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.

■In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
