384GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit provides 384GB of DDR5 memory across twelve 32GB registered DIMMs. It operates at 4800 MT/s with CL40 latency and 1.10V voltage. The modules use 2Rx4 organisation and include on-die ECC for data integrity in server and workstation environments.

For Dell Precision 7960 Workstations

The kit is validated for the Dell Precision 7960 Rack and Tower Workstations. It suits administrators expanding memory capacity in those specific platforms. Builders using other motherboards or consumer chipsets should verify qualified vendor lists before purchase because registered ECC RDIMMs require platform support.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC correction handles single-bit errors without halting the system. The 1.10V operating voltage keeps power draw stable across long compute jobs in the supported Dell Precision 7960 configurations.

Questions about this item

Does my Dell Precision 7960 need any specific firmware or BIOS setting to recognise 12 × 32 GB DDR5 4800 CL40 ECC RDIMMs?

The kit is built for the Precision 7960 rack and tower workstations, so the system BIOS should detect the 384 GB capacity at 4800 MT/s once all twelve modules are seated.

Can I mix these 2Rx4 DDR5 4800 CL40 RDIMMs with other DDR5 ECC registered modules already installed in my Precision 7960?

Mixing ranks, speeds or CAS latencies can prevent the memory controller from training correctly; for reliable operation populate all twelve slots with identical 32 GB 2Rx4 CL40 modules.

After installation, how can I confirm the full 384 GB is running at DDR5 4800 with ECC active?

Check the system BIOS or UEFI memory information screen — it should show 384 GB total, 4800 MT/s speed, CL40 timings and ECC enabled for each of the twelve 288‑pin RDIMMs.
