Introduction of VIA P4M890 Chipset Motherboards
1-1 Feature of motherboard
The VIA P4M890 Chipset motherboard series are designed for the use of Intel Pentium 4&
Celeron Processor in LGA775 Package Processor with the VIA P4M890 Chipset that delivers a
high performance and professional desktop platform solution. It utilizes the LGA 775 design
and the memory size which is expandable to 2.0GB.
The VIA P4M890 Chipset motherboard series utilize the newest VIA P4M890 chipset which
supports 400MHz/ 533MHz /800MHz/1066MHz System Bus in data transfer rate and Hyper
Threading technology. The VIA P4M890 Chipset motherboard series provide
133MHz/166MHz/200MHz Memory clock frequency for DDR2 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 P4M890 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
compatibility.
The VIA P4M890 Chipset motherboard series are integrated S3 Graphics UniChrome Pro
Integrated Graphics Processor with high performance & high quality 3D accelerator that
supports Ultra-AGPII with 2GB/s bandwidth, built-in MPEG-2/1 Video Decoder and Video
Accelerator supports VCD DVD HDTV decoding and playback, supports graphic and video
overlay function. Built-in programmable 24-bit true-color RAMDAC up to 250MHz pixel
clock. Programmable frame buffer size from 16MB and up to 64MB. For those wanting even
greater graphic performance. The VIA P4M890 Chipset motherboard series provide one PCI-
Express x16 graphics slot of 4Gbyte/sec data transfer rate at each relative direction which get
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, over 3.5 times more bandwidth than
PCI at 133Mbye/sec.
With USB controller as well as capability of expanding to 8x USB2.0 function ports
delivering 480Mb/s bandwidth and rich connectivity, the motherboards meet future USB
demand also have built-in hardware monitor function to monitor and protect your computer.
The motherboards provide high performance & meet future specification demand. It is really
wise choice for your computer.
