Your statement is hard to parse - to figure out what you're really
saying.  VMware 5.5 runs fine on AMD Athlon64 3700 (754-pin) systems if
you are running a 32-bit host and want to run 64-bit guests.  If you want
to run a 64-bit guest you need a revision D or later Athlon64.  64-bit
754-pin Semprons qualify.  It isn't an issue of the number of pins the
CPU has.  You cannot run a 64-bit guest on a 939-pin rev.CG Athlon64.
