Product Description

The MB893 LGA 775 Pentium

4 motherboard incorporates the Intel

i915GV chipset that can utilize a single LGA775 processor of up to

3.8GHz or higher and supports FSB frequency of 533/800MHz

(133MHz, and 200MHz HCLK respectively).

The i915GV chipset is designed for use with the Pentium

4 processor

with 1M Level 2 (CPU integrated) cache. The integrated MCH

component provides the CPU interface, DDR interface and Hub

Interface.

Four DDR memory sockets supports DDR 400/333 SDRAM DIMM

modules of up to 4GB in capacity.

The board is designed with four Marvell 88E8053 PCI Express Gigabit

LAN single controllers and two Intel

82541PI PCI Gigabit LAN single

controllers. ICH6 supports only one primary IDE interface for UDMA

33/66/100 .Two Serial ATA connectors offer 1.5 Gigabits/sec data

throughput speed - faster than the most advanced parallel ATA.

On board expansion is provided by one Mini PCI socket. Additional

expansion is provided by two PCI slot if the board is used with the IP320

backplane bridge board. Other advanced features include two USB 2.0

ports…etc. Dimensions of the board are 12.6” by 7.2”.

Installing the CPU

The MB893 motherboard supports an LGA 775 processor socket for

Intel® Pentium® 4 processors.

The LGA 775 processor socket comes with a lever to secure the

processor. Refer to the pictures below, from left to right, on how to place

the processor into the CPU socket. Please note that the cover of the

LGA775 socket must always be installed during transport to avoid

damage to the socket.

INSTALLATIONS

MB893 User’s Manual 7

ATX Power Installation

The system power is provided to the motherboard with the ATX1 and

ATX_12V1 power connectors. ATX1 is a 24-pin power connector and

ATX_12V1 is an 8-pin 12V power connector.

Note: The power supply 5VSB voltage must be at least 2A.

Installing the Memory

The MB893 motherboard supports four DDR memory sockets for a

maximum total memory of 4GB in DDR memory type. It supports

DDR333 when installed with CPUs that have clock speeds of 533MHz.

It supports DDR400 when installed with CPUs that have clock speeds of

800MHz. The board provides dual channel functionality for its DIMM

slots. DIMM1, 2 is for one channel and DIMM3, 4 is for another

channel.

Basically, the system memory interface has the following features:

Supports two 64-bit wide DDR data channels

Available bandwidth of up to 3.2GB/s (DDR400) for single-channel

mode and 6.4GB/s (DDR400) in dual-channel mode

Supports 128Mb, 256Mb, 512Mb and 1Gb DDR technologies

Supports only x8, x16, DDR devices with four banks

Registered DIMMs not supported

Supports opportunistic refresh

Up to 16 simultaneously open pages (four per row, four rows

maximum)
