Overclocking DDR4 on Board A320, is it possible?

Hi all. Actually of the essence. Is the Asus Prime A320M-K and kit of DDR4 memory Kingston 2*4Gb 2400.
actually a subject
Even in the summer, I watched the video from channel Gecid, which stated that overclocking the RAM is possible even on the A320 chipset. Today I decided to try. And timings in DRAM Calculator calculated and tension and so forth. Put everything in the BIOS and the fee is away without any post codes. Well, okay. Resetting CMOS, I decided not to give up and put in BIOS only frequency, namely DDR4-3200... and it worked. In CPU-Z shows frequency 1596.2 then played DOOM and Overwatch about an hour and no freezes and stators, FPS grew. Is overclocking RAM so simple?
