What is the difference between offset voltage and manual voltage?

What is the difference between offset voltage and manual voltage?

Offset voltage changes the voltage in increments, e.g: .025. Where as manual voltage is set by the user and doesn't have restrictions (some boards only let you change in increments of 5) but basically as manual as it gets.

[Konrath]

Offset voltage will allow your motherboard to push less volts to the CPU when it is not being used as much whereas a Manual voltage will always yield that set voltage level.

 

For example if you use Offset, it could look something like this:

Idle: CPU Volt: 1.05v

Load: CPU Volt: 1.25v

 

If you use Manual:

Idle: CPU Volt: 1.25v

Load: CPU Volt: 1.25v

 

Basically Offset voltage is a way that you can overclock your CPU to get more performance out of your CPU only when needed.  This can potentially expand the life of your CPU over a manual clock because you are not constantly pushing unneeded volts.  As to how much degrading (if any) I could not answer that question.

The affect is usually negligible, it raise temps though and that does shorten chip life.

Most of the time a system is idling but if you don't use speedstep or the balanced power plan then it won't undervolt so it won't make a difference to lifespan. Manual voltage just sets the voltage to a fixed voltage that's static 24/7. Offset voltage works complety different; when the CPU needs to raise the clock speed the voltage will just increase dynamically with the clock. Eg 1200MHz 0.7V - 2000MHz 0.9V - 2500MHz 1.0V - 3200 MHz 1.15V - [here your max OC] @ vcore under prime95

Lifespan is just irrelevant, you're just coming with prediction stories so it's pointless to argue about it. Probably the most obvious things you'll encounter are degradations -> CPU starts to ask more Vcore to be stable over time. Few factors that cause this: usage/clocks/volts & temps so you just either speed up the process or you just try to keep the degradation process (which will be always there) minimal like use speedstep/offset if your system idles most of the time. 

If you never idle and lets say you mine 24/7 with your cpu well then it's not going to make any difference.

So basically offset voltage helps you save power and lowers temps if your idle.

Good!

[Nexo]

Alright Offset to save power!!!!!!!!!!!!!

[Nexo]

How do I find the offset voltage though? 

[DSD27]

If you have asus board, just use manual voltage, and whenever you want to save power, select a EPU profile on AI suite, its easier and you save much more power

[Nexo]

I don't have a ASUS board.
