3.5System 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 Access Memory (SDRAM) of 64, 128, 256, or 512MB with Serial Presence Detect (SPD).

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.

IMPORTANT:

1.This motherboard’s chipset only supports 64Mbit and 128Mbit SDRAMs (see SDRAM Configurations).

32Mx4 128 Mbit support is for registered DIMMs only. 4Mx16 64 Mbit support is for unbufferred DIMMs only.

2.If more than one socket will be populated with DIMMs, the socket closer to

the processor must be populated with a higher-sized DIMM (in MB). For

example, DIMM1 DIMM3 DIMM2 DIMM4. Total memory size (in MB), however, of DIMM2 and DIMM4 must not be greater than DIMM1 and DIMM3 (DIMM1 + DIMM3 DIMM2 + DIMM4).
