Memory Modules (DIMM) slots, which supports PC2100/2700/3200 DDR SDRAM
modules up to 2GB. Install at least one DIMM module on the slots. Memory modules
can be installed on the slots in any order. You can install either single- or
double-sided modules to meet your own needs.

3. The plastic clip on each side of the DIMM slot will automatically close to hold the DDR
Modules in place.
