Table 132. Memory population rules (continued) Processor Configuration Memory population Memory population information B{12}, A{13}, B{13}, A{14}, B{14}, A{15}, B{15}, A{16}, B{16} traditional for 8 and 16 DIMMs installations for dual processor. ● Populate all the sockets with white release tabs first, followed by the sockets with black release tabs. ● Mixing of more than two memory module capacities in a system is not supported. ● Unbalanced or odd memory configurations results 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 Before working inside your system. 3. Remove the air shroud or remove the GPU 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.
