The Canon 1DX is 12fps in high speed mode. The next speed down is sadly 3fps. At a low power, can the E640 recycle at this high speed via CC?

It should be able to. We have tested to 10fps, but as of yet, we are not able to reliably test 12fps. Even still, At worst, you would get 6fps with untriggered frames in between. It is strange your choices are 12 or 3.
