Kingston Server Premier 16GB DDR4-2666 ECC — Registered RDIMM

The Kingston Server Premier 16GB DDR4-2666 (part number KSM26RD8/16HDI) is a registered, ECC 288-pin RDIMM for servers and workstations: a dual-rank (2Rx8) module running at 2666 MHz with CL19 timings at 1.2V, with on-board register buffering and error-correcting code for data integrity in mission-critical systems. Built to a fixed, validated BOM. Typically in stock with fast delivery across Cyprus.

Compatibility — check before buying:
This is a Registered DIMM (RDIMM) with ECC for SERVER and WORKSTATION motherboards only — it is NOT compatible with standard desktop boards, which require unbuffered (UDIMM) memory. It targets platforms such as Intel Xeon and AMD EPYC that support registered ECC DDR4-2666. Always confirm your server board and CPU support RDIMM, this rank (2Rx8) and 16GB modules on the vendor's memory QVL before ordering.

Key Features

 
ECC Error Correction
On-die and bus ECC detects and corrects single-bit memory errors on the fly, protecting data integrity for servers and workstations where uptime and accuracy matter.
 
Registered (Buffered) Design
A register buffers address and command signals, reducing electrical load so platforms can run more DIMMs per channel with stable signalling — essential for high-capacity servers.
 
DDR4-2666 CL19 (2Rx8)
This dual-rank x8 module runs at 2666 MHz (PC4-21300) on JEDEC timings at 1.2V, matching the validated speeds of Xeon and EPYC memory controllers that cap at DDR4-2666.
 
Server Premier Fixed BOM
Kingston Server Premier uses a fixed, validated BOM and rigorous testing for consistent quality and reliable server deployment and qualification.

Frequently Asked Questions

Can I use this in a normal desktop PC?
No. This is a Registered ECC RDIMM for server and workstation platforms only. Standard desktop motherboards require unbuffered (UDIMM) memory and will not POST with RDIMMs.
Which systems does it support?
Server and workstation platforms that support registered ECC DDR4-2666, such as Intel Xeon and AMD EPYC. Always check your server board's and CPU's memory QVL for RDIMM, 2Rx8 and 16GB module support.
What does 2Rx8 mean?
It describes the module's organisation: dual-rank (2R) using x8-wide DRAM chips. This layout is common on registered server memory and affects how many DIMMs and what capacities a platform supports.
Does ECC slow the system down?
ECC adds a negligible overhead in exchange for detecting and correcting memory errors. For servers and workstations, that data-integrity protection is well worth it.

Singular Expert Insight

Why this module
The Kingston Server Premier KSM26RD8/16HDI is a registered ECC DDR4-2666 RDIMM built for servers and workstations, not desktops — its buffered design and error correction keep high-capacity, always-on systems stable. It uses a fixed validated BOM for consistent qualification. Confirm your platform's QVL supports RDIMM, 2Rx8 and 16GB modules. For a standard desktop you need an unbuffered UDIMM instead, such as Kingston ValueRAM or FURY Beast DDR4; for entry servers using unbuffered ECC, a Server Premier ECC UDIMM is the alternative.

Buyer’s Guide

Buy it if
You are building or upgrading a server or workstation (Xeon/EPYC) that requires registered ECC DDR4-2666 memory and your platform QVL lists 2Rx8 16GB RDIMMs.
Skip it if
You have a standard desktop or gaming PC — those need unbuffered (UDIMM) memory and will not work with this registered ECC RDIMM.
Also consider
For desktops, the Kingston ValueRAM or FURY Beast DDR4 UDIMM; for entry servers, a Kingston Server Premier ECC unbuffered UDIMM.
