2.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 either 8, 16, 32, 64, or 128MB to form a memory size between 8MB to 512MB or Extended Data Output (EDO) DRAM of either 8, 16, 32, 64, 128, or 256MB to form a memory size between 8MB to 1GB. One side (with memory chips) of the DIMM 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 through “Chipset Features Setup” in IV. BIOS SOFTWARE.

Memory speed setup is recommended through EDO Auto Configuration under “Chipset Features Setup”.

Install memory in any combination as follows:

DIMM Location	168-pin DIMM Memory Modules		Total Memory
Socket 0 (Rows 0&1)	SDRAM/EDO 8, 16, 32, 64, 128, 256MB	x1
Socket 1 (Rows 2&3)	SDRAM/EDO 8, 16, 32, 64, 128, 256MB	x1
Socket 2 (Rows 4&5)	SDRAM/EDO 8, 16, 32, 64, 128, 256MB	x1
Socket 3 (Rows 6&7)	SDRAM/EDO 8, 16, 32, 64, 128, 256MB	x1
	Total System Memory (Max 1GB)	=

ASUS Memory Modules

ECC EDO DIMM (9 chips) Non-ECC SDRAM DIMM (8 chips)

General DIMM Notes (not true for all memory modules)

•Four possible memory chips are supported: 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, 32, 64 or 128 MB, double sided are usually 8, 32, 64, 128 or 256MB.
