Introducing the Mainboard
Introduction
Thank you for purchasing the MS9127C mainboard. The MS9127C is designed to accommodate Intel Pentium 4 processors supporting front side bus
(FSB) speeds of 400/533 MHz.
The mainboard is an ATX mainboard that uses a 4-layers printed circuit board
and measures 305 mm x 190 mm.
Based on the highly integrated VIA APOLLO P4X400, this mainboard incorporates the VIA VT8754 Northbridge and VT8235 Southbridge chipsets which
delivers workstation level performance.
The MS9127C comes with a full set of I/O features conveniently integrated on
the rear I/O panel, including support for PS/2 keyboard and mouse connectors,
Six USB ports (Four back-panel USB 2.0 ports, onboard USB headers providing maximum two extra ports) , a LAN connector, two high-speed serial port,
an EPP/ECP parallel port, audio jacks for microphone, line-in, line-out and
CD-in, as well as supporting Plug and Play.
For added power and performance, the mainboard achieves the highest reliability by supporting three 184 pin, 2.5V DDR (Double Data RAM) DIMM
sockets with a total capacity of 3 GB.
The MS9127C offers the ideal platform for building powerful PCs and workstations.
Note: SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz. Double Data Rate SDRAM
(DDR SDRAM) doubles the rate to 1.6 GBps and 2.7 GBps. DDR
SDRAM uses additional power and ground lines and requires 184-pin
DIMM modules rather than the 168-pin DIMMs used by SDRAM.
