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 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 https://i.imgur.com/xsG0jSE.jpeg
- xyst 3y agoIntel chips in particular vuln to issue when under volted (mentioned in post) https://archive.is/4Mtnq https://archive.is/4Mtnq The wired article also mentions it is patched though. So maybe it has to do with avoiding a “non advertised throttle” lawsuit.
- hu3 3y agoThank 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.
