Need some help with overclocking my Q6600 G0 :)

Hey folks

I've had my PC for a while now, but I've only just decided that it's time to see how much more juice I can get from the components. My spec is as follows:

Intel Core 2 Quad Q6600 G0
Gigabyte P35-DS3P
4GB OCZ PC2-6400C4 Dual Channel Platinum Revision 2 XTC Series DDR2
PowerColor ATI HD 2900 Pro 512MB
Tuniq Tower 120

I used to overclock a long way back, but only bits and bobs, my PC components would always limit what I could do. I was hoping this time would be different after investing in slightly better quality gear (the motherboard isn't fantastic I know, but it's still fairly decent) but it seems I've hit a wall again. I have managed to get my CPU stable at 2.8 GHz (315FSB) but it won't go above 320FSB without my system not booting up. Dual BIOS just resets the timings back to stock and away I go again.

I've altered the vcore from 1.25 right the way up to 1.5 with no change in the way the system reacts to the new FSB. Anyone have any ideas what else I should try to get it over this wall?

Many thanks everyone.

Sounds like a FSB hole on the motherboard but i don't know how much that board suffers from them..

Have you tried going to something like 350FSB or higher? could lower the mutli and slacken the RAM timings to take them out of the equation, then you are purely testing the FSB of the board

on top of lowering the multi and ram timings, add abit of voltage on the NB(+0.1v maybe), 1.5 on vcore seems abit extreme for 2.8ghz

It isn't running with 1.5 on the vcore right now, I only upped it gradually from 1.25 through to 1.45 to see if it would get me over the wall. It's back at 1.25 now.

I'll try going higher, but I've just updated the BIOS as it was a bit out-of-date. We'll see if that helps matters at all.

Forgot to add, I put extra volts on the chipset too, that didn't help.

Well, I updated the BIOS to the latest release (F11) and it hasn't made any difference to the overclock. Any suggestions?

Thanks

Set the multi to 8 and the fsb to 375

Thanks qwerty321, I'll try that tonight when I get home

Make sure you ram is running at the right voltage and then set it to something like 5-5-5-15. Also ensure the strap is set to 333. TBH, i would go straight for 400*8 @ 1.4Vcore.
