MB Intelligent Tweaker page in BIOS, MIT, is where the major tweaking and overclocking will be carried out.

Spread Spectrum Control, just a requirement for board makers, are usually disabled by me.

The very interesting page of System Clock setting:

You get to choose whether you want to Link or Unlink FSB and your Memory Clocks. I typically unlink when overclocking.

CPU FSB Frequency is adjustable from 100MHz to 650MHz, selectable, but FSBs in excess of 500MHz is highly unlikely workable, usually on most 650i motherboards. As you can see, the default 200MHz FSB of my E4300 was adjusted to 267MHz FSB - 267 instead of 266 which weirdly doesn't bootup: a buggy number. Also Memory was set at 802MHz, so that it will run 800MHz as this board tends to round off to the lower step, so compensating it by 1-2MHz actually brings it to the speed you initially wanted.  Memory frequency adjustable up to 1400MHz DDR.

Crucial to overclocking of course are the key voltage adjustments offered by this motherboard:

Memory Voltage up to 2.6v from 1.85v, Northbridge C55 voltage up to 1.6v from 1.25v, FSB AKA CPU VTT Voltage up to 1.6v from 1.25v, Southbridge Voltage up to 1.8v from 1.5v.

This voltage seems to be some sort of I/O voltage.
