Thes cpu is a core 2 quad and have 2,5 Ghz. my memory ram is 8GB 1333Mhz, how could overclock my Q8300 to 3GHz stable? Thanks for the help and sorry for my english xD

Do you know how to get into your BIOS? smile.gif

Yes, but I have not quite clear what the frequencies, I'm new to this, necessitas help making a slight overclock and do not want to burden my CPU.

My ram is 800mhz DDR2, i set my multiplier to 7.5 and my FSB to 400.. ^^ i dont think you dont need to adjust voltages smile.gif

Thanks for the information, i have ram 1333 mhZ i can up to 1600 Mhz?

im not quite sure, my ram got REALLY hot when i accidentally turned them up to 900 some mhz.. im not sure smile.gif

this is a very basic explanation of overclocking

its basic maths. your Q8300 is rated at 1333mhz. you always divide this number by 4 so 1333/4= 333, this is your fsb. (or cpu frequency)
then your processor (cpu) has a multiplier of 7.5 (or cpu ratio)
so 333 x 7.5 = 2500mhz or 2.5GHz

can you raise the fsb? yours is now 333. try rising it to 350
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.
keep an eye on temps (do not let it go over 70.C) iirc.

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.
you are fine upto 1.36v

the trick is to do this step by step, just take your time

also if going down this route, please get a proper cpu cooler.
there is a for sale section on this forum.
or a decent budget cooler is the Hyper 212+ and should get you a higher overclock.
also your motherboard is not that good for overclocking

also here are some bios settings, but these are on a different motherboard, so may not work on yours.

Oveclocking 3600Mhz default voltage in bios 1,2875V cpu-z show 1,250V
Load Line Calibration = Disabled
C1E support = Disabled
Intel Speed step = Disabled
FSB :480Mhz NB=1,41V ,Cpu PLL volt= 1,56V,FSB Termination Voltage = 1,26V
FSB strap to NB : 333Mhz
other options AUTO.
Cpu power consumption 3600Mhz 1,2875V = only 60[W]
Q6600 = more than 100watts
All 4-core temps are under 50C,Zalman CNPS9500 led,high 12V (2700rpm)
