System Memory; General Dimm Notes - Asus CUV4X-E - CUV4X-E User Manual

3. HARDWARE SETUP

3.5 System Memory

This motherboard uses only Dual Inline Memory Modules (DIMMs). Four DIMM
sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic
Random Access Memory (SDRAM) of 16, 32, 64, 128, 256, 512MB, or 1GB densities
for a system memory configuration of 32MB up to 1.5GB. One side (with memory
chips) of the DIMM takes up one row on the motherboard. This motherboard also
supports NEC's Virtual Channel SDRAMs and Enhanced Memory System's High-
speed DRAMs.
IMPORTANT (see General DIMM Notes below for more)
• SDRAMs used must be compatible with the current Intel PC133 SDRAM
specifications.
• DO NOT attempt to mix registered SDRAMs with VCM SDRAMs.
Install memory in any combination as follows:
DIMM Location
Socket 1 (Rows 0&1)
Socket 2 (Rows 2&3)
Socket 3 (Rows 4&5)
Socket 4 (Rows 6&7)

3.5.1 General DIMM Notes

• DIMMs that have more than 18 chips are not supported on this motherboard.
• For the system CPU bus to operate
compliant DIMMs.
• ASUS motherboards support Serial Presence Detect (SPD) 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.
• Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32, 64,
128, 256, 512MB.
WARNING!
Make sure that the DIMM you use can handle the specified SDRAM
speeds, otherwise the computer does not boot.
