Populating DIMM Sockets

The system will automatically operate in single channel mode, dual channel Asymmetric mode, or a higher-performing dual channel Interleaved mode, depending on how the DIMMs are installed.

■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 256MB DIMMS and Channel B is populated with one 512MB DIMM, the system will operate in Interleaved mode.

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