Memory configuration:Our memory team will be happy to help you choose the right memory and configure your server.TechnologyGB /ModuleNumberTotalMaximum capacityRDIMM16GB RAM18288GBRDIMM32GB RAM12384GBUDIMM ECC memory and RDIMM (Registered) server memory cannot be used together. When upgrading, you should therefore know which memories are already available or upgrade completely to RDIMM memory.Principles of memory configurationThe memory slots are organised in groups of 3Per group of 3 only max. 2 slots for UDIMM ECC memoryPro group of 3 each only max. 2 slots 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 available can be used.Memory configuration for good system performanceDistribute the memories evenly among the memory slots and evenly among the CPUsWith 3 identical memories per group of 3 slots, the performance is up to 3 times faster than with a configuration of the 3 slots.If there is more than one CPU, the memories per CPU should be equipped identically (mirrored to the other CPU).
