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.
The main features of the CPU card are:
yIntelQ965 Express Chipset Based
ySupport LGA775 IntelCore2 Duo Processors
ySupport FSB 1066/800/533MHz

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.
