16GB DDR4 ECC UDIMM for Servers

This 16 GB DDR4 2666 module adds ECC error correction to compatible servers and workstations. The unbuffered DIMM runs at CL19 latency and 1.20 V standard voltage. A 2Rx8 rank layout and major-brand chips deliver dependable performance for memory-intensive workloads. It replaces Kingston KSM26ED8/16HD, KTD-PE426E/16G and related part numbers.

Check DDR4 288-pin slot and ECC support

Verify that your system accepts DDR4 UDIMM modules with ECC before ordering. The board must provide 288-pin slots and enable ECC unbuffered operation. Confirm the maximum supported speed and per-slot capacity in the system documentation. Mixing registered and unbuffered memory is not supported on the same platform.

Upgrades from lower-capacity or non-ECC DDR4

Replacing smaller DDR4 modules with this 16 GB stick increases total memory and adds error correction. The jump is worthwhile when applications hit capacity limits or data integrity matters. Systems already running at the maximum supported speed or rank count will not benefit further. Builders needing registered DIMMs or higher frequencies should look elsewhere.

Questions about this item

What comes in the box and do I need anything else to install it?

The box contains one 16 GB DDR4 2666 ECC UDIMM module. No extra parts are required; the DIMM plugs directly into a 288-pin DDR4 slot.

I see several Kingston part numbers listed; which one should I match to my system?

Match your system's qualified vendor list against any of the listed Kingston part numbers — KSM26ED8/16HD, KSM26ED8/16MR, KTD-PE426E/16G, KTH-PL426E/16G or KTL-TS426E/16G — they are all compatible equivalents for this module.

What does the PC4-21300 rating mean for actual throughput in my server?

PC4-21300 is the JEDEC designation for DDR4 2666, specifying the module's peak data rate of 21300 MT/s under standard 1.20 V operation.
