Introduction
Product Description
The IB935 PICMG1.3 SHB board incorporates the Intel® Q35 Express Chipset,
consisting of the Intel® Q35 Graphic Memory Controller Hub (GMCH) and
Intel® I/O Controller Hub 9 (ICH9), is an optimized integrated graphics solution
with a 800/1066/1333 MHz front-side bus.
The integrated graphics engine, based on Intel® Graphics Media Accelerator
3100 (Intel® GMA 3100) architecture, 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 two DIMM
sockets with up to 12.8 GB/s of bandwidth and 4 GB memory addressability for
faster system responsiveness and support of 64-bit computing.
The main features of the SBC are:
Supports Intel Core 2 Duo, Core 2 Quad, and Celeron 400 (Conroe-L)
sequence processor
Two DDR2 667/800 SDRAM DIMM, Max. 4GB

INSTALLATIONS
Installing the CPU
The IB935 board supports an LGA 775 processor socket for Intel Core 2
Duo and Intel Core2 Quad processors, and Intel Celeron 400(Conroe-L)
Sequence processor.
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
Installing the Memory
The IB935 board supports two DDR2 memory sockets for a maximum
total memory of 4GB in DDR2 memory type. It supports DDR2
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 and 12.8GB/s (DDR2 800) in dual-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.
