CPU voltage

What is the difference between Vcore and CPU core voltage? 

[pstarlord]

Vcore Voltage is the voltage supplied by the VRM to your CPU

CPU Core Voltage supplied from the CPU for its internal use.

 

If i'm wrong, someone please correct me, but this is how I've been understanding it. 

 

The PSU sends the power to the VRMs, the VRMs distribute the power to the CPU as needed, and the CPU then distributes within itself to run its internal functions.   

 

The values we see on hardware monitoring programs are based off of sensors placed at certain points within that chain.

So should I bring down the Vcore voltage if it is much higher than the CPU core voltage?

What motherboard is this?
Usually they are the exact same thing.

But depending on motherboard, this could be socket sense, die sense, or VID.  They are all different.

Oh ok I can't help with AMD hardware, sorry

For undervolting?  Just use "Voltage Control" setting on Ryzen Master.  

 

If you're doing it in your BIOS, adjust one and leave the other on "Auto" and I believe it should adjust itself.  They should be the same in theory because the CPU voltage pulls from the Vcore Voltage.  I think I usually adjust VCore, for what it's worth.
