The mainboard accommodates two memory modules. You
must install at least one module in any of the three slots. Each
module can be installed with up to 1 GB of memory; total
memory capacity is 2 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:
