Dual Channel Guidelines
Matched DIMM configuration in each channel
!"
Same Density (128MB, 256MB, 512MB, 1GB, etc.)
!"
Same DRAM technology (128M-bit, 256M-bit, or 512M-bit)
!"
Same DRAM bus width (x8 or x16)
!"
Both either single-sided or dual-sided
Matched in both Channel A and Channel B memory channels
!"
Populate symmetrical memory slots
Optimal platform performance with Dual Channel, DDR400, matched DIMMs
!"
Fully loaded configurations can be single or double sided DIMMs
