The problem with the selection of RAM, how to understand this problem?

Question

motherboards

The problem is that I bought a mat. board MSI H61M-G35 / G3 with a declared maximum frequency of 1333 MHz, but at that time I did not know this and bought it at a frequency of 1600 MHz, it works at a frequency of 1600 MHz, I checked it in all programs (CPU-Z, AID64) feels great. how so??? checked the information about the mother. Why is the maximum 1333 declared on the board of the officials, but it works without problems at 1600, while it is displayed everywhere, now I'm afraid to buy the same die suddenly something goes wrong. and how to do it right?
