Recently, I've purchased a Ryzen 3700x processor, where I'm coming from an older 1700. I upgrated my Asrock Fatal1ty x370 Gaming X mobo to the latest BIOS (ver 6.00) which you can find here

On Linux, everything works flawlessly. The only weird thing I could've find is that when you query cpu's capabilities:

- 'lscpu' gives: CPU max MHz 5224.2178 (which is incorrec)
- 'lshw -c cpu' gives 5.2GHz (incorrect)
- 'dmidecode -t processor' shows 4.4Ghz instead!! (which is correct)

Right now, when I watch for frequencies, they are normal (from 2.2Ghz to 4.2Ghz) when I compute via OpenMP or just on gaming.

I checked P-States via script and these are right, from 2.2Ghz to 3.6Ghz.

So the question is: how come it marks 5.2GHz as the maximum frequency? Is it just a minor bug?

The feeling I got tells me that I don't have to care, but I ask you cos' you maybe saw something related to this issue.

Thanks in advance. Greetings
