Supermicro Certified 16GB DDR4 RDIMM

This 16GB DDR4 2666MHz registered DIMM carries Supermicro certification and uses Micron chips. It is built for servers and workstations that require ECC error correction and registered signalling for stable operation under continuous load. The module runs at standard 1.20V with CL19 latency.

Registered ECC limits for DDR4 2666

Registered DIMMs add a buffer that reduces electrical load on the memory controller, allowing higher capacities per channel than unbuffered modules. ECC detects and corrects single-bit errors but cannot fix multi-bit failures. The DDR4 2666 standard caps the data rate at 2666 MT/s, so bandwidth is fixed by the specification.

Verify RDIMM support and slot layout

Confirm that your motherboard accepts DDR4 RDIMM modules and supports ECC Registered operation; some consumer boards only take unbuffered non-ECC memory. Check the qualified vendor list for the MEM-DR416L-CL03-ER26 part number and ensure enough 288-pin slots are free for the desired capacity.

Questions about this item

Should I pick the 16GB 2666MHz module or a different capacity for my Supermicro server?

This module provides 16GB at DDR4 2666MHz with CL19 latency. Choose it when your board lists PC4-21300 RDIMM support and you need a single 16GB stick.

What does the 2666MHz rating deliver once the DIMM is installed in a live server?

It runs at 2666MT/s with CL19 timing at 1.2V, giving 16GB of ECC registered bandwidth per slot.

Is the 288-pin RDIMM interface limited to a specific DDR4 speed ceiling in practice?

The 288-pin RDIMM form factor carries DDR4 2666 (PC4-21300) signals; the module itself is rated for 2666MT/s.
