I was having this issue of not being able to get idles below 1.4xV. I believe I have fixed it in my case. What I did was:
- Update to Latest bios and chipset driver
- Set VCore to "Normal" instead of "Auto" within the bios.
- Set Windows Balanced Plan (This does not work with Ryzen Balanced Plan)
- Set Minimum Frequency to 0% in Windows Balanced Power Plan (it was at 5% by default)
- PBO is "enabled" via bios
- XFR is set to Profile 1 (3200 c14)
- DRAM Voltage is set to 1.35v
Now, using CPU-Z OR Ryzen Master, I am showing voltages at 1v or below at idle, but boosting to 1.3x and 1.4x sometimes. Before I made these changes, CPU-Z and Ryzen Master showed locked high 1.4x volts. IF I
switch back to Ryzen Balanced Power Plan, it will stay at 1.4x idle in both CPU-Z and Ryzen Master (not viewing them at the same time). I also tried editing Ryzen Balanced Power Plan to 0%, 5% and 1% minimum frequencies, but none of them seem to work in terms of fixing idle volts. If I change Windows Balanced Power Plan min frequency back to 5% or anything like that, volts go back to 1.4x at idle. BTW, my idle volts now are running EVERYTHING in the background, meaning Steam, Origin, Uplay, Epic Game Store, Discord, Antivirus, Corsair Link, etc. I really believe this is either a bios issue, but more than likely its a Chipset/Ryzen Power Plan issue.
