HP ProLiant DL380 Gen9 server memory

This 64 GB kit supplies four 16 GB DDR4 registered ECC DIMMs that are validated for the HP ProLiant DL380 Gen9 platform. Each module runs at 2133 MHz with CL15 timing at 1.2 V. The registered design and 2Rx4 organisation match the server’s 12 DIMM slots per CPU and support the maximum 1.5 TB per processor.

Thermals and power in normal operation

Registered DDR4 modules at 1.2 V draw modest power during typical server workloads. Without a heat spreader the chips rely on the chassis airflow that the DL380 Gen9 provides. Acoustic contribution is negligible because the memory itself has no moving parts.

Behaviour under sustained load

When all 48 DIMM sockets are populated across four CPUs the memory controllers clock the modules to optimal speeds for the installed processor mix. The ECC and registered buffering maintain data integrity during continuous operation. Mixing registered and load-reduced DIMMs is not supported, so this kit must populate only RDIMM slots.

Questions about this item

How do I install these 288-Pin DDR4 DIMMs in the DL380 Gen9 and which slot order avoids the common mistake?

Shut down the server, open the chassis, and insert each 16 GB module into the 12 slots per CPU following the numbered sequence in the ProLiant QuickSpecs; the step most people miss is populating the first processor's eight slots before adding any to the second CPU.

What maintenance or replacement will this 64 GB ECC Registered kit need during its service life?

No routine maintenance is required; if a module fails the lifetime warranty from Computer Memory Solutions covers replacement, otherwise the kit runs until a capacity upgrade is desired.

What is the first limit reached under sustained load with these 2133 MHz CL15 modules?

The memory controller clocks the kit down to the highest speed supported by the specific processor and module count installed, so the effective bandwidth ceiling appears before thermal or voltage limits.
