Whats the best way to overclock the Q6700 on a Asus P5E board and 8gb ddr2 ram at 333Mhz and an evo 212 cooler master aftermarket cooler ?
Thanks :)

The max safe voltage for the Q6700 is 1.450 Volts. Do not go to Intel's max of 1.500 Volts.

For FSB type of overclocking you should start out with the lowest memory ratio; 1:8 I think, lower if possible. Then do the OC and see where the RAM frequency ends up. Like I mentioned, a slight underclock of the RAM frequency is perfectly fine.

Perform OC in gradual increments, raising the CPU voltage by 0.5 Volt increments, and then run the computer for a while. Stress test. Check temps.

Overclocking is a slow process and takes several days for fine tuning. Do not rush.

Max temps were at 67 degrees celsius during the stress test but thats before the fan kicked in a bit more and quickly brought them down to a stable 60 degrees so I'm good for everyday use. I could overclock it a bit more since I am at only 4.5 volts but im not sure im going to be able to handle the temps without the fan going too loud. Just a question, should the ram be at +0.25 or not?

Leave the RAM at whatever frequency you get when you OC the CPU by raising the Front Side Bus. Only the "K" suffix CPUs have an unlocked multiplier where just the CPU will get ocerclocked. The other method (like you did) for CPUs where you have to change the FSB will raise everything along with it, including the RAM.

On my X58 computer I overclocked the way you just did your Q6700, by raising the FSB. I ended up with a slight underclock on the RAM which is perfectly OK. Further tweaking would have shot up my RAM frequency too high and made it unstable.

Run your computer at the present OC settings and keep an eye on the temps. The temps you posted are very acceptable.

I did not understand what you meant by "4.5 volts" Please check.

I meant raising the core voltage of the CPU. Apparently I can go up as high as 5 volts if I really needed to because its a 65nm chip. When I left it on auto and did the stress test at 3GHz it worked okay but when I OC to 3.3GHz two cores (workers in p95) would stop working. So at first I brought it up to 4volts but one core would still stop working. So I brought it up to 4.5 volts and the stress test ran smoothly for a couple hours (I used prime95).

So basically if I really wanted to I could go up to 5 volts and set the FSB higher in order to get a higher clock speed but the heat could be too high.

Also another question.
I have my FSB at around 330 I think, so my ram also runs at that speed. I was wondering if I could lower the multiplier to 1:8 and instead increase the FSB higher to also get a faster RAM speed while getting the same OC (my ram is rated at around 670 or something and the FSB can go up to 1333 if I remember correctly)

I have an X38 chipset
