CPU model is Core i7 4790K with OC at 4.8
Multiplier stands at 48
Operating voltage is 1.355
Memory capacity is 16GB 1866 G.Skill
Power supply provides 750W
Motherboard brand is Gigabyte Z97-X Gaming 5%
Performance remains stable during IETU and Aida64 tests at peak temperatures of 78°
Current attempts to reach 4.9 GHz have failed consistently, requiring more than 1.4 volts core and resulting in crashes
Questions remain whether the CPU has reached its voltage limit or what maximum stable voltage is safe before damage occurs
The voltage is really very high, that's why you're ruining your CPU's lifespan. Probably it won't last more than ten years at best. But right now it's better to let it run at this level unless you can push it another 0.010 without trying it in any case. I just upgraded to this CPU a month ago, and it's only reaching about 78°C under stress. Maybe lowering the V Core a bit would help. I'm worried because you're saying I'm shortening its life, but why do others overclock this chip with higher voltages if you say 1.355 is so high? Don't worry about lifespan—it's not that important right now.
The voltage is really very high, aren't you? This could be shortening your CPU's life. Just don't jump to conclusions—maybe it'll last only about ten years at most. But right now, it's better to let it reach that level if possible. If you can't go further without adding another 0.010 of V, I won't attempt it in any situation.

That voltage is really too high, you're really hurting your CPU's lifespan... Probably it will only last about ten years at most. But right now it's better to let it run at this point. If you can't go further without adding another 0.010 of V, I won't try it in any situation.
I just upgraded to this CPU a month ago, but it's barely reaching 78° when under stress, and maybe lowering the V Core a bit would help. I'm worried about the lifespan, even though others seem to be overclocking it with higher voltages—why is 1.355 so high?
The voltage is really high, you're ruining your CPU's lifespan... Probably just a short 10 years at best. But right now it's better to let it run at this level if you can't push it further without adding another 0.010V. I've upgraded recently and it's only been a month, but it's already reaching 78°C under stress. Maybe lowering the V Core a bit would help. I'm worried about the lifespan, but others overclocked the same chip with higher voltages—why is 1.355 so high? Don't worry about life span, it's not noticeable. Upgrades will fix things before damage becomes obvious. Temperatures are fine, and some people really push the limits. That causes lasting harm after a while, usually around four years. Just let it run and don't go further.
