Re: Overclock the N900?
 

You can separately adjust the CPU and DSP. Overclocking the DSP didnt really make any difference I think, as I dont have any good way to test it. I put it from 430mhz to 540mhz. Overclocking the video accelerator is going to be a much trickier part as I dont think its driver is open source and not really that useful just yet.

Re: Overclock the N900?
 

Can some1 pm me the files for 800 and 1000mhz overclock?

Re: Overclock the N900?
 

I think the DSP is mostly used for media processing, encoding and decoding H.264 for example. Testing 720p (or 1080p @1020/540 :)) playback would probably be a good benchmark, but I guess the applications and codecs aren't ready for that at this point?

Re: Overclock the N900?
 

Lehto - would you be willing to email me the files for flashing to 900mhz. I'd appreciate it very much, nd4001 at google mail. Thanks for your work

Re: Overclock the N900?
 

keep up the good work lehto mate

:-)

Re: Overclock the N900?
 

yeah i'd like to know if that could let us play 720p videos !!!

Re: Overclock the N900?
 

Hey!
I got only my laptop with Ubuntu 32bit with me currently and as i'm total noob with Ubuntu and Linux in general i would appreciate if somebody could post detailed instructions.
I do already have the zImage i need.

Re: Overclock the N900?
 

I'm interested to know what speed difference you notice using flash websites.

For instance is grooveshark.com usable?

Re: Overclock the N900?
 

without dsp OCed, it starts it, you can hear smthg for less than 1 sec and then "buffering" (n900 OCed 900mhz)

Re: Overclock the N900?
 

lehto,

Could you email me the kernal for operating at 800 mhz please?

I fully understand that worst case it'll destroy my N900, but from what I've done before and what I've read, 800mhz seems a pretty safe overclock for the N900.

Would love to try anyway.

cheers,
Dave

Re: Overclock the N900?
 

maybe somebody share files? why only pm?))))

Re: Overclock the N900?

flasher is there...

1. Put phone to update mode (phone off, Press and hold U plug in usb cable) then run

2. flasher-3.5 -k zImage -f -R



because it can damage your phone. u cant just go around flashing kernel images onto your phone willy nilly

Re: Overclock the N900?
 

yet the guy you just gave instructions to, on how to flash, clearly has never done it before.

Re: Overclock the N900?
 

Well i have flashed my N900 using Vista couple of times, but i have used Ubuntu for 10hrs so i'm not exactly mastering it yet ;)
Imo it's more about that people will accept that what could happen if all goes wrong and imo in that sense it might be better that the zImages aren't flying around too much :)

Re: Overclock the N900?
 

i'd like to try the 125-800mhz and 125-900mhz kernel, can any pm me the files please? i do get the risks.

thanks.

Re: Overclock the N900?
 

fair enough - I just figure that if someone is able to find and install Maemo Flasher, and knows enough to search for a zimage, that they're probably well aware of the possible ramifications.

of course, admittedly, i'm just frustrated that I have to wait for the files until they're shared somewhere or I get PM access.

Re: Overclock the N900?
 

PPL, please, upload those files ... Is it not more convenient then to respond numerous PMs? Just add some "your own risk" stuff ... anyway, everebody here knows they (we) can brick that thing up ... so what?

But if you still dont want to post the files, then Im interested in a kernel, ideally scaling 125-800mHz ... Thank you!

Re: Overclock the N900?
 

hmm i have the same problem with PM, no access :( please, please, please, upload it somewhere.

Re: Overclock the N900?
 

Can I also have a kernel scaling 125-800mhz?

Thanks.

Re: Overclock the N900?
 

I have just flashed mine to the 900Mhz kernel from Lehto. (125-900)

Here's some of my quick comparison. Before flash and after.

------600mhz--------

250mhz 12% during idle
500mhz 9% during charging

35sec HAM launch till downloads show up
20sec daum.net via MicroB
08sec sygic map loaded
09sec time to show tweego login screen

-------900mhz--------

125mhz 14% during idle
500mhz 8% during charging

26sec HAM launch till downloads show up
12sec daum.net via MicroB
06sec sygic map loaded
05sec time to show tweego login screen

Re: Overclock the N900?
 

that looks sweet, can a app be made or is flash needed?

Re: Overclock the N900?
 

Nice, its look useful for me. Can anybody send me kernel with 125MHz-800MHz ? Thx:D

Re: Overclock the N900?
 

i'd like to have a fiddle too please.

be nice if someone could pm me the kernel.

thanks.

Re: Overclock the N900?
 

hey jakiman,

can u pm me this kernel, its exactly what im looking for and can't pm lehto...

Re: Overclock the N900?
 

is this a part flash? say i flashed mine to 900mhz and decided to restore stock clock then i can do that without full flash?

Re: Overclock the N900?
 

Just reflash the original kernel.

Re: Overclock the N900?
 

flash a 600mhz kernel

Re: Overclock the N900?
 

can some one share 900mhz flash file with backup of original 600mhz?

on the "about" of settings does it still say phones version or unknown?

cheers

Re: Overclock the N900?
 

Sorry about this but I had to remove my kernel files to make space for other stuff. I hope everybody who used them has the files backed up.

Re: Overclock the N900?
 

hey lehto both kernels are named 700

btw can u pm me the 125-800 kernel? i want to experiment a bit i know the risks

Re: Overclock the N900?
 

Okay so what do i do in the flasher tool then?

Re: Overclock the N900?
 

make sure you charge your battery to full before flashing incase!

also for those who have flashed, how is the battery life?

Re: Overclock the N900?
 

can i update to pr1.2 with no problems if i have the 700mhz kernel flashed?

Re: Overclock the N900?
 

can you provide original please incase i want to go back.

thanks

Re: Overclock the N900?
 

had 800mhz for about 3 hours now, tryed loading some iso files in psx4all, browsed a bit, streamed some youtube... still full battery!

Re: Overclock the N900?
 

MAKE SURE BATTERY IS FULL

make sure you put the kernel file into the maemo flasher folder on pc in windows it usaully c/prgramme files/maemo/flasher3.5

turn off n900 and hold u button on keyboard , connect the handset to the pc , a usb symbol should appear in top right of phone screen

on windows run maemo flasher as admin then run the command

flasher-3.5.exe -k zImage-800mhz -f -R

(please note that youll have to change the zimage-800mhz to whatever kernel your using ie zimage-900mhz or zimage-700mhz)

it should take approx 10 seconds max

make sure you put the kernel file into mameo flasher folder on pc so the flasher can find the file

PLEASE NOTE YOU DO THIS AT YOUR OWN RISK AND THERE ARE RISKS INVOLVED , PLEASE DO RESEARCH BEFORE FLASHING YOUR KERNEL ON YOUR N900 AND ONLY DO THIS IF YOU ARE SURE YOU KNOW WHAT YOUR DOING , IF YOU DONT I ADVISE NOT DOING IT AT ALL

Re: Overclock the N900?
 

Yeah... will upload it there soon.

No idea, If you do it over the NSU then yes.

Re: Overclock the N900?
 

I've just put on the 700mhz patch and even that speed increase has impressed me. Youtube videos load a lot faster and much more smooth.

I think ill keep it at this for a while and wait for the next one just in case, even tho i would love to try it.

Re: Overclock the N900?
 

ive read that this will roll back to previous kernel mate but iam not sure maybe a member could confirm this

''you can reinstall the stock kernel by typing apt-get --reinstall install kernel kernel-flasher.''

Re: Overclock the N900?
 

so if flashed via nsu to get the new update lehto the overclocked kernel will remain?? intresting , thanks
