The Intel®P965 Express Chipset is the latest chipset designed to support 8GB
of dual-channel DDR2 800/667/533 architecture, 1333(O.C)/1066/800/533 FSB
(Front Side Bus), PCI Express x16 graphics and multi-core CPU. It especially
includes the Intel® Fast Memory Access technology that significantly optimizes
the use of available memory bandwidth and reduces the latency of the memory
accesses.
DDR2 memory support
The motherboard supports DDR2 memory that features data transfer rates of
800/667/533 MHz to meet the higher bandwidth requirements of the latest
3D graphics, multimedia, and Internet applications. The dual-channel DDR2
architecture doubles the bandwidth of your system memory to boost system
performance, eliminating bottlenecks with peak bandwidths of up to 12.8 GB/s.
Without restriction to the memory size across the two channels, the motherboard
allows you to install DIMMs with different memory size and enjoy dual-channel
feature at the same time. See pages 2-13 to 2-17 for details.

ASUS P5B SE 1-3
Serial ATA 3 Gb/s technology and SATA on the go
This motherboard supports the next-generation hard drives based on the Serial
ATA (SATA) 3Gb/s storage specification, delivering enhanced scalability and
doubling the bus bandwidth for high-speed data retrieval and saves. The external
SATA port located at the back I/O provides smart setup and hot-plug functions.
Easily backup photos, videos and other entertainment contents to external devices.
See pages 2-25, 2-27, and 2-28 for details.
S/PDIF digital sound ready
This motherboard provides convenient connectivity to external home theater audio
systems via coaxial and optical S/PDIF-out (SONY-PHILIPS Digital Interface) jack.
It allows to transfer digital audio without converting to analog format and keeps the
best signal quality. See page 2-28 for details.
High Denition Audio
Enjoy high-end sound quality on your PC! The onboard 6-channel HD audio (High
Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192
KHz/ 24-bit audio output and jack-sensing feature! With CODEC, 6-channel audio
ports, and S/PDIF interfaces, you can connect your computer to home theater
decoders to produce crystal-clear digital audio. See pages 2-24 and 4-23 for
details.
1.3.2 ASUS Special features
ASUS Q-Fan technology
The ASUS Q-Fan technology smartly adjusts the CPU fan speed according to the
system loading to ensure quiet, cool, and efficient operation. See pages 2-30 and
4-28 for details.
ASUS O.C. Prole
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
settings. See page 4-34 for details.
ASUS CrashFree BIOS 3
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a
USB flash disk containing the BIOS file. See page 4-8 for details.

1-4 Chapter 1: Product introduction
ASUS Q-Connector
ASUS Q-Connector allows you to easily connect or disconnect the chassis front
panel cables to the motherboard. This unique module eliminates the trouble of
connecting the system panel cables one at a time and avoiding wrong cable
connections. See page 2-34 for details.
ASUS EZ Flash 2
EZ Flash 2 is a user-friendly BIOS update utility. Simply press the predefined
hotkey to launch the utility and update the BIOS without entering the OS. Update
your BIOS easily without preparing a bootable diskette or using an OS-based flash
utility. See pages 4-5 and 4-33 for details.
ASUS MyLogo™
ASUS My Logo is the new feature present in the motherboard that allows you to
personalize and add style to your system with customizable boot logos. See page
5-9 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. When the
system hangs due to overclocking, 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 setting for each parameter. See page
2-22 for details.
