Product Description
®
The MXIH SERIES Pentium
4/Celeron 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 support DDR 400/333/266 SDRAM DIMM
modules of up to 4GB in capacity. ECC is also supported.
®
The board also comes with integrated 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.

MXIH Series CyberResearch® Motherboards
Installing the CPU
The MXIH SERIES motherboard supports a Socket 478 processor socket for
®
Intel
Pentium® 4 & Celeron 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 can cause
your system to hang or be unstable.
The system power is provided to the motherboard with the ATXP1 and ATXP2
ATX power connectors. ATXP2 is a 4-pin 12V power connector. ATXP1 is to
be connected to a standard ATX power connector.
Installing the Memory
The MXIH SERIES motherboard supports four DDR memory sockets for a
maximum total memory of 4GB in DDR memory type. You can install
unbuffered & ECC DDR DIMMs. It supports DDR266 when installed with
CPUs that have clock speeds of 400MHz. It supports DDR266/333 when
installed with CPUs that have clock speeds of 533MHz. It supports
DDR266/320/400 when installed with CPUs that have clock speeds of
800MHz. The board provides dual channel functionality for its DIMM slots.
DIMM1/2is for one channel and DIMM3/4 is for another channel. Enabling
dual channels can increase data access rates by putting two similar-size DDR
modules into two same-color DIMM slots.
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 ECC DIMMs.
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)
