I agree, but see below...

Often the 533MHz 21164 processors were exactly the same as the 600MHz
varitiy. The same _sometimes_ goes for the 500MHz processors, but not
always. From what I remember (which could be fuzzy or plain wrong) is
that the ones clocked at 500MHz were processors that failed to operate
under certain conditions at 533MHz. I personally have overclocked a
21064 from 166MHz to 200Mhz for about a year and breifly tried it at
233MHz (day or so) but was afraid it would end up as a puddel in the
bottom of the case... I currently have my 533MHz 21164 overclocked to
600MHz for more then a year and it's fine. I can wrap my fingers
around the heatsink and it is cool to the touch (not hot, not
even warm, but cool). So I believe it to be ok overclocked. I've built
dozens of kernels for it and countless packages for Debian without
finding a single error.
JMO && YMMV
