To follow up, I've been testing for about 3 hours and after some additional settings in Ryzen Controller, I'm getting great performance and haven't had a single drop since the day after updating to BIOs 300.
Please excuse the garbage pics, didn't have much time lol.
Getting 80-100 fps in Madden 20 max settings and CPU temps that were previously reaching 87 degrees are steady at 70-75. Lowest clock speed is 1514 pretty rarely. Pretty consistently staying at 2675 to 2900. Thank you to everyone in this thread, I was about to return this and it's annoying to have to do work arounds but I can deal with this.
