I have a MSI z97 PC Mate MB and changed the multiplier to 40 giving me 4.0Ghz. I didnt touch the voltage settings and when I check cpuz, i see that the voltage is 1.29. Temperature hovers between 65-70C with Prime95 running. Am i doing something wrong? I've read lots of threads where people are getting 4.3 at 1.15 volts. Do i need to manually lower the voltage setting? Thanks!
