AFOX 4GB DDR4 2666MHz Desktop RAM (AFLD44FK1P) - CL19, PC4-21300, LONG-DIMM

Give an ageing desktop a straightforward memory upgrade with this AFOX 4GB DDR4 2666MHz module, a budget-friendly way to keep everyday computing smooth and responsive. Whether your PC feels sluggish with too many browser tabs open or you're building a basic desktop from scratch, adding reliable DDR4 memory is one of the simplest ways to improve day-to-day performance.

This module runs at 2666MHz (PC4-21300 bandwidth) with a CL19 CAS latency, and uses the standard LONG-DIMM form factor for desktop motherboards. It's designed as a straightforward, no-frills memory upgrade rather than a high-end gaming or overclocking module, making it well suited to general office, browsing, and everyday desktop use. Adding extra memory capacity can meaningfully reduce slowdowns caused by a system running low on RAM, particularly when multitasking across several applications at once.
