This 64GB RAM is 100% compatible with the Dell Precision 5820 Tower (Intel Xeon CPU W-22xx).

Information on memory configuration: The following technical specifications should be observed in advance: RDIMM (Registered DIMM) or LRDIMM (Load Reduced DIMM) RAM memory can be installed in the device. LRDIMM memories are recommended if large memory capacities are to be achieved. RDIMM memory modules cannot be operated together with LRDIMM memories. If a memory expansion is to be carried out with the existing RAM memories, it must be checked which memory technology (RDIMM / LRDIMM) is available.
