overclocking internal oscillator?

[Acetronics2]

I have a 16f688 outputting music using the FREQOUT command. When I define the internal oscillator at 8 MHz the audio is slightly warbled and plays faster than I would like, but when I define the internal oscillator at 10 MHz, which is higher than the chips internal oscillator is rated for, the music plays exactly how I want it to.

Written like that, It looks like some kind of mismatch ...

Using " FREQUOUT " when defining the correct osc frequency gives the correct frequency, or close to it ... nothing else !

so, as it seems to be PBP ... may we see your source program and especially the config section ???

You can overclock, at your own risk.

Yes, but how to Re: overclocking internal oscillator?

Maybe overclocking about 1% with the osctune register?
