Chapter 1: Product introduction
Intel G965 Chipset
The Intel® G965 Express Chipset boosts your gaming and multi-media experience
with the integrated graphics engine Intel® Graphics Media Accelerator X3000.
Delivering breakthrough increases in 3D, 2D, and video capabilities, the integrated
chipset meets the changing display requirements of visually rich applications. The
Intel® G965 Express features the Intel® Clear Video Technology, which trailblazes
new standards in high-definition video, crisp imaging, and accurate color control.
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 1-18 for details.
IEEE 1394a support
The IEEE 1394a interface provides high speed digital interface for audio/video
appliances such as digital television, digital video camcorders, storage peripherals
& other PC portable devices. See pages 1-28 and 1-33 for details.
Serial ATA 3.0 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 1-28 and 1-32 for details.
S/PDIF digital sound ready
The motherboard supports the S/PDIF-out (SONY-PHILIPS Digtal Interface)
function through the S/PDIF interface at mid-board. It allows to transfer digital
audio without converting to analog format and keeps the best signal quality. See
pages 1-30 for details.
ASUS P5B-VM
1-3
High Definition Audio
Enjoy high-end sound quality on your PC! The onboard 8-channel HD audio (High
Definition Audio, previously codenamed Azalia) CODEC enables high-quality
192KHz/24-bit audio output, jack-sensing feature, retasking functions and
multi-streaming technology that simultaneously sends different audio streams to
different destinations. You can now talk to your partners on the headphone while
playing multi-channel network games. See page 1-36 for details.
1.3.2
ASUS AI Lifestyle features
ASUS Quiet Thermal Solution
ASUS Quiet Thermal solution makes system more stable and enhances the
overclocking capability.
AI Gear
AI Gear provides four modes that adjust the CPU frequency and Vcore
voltage minimizing system noise and power consumption. You can choose
the mode that best suits your computing needs. See pages 3-4 and 3-8 for
details.
AI Nap
With AI Nap, the system can continue running at minimum power and noise
when you are temporarily away. To wake the system and return to the OS
environment, simply click the mouse or press a key. See pages 3-4 and 3-9
for details.
ASUS Advanced Q-Fan
The ASUS advanced Q-Fan technology on P5B Series is powered by Intel Quiet
System Technology; It makes the change of fan speed more smoothly. It’s better
in fan use, and efficiently reduces the noise caused by fans’ abruptly speeding
up. Moreover, Advanced Q-Fan has a better control over a constant temperature
system environment. See page 2-30 for details.
ASUS Crystal Sound
This feature can enhance speech-centric applications like Skype, online
game, video conference and recording.
Noise Filter
This feature detects repetitive and stationary noises (non-voice signals) like
computer fans, air conditioners, and other background noises then eliminates
it in the incoming audio stream while recording. See page 3-8 for details.

Chapter 1: Product introduction
ASUS EZ DIY
ASUS EZ DIY feature collection provides you easy ways to install computer
components, update the BIOS or back up your favorite settings.
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 1-39 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 2-6 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 page 2-3 for details.
1.3.3
ASUS Special 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 2-31 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.
Due to chipset behavior, AC power off is required prior using C.P.R. function.

Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
•
•
Unplug the power cord from the wall socket before touching any
component.
Use a grounded wrist strap or touch a safely grounded object or
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
•
•
Hold components by the edges to avoid touching the ICs on them.
Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
•
Before you install or remove any component, ensure
that the ATX power supply is switched off or the power cord is detached
from the power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
Onboard LED
The motherboard comes with a standby power LED that lights up to indicate
that the system is ON, in sleep mode, or in soft-off mode. This is a reminder
that you should shut down the system and unplug the power cable before
removing or plugging in any motherboard component. The illustration below
shows the location of the onboard LED.

Motherboard overview
Before you install the motherboard, study the configuration of your chassis to
ensure that the motherboard fits into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and damage
motherboard components.
1.5.1
Placement direction
When installing the motherboard, make sure that you place it into the chassis in the
correct orientation. The edge with external ports goes to the rear part of the chassis
as indicated in the image below.
1.5.2
Screw holes
Place eight (8) screws into the holes indicated by circles to secure the motherboard
to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.

Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for
the Intel® Core™2/Pentium® D/Pentium® 4/Pentium® Extreme and Celeron® D
processors.
•
•
Make sure the AC power is off before you install the CPU.
If installing a dual-core CPU, connect the chassis fan cable to the
CHA_FAN connector to ensure system stability.
•
Upon purchase of the motherboard, make sure that the PnP cap is on
the socket and the socket contacts are not bent. Contact your retailer
immediately if the PnP cap is missing, or if you see any damage to the PnP
cap/socket contacts/motherboard components. ASUS will shoulder the cost
of repair only if the damage is shipment/transit-related.
•
