  • ECC protection prevents data corruption in server workloads
  • 16 GB capacity handles multi-tasking and heavy applications
  • 2666 MHz DDR4 speed delivers high data throughput
  • CL19 19-19-19 timing optimises latency for responsiveness
  • 20 V low voltage reduces power draw per module

Server DDR4 16 GB Module

This 16 GB DDR4 module is built for servers, workstations and compatible motherboards that require ECC memory. It operates at 2666 MHz with CL19 latency and 1.20 V voltage. The unbuffered, dual-rank design targets administrators who need error-correcting capacity for stable workloads.

DDR4 2666 Interface Limits

The 288-pin DDR4 interface runs at 2666 MHz (PC4-21300) with CL19 timing, setting the maximum bandwidth and latency envelope for this module. Unbuffered signal processing means the memory controller drives the bus directly, so platform support for unbuffered ECC DIMMs is required. No heat spreader is fitted, leaving thermal management to chassis airflow.

16 GB Capacity and Headroom

A single 16 GB stick adds substantial capacity for multi-tasking, high-resolution image editing and 3D rendering workloads. Dual-rank organisation (2Rx8) helps populate rank-limited slots efficiently. Systems needing more than 16 GB per channel or registered ECC modules will require different memory.

Questions about this item

Should I choose the 16GB module or look for a different capacity?

This listing is for a single 16GB DDR4 module. If your server or workstation has free 288-pin slots and supports unbuffered ECC memory, adding one 16GB stick increases total capacity by that amount.

What does the 2666 MHz rating mean once the module is installed?

The module runs at up to 2666 MHz (PC4-21300) when the platform supports that speed. If the motherboard or CPU memory controller is limited to a lower rate, the module will downclock automatically to match.

Is this DDR4 ECC module registered or unbuffered, and what does that limit?

It is an unbuffered (UDIMM) ECC module with a 2Rx8 organisation. It fits standard 288-pin DDR4 slots that accept unbuffered ECC memory; it will not work in slots that require registered (RDIMM) or load-reduced (LRDIMM) modules.
