3.5System Memory

This motherboard supports either Double Data Rate (DDR) and Single Date Rate (SDR) Dual Inline Memory Modules (DIMMs).

Two DDR DIMM sockets are available for 2.5V (power level) DDR Synchronous Dynamic Random Access Memory (DDR SDRAM) of 64, 128, 256, 512MB, or 1GB densities for a system memory configuration up to 2GB.

Three SDR DIMM sockets are also onboard for 3.3V unbuffered SDRAM of 64, 128, 256, 512MB, or 1GB densities for a maximum system memory of 3GB.

WARNING! Do not mix DDR DIMMs and SDR DIMMs. Mixed configurations do not work on this motherboard.

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 200MHz/266MHz, use PC1600-/PC2100- compliant DDR DIMMs.

•ASUS motherboards support Serial Presence Detect (SPD) DIMMs. This is the memory of choice for best performance vs. stability.

•BIOS shows SDRAM memory on bootup screen.
