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 (1Gbit / 2Gbit) 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.
