3.5.1 General DIMM Notes
• When this motherboard operates at 100MHz, PC100-compliant modules must be
used because of the strict timing issues involved under this speed.
• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
• SDRAM chips are generally thinner with higher pin density than EDO (Extended
Data Output) chips.
• BIOS shows SDRAM memory on bootup screen.
3.5 System Memory (DIMM)
NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are
available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM) of 16, 32, 64, 128MB, or 256MB. Only single-sided 128MB
and double-sided 256MB DIMMs that use 128Mbit technology are supported by
this motherboard.
This chipset does not support ECC. However, ECC memory modules may still be
used, but the ECC function will not be available.
Memory speed setup is recommended through SDRAM Configuration in 4.4.1
Chip Configuration.
Install memory in any combination as follows:
Location 168-pin DIMM SDRAM Total Memory
DIMM1 Single-Sided
(Rows 0&1) Double-Sided x1
DIMM2 Single-Sided (must be occupied before DIMM3)
(Rows 2&3) Double-Sided (DIMM3 must be empty) x1
DIMM3 Single-Sided (DIMM2 must be single-sided)
(Rows 3&2) (Double-Sided DIMM cannot be used here!) x1
(must be same or half DIMM2 memory size)
Total System Memory (Max 512MB) =
