Overclocked ryzen and power consumption

[hsp70]

I know that normal overclocking of ryzen disables the power saving features and the CPU will always be running at the overclocked speed but is there a significant excessive usage of power when the cpu is overclocked but isn't running any intensive programmes?

There is something called pstate overclocking that I can try so I am not wasting energy? I think the board I bought, a taichi supports this.

You can overclock and lower voltage using the power states from what I've seen. I'm not sure what effect this has on actual power draw though. You'd have to get a meter and see.

The is not an increase in idle power consumption even with pstates disabled. The Ryzen chip still manages to significantly reduce power consumption to below 0.1w per core.

You can view this behaviour using software like hwinfo. I do not get lower idle power consumption at stock with pstates enabled. I have also measured at the wall.

Thank you that's what I wanted to know

So is that with neither voltage nor clocks dropping that you noticed essentially no difference at idle in power consumption?

How much stuff do you have running as standard?

For me, mine is usually sitting under 10% usage but over 2%, as I have a lot of processes running. So hardly ever doing nothing.

If I have vm running that increases that min a bit.

But then, I have noticed that when using pstates to Oc, it hardly ever drops voltage, even if it's dropping clocks fairly often.

Correct.

As for background processes, I have next to none running that use processing power when idle. The screenshot above is an accurate reflection of idle for me. The maximums you see are with a heavily multithreaded application (distributed computing).

The biggest impact you can make to idle power consumption is getting the SoC voltage down as low as possible.

Cool.

And if you have compared hwinfo info to socket reading and found them to be similar then perhaps I will rely on that as a gauge.

Given how little the voltage drops on mine using pstates, I don't think it's worth me bothering.

I did want to get it as low as possible with oc due to this running 24/7, but may just give up on that idea.
