ASUS P5BV(P)-E Series 1-1
1.1 Welcome!
Thank you for buying an ASUS®P5BV-E Series and P5BP-E/4L motherboard!
The motherboard delivers a host of new features and latest technologies, making it
another standout in the long line of ASUS quality motherboards!
Before you start installing the motherboard, and hardware devices on it, check the
items in your package with the list below.
1.2 Package contents
Check your motherboard package for the following items.
If any of the above items is damaged or missing, contact your retailer.

1-2 Chapter 1: Product introduction
1.3 Special features
1.3.1 Product highlights
Latest processor technology
The motherboard comes with a 775-pin surface mount Land Grid Array (LGA)
socket designed for the Intel®Pentium®4 processor in the 775-land package. The
motherboard supports the Intel® Pentium® 4, Intel® Conroe®, Intel® Xeon®, Intel®
wolfdale, and Intel® yorkeld processors with 1333/1066/800 MHz Front Side Bus
(FSB). The motherboard also supports the Intel®Hyper-Threading Technology and
is fully compatible with Intel®O6, 05B/05A or 04B/04A processors. See page 2-6
for details.
Intel®EM64T
The motherboard supports Intel®Pentium®4 CPUs with the Intel®EM64T
(Extended Memory 64 Technology). The Intel®EM64T feature allows your
computer to run on 64-bit operating systems and access larger amounts of system
memory for faster and more efcient computing.
Enhanced Intel SpeedStep®Technology (EIST)
The Enhanced Intel SpeedStep®Technology (EIST) intelligently manages the
CPU resources by automatically adjusting the CPU voltage and core frequency
depending on the CPU loading and system speed or power requirement.
Intel®3200 and Intel®ICH7R chipset
The Intel®3200 or 3210 Memory Controller Hub (MCH) and the Intel®ICH7R (I/O
controller hub) provide the vital interfaces for the motherboard.
The MCH provides the processor, dual-channel DDR2-667/800 memory, and PCI
Express interfaces. The ICH7R is a new generation server class I/O controller hub that
provides the interface for PCI 2.2, USB 2.0, and SATA among others.
DDR2 memory support
The motherboard supports DDR2 memory which features data transfer rates of
up to 800 MHz to meet the higher bandwidth requirements of the latest server
applications. The dual-channel memory architecture doubles the bandwidth of your
system memory to boost system performance, eliminating bottlenecks with peak
bandwidths of up to 12.8 GB/s.
PCI Express™ interface
The motherboard fully supports PCI Express, the latest I/O interconnect technology
that speeds up the PCI bus. PCI Express features point-to-point serial
interconnections between devices and allows higher clockspeeds by carrying data
in packets. This high speed interface is software compatible with existing PCI or
PCI-X specications. See page 2-17 for details.
