    safe voltage for 2500K

    tomr

      Hello mates, I talked about this matter with parsec, but we wasn´t able to find out any clear answer. So I hope somebody real experienced may be found here, who would brind a light into this dark alley :-)

       

      My situation:

      I have 2500K overclocked to 4.5 GHz on 1.345 V set in BIOS. As You can see, Intel power management automatically drop CPU frequency to 1.6 GHz (95% of time, because PC is not stressed by any demanding applications). BUT! Since I set voltage to 1.345 V in BIOS, it won´t drop too, but it sustain on 1.345 ALL THE TIME (= CPU frequency is 1.6 GHz X voltage is 1.345 V !). People insured me, that such voltage isn´t problem (= doesn´t harm or reduce CPU lifetime dramatically), since temperature is low (= under 60°C, which my Noctua NH-D14 manage easily :-) By the truth, temperature is no problem at all, since it sticks below 30°C as long, as CPU is not stressed, high voltage or not...

      Still I think this is not absolute answer (because if temperature would be the only problem, I could set 1.5 V and nothing bad would happen, because if I won´t stress CPU, temp. will stay below 30°C all the time). But OK, I believe them. However...

       

      My "simple" question:

      How does voltage itself influence 2500K ??? Respectively, what bad high voltage does to this CPU, if it won´t burn it???

      + bonus question (if you would know :-) -   what range of voltage is "ideal" - "acceptable" - "not recommended" - "dangerous" for 2500K if we consider automatically dropping to 1.6 GHz most of time, but sustaining voltage on the same level?

       

      PS: well, this question I consider to be a nut, because event Intel support wasn´t able to provide me any qualified answer! So, who of you dare, mates... ? :-)

       

      Thank you for your very welcomed replies!!!
