Introducing the Motherboard
Introduction
Thank you for choosing this motherboard of great performance and with enhanced
function. This motherboard is designed to fit the AMD K8 processors in the 754-pin
package. Two 184 pin unbuffered DDR SDRAM DIMM sockets support up to 2 GB in
total memory. Based on the uATX form factor, this motherboard incorporates the
following chipsets: K8M800 chipset family Northbridge and VT8237R Southbridge
chipsets.
The K8M800 Northbridge features the Hyper Transport Technology to transfer of 1600
MT/s, 1200 MT/s, 800 MT/s or 400 MT/s each direction simultaneously, providing a
total maximum data transfer bandwidth of 6.4GB/sec. The AGP controller is AGP v3.0
compliant 8X/4X transfer mode with up to 2.1 GB/sec data transfer rate. The K8M800
Northbridge interconnects to the South Bridge through the high speed 8X 66 MHz (533
MB/sec) V-Link interface.
The VT8237R Southbridge is a highly integrated peripheral controller, it includes an
integrated keyboard controller with PS2 mouse support, dual-channel Serial ATA/RAID
hard disk controller, master mode enhanced Parallel IDE controller with full scatter/
gather capability and extension to UltraDMA-133/100/66 for 133/100/66 MB/sec
transfer rate, integrated USB 2.0 interface and OnNow/ACPI compliant advanced
configuration and power management interface. The VT8237R features outstanding
expansion capibility such as, three PCI slots with PCI v2.2 compliant. The VT8237R
integrated Fast Ethernet controller with standard MII interface to an external PHY for
10/100Mb Base-T Ethernet.
There is an advanced full set of I/O ports in the rear panel, including PS/2 mouse and
keyboard connectors, COM1, LPT1, four USB ports at the rear I/O and 2 headers
onboard , one LAN port (optional), and audio jacks for microphone, line-in, and line-
out. This motherboard is designed in an uATX form factor using a four-layer printed
circuit board and measures 244 mm x 200 mm.
