128GB DDR4-2666 ECC LRDIMM

This 128GB DDR4-2666 ECC LRDIMM is built for servers that need maximum memory capacity per slot. It targets administrators expanding virtualisation hosts or database nodes where registered, load-reduced modules are required. The module uses major-brand DRAM and matches Dell part SNP917VKC/128G for drop-in compatibility.

DDR4-2666 registered limits

The DDR4-2666 interface caps transfer rate at 21300 MB/s per module and operates at 1.2V with CL15 latency. Registered buffering and 8Rx4 organisation reduce electrical load on the memory controller, allowing higher densities than standard RDIMMs, but the bus speed remains fixed at 2666 MT/s regardless of CPU capability.

Check slot count and LRDIMM support

Verify that your server motherboard accepts 288-pin DDR4 LRDIMMs and supports 8Rx4 ranks at the intended population density. Some platforms limit the number of load-reduced modules per channel or require specific BIOS revisions to recognise 128GB density. Confirm the memory-configuration rules for your exact model before ordering.

Questions about this item

Should I choose the 128GB 8Rx4 module or a lower-capacity alternative?

The 128GB 8Rx4 LRDIMM maximises installed memory per slot, letting you reach higher total capacity on platforms that support load-reduced modules.

What does the DDR4-2666 rating mean for actual server performance?

DDR4-2666 (PC4-21300) delivers 2666 MT/s data transfer, reducing latency for virtualisation and database workloads when paired with a compatible CPU memory controller.

How does the 288-pin DDR4 interface limit speed or capacity in practice?

The 288-pin DDR4 interface caps this module at 2666 MT/s; higher speeds require a newer memory generation, while total capacity depends on your motherboard's maximum supported memory per slot.
