AMD 80386DX processor and coprocessor, clock crystal


Jul 8, 2004
I'm perhaps interested in doing some legacy overclocking. I got a very nice 386 motherboard with an AMD 33MHz processor in it right now as well as 20MB of RAM (4 sticks of 4MB and 4 sticks of 1MB). My goal would be to get the AMD 40MHz processor and matching coprocessor and overclock the system to 50MHz using a 100MHz clock crystal, but I would be willing to settle for any of the following combinations of parts needed:

  • AMD 80387DX-33 coprocessor
  • 80MHz clock crystal
  • AMD 80386DX-40 prcoessor
  • AMD 80387DX-40 corprocessor
  • 100MHz clock crystal
