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.
CPU memory type. No, that's just the speed it officially supports. Faster memory is considered overclocking, but it works just fine way above 2133. The CPU is also compatible with DDR3 memory, but officially only at a voltage of 1.35V. Again, higher voltage isn't ruled out, but if it fries the memory controller it's not Intel's responsibility.
