It should be stable if it's synchronised with the motherboard, the main problems are:

- the peripheral clock will also be double speed, messing up things like CIA timing that can affect some games (fixed using a toggle flip-flop to halve its frequency)

- it's mostly pointless because the CPU has to wait for the motherboard RAM to do anything anyway. The 68000 has no cache to use, and the 68010 cache is so small that only very specific code can take advantage of the speed. So your 68000 could be 1GHz, but it still has to access the chip RAM at 7MHz to load an instruction or data and store a result.
