Overclocking processor 4790k
Overclocking processor 4790k
Running at 4.7ghz, 1.3v atm, 69C seems safe to increase to 4.8ghz and 1.356v. At this voltage I experience 75c. Done with small ffts v26.6 prime95. CPU is delidded.

75c is pushing the temperature, but it's safe. That's a great overclock at that voltage—just a bit of luck on your side 😛.
You should aim to keep temperatures below 80°C at most. Most people target around 70°C max. Going above 80 for extended periods might harm your CPU, though not always true. 90°C+ is likely to cause damage, but it's probably out of your reach.
About the voltage: won't 1.356V damage your chip?
No, it won't start damaging until you hit very high temps or go past about 1.45V.
1.4V is safe (roughly), but
REALLY starting to push it.
You have some data to back up what you're saying—seen a lot of people...
75c is handling the heat well, but it's a great overclock at that voltage—just a bit of luck on your part.
You should aim to keep temps below 80°C at the highest, most people target around 70°C. Going above 80 for extended periods might harm your CPU, though it's not always guaranteed. Temperatures over 90°C are likely to cause damage, but you probably won't hit that level.

Regarding voltage, will 1.356V harm your chip?

For safety, try to keep temps below 80°C at the highest; most people aim for around 70°C. Going past 80°C for extended periods could harm your CPU, though it's not an absolute rule. 90°C+ is likely to cause damage, but you probably won't hit that.
Regarding voltage, will 1.356V harm the chip?
No, it won’t start damaging until temperatures get too high or voltage exceeds about 1.45V. 1.4V is safe (roughly).
REALLY, pushing it this hard is risky.

REALLY starting to push it is pushing things too far.
Do you have any evidence to back what you're saying? I've seen many people mention above 1.3V shortening the lifespan and other issues :S
Another issue here is not muck gain with an extra mhz. Maybe it's about bragging rights. I checked with my 4790k and found 4.7 is the sweet spot. I require 1.4v for 4.8. It doesn't seem necessary for me... What voltage did you need for 4.7?

75c is increasing the temperature a bit, but it's still safe. That voltage is a great overclock, just be lucky. 😛
You should aim to keep temps below 80°C at most, most people target around 70°C. Going above 80 for extended periods might harm your CPU—though not always true, 90°C+ could cause damage eventually.
Regarding the voltage, will 1.356v harm the chip?
No, it won’t start damaging unless you hit very high temps or go past about 1.45V.
1.4V is acceptable, but pushing it further is risky.
Any evidence you have supports your point? Many users mention that above 1.3V the lifespan drops significantly.
It will gradually drop around 1.4V, but it’s not a big deal—it won’t fail immediately. If you’re unsure, it’s better to avoid it.
There are plenty of discussions online; just search for max temps under 1.4V. Intel suggests up to 1.55V, so 1.356 is perfectly fine.
