Ram frequency (?)

Hi there!

 

Out of curiosity, I opened up CPU-Z earlier today, and noticed that my ram frequency was only at 1600mhz:

However-  I know for a fact that in my bios I set the ram to 3200mhz.

Also the latency doesn't make sense, where it should have been CL16 ( 16-18-18-36). 

 

Memory:

Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz C16 Desktop Memory Kit – White (CMK16GX4M2B3200C16W)

 

Rest of system specs:

Asus ROG Strix X570-E gaming

AMD Ryzen 5 3600

GeForce RTX 2070 Super

 

So - is CPU-Z wrong? When I open Ram Cache, I do see it does recognize it can run at a max of 3200mhz:

Or is something else going on?

 

I appreciate your input! :)

DDR means the data rate is doubled over actual operating frequency, so you are running 3200.

DDR means Double Data Rate, so the frequency will be double what CPU-Z displas.
