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. 

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.
