Asus A7S266-VM/U2 - Manual (Page 20)

1-10 Chapter 1: Motherboard Information
1.8 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.
