Hello everybody, may I ask you one "simple" question. I´ve asked it few times before, but I still didn´t get a clear answer :-( So I hope, that here I will get my answer since I believe, I am at the best place to ask :-)
I purchased SB 2500K, which is meant for overclocking and get these results:
Intel burn test was stable (20 runs) on 4.5 GHz ~ 1.305 V
However Prime95 crashed in few second. 4.5 GHz in Prime95 was stable (22h 30min of running) on 1.345 V (max temp. when testing was 56°C).
Some friends of mine told me, that "overpowering of CPU" may cause harm to it or even reduce its lifetime. On the other hand, some insured me, that I shouldn´t worry about it... However, I am new for overclocking and I would finally appreciate some experienced advice very much... :-(
Most of time (like 95%) my CPU frequency drop automatically to 1.6 GHz (because of ASUS motherboard power management), BUT voltage reamains on 1.345 ALL THE TIME!
So result is, that CPU temperature is below 30°C, but it is in 95% of time provided by far much more voltage, then it actually need.
So my question is really simple...
-> can high voltage itself harm or reduce lifetime of CPU (even if temperature sustain below 30°C permanently)??
You see, temperature is not problem at all, since CPU is not stressed (and even if it is, I can keep it under 56°C thanks to my cooling system).
PS: in the extreme way of thinking (only for my better understanding) - what if I would rise voltage of 2500K for example to 1.5 V on 4.5 GHz, but CPU would still stay below 30°C? Is voltage itself problem to solve or I shouldn´t worry about it?
(You see... there will be logically some unused voltage anyway most of time on each PC, since nobody stress CPU 24/7... )
I am sorry for maybe banal question, but as a new overclocker I don´t understand principles of CPU power management a lot yet. So I hope I get some lesson here :-) Thank you very much for possible explanation or this problematic and any experienced answer!!!
