32 GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 32 GB of DDR5 4800 registered ECC memory in two 16 GB modules. It is built for the Dell Precision 5860 tower workstation and operates at 1.1 V with CL40 latency. The 288-pin RDIMM format ensures signal integrity for professional workloads.

Suited for Precision 5860 upgrades

The kit suits IT professionals expanding memory in a Dell Precision 5860 for ECC-dependent tasks such as scientific computing or virtualization. It is not for consumer desktops or laptops that require unbuffered non-ECC DDR5. Buyers needing higher capacity per module or faster speeds should look elsewhere.

Simple DIMM installation

Installation follows the workstation manual: power down, open the chassis, align the 288-pin modules with the DDR5 slots, and press until the latches click. No heat spreader is present, so airflow over the bare PCB is required. Common issues include mixing registered and unbuffered DIMMs or populating slots in the wrong order.

Questions about this item

Do I need a motherboard with 288-pin DDR5 RDIMM slots to use this memory kit?

Yes, this kit uses 288-pin DDR5 RDIMM modules that require a compatible motherboard with registered DIMM slots supporting DDR5 4800 (PC5-38400) at 1.10V.

Will these CL40 1Rx8 modules work if I keep my existing DDR5 4800 ECC RDIMMs in the other channels?

Mixing ranks or latencies can cause instability; for best results populate all channels with identical 1Rx8 CL40 modules or follow the Dell Precision 5860 memory configuration guide.

How can I verify the kit is running at DDR5 4800 with ECC active after installation?

Check the system BIOS or UEFI memory information screen — it should report 4800 MT/s, CL40, 1.10V, and ECC enabled for each installed 16 GB module.
