My AMD DX2/80 works fine. However, it required some changes to the
jumpers on the mainboard: these were in addition to changing the clock
speed. Assuming your mainboard supports the AMD chip, you should be
able to contact the vendor to find out the correct settings.
My mainboard arrived with incorrect settings, and it did have some strange
problems (failing to start on the initial power up, failing to reset,
etc.) I would suspect your mainboard, not the CPU.
