Also you may need to take your PSU into consideration.
Also you may need to take your PSU into consideration.
this is a very basic explanation of overclocking
its basic maths. your Q8200 is rated at 1333mhz. you always divide this number by 4 so 1333/4= 333, this is your cpu fsb. (or cpu frequency)
then your processor (cpu) has a multiplier (or may say cpu ratio) of 7
so 333 x 7= 2331mhz or 2.3GHz your stock speed.
boot into bios, disable speedstep and C1e and any other energy saving features.
unlink your ram, this means leve it to run at its stock speed, eg. 667, 800mhz etc...
can you raise the fsb? yours is now 333. try rising it to 350
boot into windows
download realtemp and coretemp (google them) also download cpu-z, this will give you all the info you need, eg. cpu speed, cpu voltage etc...
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.
keep an eye on temps (do not let it go over 70.c)
if test runs fine, go back into bios, and change frequency (fsb) to 370 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 Q8200 is safe upto 1.36v
at final overclock speed, do an Intel burn test for at least 10 passes or do an overnight run of prime95, large fft's test, to test for stability.
the temps will be high, but don't forget that this is extreme, day to day temps will be around 20.C lower.
the trick is to do this step by step,
get the cpu maxed before increasing the ram speed
also if going down this route, please get a proper cpu cooler.
as temps will limit how high you can overclock.
if you search Q8200 overclocking on this site or google, you will find loads of settings to try
