System-specific DDR5 RDIMM kit

This NEMIX RAM kit supplies 512GB of DDR5 memory across eight 64GB registered DIMMs. It is built for the HP Z4 G5 workstation and operates at 4800 MT/s with CL40 latency. ECC and registered buffering are included for error correction and signal integrity in professional workloads.

Suited for memory-heavy workstations.

The modules target users who need maximum registered ECC capacity in the supported HP workstation. Systems that require unbuffered non-ECC DDR5 or that cannot address 512GB across eight slots should consider alternative configurations. Builders needing lower densities or different form factors will not be served by this kit.

Eight-module 512GB registered ECC capacity

The decisive specification is the 512GB total capacity delivered as eight 64GB 2Rx4 registered ECC RDIMMs at 4800 MT/s. This exact population and rank structure determines whether the workstation can accept the kit and reach the full memory limit.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the HP Z4 G5 workstation memory slots?

Yes, the kit is built as a direct 288-pin DDR5 RDIMM upgrade for the HP Z4 G5 workstation.

What is the correct order for populating the eight 64 GB modules during installation?

Follow the HP Z4 G5 service manual channel sequence; populate each channel evenly before adding a second rank.

How can I tell if one of the 64 GB modules needs replacement later?

Run a full memory diagnostic — ECC will log correctable errors, and persistent uncorrectable faults identify the failing stick.
