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 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.

General DIMM Notes
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 32, 64, 128, 256MB; double-sided come in 64, 128,
256, 512MB.
3. HARDWARE SETUP
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, DIMM0 DIMM2 DIMM1 DIMM3. Total memory size (in
MB), however, of DIMM1 and DIMM3 must not be greater than DIMM0
and DIMM2 (DIMM0 + DIMM2 DIMM1 + DIMM3).
WARNING!
Installing memory incorrectly may burn your memory modules. Make
sure that you follow the memory installation configurations on the next page.
