Ryzen 5600X voltage fluctuates between 0.9v and 1.4v when idling

Hi!

 

I recently upgraded to a Ryzen 5600X CPU, and it's all fine, but I'm experiencing something a bit concerning: when idling, even without background programs running, the CPU keeps jumping between 0.9 and 1.4v, but mostly hovers around 1.4v when idling, which feels a bit too high. It also usually chills between 50-55 degrees at idle, despite being cooled by a big BQ! Dark Rock 4 cooler(it's well seated, well spread paste too).

 

Is this normal? Or should I maybe change some settings in the BIOS?

High(er) idle voltages for Ryzen have been there for a few generations now. It's expected behavior.

It is normal. When the CPU is under load Vdroop will occur and drop your voltage as needed to reduce temp. When people overclock they push their frequency so high they need higher than stock voltage and also have to combat Vdroop with LLC so it wont drop to unstable levels. If you're running stock you don't have to worry about this.

 

Your temp is also perfectly adequate. You maximum operating temperature (TJ Max) is at 95°C so 55°C is obviously nothing to worry about.

 

EDIT: For best performance and temperature it is recommended to install chipset drivers from your motherboard vendors website and use Ryzen balanced power plan in Windows.

1.4v is fairly normal for a short burst of CPU usage. Even though you have no background tasks, Windows will be constantly performing small tasks here and there. You're most likely just seeing a maintenance task hit a core for a brief moment before ramping back down.

That's totally normal behavior for Ryzen. Since you have a 5000 series chip, if you want to reduce idle temps a bit, you can look into doing a Curve Optimizer undervolt to reduce voltages. With 6 cores it wouldn't take long to even do a Per Core offset.
