8 GB DDR4-2666 module

This Samsung DDR4 DIMM delivers 8 GB of capacity at 2666 MT/s with a PC4-21300 rating. It suits mainstream desktop builds that need reliable standard-speed memory for everyday workloads. Buyers who require higher capacities or faster JEDEC speeds should look elsewhere.

Thermals noise and power draw

Standard DDR4 modules run passively without fans so they add no audible noise inside the chassis. Power consumption stays within normal JEDEC limits for DDR4-2666 operation. Heat output is modest and handled by ordinary case airflow.
