DDR SDRAM provides 800 MBps or 1 GBps data transfer depending on

whether the bus is 100 MHz or 133 MHz. It doubles the rate to 1.6 GBps and

2.1 GBps by transferring data on both the rising and falling edges of the clock.

DDR SDRAM uses additional power and ground lines and requires 184-pin

2.5V unbuffered DIMM module rather than the 168-pin 3.3V unbuffered

DIMMs used by SDRAM.

Installation Procedure

You must install at least one memory

module in order to use the main-

board.

Note: You cannot use DDR

SDRAM and SDRAM

simultaneously.

Refer to the following to install the memory modules.

1. Push the latches on each side of the DIMM slot down.

2. Align the memory module with the slot. The DIMM slots are keyed with

notches and the DIMMs are keyed with cutouts so that they can only be

installed correctly.

3. Check that the cutouts on the DIMM module edge connector match the

notches in the DIMM slot:

4. Install the DIMM module into the slot and press it firmly down until it

seats correctly. The slot latches are levered upwards and latch on to the

edges of the DIMM.

5. Install any remaining DIMM modules.
