Introduction of VIA P4M900 Chipset Motherboards
1-1 Feature of motherboard
The VIA P4M900 chipset motherboard series are designed for the innovative 65nm and 90nm
Dual-Core Intel® Pentium® D Processor 8 and 9 Series, Intel® Pentium® D Processor, and
Intel® Core 2 Duo® (Code Name: Conroe) Processor with Intel® Hyper-Threading
Technology. With the cost-effective VIA P4M900 chipset that delivers a high performance and
professional desktop platform solution.
The VIA P4M900 chipset motherboard series implement VIA P4M900 chipset which supports
400MHz/ 533MHz /800MHz/1066MHz system bus of data transfer rate and Hyper Threading
technology. The VIA P4M900 chipset motherboard series provide 333MHz/266MHz/200MHz
memory clock frequency for DDR2 667/533/400 system RAM Modules. The motherboard
series are embedded with VIA VT8237R PLUS South Bridge offers ULTRA
ATA 133
and
Serial ATA with
RAID 0, 1, JBOD
functions to provide speedier HDD throughout that
boosts overall system performance. The VIA P4M900 Chipset motherboard series implement
the VIA
VT6103L LAN PHY
chip Support Fast Ethernet LAN function provide 10/100 Mb/s
data transfer rate.
The motherboard series also have an integrated 6-channel
AC’97 CODEC
on board which is
fully compatible with Sound Blaster Pro
®
that gives you the best sound quality and

Featuring the VIA Chrome9™ HC IGP (Integrated Graphics Processor) core, the VIA
P4M900 delivers DirectX® 9 graphics support with hardware pixel shaders to meet the
requirements of the upcoming Windows® Vista™ operating system, and rising high
definition video requirements. The core of the VIA P4M900 North Bridge lies the VIA
Chrome9™ HC IGP, delivering a rich visual experience through the implementation of
innovative features such a 128 bit 2D/3D engine with dual pixel pipeline. The P4M900 also
features extensive display support for all HDTV output formats including 1920x1080p and
additional advanced graphics capabilities include the Chromotion Video Display Engine,
comprehensive de-interlace support, and DuoView™ for enhanced productivity and
presentation capabilities
.
The VIA P4M900 chipset motherboard series provide one PCI-Express x16 graphics slot of
4Gbyte/sec data transfer rate at each relative direction which gets 3.5 times of bandwidth
more than AGP8X and it’s up to a peak concurrent bandwidth of 8Gbyte/sec at full speed to
guarantee the fully operational GPU graphics power; one PCI Express x1 I/O slot offers
512Mbyte/sec concurrently which is 3.5 times bandwidth more than PCI at 133Mbye/sec.Two
32-bit PCI slots guarantee the rich connectivity for the I/O peripherals.
