You can use either ECC UDIMM or RDIMM memory.TechnologyGB /ModuleMemory SlotTotalMaximum capacity by memory technologyUDIMM ECC4GB RAM1248GBRDIMM16GB RAM18288GBUDIMM ECC memory and RDIMM (Registered) server memory cannot be used together. When upgrading, you should therefore know which memory is already available or upgrade completely to RDIMM memory.Memory configuration principlesThe memory slots are organised in groups of 3. 2 slots each for UDIMM ECC memoryPro group of 3 only max. 2 slots each for 4Rank RDIMM memoryThe different groups of 3 slots do not have to have the same capacitiesOnly the memory slots where the respective CPU is present can be used.Memory configuration for good system performanceDistribute the memories evenly across the memory slots and evenly across the CPUsWith 3 identical memories per 3-slot group, the performance is up to 3 times faster compared to a 3-slot configuration.If there is more than one CPU, the memories per CPU should be fitted identically (mirrored to the other CPU).
