ATTENTION:
It is strongly recommended that only heatsinks that have corresponding
(metal) backplates are used on the CPU card. This is to avoid the CPU
card being bent/distorted, causing the CPU card to become damaged. A
reference picture of a backplate and heatsink that has backplate are
shown below.

Product Description
The IB865 Pentium 4CPU card incorporates the Intel 865G chipset that
can utilize a LGA775 processor of up to 3.8GHz or higher and supports
FSB frequency of 533/800Mhz (133Mhz, and 200Mhz HCLK
respectively).
The 865G chipset comes with a Graphics Memory Controller Hub
(GMCH) designed for use with the Pentium 4 processor with 1MB L2
cache on 0.09 micron process. The GMCH component provides the CPU
interface, DDR interface, AGP interface, Hub Interface, and integrated
graphics with display interfaces.
Aside from CRT support, the VGA function feature a Micro AGP slot
for optional daughter cards:
IBA120: with Chrontel CH7017 chipset that supports dual channel
LVDS, TV-out interface
IBA110: with ATI M7CSP32, M9CSP64 / M10CSP64 chipset,
64MB/32MB frame buffer and supports dual channel LVDS
interface, TMDS and CRT2 display function.
The board also has one Intel 82547GI Gigabit LAN and an Intel 82551
10/100MB fast Ethernet LAN.
Other advanced features include two Serial ATA ports, four USB 2.0
ports, IrDA interface and audio function.

Installing the CPU
The IB865 CPU card supports a 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.

INSTALLATIONS
IB865 User’s Manual 7
ATX Power Installation
The system power is provided to the CPU card with theCN1 andJ7 ATX
power connectors. Please note that theJ7 external ATX power connector
should be connected to the backplane for IB865 to function.J7 is a 3-pin
power connector. CN1 is a 4-pin 12V power connector. CN1 is to be
connected to the ATX power supply.
Installing the Memory
The IB865 CPU card supports two DDR memory sockets for a maximum
total memory of 2GB in DDR memory type. You can install unbuffered
& non-ECC DDR DIMMs. 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 is for
one channel and DIMM2 is for the other channel. Enabling dual
channels can increase data access rates.
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 non ECC DIMMs.
Supports 128Mb, 256Mb, 512Mb 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)
