1800X High Idle Voltage

[acperience7]

I have an 1800X on a Gigabyte AX370 Gaming 5. I haven't done any overclocking with it, as I just have an old 9900NT cooling it right now (waiting on a bracket from Cryorig so I can put my H5 on it). I don't really stress the system much apart from gaming. I noticed a few weeks ago in Ryzen Master that my idle voltage was high. Even after big bios release on the 11th though, and the 1.0.1 Ryzen Master update I would see my idle voltages hover between 1.43 and 1.51. The temps stay low (usually 36-47c depending on the ambient temperature). I decided to take my first steps into voltage manipulation because of this. I have been playing around in the bios for the last few days and I just can't seem to get idle voltage where I want it. I was able to make it a better, and now I'm seeing 1.45 idle. Under load (been using wPrime, Overwatch, 3dmark/Time Spy) It's pretty rock steady at 1.28v. It seems like my adjustments are working for load scenarios, but I can't figure out why I can't get the idle voltages down. Now I'm wondering if the idle voltages really even matter, or if I can even manipulate them. They don't seem to be hurting my temps. I've only had stability issues when I dropped the voltage too much on 2 occasions (wouldn't post once, and BSOD 2nd time). I plan on doing real stress testing when I can put my H5 on.

I'm a complete noob at this. I've had a Phenom 965, an I5 4670K, and now this 1800x. I never touched voltage settings before though, just did what I could on stock voltage.

Is your windows power plan set to high performance? It might be stopping your system from going into low power mode.

Wow, yeah that's what it was... I knew it had to be something simple I was overlooking. I downloaded that new "Ryzen" profile they released. Both that and the High Performance setting are causing the high voltage at idle. I guess it's normal then, as far as idle is concerned. Thanks for the help.

Sometimes those readings are "outdated" because the CPU put the cores to sleep and the voltage observation froze at that point being at high voltage. Another thing to keep in mind is that you should watch actual power consumption, the readings could simply be wrong. That said, usually Ryzen 7 1800X @ stock only does such high voltages when using XFR for highest clocks. There could be a app running which stresses the CPU so that it's using XFR for max performance.
