FSMC clock signal at higher frequencys

Hi,

I am trying to control a TFT over LVDS with an STM32F429. At around 30 MHz the Signal seems to be ok, but the Display wants at least 40MHz. Turning up the Speed above ~33Mhz is messing up the clock signal and visible errors occur. The datasheet says it should work with up to 42MHz. Is there a chance to get a clean 42Mhz signal by following some Layout rules or adding some components (until now i added a resistor and a capacitor, that got me up to 33Mhz) or should i switch to another controller?
