Ok. One more thing... Do you know what a safe voltage would be if I'm running at 4.5ghz? I don't want to fry my chip but I want it to be stable. What's the equation to figure the voltage out too?
There isn't an equation unfortunately, all chips have different overclocking ability, so some chips may require more voltage than others, or perhaps less...
I would try 1.3V to start with, do alittle bit of stress testing and if it's ok then lower the voltage slightly (something like 1.290V) and test again, repeat this process until it's unstable and then increase the voltage slightly and test for 8+ hours.
If it's not stable with 1.3V then try slightly higher, but remember to keep an eye on those temps.
I wouldn't recommend using over 1.4V for 24/7 use.
