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 first number, xxx, indicates the maximum clock speed that the memory chips support. For instance, DDR400 memories work at 400 MHz at the most, DDR2-800 can work up to 800 MHz, and DDR3-1333 can work up to 1,333 MHz. It is important to note that this is not the real clock speed of the memory. The real clock of the DDR, DDR2, and DDR3 memories is half of the labeled clock speed. Therefore DDR400 memories work at 200 MHz, DDR2-800 memories work at 400 MHz, and DDR3-1333 memories work at 666 MHz. The second number indicates the maximum transfer rate that the memory reaches, in MB/s.
