System memory
The motherboard has two Double Data Rate (DDR) DIMM sockets and
two Single Data Rate (SDR) DIMM sockets that supports up to 2GB non-
ECC PC2100/1600 DDR and PC133/100 SDRAM DIMMs.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.

1. A DDR or SDR DIMM is keyed with a notch so that it fits in only one
direction. DO NOT force a DIMM into a socket to avoid damaging
the DIMM.
2. DDR and SDRAM memory slots cannot be used simultaneously.
