AMD 6300 Overclocking, Voltage and Temp

[swonkeydonkey]

Right now I'm attempting to Overclock my AMD FX 6300 through AMD Overdrive Auto Clock but every time it goes above 4.2 Ghz my Pc crashes when I looked it up there was a forum on here saying That upping the voltage will help but I would like to know is the Voltage Boost setting on Auto Clock safe? Adding to this I would also like to know what the maximum safe temperature is for the AMD FX 6300 as right now in auto clock it's at 19 x multiplier and is at an almost constant 65 C and climbing while all my other components are at 36 C lastly is the auto clicker also stress testing the pc because I'm worried if I over lock it that'll be the base idling temp

Doing it by software rarely produces good OC, best to do it thru BIOS. AMD recommends max 1.5v and 62c core temperature.
