3. HARDWARE SETUP
3.5 System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Two sockets
are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random
Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory
size between 8MB to 1GB. One side (with memory chips) of the DIMM takes up one
row on the motherboard. This motherboard also supports NEC’s Virtual Channel
(VC) SDRAMs.
Memory speed setup is recommended through SDRAM Configuration under “Chipset
Features Setup”.
IMPORTANT (see General DIMM Notes below for more)
•
SDRAMs used must be compatible with current PC133 SDRAM specifica-
tion.
• DO NOT attempt to mix PC133 SDRAMs with VCM SDRAMs.

3. H/W SETUP
Install memory in any combination as follows:
DIMM Location 168-pin DIMM Total Memory
Socket 1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1

3.5.1 General DIMM Notes
• DIMMs that have more than 18 chips are not supported on this motherboard.
• For the system CPU bus to operate at
100
MHz/133MHz, use only PC100-/PC133-
compliant DIMMs.
• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32, 64,
128, 256, 512MB.
WARNING! Be sure that the DIMM you use can handle the specified SDRAM
MHz or else bootup will not be possible.
