Undervolting

Open Shuzhengz opened this issue 3 years ago • 14 comments

Maybe we can add undervolting feature? (it saves a lot of battery and reduces heat, but the user has to tune it themselves because it affects stability)

Oh, yess!

Undervolting is very dangerous and can permanently affect a computer.

actually nope, undervolting is decreasing the voltage of a CPU to decrease the TDP, so it's the opposite of overclocking and doesn't damage the CPU. The only negative effect is bad stability, but that can only happen if you undervolt the CPU too much

What about if you undervolt to a point that your cpu cannot function anymore and your pc won't boot.?

That would be bad, let's never change the voltage, wait, but maybe acs would be a cool Linux overclocking util

Do any other overclocking programs that exist?

JakeRoggenbuck avatar Feb 03 '22 22:02 JakeRoggenbuck

For Linux specially?

The BIOS resets the voltage every time it encounters instability, so that wouldn't happeb

Yea but Intel processors cannot be overclocked, unless its an i9, X series, or K series AMD Desktop processors can be overclocked, but not mobile

Shuzhengz avatar Feb 04 '22 00:02 Shuzhengz

Oh, so very few, and especially not mobile as in laptop?

JakeRoggenbuck avatar Feb 04 '22 00:02 JakeRoggenbuck

yee although some laptops use desktop processors (old thinkpads, alienware, some other gaming laptops)

Shuzhengz avatar Feb 04 '22 04:02 Shuzhengz

also most overclocking are done through the BIOS so yee

Shuzhengz avatar Feb 04 '22 04:02 Shuzhengz

ah, yea
