AMD Ryzen Master Application 
Once the system has rebooted back to the Operating System, AMD Ryzen Master is automatically 
launched. It is important to give the OS and AMD Ryzen Master a few moments to initialize after 
this step. Do not re-start AMD Ryzen Master manually or you will get the message that another 
instance of AMD Ryzen Master is already running, either the automatic one or the one you 
opened, and the second instance cannot start. 
The following screenshot shows the new default profile with six enabled cores and two disabled 
cores.
