The server board provides eight DIMM sockets across two branches, and each branch has two channels. Channel A consists of slots A1 and A2; channel B consists of slots B1 and B2; channel C consists of slots C1 and C2; and channel D consists of slots D1 and D2.

Figure 7. DIMM Configuration Diagram

DIMMs must be populated in pairs across consecutive channels starting with the lowest numbered slot in each channel. Slots A1 and B1 are paired, followed by slots C1 and D1. For performance reasons, when configuring four DIMMs, DIMM pairs A2 and B2 should never be populated before DIMM pair C1 and D1. A four DIMM configuration should be populated as A1 and B1; C1 and D1. See Figure 8 for a four DIMM configuration example.
