3.HARDWARE SETUP

3.5System Memory (DDR DIMM)

This motherboard uses only Double Data Rate (DDR) Dual Inline Memory Modules (DIMMs). Two sockets are available for 2.5Volt (power level) unbuffered/registered Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM) of 64MB, 128MB, 256MB, 512MB, 1GB to form a memory size between 64MB to 2GB. One side (with memory chips) of the DIMM takes up one row on the motherboard.

DDR DIMMs support both ECC (Error Correction Code, typically used in servers) and non-ECC (used on desktops/laptops) and are available in both registered (typi- cally used in servers) and unbuffered (typically used in PCs) versions.

NOTE: The DDR memory bus runs at the same frequency as the CPU front side bus.
