Server-ready 64 GB DDR4 kit

This 64 GB kit contains four 16 GB registered ECC DIMMs built for HP ProLiant DL120 Gen9 and ML110 Gen9 servers. Each module runs at DDR4-2133 with CL15 timing at 1.2 V. The registered design and error-correcting code protect data integrity in multi-socket configurations.

Steady throughput under load

Registered buffering reduces electrical load on the memory controller so all eight slots per processor can be populated without signal degradation. ECC corrects single-bit errors on the fly, preventing silent corruption during long compute jobs. Modules clock down automatically to match the installed processor’s supported speed.

Replaces smaller RDIMM sets

The kit upgrades systems running 8 GB or 16 GB RDIMMs toward the 256 GB registered maximum. It is not for boards that accept only unbuffered UDIMMs or that forbid mixing RDIMM and LRDIMM types. Buyers needing more than eight DIMMs per CPU must install a second processor.

Questions about this item

How much power do the 1.2 V registered DIMMs draw when the ProLiant runs 24/7?

Each module operates at 1.2 V DDR4 voltage; total system draw depends on the number of populated slots and the processor's memory controller, so consult the server's power calculator for exact watts.

What must already be in the server for this 4-stick kit to work?

The kit requires an HP ProLiant DL120 Gen9 or ML110 Gen9 with a supported processor installed; if only one CPU is fitted, only eight DIMM slots are available, so verify CPU count before populating.

Can these 2133 MHz CL15 RDIMMs share slots with slower DDR4 modules already in the ProLiant?

Memory will clock down to the lowest common speed supported by the processor and module mix; mixing RDIMM and LRDIMM is not supported, so all installed sticks must be registered ECC DIMMs.
