[Cialug] AMD Athlon XP supplies may be drying up

[Aaron Thompson]

I believe that both socket 754 and 939 allow for both 32 and 64 bit
computing. The Athlon 64 supports both modes. Off hand I'm not sure if
the 32/64 change is performed  vi the mobo or an auto-magic thing. The
nice thing about the AMD64  processors is their FSB using the HTT looks
nice.
