I'm pretty convinced they ship "underclocked" chips now and then.
If you remember the thunderbird AXIA, it came as 1000 MHz chip, but most of
those babies would run at 1300, some even managed +1400 MHz.
That is pretty good for a 1000 MHz chip, a little too good.

of course later even better steppings came out, and it was clear (at least to
me) that those were not genuine 1 GHz chips.
