Which basic Infinity Fabric frequency for Ryzen 8400F

On one of the sites, I saw that the base frequency for it is 2400MHz, but I did not find official data. Comparing my performance in RAM performance tests, I found that at the same frequency of 5600MHz my performance is significantly lower than in the video. My mobo ASrock B650m-hdv m2, together with XMP, sets 2000MHz. If you manually specify 2400MHz, the tests become almost identical. Is the Infinity Fabric frequency at 2400MHz normal or standard?

The 8400F is similar to a 8600G but with the IGP disabled.

There was an early BIOS bug that defaulted Fabric to 2000MHz.

Update the BIOS and it should run 2400MHz.
