256GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit delivers 256GB across eight 32GB registered DDR5 modules running at 4800MHz with CL40 latency. ECC error correction and registered buffering provide the stability required for HP Z8 G5 and Z8 Fury G5 workstations handling mission-critical workloads.

Suited for HP Z8 G5 and Z8 Fury G5 upgrades

Workstations needing maximum registered ECC capacity for virtualisation, rendering or scientific computing will benefit. Systems that require unbuffered non-ECC memory, consumer motherboards or laptops cannot use these registered DDR5 RDIMMs.

Verify DDR5 RDIMM slot count and population rules

Confirm your workstation has eight available 288-pin DDR5 slots and consult the HP service guide for approved population order. Ensure the BIOS is current and that the platform supports 2Rx8 registered modules at 1.1V before installation.

Questions about this item

My HP Z8 G5 Fury G5 has four memory channels — will this 256 GB kit fill all eight 288-pin slots at once?

Yes, the kit provides eight 32 GB modules, one for every DDR5 RDIMM slot on the Z8 G5 Fury G5 motherboard.

I still have some DDR5 4800 1Rx8 modules — can I mix them with these 2Rx8 sticks?

Mixing ranks is not recommended; the Z8 G5 Fury G5 memory controller expects identical 2Rx8 modules for stable operation.

After installation, how do I confirm the system sees all 256 GB at 4800 MT/s with ECC active?

Open the BIOS or UEFI memory information screen — it should report 256 GB total, 4800 MT/s speed, CL40 timings and ECC enabled.
