128GB DDR4 2933 ECC RDIMM kit

This NEMIX RAM kit provides 128GB of DDR4 memory across two 64GB registered DIMMs. It operates at 2933MHz with CL21 latency and 1.2V power draw. The modules use 4Rx4 organisation and ECC error correction for data integrity in Dell Precision 5820 tower workstations.

Suits IT teams expanding Precision 5820 capacity

The 288-pin RDIMM form factor and registered design match Dell Precision 5820 requirements. ECC support protects critical workloads from silent data corruption. Buyers needing non-ECC UDIMMs for consumer motherboards or higher-frequency modules for overclocking should look elsewhere.

Two matched 64GB modules in the box

The kit includes a pair of tested 64GB sticks so dual-channel operation is ready immediately. No heat spreaders are fitted, keeping the modules low-profile for dense server chassis. No software, drivers or additional accessories are bundled with this memory upgrade.

Questions about this item

Does this kit require a Dell Precision 5820 workstation to operate?

Yes, the 128GB DDR4 2933 CL21 ECC RDIMM kit is validated for the Dell Precision 5820 Tower Workstation.

Can I mix these 4Rx4 registered modules with older unbuffered DDR4 DIMMs already in the system?

No, registered ECC RDIMMs cannot be mixed with unbuffered memory; all slots must use registered modules for the workstation to boot.

How do I confirm the 128GB kit is running at 2933 MT/s with ECC active after installation?

Enter the system BIOS or use a tool like CPU-Z to verify the memory speed reads 2933 MT/s and ECC status shows enabled.
