Speed DDR4 2666 (PC4 21300)

CAS Latency CL19

  • Faster data rates up to 2666 MT/s for responsive multitasking
  • Up to 30 percent more bandwidth improves throughput
  • Up to 40 percent less power draw extends battery life
  • CL19 timing at 1.20 V balances speed and efficiency
  • 260-pin SO-DIMM fits standard DDR4 laptop slots

8 GB DDR4 2666 SO-DIMM for laptop upgrades

This module adds eight gigabytes of DDR4 memory at 2666 MT/s to compatible notebooks. It uses the standard 260-pin SO-DIMM form factor and runs at 1.20 V. The unbuffered, non-ECC design suits mainstream consumer laptops that accept DDR4 SO-DIMMs.

Check slot count and maximum supported speed

Verify that your laptop has a free 260-pin DDR4 SO-DIMM slot and that its memory controller accepts 2666 MT/s modules. The stick operates at CL19 19-19-19 timings, so the system must be able to run at that latency. Confirm the platform does not require registered or ECC memory.

No extra accessories or software included

The package contains only the memory module itself. There are no brackets, adapters, driver discs or licence keys supplied. Installation is a hardware-only procedure: insert the SO-DIMM into the slot and secure it. Any performance gain comes from the extra capacity and DDR4 bandwidth increase.

I korthet

  • Faster data rates up to 2666 MT/s for responsive multitasking
  • Up to 30 percent more bandwidth improves throughput
  • Up to 40 percent less power draw extends battery life
  • CL19 timing at 1.20 V balances speed and efficiency
  • 260-pin SO-DIMM fits standard DDR4 laptop slots

Frågor om den här produkten

What comes in the box with the Crucial CT8G4SFRA266 8GB DDR4 2666 laptop RAM and do I need to buy anything else to install it?

The box contains a single 8GB 260-Pin DDR4 SO-DIMM module rated at 2666 MT/s with CL19 timings and 1.20V operation. No extra components are required for installation in a compatible laptop slot.

Should I choose this 8GB 2666 MT/s CL19 module or look for a different capacity or speed for my laptop?

Select this module if your laptop supports DDR4 SO-DIMM memory at 2666 MT/s and you need an 8GB upgrade. Match the existing memory speed and voltage (1.20V) for best compatibility; higher-speed modules will downclock to the system limit.

What does the 2666 MT/s rating mean for real-world performance once the module is installed in my laptop?

The 2666 MT/s rating indicates the maximum data transfer rate the module can sustain. In use, the memory controller sets the actual speed up to this limit, delivering up to 30% more bandwidth and up to 40% lower power draw compared with previous DDR generations.
