3.5System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). Three sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of either 8, 16, 32, 64, 128, 256, or 512MB to form a memory size between 8MB to 1.5GB. 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.

To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip).

Memory speed setup is recommended through SDRAM Configuration in 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 SDRAMs with VC SDRAMs.Install memory in any combination as follows:

NOTES•DIMMs that have more than 18 chips are not supported on this motherboard.•For the system CPU bus to operate 100 MHz, use only PC100-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.
