anyone????

Re: Overclock the N900?
 

yeap, i'd like to know for the dsp... would maybe be useful for psx4all !

Re: Overclock the N900?
 

both work great i know that much

Re: Overclock the N900?
 

looks similar to my patch
http://maemory.com/N900/overclock/overclock.diff
I guess I should also change set the second occurence of max_freq in cpu-omap.c

Re: Overclock the N900?
 

iplayer used to work okish fullscreen @ 600mhz. Now mine is clocked at 800mhz everything else is alot faster but iplayer is unwatchable.

Any ideas?

Re: Overclock the N900?
 

Your patch is problematic, since the OPPs are not only indexes, they have a physical meaning. See my changes in smartreflex.c for more details.
Also, the same indexes (selected by the mpu table) are used to access the mpu and the dsp tables, so they must be the same size (or use some other hack, as I did in the file resource34xx.c).

Re: Overclock the N900?
 

The dsp runs at 430 MHz by default.
No, it does not affect emulators. It's utilized by some audio and video codecs and telephone stuff.

Re: Overclock the N900?
 

how did you oc the dsp ?? and does it improve psx gameplay ???

Re: Overclock the N900?
 

You musn't be afraid. If you want a secure PR1.2 upgrade, the only thing you have to do is reflash again the N900 with the stock kernel (600Mhz) and then, flash it with PR1.2

Also, I think there is no problem with flashing directly the overclock kernel with the stock PR1.2 since the update comes with a newer kernel version. Sorry if my English is very bad!

Re: Overclock the N900?
 

thanks. I missed the reference in smartreflex. The LUT seams to reasonable.
yes, my tables have the same size.

Re: Overclock the N900?
 

omg! just flashed with 900mhz, and i am impressed ! thats how the nokia shuld have been from the start! the maps are running sooo smoothly! the whole sistem is snapy! good work!

Re: Overclock the N900?
 

NFS 3 in PSX4ALL

-Overclocked @ 125 - 930mhz , 500mhz DSP
-psx4all 0.3.9 (cycle mod x 10 and all other settings off/minimum)

Re: Overclock the N900?
 

hi, i got default web browser problem after flashed with 750MHz kernel, I cant start it up anymore even with a reboot.

does anyone knows why?

Re: Overclock the N900?
 

So I've been reading through this thread and I can't find the answer to two things:
How does it affect battery life? (as in, when idleing and so forth)
Does the flasher reset everything and delete all my apps (I know mydocs/calender/contacts will be unaffected since I already reflashed from the UK firmware to the Global one)

Re: Overclock the N900?
 

links don't work :( do someone have the 125 - 930mhz , 500mhz DSP (stock 430mhz DSP) kernel ?

Re: Overclock the N900?
 

When you flash it with -k parameter (like is done in the guide of the post), you only flash the kernel, so, you don't loose any app. You only replace the kernel image. It is a transparent process for all the information stored in the N900. You don't need to reinstall anything and all your information is going to be like before flahsing.

Re: Overclock the N900?
 

unsure about batt life, it idles at half speed now, and some ppl think that the fact the higher mhz will posibly help batt life too as calculations will be done quicker.
obviously if its maxed out for long periods it will adversely affect battery

the flasher does not reset things, it only takes a couple of seconds and just turn the phone on and run conky to see new mhz.

Re: Overclock the N900?
 

I've answered these questions multiple times....
For me, battery life is slightly better as the phone is mostly idling at 125Mhz .

No apps are deleted during flashing

Re: Overclock the N900?
 

It doesn't affect battery life much since it can idle @ 125 now.
If you reflash a kernel it doesn't reset anything, all apps, contacts, calendar entries will stay.
Backups are recommended but it won't touch anything except the kernel.

I guess simonfzhao had same kind of issues w/ microB, check this: http://talk.maemo.org/showthread.php...600#post594600

Re: Overclock the N900?
 

Thanks for mentioning this which I think I will try since I don't have a PC nearby (if something goes wrong I just have to wait until I get my hands on a pc)

Before I go on I would however like to hear what the difference is between the fiasco-flasher (in /usr/sbin) and the flasher (in /usr/bin). Should I rather use the latter?

And now we are at it with questions I might as well throw in another one: From the wording of the wiki it seems that there is no flasher-3.5 for linux 64 bit. Is this correct?

Thanks in advance!

Re: Overclock the N900?
 

