Chapter 2 Hardware Installation

Chapter 2

The system board supports the following memory interface.

Single Channel (SC)

Data will be accessed in chunks of 64 bits (8B) from the memory channels.

Dual Channel (DC)

Data will be accessed in chunks of 128 bits from the memory channels. Dual channel provides

better system performance because it doubles the data transfer rate.

Single Channel

DIMMs are on the same channel.

DIMMs in a channel can be identical or

completely different. However, we highly

recommend using identical DIMMs.

Not all slots need to be populated.

Dual Channel

DIMMs of the same memory configuration

are on different channels.

Important:

You can populate either Channel A or Channel B first.

Installing the DIMM Module

1. Make sure the PC and all other peripheral devices connected to it has been powered

down.

2. Disconnect all power cords and cables.

3. Locate the DIMM socket on the system board.

4. Push the “ejector tabs” which are at the ends of the socket to the side.

Note:

The system board used in the following illustrations may not resemble the actual

board. These illustrations are for reference only.

5. Note how the module is keyed to the socket.
