Locate the FSB adjustment. Hopefully, your BIOS has a display here that shows the CPU's current operating frequency, so you can watch your CPU speed change as you increase the FSB. Be aware that some BIOS have this located in a different menu, other BIOS do not have this display at all.

Generally you should raise the FSB a few numbers at a time by pressing the “+” key, and reboot to see if the overclock was successful. I'd recommend this method, as it is usually easier to determine what caused an unsuccessful overclock, than increasing by a large increment at one time. It is very tedious though; successful overclocking takes a lot of patience.

The MIT menu on this motherboard is set up nicely for overclocking. I can see the current CPU speed and the memory speed from the same location as the FSB adjustment, so as I raise the FSB, I can watch both speeds increase.


Here, I have raised the FSB to 300. Notice that the CPU speed has increased to 2.7gHz, and the memory speed has increased to 900mHz. I'd recommend in your initial overclocking attempts that you try to keep your memory speed close to stock, to make it easier to determine why an overclock failed. This motherboard has two settings used for changing the memory divider (called multiplier on this BIOS), the “System Memory Multiplier”, and the “MCH Frequency Latch”. Keep in mind that different motherboards perform this function in different ways.

Changing the System Memory Multiplier gives you two or three different dividers. Change the Frequency Latch, and you get a new set of dividers. Between the two you will get a wide variety of dividers, but be aware, all of these are lowering dividers. The easiest thing to do is play around with them until you find a speed close to the memory's stock speed.


Once I raised the FSB, I pressed the “F10” key, which is the shortcut key for “Save and Restart”. This is true for every motherboard I have owned.