Yes, but the 32-bit flasher works at least in Ubuntu 64-bit

Re: Overclock the N900?
 

Everytime getting this error "waiting for suitable USB device".I'm running Windows 7 64 bit.Why?

going to play around with this for a couple of weeks whilst im on holiday, going to take some screen shots of battery graph.

hopefully compare with someone who has got 750, 800, 850 and 900 on their system! :D

N900: Windows 64bit (Vista&7)
According to this post, windows driver signing can cause problems. You either need to turn on the loading of unsigned drivers or boot your computer to whole another OS.

[edit] Option 1
Disabling signed driver detection is done by choosing the option "Boot without checking for signed drivers" (or something similar) in the boot-menu. To display the boot-menu press the "F8" key as soon as the windows boot process starts. The rest of the process is similar to XP.


[edit] Option 2
Alternatively you can permanently disable driver checking via command line manager. There are good instructions for windows 7 available [1]

[edit] Option 3
You can use [2] Microsoft Virtual Pc but when you connect your phone, press the "usb" button and select your device.

[edit] Option 4
An alternative approach is to either download Ubuntu LiveCD and burn it to cd or create a persistent installation to usb disk. After that you must get (another) usb stick where you will download maemo_flasher-3.5_2.5.2.2_i386.deb -file (versions may vary) and firmware files needed for reflashing. Additionally one can save this page to usb stick just in case.


After that you only boot your LiveCD or persistent Ubuntu, install Flasher (doubleclick the file should work fine) and after that follow instructions from Linux - chapter.

[edit] N770/N800/N810
Internet Tablet users can go to the appropriate support page for their device (N810 WiMAX Edition, N810, N800, or 770), download and install the Software Update Wizard, run it and follow the on-screen prompts.

Re: Overclock the N900?
 

Thanks you guys.

Yeah, when I was talking about the batt life I meant while at regular use. Obviously at full load its going to drain 10 times quicker.

I really wanna try the 800mhz OC now :D Do you guys recommend using the one with DSP OC too?

Re: Overclock the N900?
 

DSP helps with youtube etc.... but higher clock speed helps with that anyway! haven't tried any HD footage yet! may go for it

Re: Overclock the N900?
 

I've Ubuntu 9.10 32 bit also and I've installed Flasher 3.5.Now tell me how to flash the kernal?Where to put the zImage file??and which code to use?

Re: Overclock the N900?
 

thanks a lot for this nice work !

Re: Overclock the N900?
 

i put the zImage in the same folder as the flasher3.5.exe
Put phone to update mode (phone off, Press and hold U plug in usb cable) then run

flasher-3.5 -k zImage -f -R

zImage being the enitre name of your zImage

e.g.
flasher-3.5 -k zImage-900mhz -f -R


look though this entire thread before asking again.... only fun helping out a certain amount of times. It has been explained several times. Also do it only if you accept you can bugger up your phone!!

Re: Overclock the N900?
 

Sygic Mobile runs now super smooth 24fps N900 @ 930Mhz :)
No side effects (yet), cool :)

Re: Overclock the N900?
 

@sajman
thanks for helping.I want to flash in Ubuntu 9.10 as in Windows 7 it is not working for driver issues.Sorry for asking it too many times.

Re: Overclock the N900?
 

Supported operating systems

Linuxes (Debian installation package available for Debian based Linuxes and tar ball for others)
Windows XP with SP3, Vista with SP2 and Windows 7 (but not 64 bit, see Troubleshooting)
Mac OS X 10.5 Leopard and 10.6 Snow Leopard



suppose youll have to wait for someone who used Ubuntu to help. soz im no good on this one!

Re: Overclock the N900?
 

Did you really put the phone in update mode?

as mentioned before:

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

Re: Overclock the N900?
 

sajman mine says: No such file or directory:(

I already put the file in same folder as flasher.

and wrote like you said in cmd.

It worked yesterday with 900 mhz. But today i want try the 930 mhz file:(


EDIT: 900mhz file works in cmd to flash,but not the 930mhz file.

Can someone upload your 930mhz file??

Re: Overclock the N900?
 

The firmware (.bin) file is required too right?

Read from some sites, flashing will remove all apps installed, apps catalog, settings, etc. But here, I read someone mentioned all are intact?

Can someone confirm this?

Thanks!

Re: Overclock the N900?
 

Yes I put the phone in update mode
