Overclocking Tools
Wel, I'm not sure about the BIOS of your motherboard, but there should be an option where you can adjust the frequency. But, if there isn't, you can use software to OC, as this motherboard has Intel chipset, it will make use of a clock generator, making OCing easy & stable.
You can use any of these tools:
1.) Clockgen --> Old & Discontinued
2.) SoftFSB --> Old
3.) SysTool --> Discontinued & Old
4.) SetFSB --> Best option...
I'm using SetFSB to OC my MSI P35 Platinum mobo, it even supports my Toshiba Satellite Laptop with 945GM chipset (I had to open it to find the correct PLL chip). You should first locate the PLL / Clock Generator chip on your motherboard, then select it from the list in SetFSB to OC. You must select the correct Clock Generator IC, as this can result in a lock-up if you select the wrong one. This IC is used to control the FSB & other frequencies. It is normally located nex to an AGP / PCI-E slot.
