The BIOS used by the ASUS P7H55D-M EVO motherboard uses a version of the AMI BIOS, which comes with a look that is unique to ASUS. The AMI BIOS can make simple changes such as setting a first boot device or changing the system date and time. It can also make more complicated changes, such as adjustments to a processors clock speed or setting specific timings for your memory. The changes made in the BIOS affect the overall system performance and stability.
The main section is the first part of the BIOS that you come to when you start up into it. In this section you can control the date and time for the system, control the drives and storage configurations for ACHI or RAID, and view the system information such as the BIOS version, processor model and speed, and the memory size.
The Ai Tweaker section is the menu where the user has the option to adjust the systems settings for enhanced performance. If you have used any ASUS board over the past few years, this section should be very familiar. In this section, you can adjust the CPU speeds, system multipliers, memory dividers, and more. You can control the voltages for everything from the CPU to the chipset and memory. Additional options in this menu consist of DRAM Timings, PCIe Frequency, and HT Link speed. Also in this menu is the Intel SpeedStep option. This is a hardware based utility that can increase the performance of your CPU by automatically adjusting the clock speed during operation. This option should be disabled while overclocking to ensure the CPU does not exceed the maximum stable overclocked speed.
The Advanced section has a lot that you can change. This is where you can change the CPU configuration such as enabling C1E support, Hardware Prefetcher, Adjust Cache Line Prefetch, and set a Max CPUID Value Limit. In the Advanced section are also the video controls you can also make changes to the on-board devices such as the USB functions or selecting the primary video device whether it be the on-board video or a discrete card.
The power menu allows the user to monitor your CPU and motherboard temperatures, fan speeds, as well as see real-time voltage readings.
The Boot section is where you select the boot priority and boot configuration such as Quick Boot, Logo selection, and error messages. You can also assign or remove the BIOS and system passwords to protect your system.
The tools section is where you can control additional features of the board such as flashing the BIOS using the ASUS EZ Flash 2 utility, enabling the Express Gate feature, resetting the data to defaults if needed, loading or saving overclocking profiles using the ASUS O.C. Profile section, and testing the LAN connection using the AI Net 2 utility.
That last tab in the BIOS is the Exit tab and other than just allowing for a easy way to close the BIOS, it also allows the user to load the systems default settings.
