Frequency and timings. Key indicators of memory speed. The higher the memory frequency, the better. However, chase frequency to the detriment of the timings does not make sense (and Vice versa). The choice of frequency is possible from DDR4 2133 4800. Frequencies above 4000 are available as a rule only on certain motherboards and overclocking with selected modules (as well as a good memory controller, which can like). Good frequency in overclocking is 3200, above can above only selected modules (they will be a separate section).Platform AM4 RAM frequency is particularly important, because it is tied to the internal data transmission bus Infinity Fabric (running at half the frequency of RAM). The fact that these multi-core processors consist of two modules with multiple cores that communicate with each other via a bus called Infinity Fabric – and it is more effective the faster you RAM. The frequency effect in the first place, but it is not the only factor.In this regard, a very desirable modules that acceleration can reach even 3200 frequency, while the frequency Infinity Fabric will be already fully meet the needs of the processor. Frequencies above also raise productivity but require large voltage, the best motherboard and memory selection. The increase from 3200CL14 -> 3466CL14 there, but usually so time consuming that does not cover the costs of its achievement. Although now the situation is better and many of Hynix\Toshiba can take 3200\3333 on AM4, B-die, works steadily for 3466-3533-3600.
The same memory at lower timings (at one frequency) will be more effective. Ie 3200CL14 > 3200CL16, as an example.
In General, the timings will be added in a separate section. The main so-called "primary" timings (CAS...) give a performance. Twisting the secondary and tertiary timings, it is possible to "get" another 5-7% performance.
