256GB DDR5 ECC RDIMM kit for HP Z4 G5

This 256GB kit contains four 64GB DDR5 4800 CL40 registered DIMMs with ECC. It is built for the HP Z4 G5 workstation and suits professionals who need large, error-corrected memory capacity for stable compute workloads.

Tool-less DIMM installation with population rules

The modules slot into the 288-pin DDR5 sockets without tools. Installation is straightforward, but the workstation requires registered ECC RDIMMs populated in supported configurations; mixing unbuffered or non-ECC DIMMs will prevent boot.

256GB registered ECC capacity for heavy workloads

Four dual-rank 64GB modules deliver 256GB at 1.1V, providing headroom for virtualization, large datasets and multi-application sessions. The registered design supports this density, though the platform's maximum supported memory per channel ultimately limits further expansion.

商品問答

Will the HP Z4 G5 POST and show 256 GB at DDR5 4800 CL40?

After installing all four modules, enter the BIOS or UEFI; it should report 256 GB total, DDR5 4800 speed, and CL40 latency with ECC active.

What ships in the kit and what must I source separately?

The box contains four 64 GB DDR5 4800 CL40 2Rx4 ECC RDIMM modules (1.10 V, 288-pin). No cables, tools, or heat spreaders are included.

Should I choose this 256 GB kit or a smaller capacity for the Z4 G5?

Select the 256 GB (4 × 64 GB) kit when the workload needs maximum registered ECC capacity; choose a lower-capacity kit if 256 GB exceeds the application requirement.
