Why is my RAM speed lower than advertised?

[deuceAE12]

I have 32 Gbs of DDR4 advertised at 3200 MHz but when in task manager, it is displaying as only being 2400MHz. I just built this PC, did I do something wrong? and how can I fix it?

 

Here is some details about my set up

RAM: TEAMGROUP T-Force Delta RGB DDR4 32GB (2x16GB) 3200MHz (PC4-25600) 

Motherboard: ASROCK B450 GAMING ITX/AC

CPU: AMD AMD RYZEN 5 3600

You have to turn on XMP in the bios

Or it could be because of your motherboard RAM speed limit

Or DOCP, since it's AMD.

I wonder what the percentage is of people running their 3000+ MHz ram at 2133 or 2400, because they didn't know you have to enable something in the BIOS to actually get the advertised clocks?

I’m pretty sure this was in the Cyberpower PCs that LTT and GN tested, neither of them had had XMP enabled and had performance impacts.

Probably everyone who buys prebuilts.

I meant more people slapping PCs together without much knowledge, but for a prebuilt to come this way is criminal. That's crazy.
