Overclocking The C3000

Looking good! Got my text messages at boot time.

Will try the overclocking next.

Oh, and how do I get rid of the CG Silicon splash screen?

Thanks!

good !  

Oh, and how do I get rid of the CG Silicon splash screen?

don't know that... it's part of the process of starting the Qt environment and i believe it's a binary included in the "qpe" startup script. maybe a "master of Z" can help on this... not me  

as i've already said, don't forget to increase VCORE before increasing freqs
in the other way, don't forget to decrease freqs before decreasing VCORE

I couldn't get the applet to work so I manually changed the VCORE and CCCR numbers and rebooted.

Everything is working fine so far. I even playe a 30 MB video and no freeze, no screen flicker. Maybe I'm just lucky?

Is there a way to verify that my Z really is overclocked?

and rebooted.

well i think that the default values are used when you reboot.

Is there a way to verify that my Z really is overclocked?

Code: [Select]

#cat /proc/zaurus/CCCR
#cat /proc/zaurus/VCOREand check the values

i feel like the values are taken dynamically when changing them in the 'proc' files.
i've noticed differences in the use of my debian X/Qt environnement... menus are getting much faster...

[totsubo]

Hum ... if the values are dynamic that sucks ...

Wonder if there is a way to make them permanent?

Just a quick test to see if upping upping the VCORE and CCCR values really does overclock the CPU. And the answerr looks like YES!

Running this loop:
for (( i=0; i <= 10000 ; i++ )); do echo $i; done

CCCR:  2000218
VCORE:  0e
time: 7.390s
time: 6.731s
time: 6.745s
time: 6.740s

CCCR:  2000210
VCORE:  0a
time: 11.536s
time: 11.350s
time: 11.218s
time: 11.180s

This question is so obvious that it is silly but here goes.  How useful is overclocking on the C3000?  What can you now that it is overclocked that you could not do before?  

This is not a troll.  If there is something nifty waiting at the end of this trail, I'll pull my Z out and try to whack a new kernel into it.

Just for context, I have the stock kernel and ROM running on mine and won't be using Debian because I need to keep the Japanese data entry functionality.

To be honest there isn't much so far. The one thing I have noticed that is nice is that menus pop up faster.

As for the Japanese input I didn't lose that. I had before the new kernel and still have it.

Do you have japanese input now? I can't see how changing kernels would affect it.
