tried current QCPUFreq ..used slider to 1000...rebooted..
message- unexpected reboot occurred.your custom kernel settings were not loaded...
It will "upgrade" your QCPUFreq with the updated script by marmistrz, no need to uninstall it first

didnt understand

EDIT- tried again and again...
mv .../QCPUFreq.helper /opt/usr/bin/QCPUFreq.helper

still same error..i think the post says in power version 50, further tweak is needed to keep it stable...isnt?
... is a symbol. It means that if you have saved the modified helper to /home/user/MyDocs/ (internal storage), you should do

Code:
mv /home/user/MyDocs/QCPUFreq.helper /opt/usr/bin/QCPUFreq.helper

I think you have saved the script somewhere else. If mr_pingu's build is stable it might be easier for you to use it.

I would say, follow my instructions regarding the .deb file I linked before in this thread. The result is the same as I used the same file but I made it easy for other users...

Ofcourse you may do it marmistrz's way but then you need to save the file marmistrz gave you in MyDocs, first

Just wondering, did you just swap the scripts for the deb file?

Yep, the "dirty" way ;)

And bumped version number by editing control file, IIRC

Well not all n900 are stable at 900-1150mhz range only few manages to run stable at 1ghz and beyond.
You should try lower frequencies 850mhz and below..

done
pasted in MyDocs
command copied in terminal
last lines

setting up qcpufreq (0.4.5-1)...
processing triggers for catorise...
#####################/home/user #

is it all ok?

EDIT- slider to 1100....rebooted.....im a new guy in N900...overclocking may not be good if not an expert..isnt? but 250-750 is safe ...isnt??with good battery too...

now settings icon needs 3 tap to open......some error has happened...

Re: [Announce] QCPUFreq - modify your maximum CPU speed
 
OC can be dangerous, some phones can't handle more than 1000. Also overclocking is not really needed as it won't make the N900 that much smoother as IO is the bottleneck in terms of performance. For instance, I almost never overclock as I don't think it will gain much. I only overclock when I try to shoot a 720p video and some emulator, like dosbox. Generally 750 is safe, but every frequency you will go higher can reduce your CPU lifespan drastically. The SoC found in the N900 is meant to run at 500mhz, Nokia already overclocked it to 600mhz.

So my advise is to leave it at 600mhz, *unless* you really need more cycles for eg gaming. For general use it isn't recommended, of course you can decide yourself to run fulltime on higher frequency and some here also do that, so I don't say it is dangerous but 1 thing is sure, higher frequencies can/will decrease the lifespan of the cpu.

said in so simple words....i respect it..thanks a lot....i understand...
only when i do hard gaming or such stuff i would use 800MHz.
or else leaving it at
min-250
max-550
ok?not even 600.....

BTW why is my settings icon taking 3 taps to open???

I only use OC for Easy Debian :) This is one more situtation when OC is nice.

Nah, 550 would hurt performance, Nokia isn't stupid so I guess they didn't pick the 600 random ;)

Just press once and wait, also make sure you press the button right; I caught myself "miss"pressing icons sometimes and nothing happens. Also settings app sometimes have to load for 1-3 seconds

@marmistrz: Well, you get the idea ;)

Well, Nokia is stupid. Who clever would (try to) kill Maemo/MeeGo? :)

Nokia is stupid now, at times when designing the n900, they weren't stupid ;)

This is my first deb package, be careful. It installs and works perfectly on my phone, so enjoy but be warned ;)

This package was based on marmistrz's script where he noted this:

So I'd like to know if the patched QCPUFreq works ok with KP51 and later. Thanks!

Seems to work ok. Overclocked step by step to 1150 and no crash. So it should be ok. You might try 1000 & SR to check if it'll be better

I believe your not supposed to use frequencies over 900 with SR. It's not stable on all devices.

Just read the wiki, but is that info correct?

Wasn't that problem independant from frequency? I used to have trouble with SR on one of my machines, but after KP50 it never gave me any trouble again. Than again, I never OC above 900 anyway.

Wiki is correct AFAIK.
There is also the other issue of not using custom voltage profiles with SR on. Custom profiles "Undervolting" are considered "legacy method" and shouldn't be used with SR on.

SR doesn't cause an instant crash with 950, did with 1000 when I was doing the script

UV + SR = crashes

SR = Undervolt SR does undervolting on the go and overrides your custom set undervolt. However sometimes between switching it uses your set voltage and can cause a crash.

Officialy SR (kp 50 and above) only goes to 900 as max, some devices can just handle 950 - 1000 on the voltage calculated for 900Mhz.

Sorry, I didn't say clear: UV profile + SR = crash...

Can you try to patch the source package and upload it to extras-devel?
