  • Total capacity16 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • 16 GB capacity lets workstations handle large datasets and virtual machines
  • ECC support detects and corrects single-bit errors for data integrity

  • Low 1.20 V operation reduces power draw and heat output

16 GB DDR4 ECC DIMM

Kingston 16 GB DDR4 2666 MHz CL19 ECC unbuffered DIMM is built for desktop systems that require error-correcting memory. It operates at 1.20 V with a 288-pin form factor and carries a lifetime limited warranty.

Registered ECC support required

The module uses unbuffered ECC DDR4 at 2666 MHz with CL19 latency. The motherboard must explicitly support unbuffered ECC DDR4; standard consumer boards without ECC capability will not use the error-correction function.

Suits workstations needing ECC

This suits builders assembling workstations or servers that list unbuffered ECC DDR4 in their qualified vendor list. It does not suit systems that only accept non-ECC memory or that require registered modules.

Questions about this item

Will the 2666 MHz speed run at that rate on my board?

The module is rated for DDR4-2666 (PC4-21300); the actual speed will match the highest DDR4 rate your motherboard and CPU support.

Is this a 288-pin DIMM and does it need registered slots?

Yes, it uses the standard 288-pin DDR4 DIMM form factor and is unbuffered, so it fits regular desktop DDR4 slots, not registered-only server sockets.

What are the physical dimensions for clearance?

The stick measures 5.3 inches long and 1.2 inches high, a standard full-height DDR4 DIMM profile.
