3.5 System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Four 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 2GB. 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 and Enhanced Memory System’s High-speed DRAMs (HSDRAMs).
Memory speed setup is recommended through 4.4.1 Chip Configuration.
IMPORTANT (see General DIMM Notes below for more)
• SDRAMs used must be compatible with the current Intel PC133 SDRAM
specification.
• DO NOT attempt to mix registered SDRAMs with VC SDRAMs.
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
Socket 3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 4 (Rows 6&7) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1

General DIMM Notes
• DIMMs that have more than 18 chips are not supported on this motherboard.
• For the system bus to operate at
100
MHz, use only PC100- or PC133-compliant
DIMMs; for the system bus to operate at 133MHz, use PC133-compliant DIMMs.
• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
• SDRAM chips are generally thinner with higher pin density than EDO (Extended
Data Output) chips.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 16, 32, 64,128, or 256MB; double-sided come in 32,
64, 128, 256, or 512MB.
