The final word on idle voltages for 3rd Gen ryzen

We have determined that many popular monitoring tools are quite aggressive in how they monitor the behavior of a core. Some of them wake every core in the system for 20ms, and do this as often as every 200ms. From the perspective of the processor firmware, this is interpreted as a workload that's asking for sustained performance from the core(s). The firmware is designed to respond to such a pattern by boosting: higher clocks, higher voltages.

By now, you may know that 3rd Gen Ryzen heralds the return of the Ryzen Balanced power plan (only for 3rd Gen CPUs; everyone else can use the regular ol' Windows plan). This plan specifically enables the 1ms clock selection we've been promoting as a result of CPPC2. This allows the CPU to respond more quickly to workloads, especially bursty workloads, which improves performance for you. In contrast, the default "Balanced" plan that comes with Windows is configured to a 15ms clock selection interval.

However, the latest version of AMD Ryzen Master can uniquely show you clocks and voltages in a cc6 state. No other tool can do it. Neat piece of info for the people looking to understand how their core behaves!
