I have a strange problem with under/overclocking:

Always when I try another profile than default (starving and XLV tested) the phone starts to stutter and is slower/less responsive even with overclocking (tried it up to 850Mhz) than with default settings!
Now I have overclocked my N900 up to 750Mhz with the default settings (kernel-config limits 250 750) and it doesn't have this stutter effect but I cannot save energy with low energy profiles.
Which setting in those profiles could cause this and how can I fix it?

I tried to get this working but even after a reboot it doesn't do anything. What could be wrong?

Thanks for help.

stutter is a normal......problem, maybe try your freqs to 500/xxxxMHz

No, it is not the normal stutter it is something worse. Mobile Maps is not able anymore to speak fluently and the phone feels slower than with the default settings which means there must be something wrong with the tested profiles (starving and XLV) on my phone because it doesn't have this stutter effect with default mode and overclocking.

Your particular unit probably just isn't very tolerant of the lower voltage profiles same as how some units don't tolerate the higher clock speeds well. Depends on your unit, the luck of the draw.

Try loading the 'lv' profile. It's the least aggressive one and should be ok. Of course it offers less potential power savings, but honestly I haven't seen really significant, noticeable power savings from any of the power profiles anyway - but maybe that's just me.

now i get it......XLV and starving has too low voltages that brings quite problems (stutter, lags, reboots video cam shut down etc), but i believe some of the overclockers has able to make a work around which is beyond my understanding. so change your settings to a higher voltage (like LV and the default).

i always have the stutter effect in XLV. and unexpected reboots in starving. but i always set the settings to default when playing music.

EDIT: Crashdamage has the absolute point.

Thanks and what about the "ULV" profile?

the UL has a bit lower voltage on idle (250MHz) so not so different in XLV. but most overclockers use XLV, even myself use XLV. stutters can be minimized but setting to a higher voltage

So LV should be "stable" (without extreme stuttering) while ULV would behave more like XLV and starving, right?

And what about my second problem?

BTW, i'd like to have different max frequency while the phone is plugged into usb/charger

there is a possibility that it could be stable. you can always try.

the unresponsiveness might also due to low voltages (but i am not certain). try re-booting your device before you try your settings
