Support for memory frequencies by the processor and motherboard?

Question

Computers

There is an Intel Core i5 3330 processor (supports 1600 memory frequency) and a motherboard that supports 1866 frequency.
Question: does it make sense to put 1866? Or will there be no performance increase?

Answer 1

Looking for what purpose to assemble a computer. If an ordinary development machine, then it is unlikely. The gain will be only in tests that are critical for memory bandwidth, for example, in Linpack.
It is advisable to take a faster memory only when the additional payment is 5 dollars. Because otherwise you can get the required 1866 MHz by overclocking, because the chips, as a rule, for 1600 / 1866 of the same manufacturer are the same :)

Answer 2

It does not, since everything will work at the maximum frequency of the slowest element, that is, a 1600 processor.

Answer 3

In your case, there is no point in high-speed memory. This is pure overclocking, and if you do not drive and optimize the rest of the system parameters (bus, timings, multiplier, etc.), the gain will be lost in errors. In addition, high-speed modules often have increased timings.
