two core voltages?

[toph99]

i was setting up motherboard moniter a while ago, and it asked me for core 1 voltage and core 0 (i think it was those two, it was a long time ago) and i was wondering what is the difference between the two?

Just a guess but i think it was looking at the Vcore and Vio.

Some people run dual cpu that's why, the one you want is the one that shows a voltage, the other one will show zero volatage, simple.
