On: How to reenable undervolting in 2020 Dell Laptops ...

[hu3]

I followed a similar technique to undervolt an Acer Predator with an i7 11800H processor by -100.06 mV.

And the result was a 15 celsius reduction in average CPU temperature and improved performance, incredible. I can rarely hear fans now.

I wonder why isn't this the norm. Perhaps some chips become unstable?

This is the guide I followed on Youtube: https://www.youtube.com/watch?v=X_OFOmfjs6k

And here is a relevant screenshot of the bit to be flipped in the video: https://i.imgur.com/xsG0jSE.jpeg

Intel chips in particular vuln to issue when under volted (mentioned in post)

The wired article also mentions it is patched though. So maybe it has to do with avoiding a “non advertised throttle” lawsuit.

Thank you! This is why we can't have nice things.

Many intel laptops could be improved significantly. But because a few could exploit that, many have to pay the price of hotter, noisier, less powerful and less energy efficient laptops.

I guess I'm not interesting enough for hackers to mess with processor voltage so I'll keep it quieter. Or perhaps it was indeed patched.
