64 GB DDR4-2666 LRDIMM for dense server builds

This SK hynix module delivers 64 GB of DDR4-2666 memory in a 288-pin load-reduced DIMM. It targets administrators who need to maximise installed capacity on platforms that support LRDIMM technology. The registered buffer and ECC protect data integrity in virtualization, HPC and in-memory database workloads.

Verify LRDIMM support and avoid mixing with UDIMMs

Confirm the motherboard and CPU memory controller accept load-reduced DDR4 modules before ordering. ECC UDIMMs and ECC registered DIMMs cannot be mixed; all existing UDIMMs must be removed if this module is installed. The system must also be a server platform, as these modules are not compatible with standard desktop boards.

Sustained operation at 1.20 V

The load-reduced architecture lowers the electrical load on each channel, allowing more DIMMs per channel while maintaining 2666 MT/s throughput. CAS latency of 19 and 1.20 V operation keep power draw predictable during extended virtualization or big-data runs. No heat spreader is fitted, so chassis airflow must handle the thermal load.

Questions about this item

What comes in the box with this HMAA8GL7AMR4N-VK module and is any extra hardware needed?

The listing supplies the single 64GB 288-pin DDR4 LRDIMM; no cables, brackets or additional components are included and none are required for installation in a compatible server slot.

Should I choose this 64GB LRDIMM or a smaller registered DIMM for my Supermicro single-socket blade?

Pick this 64GB load-reduced module when you need to exceed the per-channel rank limit of standard RDIMMs; it lets you populate more slots per channel for higher total capacity.

What does the 2666 MT/s rating mean once the DIMM is running in a live server?

The module transfers data at 2666 million transfers per second at CL19 latency and 1.20 V, delivering PC4-21300 bandwidth while the load-reduced buffer reduces electrical load on the memory controller.
