NEMIX RAM 256GB DDR5 server kit

This 256GB kit contains sixteen 16GB DDR5 RDIMM modules rated at 4800MHz with CL40 latency. Each module is registered and includes ECC for data integrity in server environments. The kit operates at 1.10V and uses a 288-pin form factor. It is designed for Dell PowerEdge R760xd2 rack servers.

Suited for IT teams expanding Dell PowerEdge

The registered ECC design supports error correction and signal buffering required by enterprise workloads. Buyers needing unbuffered UDIMM modules for workstation or desktop boards should look at something else. Systems that cannot accept 1Rx8 registered DDR5 RDIMMs will not be compatible with this kit.

Check your server manual for supported DDR5 RDIMM

Verify that the platform accepts 1Rx8 registered modules at 4800MHz and that all sixteen slots can be populated simultaneously. Confirm the memory voltage requirement matches 1.10V. Ensure the BIOS version in use supports this capacity configuration before ordering.

Questions about this item

Does the server need a DDR5-compatible motherboard to use this 256 GB kit?

Yes, the modules are 288-pin DDR5 RDIMMs that require a DDR5 server platform with registered memory support.

Can I mix these 1Rx8 CL40 registered DIMMs with older registered DDR5 modules in the same Dell PowerEdge R760xd2?

Mixing ranks, latencies or voltages is not recommended; the system will default to the slowest common settings and may lose ECC integrity.

How do I confirm the full 256 GB is recognised and ECC is active after installation?

Enter the BIOS or run a hardware inventory tool — it should show 16 modules at 4800 MT/s, 1.10 V, with ECC status reported as enabled.
