This 24GB (3x8GB) RAM is 100% compatible with Fujitsu Primergy RX200 S6.

Information on memory configuration: The following technical specifications should be considered in advance: ECC DIMM (with Error-Correction-Code) or RDIMM (Registered DIMM) RAM can be installed in the device. RDIMM memory is recommended when large memory capacities are required. The different memory technologies (ECC / RDIMM) must not be mixed. If a memory upgrade is to be made with the already existing RAM, it must be checked which memory technology (ECC / RDIMM) is present. A higher memory clock of the memory module automatically adjusts to the memory clock specified by the system. This can especially be the case with larger capacities. Memory slots without a processor present must not be populated.

Technology GB / Module Count Total Maximum Capacity by Memory Technology UDIMM ECC 4GB RAM 12 48GB RDIMM 32GB RAM 12 384GB

Principles of memory configuration: The memory slots are organized in groups of 3. A maximum of 2 slots for UDIMM ECC memory can be used per group of 3. A maximum of 2 slots can be populated with 4Rank RDIMM memory per group of 3. The different groups of 3 slots do not need to have the same capacities.

Memory configuration for good system performance: Distribute the memory evenly across the memory slots and evenly across the CPUs. With 3 identical memories per group of 3 slots, performance can be up to three times faster compared to populating the group of 3 slots with only one memory. If more than one CPU is present, the RAM should be populated identically (mirrored to the other CPU) per CPU.
