Hello,
You should be able to just use the Power Plans features for a basic limiter.
Here's a short quote from the foot note on the use of Ryzen Master, "AMD does not provide support or service for issues or damages related to use of an AMD processor outside of official AMD specifications or outside of factory settings. You may also not receive support or service from your board or system manufacturer. Please make sure you have saved all important data before using this overclocking software."
