EDIT: sorry if I chose the wrong category but I heard this is considered overclocking ...

Hi.
After a year of having my PC, I realized that my RAM (RAM DDR4 16GB Kit (2x 8) PC4-25600 3200MT/s CL16 SR x8 1.35V Crucial BX Sport LT) has only a speed of 1200MHz.
I realized I could use some A-XMP profiles so I choose Profile 1


Now, according to Task Manager and CPU-Z, my frequency is around 1600MHz.


My motherboard is TOMAHAWK B450 MAX and CPU Ryzen 3600
  1. is using A-XMP safe in my case?
  2. and why is frequency 1600MHz and not 3200MHz, am I doing something wrong? (EDIT: is it because it is dual channel?)
Thank you!

^^ What he said.

Because the memory controller will transfer data on the rising of the clock signal and the falling of the clock signal, the DRAM 'actual' frequency in your case is 1600 mhz while the 'effective' rate is double that - 3200mhz.

Thank you. Is everything above that I did fine and safe? Is there something I should be careful about? Is this considered as overclocking?
