Correct Power Plan for Ryzen 3000 CPU's

>>>>TL : DR <<<
I just got a Ryzen 3600. What's the correct power plan to choose as of late 2019?


Long version:
Just from my observations on mine and a few friend's 3700x. Ryzen power plan seems to aggressively ramp up cpu frequency to 4.1ghz when sitting idle. Voltages are shown as 1.45v to 1.5v. VSoc is a whopping 1.4v??? Load vDroops vCoreto a safe level at 1.35V. But not liking 24/7 1.4v, I selected high performance power plan instead, and set min processor state to 85%. Now I get 1.0vCore during idle and Load performance remains the same at 1.35volts.

Further, selection window's balanced plan with min processor state 5% drops vcore down to 0.4v at idle, and load performance is the same firestrike performance seems within margin of error.

So what is the "right" power plan to choose now as of August 2019??

Test each plan using CPUZ bench. It's quick.

Leave Windows Power Settings to Balanced.
Unsure on AMD Power stepping CPU wise but leave enabled.
You do not want the CPU using a overclocked frequency all day and night with voltage, it's a waste if it's not doing anything.

Leave everything else at Auto except DRAM Voltage which you can set using Ryzen DRAM Calculator by exporting your RAM timings summary in nanoseconds from Thaiphoon Burner into Ryzen DRAM Calculator.

Also check your voltage using just CPU-Z, only that one shows the correct values.
Ryzen Master is the only one that shows correct sleep states for cores. Most cores if not all should be asleep when system's idle.

HWiNFO64 voltage is correct for me.

Thank you, I've done tests with a multimeter back when I used a c7h mobo and the vcore stated by cpuz is correct, the hwinfo64 one not so, usually lower than actual.

Didn't really look at HWinfo64's latest beta, they might've fixed that, it gets updated pretty regularly.

AMD stated themselves that CPU-Z shows the correct voltage while Ryzen Master does not

In any case, CPU-Z and HWinfo64 have the smallest observer effects when looking at power consumption from the plug but they still do increase the power usage.

VSOC and VDDG are stock values per The Stilt.
