Hey guys i recently put together my PC with the following:

Asus P5Q-E
Intel Quad Core Q9550 @2.8GHz
4GB RAM DDR2 800MHz Kingston
Nvidia 9800GTX+
Cooler Master 550watt PSU

BTW I have 3 fans plus the one on the CPU heatsink

I'm kind of a noob when it comes to Overclocking so what i wanted to ask the community is what voltage would I have to enter on the BIOS for the CPU to reach 3.2GHz or 3.4GHz and if it would alter dramatically my temperatures..

Thanks.. My email is facu.alegre@gmail.com

Hitting 3.0 GHz should be a piece of cake with a Q9550. In the BIOS, set your memory multiplier to 2.0. Set your FSB freq to 350 MHz. You might need to increase CPU core voltage a little.

For anything more:

This should be your first stop.

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.

For anything higher than about 3.0 GHz, you will need better cooling. Here are two under $50 heatsinks that are pretty popular:

Xigmatec Dark Knight

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.

Wow thank you very much.. I will take my time to read very carefully and let you know how it goes.. Thanks..

The max multiplier on the Q9550 is 8.5, so ...

3200 MHz / 8.5 = ~ 375 MHz FSB

The FSB on the P45 chipset supports 1600 MHz (400 quad-pumped),
so reaching 375 MHz shouldn't be too hard.

We're running our Q9550 with an FSB = 400 MHz Bus Speed x 8.5 = 3.4 GHz rated FSB
(using CPU-Z nomenclature).


You don't need an expensive HSF: just get
rid of the stupid push pins and replace them
with an LGA775 bolt-thru-kit ($5. USD):

... a very cost-effective solution.
