System Memory 3. H/W SETUP
NOTE: At the time this User’s Manual was written, 256MB DIMMs are only avail-
able as Double-Sided registered memory. Using 2x2x2 SDRAM can greatly improve
the onboard graphics’ performance.
3.5.1 General DIMM Notes
• 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 (Ex-
tended Data Output) chips.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,
128, 256MB.
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.
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) =
