NEMIX RAM 512GB DDR5 ECC RDIMM Kit

This 512GB kit contains eight 64GB DDR5 4800 registered ECC modules built for the Dell Precision 7875 workstation. It targets IT professionals and power users who need maximum registered memory capacity for demanding server-class workloads. The modules operate at 1.1V with CL40 latency and use major OEM chips from Samsung, Micron or Hynix.

Straightforward DIMM installation

The 288-pin DDR5 RDIMMs insert into the workstation's memory slots like standard DIMMs, but the registered buffer requires the platform's memory controller to support registered operation. Mixing these registered modules with unbuffered DIMMs will prevent the system from posting. Always populate slots in the order specified by the Dell Precision 7875 service manual to ensure proper channel interleaving.

Verify Precision 7875 memory population rules

Confirm the workstation's maximum supported capacity per socket and the required DIMM population sequence for eight modules. The system must support 2Rx4 registered DDR5 at 4800MT/s and 1.1V operation. Check that the current BIOS version recognises 64GB registered density, as older firmware may limit usable capacity per slot.

Questions about this item

How can I verify the kit is running at the advertised 4800 MT/s and CL40 latency after installation?

Open the system BIOS or UEFI and confirm the memory speed reads 4800 MT/s with timings showing CL40; the registered ECC modules will also report their 2Rx4 organisation and 1.10 V voltage there.

What exactly ships in the box and do I need any extra brackets or cables for the Dell Precision 7875?

The package contains eight 64 GB 288-pin DDR5 RDIMM modules for a total of 512 GB; no additional brackets, cables or heat spreaders are required for the Precision 7875 DIMM slots.

The listing shows a single 512 GB kit (8 × 64 GB). Are there smaller capacity kits for the same workstation?

This specific part number MR38400-924K8 is only offered as the 512 GB eight-module kit; other capacities would carry different part numbers and are not included in this listing.
