I have a AsRock fatal1ty X470 K4 mobo + Ryzen 7 3700X + Kingston HyperX Fury RGB 2x16GB sticks of RAM. (32GB at slots 2,4)

https://www.kingston.com/dataSheets/HX432C16FB3AK2_32.pdf

Mainboard has the newest 3.70 bios and I have loaded XMP profile 1 from bios (3200mhz)

Somehow CpuZ shows ram speed as 2400mhz?? (newest cpuz 1.91)
CpuZ dram frequency page shows ~1600 mhz (double data rate, i know = 3200mhz).

Is my ram speed actually 3200Mhz or that 2400mhz that the cpuZ´s main page reports??

My previous MSI AM4 mainboard had those same sticks and cpuz read ram speed correctly.
Can you share some info, thanks.
