This 48GB (3x16GB) RAM is 100% compatible with the Fujitsu CELSIUS R570 (D2628).

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 for achieving large memory capacities. The different memory technologies (ECC / RDIMM) must not be mixed. If a memory expansion is to be made with the 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 should not be populated.

Technology GB / Module Count Total Maximum Capacity by Memory Technology:

• UDIMM ECC 8GB RAM 648GB
• RDIMM 16GB RAM 696GB
• RDIMM 32GB RAM 6192GB

Principles of memory configuration: The memory slots are organized in groups of 3. In each group of 3, a maximum of 2 slots can be used for UDIMM ECC memory. In each group of 3, a maximum of 2 slots can be populated with 4Rank RDIMM memory. 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 memory modules 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 module. If more than one CPU is present, the RAM should be populated identically (mirrored to the other CPU) per CPU.
