Targeted upgrade kit

This 64 GB kit contains four 16 GB DDR5 4800 registered ECC RDIMMs built for the HP Z4 G5 workstation. The modules run at 1.1 V with CL40 latency and use 288-pin packaging. IT professionals who manage fleets of compatible HPE systems receive a validated, stress-tested solution.

Capacity and headroom

The 64 GB total (4 x 16 GB) provides ample headroom for virtualization, large datasets and multi-application workloads on supported platforms. Memory-intensive tasks such as rendering or database caching benefit from the registered buffer and ECC protection. Systems that require more than four DIMM slots or higher densities will need a different configuration.

Thermals, noise and power draw

Operating at 1.1 V, the modules draw minimal power and run without heat spreaders in the workstation's managed airflow. No active cooling is present on the DIMMs themselves, so acoustics depend entirely on the system fans. Registered buffering adds negligible overhead to the platform's overall thermal envelope.

Questions sur cet article

Will these 4800 MT/s DDR5 ECC RDIMMs run with the 1Rx8 modules already in my Z4 G5?

Yes — the kit is 4×16 GB DDR5 4800 CL40 1Rx8 registered ECC, matching the workstation's supported memory type and rank structure.

How can I verify the 64 GB kit is running at 4800 MT/s with ECC active after install?

Open BIOS or your OS memory utility; it should show 64 GB total, 4800 MT/s speed, CL40 timings, 1.10 V, and ECC enabled for each 288-pin DIMM.

Does the MR38400-618K4 package include only the four 16 GB RDIMMs or any extra parts?

The box contains the four 16 GB DDR5 4800 ECC RDIMMs and nothing else; no heat spreaders, cables or tools are included.
