BIOS isn't saving memory frequency?

Hello there,
Some time ago I posted my problem about framerates. I know what's the problem.
When I firstly launched my PC, I had to change memory's frequency (it was 2400MHz on default). I've set it to 3200MHz (bus speed of this memory)
Here are the specs:
Gigabyte B450 Aorus Elite (BIOS v. F42c)
HyperX Predator RGB 2x8GB 3200MHz
AMD Ryzen 7 2700 3.2GHz
MSI RTX 2060 Ventus OC 6GB
SilentiumPC Vero L2 500W
And what is my problem here? I guess BIOS isn't saving the frequency of memory.
So, firstly what I did I went to M.I.T tab, then selected Advanced Memory Frequency Settings, then picked Extreme Memory Profile (A.M.P), choosed Profile 1 (3200MHz), saved my settings and rebooted my PC.
My FPS haven't changed (also I've tried playing with 2400MHz and seen no difference), so I went back to bios and checked these settings, and... I was suprised! Settings were saved, but what attracted me was a simple tab showing frequency of RAM and CPU (sent a pick below, sorry for it being in Polish, I forgot to switch bios language), because it's saying (like shown in that picture) memory's speed is 2406.62MHz.
Any ideas what can cause it?

No, I didn't

How many Profiles are there in the Bios? You cant just pick any Profile that says 3200mhz. It must match the exact Memory you are using.

Disabled (2400MHz), Profile 1 (3200MHz), and Profile 2 (3000MHz, also tried this)

My Bios has dozens of Profiles i can choose from. Bios is difficult to help if you cant look at it yourself. I let you know if something comes to mind.
