  • 20V operation reduces power draw per module
  • Validated for ASRock Rack EPYCD8-2T motherboards

Server ECC LRDIMM upgrade

This NEMIX RAM module delivers 64GB of DDR4 2666 ECC Load Reduced memory in a single 288-pin LRDIMM. It operates at 1.2V with CL19 latency and a 4Rx4 rank structure using major OEM DRAM. The kit targets administrators expanding ASRock Rack EPYCD8-2T platforms.

Platform slot and rank limits

Verify that your motherboard accepts 4Rx4 Load Reduced DIMMs at the DDR4 2666 data rate and that the memory controller supports the total capacity you intend to install. Check the vendor documentation for maximum per-slot density and population rules before ordering.

Single-module simplicity

The package contains one 64GB LRDIMM with no heat spreader, allowing direct installation into an available slot. No additional cables, brackets or software licences are included, so the upgrade is limited to the memory capacity itself.

Questions about this item

Does the package include only the 64GB DDR4 2666MHz ECC LRDIMM module or are extra parts needed?

The box contains one 64GB DDR4 2666MHz PC4-21300 CL19 288-pin ECC LRDIMM module; no additional components are required for installation.

When should I choose the 64GB 4Rx4 LRDIMM over a smaller registered DIMM for my ASRock EPYCD8-2T?

Choose this 64GB 4Rx4 load-reduced module when the platform needs maximum capacity per slot and the memory controller supports LRDIMM topology.

What does the PC4-21300 rating mean once the module is installed in the server?

PC4-21300 confirms a 2666 MT/s data rate at 1.2 V with CL19 latency, delivering the rated throughput when the motherboard runs the memory at its native speed.
