?

Set the timings to 6-6-6-18 & try again.

Thanks for the reply guys.
I think i stay with the 3.4ghz until i change my mobo and memory.
