How to Undervolt 1055T?

[LatetotheGame]

Hi, I have asked an year ago how to overclock my CPU and after your good Recommendations I would like to ask for the reverse.

I have:
1055T
Asus M4a89gtd Pro

I need a NAS and due to too high Hardware prices I am currently not willing to get a new one. So, I want to try this one and hopefully save some Energy with Underclocking.
Hope you can help me with that.

I have read that some people were able to get it down to ~1V, but due to my Board I can´t even get close.
I would like to know if I overlooked something.


I have there a "CPU Offset Voltage", it can be increased by like 0,7V, but only reduced by 0,06V, which gets me down to ~1,28V. A far cry from 1V. However, it says that the Minimum for this Field is 0,035V.
Did I overlook something or is there really no other way to reduce my CPU Voltage with this Board?

There is also NB Offset and VDDA Voltage, can I do something with that? Is there any use in undervolting the other Fields?
How about deactivating Cores?

Do you have a manual CPU core voltage setting you can use instead of offset?

From the manual...

There we go, so set the CPU NB Voltage to manual and you'll get a setting to directly control the CPU Voltage instead of having to use an offset.
