The clock frequencies are not "out of spec" -- the manufacturing tolerance is 32,000 +/- 0.5%, and virtually all the measured consoles are well within that range. The manufacturer additionally specifies a maximum of 0.3% variation due to temperature and 0.2% due to aging. There's also no evidence that the clocks are drifting further due to age. We don't have data for what APU frequencies used to be; we have a single measurement from over 20 years ago suggesting that one particular console had a DSP sample rate of 32,040 Hz, which is slightly lower than the current measured average of 32,075 but still well within the range of consoles we've looked at today.
