DDR4 4000Mhz running at 1200Mhz? Pulling hair out :(

I have the MSI GodLike X570 mobo with AMD Ryzen 3950x CPU.

I had 16GB of HyperX Predator DDR4 RGB 16GB Kit of 2 (2 x 8GB) 4000MHz CL19 DIMM XMP RAM Memory with Infrared Sync Technology (HX440C19PB3AK2/16).

All was fine with the world... Windows showed memory running at 2000Mhz.

Now, I bought 32GB of TEAMGROUP T-Force Dark Za (Alpha) 32GB Kit (2x16GB) DDR4 Dram 4000MHz (PC4-32000) CL18 Desktop Memory Module Ram for AMD Ryzen TDZAD432G4000HC18LDC01.

Now, it's showing memory running at 1200Mhz... WTF



Am I missing something? Did I buy the wrong RAM? Should I do something in the BIOS? I don't need to overclock anything but would definitely love to max out the STOCK speeds of the sticks

Make sure you have XMP/DOCP enabled in the BIOS.

Will do. There's XMP 1 and 2. Which one should I choose?

Either setting will be an OC. When you choose one, it will show you the frequency or timing changes in BIOS, so choose whatever you are comfortable with.

For more infor (and a chart for each XMP profile for each RAM type) go here: https://www.intel.com/content/www/us/en/gaming/xmp-for-core-processors.html
