8 GB DDR4 2666 MT/s SO-DIMM for Laptops

This single 8 GB DDR4 SO-DIMM runs at 2666 MT/s with a PC4-21300 bus speed. The 260-pin module is unbuffered and non-ECC, designed for laptop memory slots that accept DDR4 memory. It delivers up to 30% more bandwidth while reducing power consumption by up to 40% to extend battery life.

Suitable for single-slot 8 GB DDR4 upgrades

This module suits owners of compatible laptops that support 8 GB in a single DDR4 2666 MT/s SO-DIMM slot. Buyers who need ECC error correction or registered memory for workstation or server platforms should look elsewhere. It is also not for systems that require a different pin count or memory type than the 260-pin DDR4 standard specified.

260-pin DDR4 SO-DIMM form factor

The 260-pin SO-DIMM form factor is the specification that decides compatibility. Only laptops with DDR4 SO-DIMM slots keyed for 260 pins can accept this module. Verify the system manual or current memory configuration to confirm the slot type before purchase.

Questions about this item

Which capacity of this CT8G4SFS8266 module should I pick for a single-slot upgrade?

The module provides 8 GB in one SO-DIMM, so it fits a single DDR4 2666 MT/s slot and delivers the full 8 GB total capacity.

What does the 2666 MT/s rating mean once the module is installed in my laptop?

It runs at up to 2666 MT/s, giving up to 30% more bandwidth and faster burst access for improved sequential data throughput.

How does the 260-pin SO-DIMM interface limit performance in practice?

The 260-pin DDR4 SO-DIMM form factor caps the module at the PC4-21300 (2666 MT/s) standard, so it cannot exceed that bus speed.
