High Ryzen 5 3600 Idle Package Power Consumption

[AsianLord]

My Ryzen 5 3600 at idle always sucks down at least 30-40W. Is this normal? I'm on the Ryzen Balanced Power plan. I've just switched over from my 2600 where it idled 15-20W. Also I've noticed that the CPU core power and Soc Power don't at all add up to the CPU package power. Where does the other power come from?

The Soc power is the VDDCR_SOC rail.

VDDCR_CPU (Core) and VDDCR_SOC and the rest-of-chip power that isn't probed.

Do you know how I can reduce the idle power consumption as I've seen others that have got their 3600 idling at 20W?

You can use "power savings mode" and that should reduce idle power consumption. 

 

There's also a third party program called QuickCpu that will allow you to fine tune frequency and boost scaling as well as core parking index on the fly. This may be of some benefit as well.

TL;DR ~15w idle 3600 (according to HWInfo).

 

Mobo:

ASRock Phantom Gaming 4.

2x sticks of 3600, cl16 memory where I immediately turned off the RGB.

 

Before you bring out torches and pitchforks yelling at me for having unreasonable numbers, I won the silicon lottery big and my 3600 is a beast.

 

I'm running a static, all core overclock. 4.3 ghz @ 1.2v. (4.275 is p95 small stable, but I never run p95 anyway so 4.3 it is).

4.2ghz runs p95 stable @ 1.1625v which was my setting for the past 6 months.

 

Infinity fabric locked to 1800, to match 3600 cl16 ram kit.

 

The 'real' secret sauce to lower power consumption appears to be setting 'low numbers' into bios, that aren't low enough that it crashes or fails to boot. Specifically anything voltage related. Make sure you know how to clear cmos before embarking on this adventure.

 

While I don't mind sharing exact settings I don't think they'll help unless you run the same motherboard.

 

Can get much lower idle consumption but don't really need to at this point.

*Also, scrub your pc clean of anything it doesn't need to run at startup.
