16GB DDR4 ECC RDIMM kit for servers

This 16GB kit contains two 8GB DDR4 2666MHz ECC Registered DIMMs built for servers and workstations. The modules run at 1.2V with CL19 latency and a 2Rx8 dual-rank organisation. They are designed to improve loading times, system responsiveness and multi-tasking capacity in compatible enterprise platforms.

Check your platform supports DDR4 Registered ECC

Only systems that accept DDR4 Registered ECC DIMMs can use this memory; desktop and laptop boards will not work. Consult your system manual for supported speeds, maximum capacity per slot and the correct slot-population rules for dual-channel operation before ordering.

Dual-channel kit simplifies installation

The matched pair enables dual-channel bandwidth when installed in the correct slots, reducing the chance of mismatched timing issues. All modules receive the manufacturer’s quality-assurance testing, and the kit is backed by a lifetime warranty with US-based technical support available for compatibility questions.

Questions about this item

What comes in the 16GB kit and is anything else required?

The kit contains two 8GB DDR4 2666MHz ECC Registered DIMM modules (2Rx8, CL19, 1.2V). No extra components are needed; install both modules into compatible server or workstation DIMM slots.

Should I choose this dual-rank kit or a single-rank alternative?

This 2Rx8 dual-rank kit provides 16GB across two modules, which many server chipsets prefer for maximum capacity per channel. Choose it when your system supports dual-rank Registered DIMMs and you want the full 16GB in a matched pair.

What does the 2666MHz rating deliver in an actual server?

The modules run at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V, giving standard server bandwidth and error-corrected throughput for workloads that require registered ECC memory.
