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.
3.5.1 SDRAM Configurations
Technology Configuration Module # Chips Memory
(MB)
64Mbit 8M x 8 Single-Sided 8 or 9 (ECC) 64
Double-Sided 16 or 18 (ECC) 128
64Mbit 4M x 16 Single-Sided 4 32
Double-Sided 8 64
128Mbit 32M x 4 Single-Sided 16 or 18 (ECC) 256
Double-Sided 32 or 36 (ECC) 512
128Mbit 16M x 8 Single-Sided 8 or 9 (ECC) 64
Double-Sided 16 or 18 (ECC) 128
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).
General DIMM Notes
• This motherboard only supports SPD DIMMs.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 32, 64,128MB; double-sided come in 64, 128, 256,
512MB.
