Maximizing Performance
Optimal configurations for highest performance:
T Matched, DDR400, Double-sided DIMMs
T Dual Channel Mode (Symmetrical DIMM population)
T Matched, DDR400, Dual Channel Mode
When not using DDR400, highest performing configuration:
T Symmetrical DIMM population with matched double-sided DIMMs
T Lightly loaded memory population aids in higher performance
T x8 Bus Width and lower DIMM cache latency also assists in higher performance
Dual Channel memory configuration provides higher performance than Single Channel configurations
Matched DIMMs need to have identical density, DRAM technology, DRAM bus width, and equal number of
memory banks
Optimal platform performance with Dual Channel, DDR400, matched DIMMs
T Fully loaded configurations can be single or double-sided DIMMs
T Lightly loaded configurations need to be double-sided DIMMs
When not using DDR400, best performance obtained with
T Symmetrical DIMM population and matched double-sided DIMMs
T Lightly loaded configuration
