Single 64 GB LRDIMM for EPYCD8-2T

This NEMIX RAM module delivers 64 GB of DDR4 2933 memory in a single load-reduced DIMM. It is built for the ASRock Rack EPYCD8-2T motherboard and carries ECC protection for data integrity in server workloads. The 4Rx4 organisation and 1.2 V operation match the platform’s registered memory requirements.

4Rx4 rank layout

The 4Rx4 configuration is the decisive specification; the board’s memory controller expects exactly this rank arrangement for full-capacity operation. Using a different rank structure would prevent the system from recognising the full 64 GB. CAS latency is rated at CL21 at the rated 2933 MT/s speed.

No heat spreader or software bundle

The module ships without a heat spreader, relying on server chassis airflow for cooling. No software utilities or configuration tools are included; installation is a physical memory upgrade only. The package contains the single 288-pin LRDIMM ready for immediate installation.

Questions about this item

What does the 2933 MT/s rating mean once the module is installed in a compatible server?

The module runs at DDR4 2933 (PC4-23400) on the ASRock Rack EPYCD8-2T motherboard, delivering the rated throughput for server workloads.

How does the Load Reduced ECC interface affect usable bandwidth and error handling?

The LRDIMM buffer reduces electrical load on the memory controller while ECC corrects single-bit errors, enabling stable operation at 2933 MT/s with 4Rx4 organisation.

What physical slot and clearance does the 288-pin LRDIMM require?

It fits a standard 288-pin DDR4 DIMM slot and has no heat spreader, so it clears typical server CPU coolers and chassis airflow paths.
