2.System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of either 8, 16, 32, 64, 128MB, or 256MB to form a memory size between 8MB and 768MB. One side (with memory chips) of the DIMM 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 through “Chipset Features Setup” in BIOS setup.
Memory speed setup is recommended through SDRAM Configuration under “Chipset Features Setup” in BIOS setup.
IMPORTANT (see General DIMM Notes below)•To make using bus speeds ≥95MHz possible, SDRAMs used must be com- patible with the current Intel PC100 SDRAM specification..
Install memory in any combination as follows:DIMM Location |
| Total Memory | |
Socket 1 (Rows 0&1) | SDRAM 8, 16, 32, 64, 128, 256MB | x1 |

•At the time this User’s Manual was written, 256MB DIMMs are either available as registered memory or 128Mbit DIMMs.
•DIMMs that have more than 18 chips are not supported on this motherboard.
•For the system CPU bus to operate ≥95MHz, use only
•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.•
