Yeah. They can’t replace it with their upcoming 15th gen, because that uses a new, incompatible socket. They’d apparently been handing replacement CPUs out to large customers to replace failed processors, according to one of Steve Burke’s past videos on the subject.
On a motherboard that has the microcode update which they’re theoretically supposed to get out in a month or so, the processors should at least refrain from destroying themselves, though I expect that they’ll probably run with some degree of degraded performance from the update.
Just guessing, not anything Burke said, but if there’s enough demand for replacement CPUs, might also be possible that they’ll do another 14th gen production run, maybe fixing the oxidation issue this time, so that the processors could work as intended.
