The Gigabyte board booted the Pentium EE 955 (3.46 GHz) at an overclocked speed of 3.56 GHz. For some reason, Gigabyte had set a default initial clock speed of 274 MHz, which we had to reduce to 266 MHz manually.

The BIOS item "Advanced" allows you to change some basic processor features.

The F8 key will open Gigabyte's integrated BIOS update function. Here you can save the current BIOS to disk or update the BIOS from disk. You can also copy the BIOS content from the primary to the secondary ROM, using Gigabyte's DualBIOS feature.

The DualBIOS feature uses a pair of Flash ROMs to provide two fully-functional BIOSes.

Gigabyte offers the full range of possible overclocking options.

At FSB800 speed, Gigabyte supports the required multiplier for running the memory at DDR2-800 speed.

The C.I.A.2 feature is a simple way for inexperienced users to overclock the system within reasonable boundaries.
