Server memory kit for Dell PowerEdge R530

This 64GB kit contains four 16GB DDR4 registered DIMMs that run at 2133MHz with CL15 timing. It is built for the Dell PowerEdge R530 and other compatible Dell servers that require ECC registered memory. The modules operate at 1.2V and use a 288-pin form factor.

Registered ECC with x4 organisation

Each module is a 2Rx4 registered ECC DIMM, providing error correction and signal buffering for stable server operation. The kit delivers 64GB total capacity across four sticks, matching the system's requirement for matched modules within each memory bank. Mixing registered and unbuffered ECC is not supported by the platform.

Straightforward DIMM installation

Installation follows standard 288-pin DIMM insertion into the server's memory slots. The system supports up to 192GB with 16GB modules or 384GB when 32GB modules are released. Care is needed: 4GB registered ECC modules exist in x4 and x8 variants that must not be mixed within the same bank, though this kit uses uniform 16GB x4 parts.

Questions about this item

Will the 288-pin registered DIMMs need any periodic maintenance inside a Dell PowerEdge R530?

No routine maintenance is required for the memory modules themselves; they are solid-state components with no moving parts.

What limit appears first when the kit runs continuously at DDR4-2133 CL15 in a Dell PowerEdge R530?

The platform caps total registered ECC memory at 192 GB with 16 GB modules, or 384 GB once 32 GB modules are released.
