CT2K4G4SFS8266 Crucial 2x4GB DDR4 Unbuffered SO-DIMM RAM

High-Performance DDR4 SO-DIMM Memory Upgrade Kit optimised for mobile and SFF platforms with the CT2K4G4SFS8266

The CT2K4G4SFS8266 is a Crucial DDR4 SO-DIMM kit designed to stabilise and extend the usable service life of notebook and small form factor systems built on DDR4-era Intel and AMD client platforms. By providing 8GB total capacity across 2 matched 4GB modules, CT2K4G4SFS8266 supports predictable dual-channel memory behaviour where the host memory controller and motherboard topology allow it.

CT2K4G4SFS8266 operates at the JEDEC DDR4-2666 standard (PC4-21300S) with CL19 timing at 1.2V, aligning with OEM firmware defaults for broad compatibility and consistent boot behaviour. As a 260-pin, unbuffered, non-ECC SO-DIMM design, it targets client CPU memory controllers rather than server-class ECC platforms. In typical laptop and SFF configurations, the upgrade improves OS responsiveness, reduces paging to SATA/NVMe storage under multitasking, and provides a practical foundation for PCIe-attached storage and integrated GPU workloads that are memory-bandwidth sensitive.

Why Choose the CT2K4G4SFS8266?

The CT2K4G4SFS8266 delivers a balanced density-to-power profile for enterprise endpoints, enabling standardised fleet upgrades and spares stocking for DDR4 SO-DIMM systems. CT2K4G4SFS8266 is suited to controlled deployments where repeatable module characteristics, stable JEDEC operation, and low-voltage thermals support reliability across mixed notebook and compact desktop estates.

Crucial engineering focuses on compatibility-led validation and production consistency, aligning with modern IT lifecycle management requirements. With the CT2K4G4SFS8266, administrators can implement a uniform memory baseline that reduces configuration drift and simplifies maintenance across supported platforms.

Key Applications:

• Notebook RAM upgrades for corporate endpoints
• Small form factor PC refresh programs
• IT spares for DDR4 SO-DIMM fleet maintenance
