I personally wouldn’t risk running a 624MHz device at 728MHz. The 663MHz is in my opinion the highest safe speed for your processor.

I also have a Mitac Mio A701 and I can get it to run at 624/208/104/104 just fine, but when I jump up to 663 it runs fine but my lcd flickers and the sound is scratchy.

Is there a way I can adjust the LCD to 104 instead of the 55 it runs at when I try to test 663?
