The part replacement isn't being blocked? The OP's CM5 with replaced RAM is still a working CM5 according to him. And fully functional compared to before the replacement.
replyThe part can be replaced with the same part to repair the item. This is not locked.
replyPart locking against unoriginal parts is prohibited in the EU.
reply"Each chip is programmed with the timing settings and storage size settings of just the RAM we ship it with, and doesn't know how to boot with anything else." I don't know if you could call that "blocking." I mean you could call it that but I don't know if that's legally what it would be.
