GIGABYTE uses the Phoenix Award BIOS for their GA-8I945GMH-RH motherboard. The 945G platform doesn't have much in terms of overclocking features, as Intel boards are notorious for their stability and not for overclocking. The GIGABYTE board does NOT allow the FSB to be changed, limiting overclocking to simply changing the multiplier. The memory multiplier can be changed from 1.50x to 2.00x or 2.50x.
The onboard Devices menu allows you to enable or disable the SATA RAID, LAN, USB controller, HDA, Firewire, and FDD controller. The Advanced Chipset Menu allows you to change the memory timing including the CAS Latency, the RAS Precharge Delay, the RAS Active Delay and the Burst Length. I decided not to include BIOS shots due to the exclusion of overclocking options in the BIOS.
