Question No option to set NB Voltage over 1.4

What makes you think you need 1.5? What settings do you have? What are you trying to reach?

I know you don't want hear this, but i suggest ditching the system. S775 had its day. You are talking about a system from a decade ago. A stock i3 or ryzen 3 is faster than whatever you have, even if it's OC'd. It's time for a new system.
