Question What is my DRAM actually running at?

[SlamBeast]

My Bios is telling me one thing and CpuZ is telling me another.
x370-f
1700x
Corsair Vengeance pro 2x8 3200mhz

It is running at 3200 Mega transfers per second. Since it is "DDR" -- dual data rate RAM, a 1600 Mhz clock is used. The memory can transfer data twice per clock so 3200 Mt/s effective rate.

thank you. I was pretty confused.
