I overclocked my FX-4100 on asus m5a78l-m lx v2 mobo to 4.1Ghz so the temp was hitting 82 Celsius. So I undervolted the cpu which was hitting around 1.4-1.5 volts to 1.38v. The temp came down to 60 Celsius which is pretty good and the cpu is super stable, no BSOD after 40 hours of gaming. But when I lowered the voltage to 1.36v it still was hitting 1.388v. No matter what lower value than that I set it won't go under it. I am just curious to know if it's a safety feature and is it normal. I don't need to go lower than 1.388v but I just want to know if everything is normal.
