Product Description
TheIB850 Pentium4CPUcard incorporatestheIntel 875P chipset that can
utilize asingle 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 comes with a Memory Controller Hub (MCH) designed
forusewiththePentium4processorwith512-KB L2 cache on 0.13 micron
process. The MCH component provides the CPU interface, DDR
interface, Hub Interface, and AGP8X graphics interface.
Aside from CRT support, the VGA function feature a Micro AGP slot for
optional daughter cards:
IBA110: with ATI M7CSP32, M9CSP64 / M10CSP64 chipset,
64MB/32MBframebuffer andsupportsdual channelLVDSinterface,
TMDS and CRT2 display function.
Two DDR memory sockets supportup to 2GBDDR 266/333/400

Installing the CPU
The IB850 CPU card supports a Socket 478 processor socket for Intel
Pentium 4 processors.
The Socket 478 processor socket comes with a lever to secure the
processor.Raisethislevertoabouta90°angletoallow theinsertionof 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 av
oid CPU overheating problem that would
cause your system to hang or be unstable.

IB850 User’s Manual 9
ATX Power Installation
The system power is provided to the CPU card with the CN1 and J7 ATX
powerconnectors.Please notethatthe J7 external ATX power connector
should be connected to the backplane for IB850 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 IB850 CPU card supports two DDR memory sockets for a maximum
total memory of 2GB in DDR memory type. You can install unbuffered
DDRDIMMswithECCfunction. 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
DDR266/333/400 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 memoryinterface 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/ non-ECC DIMMs.
Supports 128MB, 256MB, 512MBDDR 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)
