III. INSTALLATION
General 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.
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.
ASUS Memory Examples:
ECC EDO DIMM (9 chips) 72bits
Non-ECC SDRAM DIMM (8 chips) 64bits
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 (only 440LX) SDRAM/EDO 8, 16, 32, 64, 128MB x1
Total System Memory (Max 384MB) =
