ASUS P7P55D Premium and P7P55D-E Pro Review


Closer Look:

The BIOS on both the P7P55D Premium and P7P55D-E Pro are almost identical, except for a few items so I will only show the one BIOS. The BIOS used is an American Megatrends BIOS stored on a 16MB flash ROM. The BIOS is divided into seven sections including the Ai Tweaker section that contains all of the overclocking and performance enhancing tools in this BIOS. I will take a look at each section in turn and discuss what is found in each section.


The Main section of the BIOS contains the time, date, language of choices and storage configuration. The bottom two tabs offer up some top level system information such as the BIOS revision, processor type and clock speed plus the ability to configure the SATA drive interface and disk detection time out.












Ai Tweaker:

In this section you can set all of the performance parameters to allow you to manually overclock your hardware with both full manual control of by using the OC Tuner utility or CPU Level up functions. The voltages, bclock and DRAM settings are all in this section. I will devote an entire page to this section with just the quick look here.




In this section, you can configure the P-n-P, USB, CPU and onboard device functionality. Under the CPU configuration tab you can set all of the Core i5/i7 energy saving features such as C1E, Intel Speed Step and the Thermal monitor function. Under the on board device configuration you can set the drive configuration for the Marvell SATA controller and enable or disable the LAN ports.





This section is where you chose the suspend mode, enable or disable ACPI support, view and configure the fan speed rules as well as monitor CPU voltage, 3.3V, 5V and 12V readings. The CPU and motherboard voltages can be viewed here as well.




In this section, you have the ability to choose which devices you can boot from and what sequence they will be checked in the boot device priority tab. Under the Boot Configuration, you can choose to disable the full screen logo, enable or disable quick boot and whether you want to stop the post process if there are any errors.




Tools is where you enable or disable the ability to use ExpressGate the included Hybrid OS that allows you to boot into a small footprint Linux distribution to gain access to the internet or files on your computer without waiting for the window boot and log on process to complete. In the past this tool has proven to be quite useful. Using ASUS EZ Flash 2 BIOS flash tool is one of the simplest ways to flash the BIOS on an ASUS board and has yet to let me down with a bad flash. ASUS OC Profile lets you store your overclock or perfect system settings so that you can easily return back to a safe point after a night of pushing the limits.



The exit function is pretty self explanatory and is your way out of the BIOS either by saving your setting or not saving the changes you have made. Additionally, you can load setup defaults if you really went off the deep end and are lost with the changes you made. You can either use the OC Profile or the load setup defaults to get back to a good baseline. Now let's look at the Ai Tweaker section to see where the magic happens.
