Hi, I did a quick google and seems it was on the list previously but it was removed about 2 years ago.
Looks like a lot of people were having issues using it.
As the 5600X was removed from the list I would strongly suggest not to try use another version of ryzenmaster to OC.
So if you want to OC the 5600X, you would probably need to do it through the BIOS.
I'd recommend doing some further checks online about OC it in general just to see if there's any potential issues with that CPU.
