What this module is

This is a 16 GB DDR4 2666 MHz ECC registered DIMM built with major-brand chips on a 288-pin form factor. It runs at 1.2 V with CL19 latency and a 2Rx8 organisation for server and workstation platforms.

Who it suits and who should look elsewhere

It suits administrators upgrading Kingston KTH-PL426D8/16G, KSM26RD8/16HCI, KTL-TS426D8/16G, KSM26RD8/16MEI, KTD-PE426D8/16G or KSM26RD8/16HAI part numbers in compatible systems. Builders needing non-ECC unbuffered memory or a different speed grade should look elsewhere.

How it fits into a build

The module plugs into a standard DDR4 288-pin registered DIMM slot and draws 1.2 V at the rated frequency. It frees capacity headroom for virtualisation or database workloads while leaving other memory channels available for further expansion.

Questions sur cet article

Does my server need a registered DIMM slot and ECC support to run this 2666 MHz CL19 module?

Yes — the module is a registered ECC RDIMM, so the motherboard must accept registered DDR4 DIMMs and have ECC enabled in the BIOS for it to function.

Will the 2Rx8 organisation of this stick work in a channel that currently uses 1Rx4 modules?

The 2Rx8 rank layout is independent of the existing 1Rx4 modules; the memory controller treats each rank separately, so the stick can share a channel as long as the platform supports mixed-rank populations.

How do I confirm the module is running at 2666 MT/s with CL19 timings after installation?

Check the BIOS memory information screen or a utility such as CPU-Z; it should report DDR4-2666, CL19-19-19 and 1.20 V for the installed module.
