A-Tech Supermicro Certified 16GB DDR4 2666MHz ECC RDIMM 2Rx8 CL19 1.2V 288-Pin Server Memory

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.
