Supermicro Certified 16GB DDR4 Server Memory

This A-Tech module delivers 16GB of DDR4 2666MHz ECC registered memory in a single 288-pin RDIMM. It is built for servers and workstations that require error correction and registered buffering for data integrity. The dual-rank 2Rx8 organisation with CL19 latency operates at the standard 1.2V DDR4 voltage. Supermicro certification confirms compatibility with qualified platforms.

DDR4 2666 Registered ECC Limits

Registered DIMMs add a clock cycle of buffering, so they cannot be mixed with unbuffered modules on the same channel. ECC functionality only activates when the platform chipset and BIOS support it; otherwise the module runs as non-ECC. The PC4-21300 rating defines the maximum standard bandwidth; faster speeds require platform overclocking support which most servers disable. Population rules may restrict rank count per channel.

Verify Platform Before Ordering

Confirm that your motherboard or server accepts DDR4 RDIMMs and supports 2Rx8 registered modules at 2666MHz. Check the vendor memory qualification list for the exact Supermicro part number MEM-DR416L-HL03-ER26 or the Hynix HMA82GR7AFR8N-VK equivalent. Ensure the CPU and chipset provide ECC capability if error correction is required. Validate maximum capacity per slot and total channel population limits.

Preguntas sobre este artículo

Should I choose the 16GB single module or add multiple sticks to reach my server's capacity?

This listing is a single 16GB DDR4 2666MHz RDIMM. Add identical modules to fill your board's slots and reach the total memory your workload requires.

What does the 2666MHz rating deliver inside a live server?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency, giving registered ECC bandwidth suited for multi-threaded server workloads at standard 1.2V.

How does the 288-pin RDIMM interface affect what the system can use?

The 288-pin RDIMM form factor with registered ECC 2Rx8 organisation fits DDR4 server boards that support registered memory; it will not work in unbuffered desktop slots.
