hi guys so i recently purchased an i9 9900k with a msi z390-a pro during load i noticed the vcore running at 1.42v so i decided to download xtu and use an offset of -0.9v however since my voltage in bios is set to auto vcore consistently changes and at idle runs at around 0.75v . so is this fine can i decrease the offset more and what is the minimum vcore for an i9 9900k for example if it drops to 0.6 at idle would that still be fine
 
Solution
Any particular reason you wouldn't manually set your voltages in the BIOS itself, opposed to leaving on Auto?

With an offset, at idle (800MHz), you should be fine at 0.6V.
