Capacity and Form Factor

This NEMIX RAM module delivers 32GB of DDR5 memory in a single 288-pin RDIMM. It operates at 4800MHz with a CAS latency of CL40 and runs at 1.1V. The 2Rx8 registered ECC design targets enterprise stability.

Compatibility Focus

This stick suits administrators upgrading HPE Z8 G5 or Z8 Fury G5 workstations that require registered ECC DDR5. Builders assembling custom desktops, consumer motherboards, or non-HPE servers should look elsewhere because the module is validated for those specific platforms.

Deciding Specification

The registered ECC RDIMM interface is the single factor that determines fit. Only systems designed for registered DDR5 ECC memory can accept this module; unbuffered or non-ECC platforms will not support it.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the memory slots in an HP Z8 G5 or Z8 Fury G5 workstation?

Yes, the module uses the standard 288-pin DDR5 RDIMM form factor that matches the DIMM slots on those HPE workstations.

What is the correct way to seat this registered ECC module so the system recognises the full 32 GB capacity?

Align the notch on the module with the key in the slot, press straight down until both retaining clips click, then verify in BIOS that the 2Rx8 rank and CL40 timings are detected.

When should I plan to replace this DDR5 ECC RDIMM in a continuously running server?

ECC modules like this 1.1 V CL40 part are rated for continuous operation; replace only if memory diagnostics report correctable errors exceeding the platform threshold.
