2.System Memory (DIMM)

Only Dual Inline Memory Modules (DIMM) can be used with this motherboard. Sockets are available for 3.3Volt (power level) Unbuffered Synchronous DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB. One side (with memory chips) of the DIMM module takes up one Row on the motherboard.

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) and make the proper settings in the BIOS Chipset Features Setup. (NOTE: ECC is not available on the 440EX motherboard.)

IMPORTANT: Memory speed setup is required through "Auto Configuration" in BIOS Chipset Setup of the BIOS SOFTWARE.

WARNING: Memory modules must have 18 chips or less. Memory modules with more that 18 chips exceeds specifications and may cause unstable operation.

Install memory in any combination as follows:

ASUS Memory Examples:ECC EDO DIMM (9 chips) 72bitsNon-ECC SDRAM DIMM (8 chips) 64bitsGeneral DIMM Notes: (not true for all memory modules)

•Four possible memory chips are available: EDO or SDRAM with and without ECC.

•SDRAM chips are generally thinner with higher pin density than EDO chips.

•BIOS shows EDO or SDRAM memory on bootup screen.

•8 chip/side modules do not support ECC, only 9 chip/side modules support ECC.

•Single sided modules are usually 16 or 64 MB, double sided are usually 8, 32, or 128MB.
