  • Capacity16GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • TimingCL 19
  • Voltage1.20V
  • ECCNo
  • 16GB capacity for smooth multitasking
  • 2666MHz DDR4 speed delivers responsive performance
  • CL19 latency ensures efficient data access
  • 2V operation reduces power consumption
  • Dual-rank x8 design optimises memory bandwidth

Product Identity

This Samsung DDR4 module provides 16GB of unbuffered desktop memory operating at 2666MHz with a CAS latency of 19. The dual-rank x8 design runs at a standard 1.20V, making it a straightforward upgrade for compatible motherboards.

Suitability

This module suits builders adding a single 16GB stick to a DDR4 system that accepts CL19 unbuffered UDIMMs. Buyers needing ECC error correction, registered buffering, lower latency timings, or higher frequency ratings should look at other options.

Deciding Specification

The PC4-21300 speed rating confirms the 2666MHz data rate, which is the single figure that determines whether this module matches your motherboard's supported memory specification.

Preguntas sobre este artículo

Will the 16GB DDR4 module need any firmware updates or component replacements during its service life?

The memory has no firmware and no moving parts, so it does not require updates or scheduled component replacements.

What limit appears first when the 2666MHz kit runs at full load for extended periods?

The JEDEC-rated 1.20V voltage ceiling is reached before thermal or timing limits become an issue.

How much heat and noise does the 1.2V unbuffered DIMM produce during all-day operation?

It runs silently with no fan, and the low 1.2V supply keeps heat output minimal inside the case.
