CPU Voltage Fluctuations

I've set my vcore to 1.2V in the BIOS but at idle it will flick between 1.2 and 1.208, under load it increases to 1.224V.

 

How to I keep the voltage constant?  Also, is it best to keep a constant voltage and overclock or have the clock speed and voltage drop when at idle?

its best to have the voltage drop when not under load and those fluctuations are not really something i would worry about

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

Sounds like you have LLC enabled. Lower the LLC and it won't go as high as 1.224V. Have it too low though and you'll drop below 1.2V under heavy load.

I personally have never had any ill effects from using off-set voltages. It takes longer to set up and can some times be a headache at the beginning to get it correct but works well after.

It's not a race to the bottom.

Great, thank you, I'll keep it as-is for now then.

Good to know, I might mess with settings down the line if I need to.
