Gigabyte addresses overclocking needs with a full array of settings and values to match all but the most extreme configurations.

Gigabyte’s “Motherboard Intelligent Tweaker” menu starts off with CPU multiplier, bus frequency, boot strap, and memory ratio settings.

Scrolling down the M.I.T. menu reveals basic memory timing controls and an “Advanced Timing” sub-menu link.

The bottom of the M.I.T. menu provides critical voltage controls, but only two GTL REF registers.

Chosing “Advance Clock Control” reveals a sub-menu with skew and drive strength settings.

The “Advanced Timing Controls” sub-menu has enough settings to consume nearly two pages.

Up to eight complete BIOS configurations can be stored as user profiles, making it easy to return to a setting that works after trying one that doesn’t.

We didn’t grab a screen shot of the Security Chip menu, since it only shows “Enable” or “Disable”. The Security Chip is a DES feature with 2048-bit hardware-based encryption that can be applied to a hard drive or partition, with keys stored in the BIOS or on a USB flash drive.
