When buying used Epycs you have to contend with them possibly being vendor-locked to a specific brand of motherboard as well. https://www.servethehome.com/amd-

  They sell this vendor lock-in "feature" as enhanced security?
  • Uvix 2y ago
    Yes. It keeps the board from booting if the firmware is replaced with a version not signed by the board manufacturer (i.e. so an attacker can’t replace it with a version that does nefarious things). Preventing CPU reuse in other boards is just an (unintentional?) side effect.

      The cynic would say the security implications are the side effect, since selling more, new chips is the goal.

        If that was the goal then the CPU would fuse on first boot for any manufacturer’s board, rather than being fused only by Dell boards.
