-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Since you've mentioned the remaining lands are also misaligned, I'd throw that CPU away. You currently risk burning out the multiphase regulator and/or attached peripherals (RAM, PCIe), depending on if the lands are now misaligned enough to put voltages where they don't belong.
Those lands are very robust; the only way I can think of to chip off one or two would be putting the CPU land-side up and dropping something on it. For more extensive damage, it's possible the CPU was repeatedly overheated at some point in the past as well.
