510W Power & Q9550

Dear All,

I want to OC my system (GA EP45-UD3R, 2x2GB GEIL 1066@6-6-6-18, Q9550, Acbel 510W) in order to load it at 50-75% running my C++ Code for constantly 2-4 days long.
I have a Cooler Master Hyper 212 plus my CPU T. @ 2.83 (25% constant load) is 35C but its Cores are at #0: 37-41C #1: 33-37C #2: 37-40C but #3: constant 41C.

How much can I OC it, keeping in mind that the PowerS. is 510 W?

  1. I would expect you should get a stable 3.4g ~ 3.8g, possibly higher with no problems.

    Stability is going to be very important to you, so you shouldn't overclock to the bleeding edge of stability. And I recommend stress testing for 24 hours with Prime95.

    As far as overclocking is concerned:

    It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.

    Go through the guides. Then go into the BIOS and change the System Memory Multiplier from AUTO to 2.00B. Then when you increase the FSB, the memory clock will rise in proportion to it. At stock FSB of 333 MHz, your memory clock should be at 667 MHz.

    Download CPU-Z to check your FSB:RAM ratio. Keep it at 1:1. Overclocking RAM will not help performance much and it can contribute to instability.
