Product Description
The MB820 Pentium®4 motherboard incorporates the Intel 875P chipset
that can utilize a single PGA478 processor of up to 3.2GHz or higher
and supports FSB frequency of 400/533/800Mhz (100Mhz, 133Mhz,
and 200Mhz HCLK respectively).
The 875P chipset is designed for use with the Pentium®4 processor with
512-KB L2 cache on 0.13 micron process. The integrated MCH
component provides the CPU interface, DDR interface, AGP interface,
Hub Interface and AGP 8X graphics interface.
Four DDR memory sockets supports DDR 400/333/266 SDRAM
DIMM modules of up to 4GB in capacity. ECC is also supported.
The board also comes optional with either integrated 10/100MB LAN
support or an Intel®82547GI Gigabit LAN controller. Two Serial ATA
connectors offer 1.5 Gigabits/sec data throughput speed - faster than the
most advanced parallel ATA.
Expansion is provided by four PCI slots, two ISA slots and one AGP8X
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 MB820 motherboard supports a Socket 478 processor socket for
Intel®Pentium®4 processors.
The Socket 478 processor socket comes with a lever to secure the
processor. Raise this lever to about a 90°angle to allow the insertion of
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, return the
lever to the lock position. Refer to the figures below.
After you have installed the processor into the socket, check if the
jumpers for the CPU type and speed are correct.
NOTE: Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.
