3.5System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.

This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM). One side (with memory chips) of the DIMM takes up one row on the motherboard.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1

Chip Configuration.Install memory in any combination as follows:

NOTE: Make sure the total installed memory does not exceeds 512MB. Otherwise, the system may hang during startup.

3.5.1 General DIMM Notes

•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.

NOTE: For PC133 SDRAM to run at 133MHz, the system CPU bus must also operate at that speed.
