ATTENTION:
It is strongly recommended that only heatsinks that have corresponding
(metal) backplates be 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.

Introduction
Product Description
The IB940 CPU card is based on the Intel Q965 chipset and supports the
Intel® Core™2 Duo processor with 1066/800/533 MHz System Bus. It
supports the PCI Express x16 graphics interface for the latest
high-performance graphics cards. The PCI Express x1 I/O ports offer up
to 3.5X the bandwidth over traditional PCI architecture, delivering faster
access to peripheral I/O devices.
The Intel GMA 3000 graphics on board supports Dual Independent
Display and delivers richer visual color and picture clarity without the
need for additional discrete graphics cards, and the integrated audio
support enables premium digital sound and delivers advanced features
such as multiple audio.
The CPU card also supports Dual-Channel DDR2 memory in four
DIMM sockets and delivers up to 12.8 GB/s of bandwidth and 8 GB
memory addressability for faster system responsiveness. Dimensions of
the board are 338mm x 126mm.

Installing the CPU
The IB940 CPU Card supports an LGA 775 processor socket for Intel®
Core 2 Duo 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
IB940 User’s Manual 7
Installing the Memory
The IB940 CPU Card supports four DDR2 memory sockets for a
maximum total memory of 4GB in DDR memory type. It supports
DDR2 533/667/800.
Basically, the system memory interface has the following features:
Supports two 64-bit wide DDR data channels
Available bandwidth up to 6.4GB/s (DDR2 800) for single-channel
mode.
Supports 256Mb, 512Mb, 1Gb DDR2 technologies.
Supports only x8, x16, DDR2 devices with four banks
Supports only unbuffered DIMMs
Supports opportunistic refresh
Up to 32 simultaneously open pages (four per row, four rows
maximum)
Installing and Removing Memory Modules
To install the DDR2 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR2 module so that the key of the DDR2 module align
with those on the memory slot.
2. Gently push the DDR2 module in an upright position until the clips of
the slot close to hold the DDR2 module in place when the DDR
module touches the bottom of the slot.
3. To remove the DDR2 module, press the clips with both hands.
