INSTALLATIONS

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.

6 IB940 User’s Manual

INSTALLATIONS

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 m odule 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.
