Certified Supermicro Server Memory

This 16 GB DDR4 module carries Supermicro certification for MEM-DR416LD-ER26 and uses Micron chips to deliver registered ECC reliability. It targets administrators upgrading or repairing validated Supermicro platforms that require registered DIMMs.

2666 MHz CL19 Registered ECC

The module runs at 2666 MHz (PC4-21300) with CL19 latency at 1.20 V, providing the exact registered ECC specification that decides compatibility. Dual-rank 2Rx8 organisation and 288-pin RDIMM form factor must match the motherboard's qualified-vendor list.

Fits Qualified Supermicro Slots

Installation requires an open 288-pin DDR4 RDIMM slot on a board that lists MEM-DR416LD-ER26 or MTA18ASF2G72PDZ-2G6E1 in its QVL. The registered buffer and ECC function free the memory controller from parity duties, but the module will not work in consumer desktop boards or unbuffered DIMM slots.

Questions about this item

What real-world speed does the 2666 MHz rating deliver in a server?

The module operates at 2666 MT/s with CL19 latency; actual data rate depends on the platform's memory controller and channel configuration.

How does the PC4-21300 designation limit bandwidth on a DDR4 system?

PC4-21300 certifies 2666 MT/s operation at 1.2 V; peak throughput is capped by the memory controller and number of populated channels.

Will the 288-pin RDIMM fit a standard DDR4 server DIMM slot?

Yes, the 288-pin registered form factor matches the DDR4 RDIMM socket used in compatible Supermicro and other server platforms.
