[SOLVED] Why did the RAM with the declared frequency of 3200 in the BIOS in the DRAM FREQUENCY section show 2666?

I purchased a pc. I’m new in all this movement, but yesterday I decided to sit-down in the BIOS. I came across such a thing: RAM I have ADATA XPG 8x2 at a frequency of 3200 out of the box. But in the BIOS, dram frequency was set to 2666. I set it to 3200, but I don’t understand why the wrong frequency value was set from the very beginning, please help

2666 is the jedec spec. 3200 is xmp profile. you need to turn it on to use it

Ram starts at a base speed, something compatible that any cpu/motherboard configuration can get stable right out of the box. The 3200 is the xmp (eXtreme Memory Profile) setting, it's what speed the ram Can run at, not what it Will run at, until that option is chosen by you. It's basically a factory option overclock.
