This 8GB memory is 100% compatible with Dell XC730. The following technical specifications should be considered in advance: RDIMM and RDIMM 3DS (Registered DIMM) or LRDIMM and LRDIMM 3DS (Load Reduced DIMM) RAM memory can be installed in the unit. LRDIMM memories are recommended when large memory capacities are to be achieved. RDIMM and RDIMM 3DS memory modules cannot be operated mixed together with LRDIMM and LRDIMM 3DS RAM. If a memory expansion is to be carried out with the already existing RAM memories, it must be checked which basic memory technology (RDIMM / LRDIMM) is available. If memory modules are offered with higher clock rates than specified by the system, the memory clock is automatically adjusted to the system specifications.
