Amptron problem with 133 bus?

Amptron M756LMRE. Runs fine with Celly 1100. Tried my 866 in it and Windows won't load.

Tried different RAM sticks, restoring older registry, Scandisk, Scanreg, different CAS. No luck.

Popped the Celly back in, no problem. ???

This thing shows that it supports 133 FSB chips. It has a jumper that is for selecting slot 1/PPGA or FCPGA. The jumper was left on slot/PPGA setting and I changed it too, but no luck. But it ran the Celly with the slot/PPGA setting no problem.

CPU selection is through BIOS.

Any ideas?

You checked the PCChips forum yet?
Its basically the same board.

I saw posts in the claiming to run 1.1 P3's...
Might only be the 100FSB though.
