1-3

ASUS EPU

The ASUS unique power saving technology.

System power saving by detecting current PC loadings and intelligently moderating power in

real-time. Smart power saving without interrupting your work.

ASUS EZ DIY

ASUS EZ DIY feature collection provides you with easy ways to install computer components,

update the BIOS or back up your favorite settings.

ASUS O.C. Profile

The motherboard features the ASUS O.C. Profile that allows users to conveniently

store or load multiple BIOS settings. The BIOS settings can be stored in the CMOS or

a separate file, giving users freedom to share and distribute their favorite overclocking

settings. See page 2-24 for details.

ASUS CrashFree BIOS 3

The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a

bootable floppy disk, a USB flash disk or the motherboard support DVD containing the

BIOS file. See page 2-5 for details.

ASUS EZ Flash 2

EZ Flash 2 is a user-friendly BIOS update utility. Simply launch this tool and update

BIOS from a USB flash disk before entering the OS. You can update your BIOS only in

a few clicks without preparing an additional floppy diskette or using an OS-based flash

utility. See page 2-3 for details.

1.3.3

ASUS Stylish features

ASUS MyLogo2™

This feature allows you to convert your favorite photo into a 256-color boot logo for a more

colorful and vivid image on your screen. See page 2-21 for details.

1.3.4

ASUS Intelligent Overclocking features

Precision Tweaker

This feature allows you to fine tune the CPU/memory voltage and gradually increase the

memory Front Side Bus (FSB) and PCI Express frequency at 1MHz increment to achieve

maximum system performance. See page 2-12 to 2-13 for details.

C.P.R. (CPU Parameter Recall)

The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the BIOS default

settings in case the system hangs due to overclocking failure. When the system hangs due

to overclocking failure, C.P.R. eliminates the need to open the system chassis and clear the

RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the

CPU default settings for each parameter.
