4 DIMM DDR4 frequency with Ryzen 9 5900X

At what frequency will the 4x16GB 3200MHz RAM with the Ryzen 9 5900X processor on the Asus ROG Crosshair VIII Hero (sAM4, X570) motherboard work?

The 4x16GB 3200MHz RAM will work at 3200MHz with the Ryzen 9 5900X processor on the Asus ROG Crosshair VIII Hero (sAM4, X570) motherboard.

This is because the Ryzen 9 5900X processor officially supports up to 3200MHz DDR4 memory.

However, it is important to note that this is just the official support speed. Some Ryzen 9 5900X processors may be able to run RAM at higher speeds, but this will depend on the individual processor's memory controller. If you want to try running your RAM at a higher speed, you can enable XMP (Extreme Memory Profile) in your motherboard's BIOS.

XMP is a memory profile that is stored on the RAM modules themselves, and it contains the optimal settings for running the RAM at a higher speed.

I saw information about the frequency support of the memory controller implemented in processors of the Ryzen family and it indicated that with 4 DIMM Dual Rank the memory will operate at a frequency of 1866 MHz. Is this true?002.jpg
