The Dual-BIOS options available on the GA-8I955X Royal, offer familiar features to anyone who tinkers around in the AWARD/PHOENIX BIOS settings menus and is easy to navigate, control and monitor your system through. My 3.4GHz EE just plains bites at overclocking being pushed to its silicon limits as it is, so achieving a ten percent increase is all I was able to attain using that chip and our standard setup parts. The BIOS had a bit of trouble recognizing the 3.8GHz and the board ran hot with both it and the 3.2GHz Dual-Core CPUs we had in the lab, at least until we flashed the BIOS to the latest release candidate. Adjustments that allow for tweaking of the CPU and the memory's FSB, Clock Speed and voltage settings are all available and the results you get will result heavily on what system parts are being used. The slower CPUs seem to do better in the overclocking environment than the Extreme Edition series CPUs so ff overclocking is your main priority, I would research which LGA775 CPUs overclock the best in most cases before buying it. Many of the lower speed CPUs seem to offer better headroom for overclocking than the Extreme Edition CPUs.
Gigabyte also uses a dual-BIOS system that helps maintain boot integrity by automatically switching to the secondary BIOS in case you accidentally make a bad BIOS upgrade or the primary BIOS fails for some reason or another. Their Easy Tune 5 also allows auto overclocking within the Windows environment and is a simple and safe way for beginners to take a stab at overclocking without the fear of a non-booting or damaged system. They also have in the BIOS the M.I.T (Motherboard Intelligent Tweaker) that will also automatically increase system performance when engaged. Many users start off by using some kind of auto-tool if they feel inclined to experiment with overclocking. The Easy Tune 5 also lets the user update the BIOS via Gigabyte's Live Update feature as well as monitoring your PCs temperatures and fan speeds. Gigabyte boards in general have always been modest when it comes to their success at overclocking. We actually were sent the so-called latest BIOS from Gigabyte that supposedly added performance, but actually was a problematic causing us to RMA the first board we were shipped, as after the flash the board was unusable and would never post again. The second board had no problems with updating the BIOS, but still had problems in other areas that caused a severe delay in this review.
