carterauer, I do not think Ryzen Master (RM) disabled any of your cores. I suspect you did not do a fresh install of W10 and used an old copy. This is a short cut that saves a few minutes and creates a long list of hard to solve problems. Please install a fresh copy of W10, run RM and post a screenshot. Also list all your system specifications. Thanks and enjoy, John.
EDIT: If you have an old installation of W10, do not worry about msconfig or any other settings until you have done a fresh install of W10. The many and deep problems created by using an old copy of W10 cannot be corrected by changing a few settings.
