Re: Overclock the N900?
 

Andy214

please read the entire thread....

whilst using -k it only flashes the kernel, no files, apps, messages, porn, contacts, bookmarks will be lost



Canson

make sure ur typing

flasher-3.5 -k zImage-930mhz -f -R

not

flasher-3.5 -k zImage-900mhz -f -R

and if you have downloaded the one with DSP clock speed increase its

flasher-3.5 -k zImage-900mhz-500dsp -f -R



if you are getting this wrong should you really be doing it in the first place...

Re: Overclock the N900?
 

I think the code is like
flasher-3.5.exe -k zImage-930mhz -f -R

Re: Overclock the N900?
 

After running for 1 day 2 hours at 900Mhz, I just noticed the phone was off.

I initially thought it was the battery that had run out but decided to verify this.

I took out the battery and placed it back in and it booted right up. The phone was very warm ( room temp is currently 34 degrees C ).

cat /proc/bootreason showed "pwrkey" but I know I did not accidentally press the power key.

The last thing I remember doing was downloading 6 new episodes in Gpodder with Tweego opened in the background.

It was running at 500Mhz (60% load when I last checked)

Have resumed the downloads and am monitoring closely.

NB
This is the first unexpected shutdown I've experienced since purchase.

Re: Overclock the N900?
 

i just wrote like you said but still dont find the file..


sajman could you plz upload your file???

that with 500 dsp.

Re: Overclock the N900?
 

can someone send me the 125-900mhz?
thx

Re: Overclock the N900?
 

anyone else noticed the 930mhz/500mhz dsp idles quite high compared to the 900mhz???

i noticed that even when idle the 930mhz will be sitting in a high frequency range surely meaning more wear on the processor and creating more heat and worse battery

i personally think the 800mhz or 900mhz is safest depending on what you use your n900 for if you need the extra power great but i would think that 900mhz setting would be more the adequote for most users if not all users

for the gains you get from the 930mhz compared to the 900mhz and the idle speeds of the two id stick with the 900mhz :-)

just what ive noticed over the last 24 odd hours

Re: Overclock the N900?
 

tbh i think 900mhz is over the top, thats a 50% increase, dnt that seem to much?
not that im complaining lol

Re: Overclock the N900?
 

yep it does mate

i thik its a case of finding the balance between power and lifespan of components and battery

to be honest i think 800mhz worked pretty well however with 900mhz it idles at a reasonable speed 125mhz -- 500mhz depending on processess running and that is under stock speeds still

it just has the overhead space if needed

like you say though its a 50% increase which is a large increase whatever way you look at it

id think 800mhz would do and would probs be better on the battery

lets face it the n900 is powerfull anyways its just giving it that extra room for manouver we need to stop it maxing out and juddering etc in places

Re: Overclock the N900?
 

My phone switches off by itself sometimes (only the radio) if I have been using too much 3G for longer periods. That happened before overclocking though.

Re: Overclock the N900?
 

same here. mostly it clocks down to 500mhz, sometimes 125mhz. i think i'll switch back to the 900mhz image...

Re: Overclock the N900?
 

Can we use kernel-flasher(from the app manager) to flash these kernels?(i have a faulty usb port and dont trust flashing my device with Maemo Flasher 3.5)

Edit: and if we can...than how? (forgot to add this very important info:D)

Re: Overclock the N900?
 

It did feel hot when I noticed it off...

Anyway I have finished downloading the 6 videos (podcasts) without further problems. Am watching them now.

Re: Overclock the N900?
 

I've actually experienced this too with stock kernel a few times. The phone beeps that "battery dead" then it takes 5 seconds and shuts down. Then I put it back on and the battery meter shows ½ battery and it works without a problem.

Re: Overclock the N900?
 

or kexec-tools?

Re: Overclock the N900?
 

sajman,

Thanks! Actually, I've read few pages for quite some time, there're too many post and it's quite messy, probably I've missed the part about "-k".

Btw, is there a dedicated thread for this flashing guide in detail? All the flashing guide I found over the web is about flashing the firmware.

Perhaps the thread starter can also summarize some instructions in the first thread including warnings in red bold text.

Thanks again! :)

Re: Overclock the N900?
 

Nope, my problem was different - the radio dies but the phone reports it working and when people are calling me, they get free signal but the phone doesn't ring on my side. If I try to call someone it reports some strange error and fails. A reboot fixes everything.

Re: Overclock the N900?
 

flashed 850mhz/450dps, can get in OS, but random reboot happens while watching youtube, reflashed to 850mhz, very stable, no problem at all watching youtube while bt downloading in background. so i just wondering is there any chance for a 800mhz/450dsp or even 800mhz/500dsp?

thank you very much.

