Undervolt? Yes or no?

[Tommynew]

There will be any side effect?
My cpu has 1.27x stock vcore, and when i run stress test it goes really hot so im thinking on undervolt it but i dont know if there is any risk.
Thank you.

What is your CPU?
At what frequency do you run?
What is the motherboard?
What is cooling?

Please follow the usual guidelines so we can help you.

i7 4790k.
"Stock" frequency, i mean, it runs at 4,4 with turbo but no "custom" overclock.
gigabyte ud3h.
cryorig h7.

It can handle 4,4 wit less vcore than 1.27 stock, but i dont know if there is any risk.

Thank you and sorry for the lack of information.

The biggest downside of under-volting is that it can cause system instability.

My 2700K is running at 4.2 Ghz at 1.21 vCore - which is considered an under-volt compared to the 1.25 vCore which is the stock option. I was running 4.0 GHz at 1.1 for about an year and for the past 2 or more I am running at 4.2 at 1.21. Technically - my CPU has being living under-volted all its life.

Should i go for it then?
Mainly for temp reason, i dont feel comfortable with such high temps.

The higher your CPU voltage, the more heat it produces. The relationship is voltage squared, so doubling the voltage would quadruple the heat!!!
More voltage allows you to run faster, but you need more and more voltage to get less and less performance increase.

In order to overclock my computer using only the stock cooler, I had to keep the voltage down to 1.15V

To summarise, lower Vcore volts is not a problem as long as your PC is stable.
If you drop the volts, you may also need to reduce speed a little.

Yeah, give it a try.

If it crashes, either turn the voltage up again, or drop the turbo speed to 43 and try again

I was running it at 1.18-1.20 stable last days with no problems, but i was wondering if it could cause any damage to the cpu.
I guess ill keep the undervolt.
Thank you.
