A-Tech 4GB DDR4 2666MHz CL19 1.2V Desktop RAM

SKU CH-46N0-TSD7F

4GB DDR4 2666MHz CL19 1.2V desktop memory module with 288-pin DIMM form factor

  • Capacity4GB
  • SpeedDDR4 2666 (PC4 21300)
  • Tested Frequency2666
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCNo
  • 4GB capacity lets you run more applications at once
  • DDR4 2666 MHz speed moves data quickly through the system
  • CL19 CAS latency keeps response times tight for everyday tasks
  • 2 V operation reduces power draw and heat output
  • 288-pin DIMM fits standard desktop motherboard slots

Capacity and Compatibility

This module provides 4 GB of DDR4 memory in a single 288-pin DIMM. It is built as a direct replacement for Crucial CT4G4DFS8266 and CT2K4G4DFS8266 parts and is tested for AMD and Intel desktop platforms.

Interface Limits

The stick runs at 2666 MHz with a CAS latency of 19 at the standard 1.2 V. As an unbuffered non-ECC DIMM it follows the PC4-21300 specification and will operate at the highest common speed the motherboard and CPU memory controller allow.

Installation Notes

Align the notch with the slot key and press firmly until the retention clips click; the 288-pin layout fits standard desktop DDR4 sockets only. Common issues include mixing modules with different latencies or voltages, which can prevent the system from posting, and forgetting to seat the module fully on both ends.
