SKU CH-B47F-JYBEC MPN KTL-TS426ES8/16G

16 GB DDR4-2666 ECC server memory module with CL19 latency for reliable data integrity

  • Rated speedDDR4 2666 (PC4 21330)
  • 16 GB DDR4-2666 capacity for high-density server workloads
  • ECC error correction protects data integrity in critical applications
  • Single-rank CL19 timing optimises latency at rated speed
  • Unbuffered DDR4 design simplifies installation in compatible platforms
  • Tested to PC4-21333 standard for reliable system compatibility

16 GB DDR4-2666 ECC module for servers

This single-rank module provides 16 GB of DDR4 memory with ECC error correction for server workloads. It operates at 2666 MHz with CAS latency 19 and runs unbuffered, making it suitable for compatible enterprise platforms that require registered data integrity.

Capacity and headroom for virtualization

The 16 GB capacity gives headroom for moderate virtualization hosts, database instances and multi-threaded applications. Workloads that scale beyond this single module will need additional DIMM slots populated to reach the platform's maximum supported memory.

Unbuffered ECC build with standard DDR4 pinout

The module uses an unbuffered signal design with on-die ECC, fitting standard DDR4 server slots without registered buffering overhead. Its single-rank layout keeps electrical loading low, allowing higher DIMM counts per channel where the platform permits.

Questions about this item

Will this DDR4-2666 ECC module run alongside older DDR4 ECC sticks in the same server?

The module operates at DDR4-2666 with CL19 latency. When mixed with slower DDR4 ECC memory, the system will typically clock all modules down to the lowest common speed and loosest timings.

How can I verify the ECC function is active after installing this 16 GB module?

Enter the server BIOS or UEFI and confirm that ECC is reported as enabled for the new DIMM. Operating-system tools such as dmidecode on Linux or Windows Management Instrumentation can also show the ECC status per module.

What comes in the box with this KTL-TS426ES8/16G module, and do I need any extra parts?

The package contains the single 16 GB DDR4-2666 ECC unbuffered DIMM. No cables, brackets or additional components are included; installation requires only a compatible DDR4 DIMM slot on the server motherboard.
