The biggest problem from the AMD debacle is going to be for those who bought Zen 4 prior to the new BIOS updates. Especially those of who bought them at launch or even 3 months ago. According to Steve, the failure analysis lab is telling him that those who have been using Zen 4 CPUs all these months with higher voltages could be facing an unknown amount of damage and degradation already. So a higher quality chip could turn into a lower quality chip. Remember that higher quality voltages would happen just by turning on Expo. I'd avoid used Zen 4 chips like the plague.
