resonator. n. 1. (Electronics) any body or system that displays resonance, esp a tuned electrical circuit or a conducting cavity in which microwaves are generated by a resonant current.. resonator-a hollow chamber whose dimensions allow the resonant oscillation of electromagnetic or acoustic waves. cavity resonator, resonating chamber. chamber-a natural or artificial enclosed space. soundbox, body-a resonating chamber in a musical instrument (as the body of a violin).
The other method of classifying the modules is by their bandwidth rating in megabytes per second. 1600MHz memory can run at a theoretically speed of 12.8 gigabytes per second or 12,800 megabytes per second.
The speed of the ram or frequency 1333MHz, 1600MHz etc represents speed of the memory with higher numbers there indicating greater data retrieval/throughput. Speed doesn't matter much in gaming, neither does CAS to an extent, a 1600MHz/CL9 is good for the job.
