alt Hacker NewsUndervolting would definitely help, and is the actual fix. The current Intel fixes were mostly just for the symptoms, as the main issue is high voltage+power when pushing high clocks, but they can't actually fix that as it'd downgrade the advertised clocks the cpus were sold with
Sorry, but that understanding is dangerously incomplete. You're describing the first set of issues they uncovered, but there's also:
"Microcode and BIOS code requesting elevated core voltages which can cause Vmin shift especially during periods of idle and/or light activity" (emphasis mine)

Recall also that "Vmin shift" means "the minimum voltage the processor needs to run correctly goes up" so if the issue isn't addressed, that level of undervolt may stop working
