Hi folks,

i want to try to overclock my new e8400 to hit at least 3.4ghz, and no more than 3.6ghz. on asus p5ql pro mobo.
Im using stock cooler now, so i think i need netter cooling if im not mistaken, any suggestion?

Also how do i overclock it? should i go to the
mobo settings?

im à nood in oc world, but is there à way to reach 3.6 with only changing one setting? So not the voltage?


Pls this newbie :)  thx

yes use the bios, not any software based programs. E8400's are easy. set multiplyer to 9 which is max on those and fsb to 400. 3.6 the easy way. up the voltage only .1 of a volt. mine was 1.25v if i remember so go to 1.35v. should reboot stable but obviously stress test it. if it passes drop voltage down in smallest increments till unstable and go back to last stable voltage. should run stable at just over stock voltage at those clocks. depending on your boards vdrop that is.

This should be your first stop.
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1

This should be your second stop. You need to know something about thermal management or you can fry your CPU. It's actually kind of difficult to fry a modern CPU, but it is possible.

Third stop will be a guide for your particular motherboard. Google is your friend.

You will need better cooling. Here are two under $50 heatsinks that are pretty popular:
Sunbeam

Xigmatec Dark Knight
http://www.newegg.com/Product/Prod [...] 6835233029

They both require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.

Go through the first two threads. Do not do anything until you have a good idea about what you are trying to do. Once you have definite questions (you will, you will :) ), come back and ask.

Keep in mind that these are guides, not cookbooks. YMMV. Your Mileage May Vary. Because of all the variables, you may not do as well as someone else with a similar system. Or you might do better.

As suggested above, your chipset is capable of a bus speed of 400 MHz
(1600 MHz quad-pumped).

So, just make that one change in the BIOS, and also
enable SpeedStep if it's not enabled.

Download and install CPU-Z to confirm the "Bus Speed" and "Rated FSB"
(using CPU-Z nomenclature).

"Rated FSB" = "Bus Speed" x 4

Don't you mean disable SpeedStep - as in turn off the automatic drop to a X6 multiplier? :)
