Product Description

The MB884 LGA 775 Pentium® 4 motherboard incorporates the Intel 915G chipset that can utilize a single LGA775 processor of up to 4.0GHz or higher and supports FSB frequency of 533/800Mhz (133MHz, and 200MHz HCLK respectively).

The 915G 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, Hub Interface and PCI Express graphics interface.

Two DDR memory sockets supports DDR 400/333 SDRAM DIMM modules of up to 2GB in capacity.

The board is designed with two Marvell 88E8053 PCI Express Gigabit LAN single controllers. Four Serial ATA connectors offer 1.5 Gigabits/sec data throughput speed - faster than the most advanced parallel ATA.

Expansion is provided by two PCI, one PCI Express x1 slots and one PCI Express x16 slots. Other advanced features include six USB 2.0 ports, IrDA interface, digital I/O, two serial ports, watchdog timer and audio function. Dimensions of the board are 9.5” by 9.5” (244mm x 244mm) in a Micro ATX form factor.

INSTALLATIONS

Installing the CPU

The MB884 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.

MB884 User’s Manual

INSTALLATIONS

ATX Power Installation

The system power is provided to the motherboard with the ATX1 and ATX_12V power connectors. ATX1 is a 24-pin power connector and ATX_12V is a 4-pin 12V power connector.

The 24-pin power connector can to be connected to a standard 20-pin ATX power connector in a standard ATX power supply (Min. 400watt).

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

Installing the Memory

The MB884 motherboard supports two DDR memory sockets for a maximum total memory of 2GB 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 is for one channel and DIMM2 is for another channel.

Basically, the system memory interface has the following features: Supports two 64-bit wide DDR data channels

Available bandwidth up to 3.2GB/s (DDR400) for single-channel mode and 6.4GB/s (DDR400) in dual-channel mode.

Supports 128Mb, 256Mb, 512Mb, 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)
