Figure 3: Dual-channel symmetric and asymmetric mode

– The maximum performance can be achieved in a symmetric dual-channel

configuration. Therefore both channels have to be populated with the same

amount of memory. The DRAM device technology (1 Gbit / 2 Gbit / 4 Gbit)

may vary from one channel to the other.

– If the amount of memory differs between the two channels, the system board

will run in dual-channel asymmetric mode.

– Regardless of the mode, all DIMMs will run at the highest common

frequency that is allowed by the SPD Data of the DIMMs and the maximum

speed of the selected configuration.

– Single-channel mode is used when 1 memory module is populated in

DIMM 1A.
