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.
