his 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 (or cpu ratio)
so 266 x 9 = 2394mhz or 2.4GHz, your stock speed

unlink your ram, so it stays at stock speeds, you can overclock the ram later

can you raise the fsb? yours is now 266. (266 x 9 = 2394mb or 2.4ghz ) 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. (or prime95, then run small fft's,)
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
keep an eye on temps (do not let it go over 75.c)

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.
my B3 revision Q6600 needs 1.39v in the bios to get to 3.3ghz.
if yours is a G0 revision, you should be able to get this speed at a lower voltage


the trick is to do this step by step, and not go straight to eg. 400 (400 x 9= 3.6ghz), just take your time.

also for some reason using the x9 multi, i couldn't get past 3.0ghz
so i dropped it to a x8 multi and i got it to 3.3ghz easily.
get the cpu maxed before increasing the ram speed

or if you dont want to use IBT, then use prime95. or use both ;-)

edit. some motherboard settings here at bottom of page http://forums.tweaktown.com/gigabyte...ep45-ud3l.html

also found one of your old threads http://www.overclock.net/intel-cpus/...-2ghz-3-a.html
