All I did was follow the screen shots in the link.
I am not savvy enough to know how it raised the voltage, but I believe that it may have adjusted it automatically. Hence my asking for someone's quality advice on how to adjust it. Whether there is an auto setting to change or manual setting.

My question is: how can I lower the voltage? I don't know if I want to run over 1.4 V 24/7.
Are you planning on running your system maxed out 24/7? If not, then setting Vcore a little bit over 1.4 won't hurt. 90% of the time Vcore will be much lower than that as long as you have the turbo function enabled.
The other way to lower Vcore and have a stable system is to lower the multiplier on the CPU so that less voltage is required.
