Product Description
The MB880 LGA 775 Pentium®4 motherboard incorporates the Intel
i915G 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 i915G 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 three PCI slots, two ISA slots andone external
PCI Express graphics card interface. Other advanced features include
six USB 2.0 ports, IrDA interface, PCI to ISA bridge, digital I/O, four
serial ports, watchdog timer and audio function. Dimensions of the
board are 12”by 9.5”in an ATX form factor.

Installing the CPU
The MB880 motherboard supports anLGA 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.
