Functional Architecture
The following figure shows a dual channel configuration using three DIMMs. In this example,
the combined capacity of the two DIMMs in Channel A equal the capacity of the single DIMM in
the DIMM0 (blue) socket of Channel B.

Figure 6 shows a dual channel configuration using four DIMMs. In this example, the combined
capacity of the two DIMMs in Channel A equal the combined capacity of the two DIMMs in
Channel B. Also, the DIMMs are matched between DIMM0 and DIMM1 of both channels.
