The system will automatically operate in single channel mode, dual channel Asymmetric mode,
or a a higher-performing dual channel Interleaved mode, depending on how the DIMMs are
installed.
To identify the operating mode, run Computer Setup and select the System Information menu
item. The operating memory mode will appear in the line showing the system total memory.
The system will operate in single channel mode if the DIMM sockets are populated in one
channel only.
The system will operate in dual channel Asymmetric mode if the total memory capacity of
the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in
Channel B.
The system will operate in a higher-performing dual channel Interleaved mode if the total
memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the
DIMMs in Channel B. However, the technology and device width can vary between the
channels, For example, if Channel A is populated with two 256 MB DIMMS and Channel B
is populated with one 512 MB DIMM, the system will operate in Interleaved mode.
