 None of the AMD K5 CPUs I own have a "PR rating" on them.
 I've only ever seen such ratings on Cyrix/IBM 6x86 series CPUs.

 I have no clue what sort of K5's YOU use, but *ALL* of the K5's I have
ever seen or worked with run with CPU clock speed set to the speed equal
to the name of the chip - K5-75 at 50x1.5, K5-90 at 60x1.5, K5-133 at
66x2, K5-150 officially at 60x2.5 (see below), K5-166 at 66x2.5.

 Never seen one of those.

> BTW, AMD claims that they never made a K5-PR150

 I have an AMD K5-150 in one of my machines - overclocked to 166. I had
to slow the memory timings down a HAIR to do the overclock reliably -
but it is now my FASTEST RC5 key cracker, by a hair over any of my
 Go figure!
