The mainboard accommodates two SDR SDRAM and two
DDR SDRAM modules. You must install at least one module
in any of the four slots. Each module can be installed with up
to 1 GB of memory; total memory capacity is 4 GB.
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:
