3.5System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). Two sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory size between 8MB to 1GB. One side (with memory chips) of the DIMM takes up one row on the motherboard.

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

IMPORTANT (see General DIMM Notes below for more):

•SDRAMs used must be compatible with the current Intel PC133 SDRAM specification.

•DO NOT attempt to replace PC133 SDRAMs with VCM SDRAMs.•The motherboard only supports PC100 / PC133 DIMMsSDRAMs for system memory. Registered DIMMs are not supported.Install memory in any combination as follows:

DIMM Location	168-pin DIMM	Total Memory
Socket 1 (Rows 0&1)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1
Socket 2 (Rows 2&3)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1

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 at 100 MHz/133MHz, use only PC100-/PC133- compliant DIMMs.

•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.

WARNING! Be sure that the DIMM you use can handle the specified SDRAM MHz or else bootup will not be possible.
