I've had a few RAM sticks fail, but the ECC usually caught it first. Also had one case that somehow the stick slightly unseated itself; dunno how but it was out of service for months until someone opened it up and reseated the stick.
...granted though I've also seen a backpane on a server fail. I didn't think that was even possible until that point.
