Q6600 overclock unstable.

NeoVo · 21 Mar 2009 at 22:09

First off, im a complete noob to overclocking, but read all guides and stuff on the forum.

System specs are in signiture.
I managed to achieve 2.587ghz, which i know is far less than the capabilities of this chip. I tried raising the fsb speed more but i had an error on the boot screen, lowering the fsb cured this.

Iv tried a variation of games, since the overclock and depsite noticing a mild performance increases, the games close within 2 minutes due to a few problems.

Iv uploaded a screenprint of coretemp + cpu-z. Il take some pics now of the bios.

Thanks in advance.

I have Corsair 4GB DDR2 XMS2 PC2-6400C5 which runs at timings 5-5-5-18.

My vcore in bios is set to 1.300V but on cpu-z it reflects as 1.28, is that normal?

I have a zalman 9500 LED cooler, iv ran prime, and temperatures go to 50 after about an hour.

Is the memory running far past its advertised speed, or have you unlinked it?

I have them linked, could that be why?

What settings should i use for say.. a 2.7ghz overclock?

Set up the memory divider so that on a 2.7 overclock the memory won't be over 800 mhz.

Do you know how to do that?

as silly as it sounds.. no, any walkthroughs/advice?

on Bios menus - Extreme Tweaker/fsb and memory tweaker.

Memory options on there.

so, on there i should put the memory timings of the RAM in?

Ok, i managed to get the q6600 to 3.0ghz using the settings that 'siumatfung' recommended though still experienced crashes and instability. Now running at stock speeds until i buy a new motherboard.

Was planning on going down the i7 route, but not with current prices.

Can anyone recommend a good overclocking 775 board for my q6600?
(I personally prefer asus or gigabyte).