PS. thank you all again for such a great thread.

Re: Overclock the N900?
 

Well thanks to this wonderful thread i have been able to improve the performance of my phone :) I flashed to the 825mhz kernel and i have just managed to watch trueblood on my phone via tvshack, this was all on the tv-out, so i can watch tvshack on my 40" samsung lcd! Happy days!

Re: Overclock the N900?
 

Edit: and if we can...than how? (forgot to add this very important info)Well to answer my own question you can't it has to be a "fiasco zImage"

dose anyone know how to convert to a "fiasco zImage"?

Re: Overclock the N900?
 

very interestin thread have read through it believe it or not...
I have waited for overclocking the N900 but didnt have the necessary knowledge ;-)

However i want to run experiments on the battery consumption using battery graph. I thought about testing the 125-800mhz and 125-900mhz kernels in different scenarios ( i mean like video playback/audio playback/web browsing/streaming/standby)

Please suggest your applications of interest and what kernel mods you'd like to have tested. I dont want to test extreme settings though, just the moderate ones which may be better than the original setting in everyday use.
Also give me advise which applications would be strongly affected by increased processor speed but without dsp speed up.

If battery life will remain pretty much the same with moderate oc i am lookin forward to use them constantly. btw big thanks Letho!

Re: Overclock the N900?
 

I agree, posted my experience before and its kinda same as yours ... Returned to 900 from 930 ... Will test 1025mHz though ...

Re: Overclock the N900?
 

please also make call, this is what makes the phone warm/hot.

waiting for your result, i have 900mhz

Re: Overclock the N900?
 

How fast do you think it will take to install Mac OS X 10.3 now? 1 1/2 hours? :p

Re: Overclock the N900?
 

my video on youtube has got over 900 views lol

Re: Overclock the N900?
 

can somebody upload a step by step guide of how we will overclocked the device . I have read all the thread but i could not find anything.
From what i have read 125/900mhz is the best option and it is quite stable.
have anybody tested with 1 hour navigation or 1 hour psx4all continious playing?

Re: Overclock the N900?
 

Any videos featuring Flash games performance after overclocking? maybe miniclip games?

Re: Overclock the N900?
 

Guys is it posible so have a modified kernel and some one makes a overlocking app that allows user to select what speed that want via terminal or gui?

i'm not a programmer so any takers on the idea?


oh is there any way to get firmware information back in "about"?

Re: Overclock the N900?
 

hmm strange, mine on conky, even with bounce and banner in back running... clocks at 125mhz idle...
and when just music is playing it goes 500 to 930 mhz

edit : music playin' on speakers uses more cpu than with earphones... finally it can clock to 250mhz on speakers too

Re: Overclock the N900?
 

:eek:mine with mp3 playing is 60-75% @900mhz


ok its better now lol

Re: Overclock the N900?
 

I think you should put the method, links and relevant informations in the 1st post as I don't think anyone should have to go through all the 60 pages of this thread when looking for something that could easily be consolidated in the 1st post...

Re: Overclock the N900?
 

Depends what you mean. As mentioned above, this only tweaks the range of speeds available for the N900 to automagically use so as long as its stable there should be no reason to alter it.

I had initially thought it would be easy to choose the speeds as there is a file /etc/pmconfig that would appear to configure the speeds. Obviously this is not the case however as that file still says 600Mhz max but with the 900Mhz kernel it is happily using 900Mhz max. So anyone got any clue what that file is about?

Re: Overclock the N900?
 

According to the front page news, I can req the scripts via PM. I do not know who to PM so I am requesting them to be PM'd to me.

Re: Overclock the N900?
 

You can do the flashing from the n900 without the need of a pc (but if something goes wrong you do need a pc). I did it succesfully with the following command (as root):

most images have links to the download in this thread

Re: Overclock the N900?
 

aha i see i did

and it would tell me that the bin wasint a FIASCO

thanks alot

Re: Overclock the N900?
 

Hello all,
I've been testing my N900 tried to all kernels (since 600 to 930 MHz) during 2 hours each one, and i have no issues with no one.

Off course 2 hours is nothing to test all possible freezings, battery life and other issues, but for now i'll stand on normal 900 Mhz Kernel.

What most of us want is a kernel that boost our n900 performance, not to drain so much battery life, and with stability ! Right ? (or not..lol).

So..lets continue put here our testing results.
At the end we can have a good % of a good kernel to apply on most cases.

For now, working with 900 Mhz kernel ( a little..afraid of..increase 50%..ahah..this is loving stuffff, thanks a lot for all developers! )

Sorry for my little poor english,

Regards,,
