Product Description
The MB886 LGA 775 Pentium®4 motherboard incorporates the Intel
945G chipset that can utilize a single LGA775 processor of up to
4.0GHz or higher and supports FSB frequency of 533/800/1066Mhz
(133MHz(533MT/s), 200MHz(800MT/s) and 266MHz(1066MT/s)
HCLK respectively. MB886 supports Intel® Core™2 Duo processors,
Pentium® D dual core CPU and Pentium® 4 single core CPU. It also
supports EMT64 processors.
MB886 has four DDR2 memory sockets to support DDR2 400/533/667
SDRAM DIMM modules of up to 4GB in capacity. The board is
designed with one Intel 82573L PCI Express Gigabit LAN single
controllers. Four Serial ATA connectors offer 3 Gb/s data throughput
speed - faster than the most advanced parallel ATA.
Expansion is provided by four PCI slots, two PCI Express x1 and one
PCI Express x16. Other advanced features include eight USB 2.0 ports,
IrDA interface, 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.

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 8-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 MB886 motherboard supports four DDR2 memory sockets for a
maximum total memory of 4GB in DDR memory type. It supports
DDR2 533/667.
Basically, the system memory interface has the following features:
Supports two 64-bit wide DDR data channels
Available bandwidth up to 5.3GB/s (DDR2 667) for single-channel
mode and 10.7GB/s (DDR2 667) in dual-channel mode.
