I followed just about every tutorial I could find.. using Ryzen Master I have no issues overclocking to 4.2ghz. When doing the settings in the bios I can barely get it to post and it never boots into windows. Ram is Samsung B die 3200mhz I use XMP profile mode that is an option and it works fine from what I can tell. I had to end up clearing CMOS to get back into windows.
