P55 Motherboard Round-up: Asus, EVGA, GB, Intel, MSI

Test Setup and BIOS Options

How we configured our test systems:  Before testing, we visited each motherboard's product page to download the latest BIOS available. Then we flashed the BIOS to the latest revision and moved to the next step. When configuring our test systems for this article, we set each board to its optimized defaults. After saving the settings, we re-entered the BIOS and set the memory for DDR3-1600 with CAS 9 timings. The hard drive was formatted, and Windows 7 Pro 64bit installed. Once Win 7 installation completed, we updated the OS and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, defragged the hard drives, and ran all of the tests.

Asus P7P55D Deluxe BIOS
American Megatrends

First up is the American Megatrends BIOS found on the Asus P7P55D Deluxe. We updated the board with version 1207, which came out December of 2009. It features several menu options found along the top edge of the screen, with modifiable settings logically displayed within each tab. Frequency and voltage changes can be done under the AI Tweaker menu as it provides a wealth of options for overclocking. This BIOS also allows users to store up to eight profiles.

EVGA also uses an American Megatrends BIOS for their line of motherboards. We used BIOS version A39 which came out in October of last year. The P55 SLI offers a ton of overclocking options under the Frequency/Voltage Control menu and allows you to save up to four different configuration profiles.

American Megatrends BIOS is also found on the Classified 200 motherboard. Version A39 was used for testing.

Gigabyte P55-UD4P BIOS
Award Software


Gigabyte has made use of Award BIOS for quite some time and we've grown accustomed to the layout and menu options. Overclocking settings are found in the MB Intelligent Tweaker (MIT) menu. Within this area, there are sub-menus containing advanced settings and wealth of options for those who are practiced in the dark arts.

Gigabyte P55M-UD4 BIOS
Award Software


The Gigabyte P55M-UD4 uses the same Award BIOS described above. For testing, we updated the board with BIOS version F6 which was released December 2009.

Gigabyte P55A-UD6 BIOS
Award Software


The BIOS found on the Gigabyte P55A-UD6 also comes from Award Software, with similar options.



Intel designs the BIOS for its motherboard line, so its unique and may take a little time to get used to. But like their boards, the BIOS is simple and intuitively laid out. For systems tweaks, we headed over to the Performance tab which enabled us to modify frequencies and voltages.

American Megatrends


Like Asus and EVGA, another company utilizes American Megatrends for their BIOS. We updated the board with BIOS verson 1.6, which was released late in December 2009. Navigating within the menus was easy enough and categories were logically divided. Overclockers will head directly for the Cell Menu, where a wide range of system settings are available for modification. Users are able to save up to six overclocking profiles for later use.
