2. System Memory (DIMM)
Only Dual Inline Memory Modules (DIMM’s) can be used with this motherboard.
Three sockets are available for 3.3Volt (power level) Unbuffered Synchronous
DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB to form a
memory size between 8MB to 384MB. 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) which
makes 72bits (opposed to standard 64bits) and make the proper settings in the BIOS
Chipset Features Setup.
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 will cause unstable operation.
Install memory in any combination as follows:
DIMM Location 168-pin DIMM Memory Modules Total Memory
Socket 1 (Rows 0&1) SDRAM/EDO 8, 16, 32, 64, 128MB x1
Socket 2 (Rows 2&3) SDRAM/EDO 8, 16, 32, 64, 128MB x1
Socket 3 (Rows 4&5) SDRAM/EDO 8, 16, 32, 64, 128MB x1
Total System Memory (Max 384MB) =
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 or 64 MB, double sided are usually 8, 32, or 128MB.
ASUS Memory Examples:
ECC EDO DIMM (9 chips)
Non-ECC SDRAM DIMM (8 chips)
