those can but 10nm CPUs after Plundervolt can't undervolt , it's disabled from UEFI and not only there's no option to reenable it in the UI, the very EFI variable itself is write locked. I have an X1 Gen 4 (Intel 11th gen) and you just can't do it.

Damn, you mean we can't just swap resistors to under/over volt anymore?

I am getting old.

(tongue in cheek, and yes, I am getting old)

Shit, I remember just using a pencil to lower resistance values.

I remember some boards, you would have to paint a cpu pin with nail polish to stop it from conducting, or carefully jump one of the several hundred pins on the socket…
