Q6600 Overclock settings

a lot will depend on your motherboard and cooler but.

this is a very basic explanation of overclocking

its basic maths. your Q6600 is rated at 1066mhz. you always divide this number by 4 so 1066/4= 266, this is your fsb. (or cpu frequency)
then your processor (cpu) has a multiplier of 9 (it may say cpu clock or ratio)
so 266 x 9 = 2394mhz or 2.4GHz

unlink your ram, so it stays at stock speeds, you can overclock the ram later, or set it to 1:1 ram/fsb ratio

can you raise the fsb?

try rising it to 280
boot into windows
download realtemp and coretemp (google them)
install and run them
then download Intel Burn Test (ibt) and run it.
have a look in task manager and notice how much free ram is listed.

in ibt set threads to 4 (for 4 cores) and then click on custom ram and enter an amount just below the free amount.
eg. i have 2520mb free ram. so i enter 2500 into the custom ram.
run the test for 5 passes. for now, and then at final speed you want, run for 50 passes,
(this is debateable, but a stable overclock is usually classed as 20-50 runs of IBT, but its personal preference)
or do an overnight run of prime95

keep an eye on temps (do not let it go over 80.c) or in realtemp, notice the distance to tjmax, never let it go less than 20

if test runs fine, go back into bios, and change frequency (fsb) to 300 and repeat the tests.
keep doing this in 20mhz steps until windows will not boot. then just go back a step (remove 20 from the fsb) to the last stable frequency,
OR
just raise the cpu voltage a couple of levels. it should now boot.
its a balancing act, higher voltages will get you higher fsb, but it will also give you higher temps.
the Q6600 is fine upto 1.5v
oh and i would remove the 2x1gb ram sticks for nowm its easier to get 2 sticks stable than 4.

edit, just realised this is in 8 packs forum, sorry

Thanks for the above mate.

I can change voltages all ok, if I tweak anything else the pc just won't boot?

If it helps when I go to save to bios the of switches off, the red led on the board flashes really quick for about 1-2 minutes. The board then starts up again with standard settings.

I have tried with the 1gb sticks out and even swapped in the 1gb and removed the 2gb, no different.

Changed the battery on the board with no luck, sounds to me like the motherboard could be failing??

The PSU is a 580w hyper, which has served me very well over the years.
