3. HARDWARE SETUP
3.5 System Memory (DDR DIMM)
This motherboard uses only Double Data Rate (DDR) Synchronous Dynamic
Random Access Memory (SDRAM) Dual Inline Memory Modules (DIMMs).
DIMMs come in combinations of single or double-sided types ranging through 64MB,
128MB, 256MB, 512MB and 1GB to form a total memory size of 64MB to 3.5GB.
Each DIMM socket/module is two-sided: each side defines one “row” of memory.
DDR DIMMs support ECC and non-ECC modules; both types are available in
registered (for servers) and unbuffered (for PCs) versions:
~ Four (4) sockets are available for both 266MHz-PC2100 or 200MHz-PC1600
registered DDR DIMMs to form a memory size of 64MB to 3.5GB.
~ Two (2) sockets are available for 266MHz-PC2100 unbuffered DDR DIMMs:
to form a memory size of 64MB to 2GB.
NOTE: The DDR memory bus runs at the same frequency as the CPU front side bus.
