3. H/W SETUP System Memory 3. HARDWARE SETUP 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 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). 3.5.1 SDRAM Configurations Technology Configuration Module 64Mbit 64Mbit 128Mbit 128Mbit 8M x 8 4M x 16 32M x 4 16M x 8 Single-Sided Double-Sided Single-Sided Double-Sided Single-Sided Double-Sided Single-Sided Double-Sided # Chips 8 or 9 (ECC) 16 or 18 (ECC) 4 8 16 or 18 (ECC) 32 or 36 (ECC) 8 or 9 (ECC) 16 or 18 (ECC) Memory (MB) 64 128 32 64 256 512 64 128 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. 24 ASUS CUC2000 User's Manual

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

(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.

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.
