The AMD 5x86-133 is designed for 4*33Mhz, but was successfully
used with 3*40MHz in many systems (and slighlty faster that way).

On the other hand, it can safely be over-clocked to 4*40MHz, 
and I'm quite sure it wouldn't mind being run at 3*50MHz :)

So, if you want to give it a try ...
At 3*50 it should be about as fast as a P-100 (under FreeBSD, 
with non-Pentium optimized binaries as created by the stock gcc).

PS: If you really want to overclock an AMD 5x86, try to get the
    ADZ version, which can be used with no heat sind or fan at
    133MHz ...
