After an easy installation we arrive here at the BIOS screen. Since this
is the BIOS screen that most of us have been using since we first put
fingers on a keyboard, it's no problem finding all the important
settings very quickly. In fact, Gigabyte has done away with the need to
press CTRL-F1 at this main menu to unlock all the features of the BIOS.
This lets us Overclockers get right right work.

From the Motherboard Intelligent Tweaker (M.I.T.) we can control all of
the important overclocking parameters. The Robust Graphics Booster and
CPU Intelligent Accelerator (C.I.A.2) are Gigabyte speed boosting
technologies designed to maximize system performance. It takes the right
combination of hardware and patience with all the settings the
motherboard has to find a combination that works with these kinds of
features. So it's nice to have them, but they aren't really necessary to
get a good overclock. Once you enable control of the CPU Host Clock
Control, you'll be able to change the bus speeds and start your
overclocking adventure.

The
CPU host frequency can be set between 100 Mhz and 600 Mhz. That's a raw
bus speed BEFORE the quad pump FSB of the CPU itself. The most
successful overclock that I've ever seen was using a 300Mhz bus speed.
So it seems you'll be digging deeper for a CPU to handle what this board
is claiming to supply.

Another important aspect of Overclocking is the memory multiplier. Since
the board officially supports a 266 Mhz (1066 Mhz after quad pump) front
side bus, a wide range of multipliers are supplied to enable
compatibility with PC2-4300/DDR2-533.

Another feature meant to speed up the setup process is the Memory
Intelligent Booster 2. This is a feature found in almost all Gigabyte
motherboard BIOS setup routines and is designed to optimize the memory
performance based upon the manufacturer of the installed memory. The
above screen shot shows which vendor and brand of memory are compatible
with these options.
