The minimum memory upgrade increment is two DIMMs per branch. The DIMMs must cover the same slot position on both channels. DIMMs pairs must be identical with respect to size, speed, and organization. DIMMs that cover adjacent slot positions do not need to be identical.
When adding two DIMMs to the configuration shown in Figure 13 (above), the DIMMs should be populated in DIMM sockets C1 and D1 as shown in the following diagram. Populated DIMM sockets are shown in Grey.

Figure 14. Recommended Four DIMM Configuration
Functionally, DIMM sockets A2 and B2 could also have been populated instead of DIMM sockets C1 and D1. However, your system will not achieve equivalent performance. Figure 13, on the previous page, shows the supported DIMM configuration that is recommended because it allows both branches to operate independently and simultaneously. FBD bandwidth is doubled when both branches operate in parallel.
