System memory
2.5.1 Overview
This motherboard uses only Double Data Rate (DDR) Synchronous Dynamic
Random Access Memory (SDRAM) Dual Inline Memory Modules (DIMMs).
These sockets support up to 3GB system memory using non-ECC , unbuffered
PC2700/PC2100/PC1600 DIMMs.
Each DIMM socket/module is two-sided: each side defines one "row" of
memory. DIMMs come in combinations of single or double-sided types
ranging through 64MB, 128MB, 256MB, 512MB and 1GB to form a total
memory size of 64MB to 3GB.
~ Three (3) sockets are available for both 266MHz-PC2100 or 200MHz-
PC1600 DDR DIMMs to form a memory size of 64MB to 3GB. Only two (2)
DIMMs will support 333MHz-PC2700; if more than two 333MHz DIMMs are
installed, the system automatically reverts to a maximum speed of 266MHz.

CAUTION!
DO NOT force a DIMM into a socket to avoid damaging the DIMM.
•
DIMMs with more than 18 chips are not supported.
•
ASUS motherboards support SPD (Serial Presence Detect)DIMMs.
This is the memory of choice for best performance vs. stability
•
BIOS shows DDR SDRAM memory on bootup screen.
•
This motherboard supports three pairs of differential clock signals
per DIMM.

DIMMs are keyed to fit into notches with only one direction.
