Table 72. Memory population rules Processor Memory population Memory population information Single processor A{1}, A{2}, A{3}, A{4}, A{5}, A{6}, A{7}, A{8}, A{9}, A{10}, A{11}, A{12}, A{13}, A{14}, A{15}, A{16} 1, 2, 4, 6, 8, 12 or 16 DIMMs are allowed. Dual processor (Start with processor1. Processor 1 and processor 2 population should match) A{1}, B{1}, A{2}, B{2}, A{3}, B{3}, A{4}, 2, 4, 8, 12, 16, 24 or 32 DIMMs are B{4}, A{5}, B{5}, A{6}, B{6}, A{7}, supported per system. B{7} A{8}, B{8}, A{9}, B{9}, A{10}, B{10}, A{11}, B{11}, A{12}, B{12}, A{13}, B{13}, A{14}, B{14}, A{15}, B{15}, A{16}, B{16} ● Populate all the sockets with white release tabs first, followed by the sockets with black release tabs. ● Unbalanced or odd memory configurations result in a performance loss, and the system may not identify the memory modules being installed. Always populate memory channels identically with equal DIMMs for best performance. ● Supported RDIMM configurations are 1, 2, 4, 6, 8, 12, or 16 DIMMs per processor. Removing a memory module Prerequisites 1. Follow the safety guidelines listed in the Safety instructions. 2. Follow the procedure listed in the Before working inside your system. 3. Remove the air shroud. WARNING: The memory modules are hot to touch for some time after the system has been powered off. Allow the memory modules to cool before handling them. Steps 1. Locate the appropriate memory module socket. 2. To release the memory module from the socket, simultaneously press the ejectors on both ends of the memory module socket to fully open. CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or metallic contacts. 3. Lift the memory module away from the system. Figure 59.
