Re: Overclock the N900?
 

i want to use this one too ive been running 900mhz stable for 24hrs now

the link is broken

can anyone reup it

Re: Overclock the N900?
 

It's not broken: http://www.saunalahti.fi/crailt/zImage-930mhz-500dsp

I've flashed it and it seems to be a little bit slower than the 900 MHz one but that could just be me

Re: Overclock the N900?
 

125 - 930mhz , 500mhz DSP

http://www.saunalahti.fi/crailt/zImage-930mhz


seems faster to me??

maybe its more stable, but not quite as fast?

Re: Overclock the N900?
 

Does your cpu ever run at 750Mhz? Lehto noticed it never selects the speed above 600Mhz except the highest speed. Maybe he's right, maybe not but would love to find out from more than 1 person if possible.

Re: Overclock the N900?
 

thankyou so much :-) big smiles

Re: Overclock the N900?
 

125 - 930mhz , 500mhz DSP is my fav so far, tuxracer works great and psx4all runs SWEEEEEET

standby for VIDZ

Re: Overclock the N900?
 

ive done modding thru ssh over wifi, does that count??

Re: Overclock the N900?
 

930/500 DSP works fine for me, does someone know a good tool to benchmark the n900 ?

Re: Overclock the N900?
 

mm having problems flashing 930-500mhz image pc recognizes it as a text file .

flasher doesnt see the kernel at all

Re: Overclock the N900?
 

No, to really validate the safety of the overcloking you need to transfer files from and to the device, a bit like a burn test but for files.

Re: Overclock the N900?
 

930--500dsp

loaded fine and seems ok will have to test for more though 900mhz was really stable on mine though

Re: Overclock the N900?
 

These links need to be fixed.......


125 - 850mhz , 450mhz DSP (stock 430mhz DSP)
zImage-850mhz-450dsp

125 - 930mhz , 500mhz DSP (stock 430mhz DSP)
zImage-930mhz-500dsp

Re: Overclock the N900?
 

Now we need a cpu burn in app for the N900. =)

Something like Prime95 or OCCT to test the stability at full load for 5mins, 10mins etc.

Re: Overclock the N900?
 

delete the ".txt" file extension.

Re: Overclock the N900?
 

i would but the .txt extension isnt there but its still recognised as a txt file ?

Re: Overclock the N900?
 

thats what i did... put files on my n900 such as modified keyboard mapping, custom LED/vibate, custom app icons, custom status area icons etc etc etc

Re: Overclock the N900?
 

By default, Windows is setup to not show extensions of known file types.
You will need to disable this feature in explorer options to see the extension.

Re: Overclock the N900?
 

cheers jakiman worked a treat

Re: Overclock the N900?
 

Im just trying some other speeds, started out with 800mhz, now trying 700mhz and next will try the 750mhz and then settle for 1 of the 3, but going from 800 to 700 theres a noticable speed decrease, so will flash the 750 file in a bit after sunday roast.

Re: Overclock the N900?
 

I'm talking about big files like a several GB zip file that you transfer to and from the N900 and then decompress it to check if there was any corruption.

Re: Overclock the N900?
 

I've just done the following.....


zipped 2 100MB files into 1 zip file,
transfer the zip file to the phone,(mass storage mode)
extract the zipped files from the phone .

All in a few seconds and with no errors!

Re: Overclock the N900?
 

I am now on 930Mhz/500dsp ... after using 900mHz variant I have a feeling that this 930 underscales a bit worse ... 900 was on 125 most of the unused time, 930 is scaling up in the same situation ...

Re: Overclock the N900?
 

Tried this with 6 films in a zip file, total size was 4.1gb, copied via usb in mass mem mode, copied back and forth 3 times, zip file remains in tact, im only running the 700mhz kernel tho at the moment, will try later with the 750 and 800 mhz

Re: Overclock the N900?
 

I'm interested to see if anyone has less frame drops etc recording a video clip... preferably a panning shot or two :)

*Or, would overclocking have little impact on the recording quality?*

Re: Overclock the N900?
 

I find the phone to stay warm with these setting. it was normal with the 900mhz file. I some what assume it is related to the higher dsp settings. I am going to the 850 on next to see what it is like.

Re: Overclock the N900?
 

you should see nfs 3 on psx4all @ 125 - 930mhz , 500mhz DSP !!!!!!

Re: Overclock the N900?
 

Tested a 1.4GB zip file containing 2 700Mb movies.

Copied it back and forth multiple times (PC <-> phone mmc<-> to PC)

Transfer speeds (8.4Mb/sec write, 9.4Mb/sec read) : 16GB card

No errors! (zip error test with winrar)

Re: Overclock the N900?
 

So you think 900MHz is better then 930MHz for the battery life?

Re: Overclock the N900?
 

Thanks for that guys, that really useful :)

Re: Overclock the N900?
 

I'm now 23hrs uptime @ 900mhz ..... I've been using the usb cable to run the transfer tests so some charging has taken place ( a couple of minutes ) since 00:00GMT(last full charge).

I'm at 57% now, having watched smallville (full screen in browser) and run a barrage of other tests.

I cannot see any difference in battery usage.... I might lean towards improved actually.

Re: Overclock the N900?
 

I downloaded and installed easy debian... its working perfectly..

there is decompressing etc in the process

Re: Overclock the N900?
 

Overclocked mine to 800Mhz. Youtube is much more smoother, not to talk about Media Player... very nice!

Re: Overclock the N900?
 

could someone explain the DSP??
is 930mhz 500dsp mean 30mhz more than 900mhz? or is it a different story??

what dsp is the 900mhz and the 800mhz ones at? and whats the difference?
thanks

Re: Overclock the N900?
 

very rarely post because i never have much to contribute.
1 week ago i was annoyed at how laggy everything was and my n900 had slowed to a halt. so i reflashed it and wow it was all zippy and shiney and as new again and i remembered why i love this device then this came along i was following the thread on my n900 thinking it cant really get much smoother can it.... ohh how i was wrong.the things i tried to avoid, like reading youtube comments whilst playing the video i can now do, and everything is quicker, im in awe of this machine once again. broadband is gettting connected on wednesday im gonna rock metal gear solid on psx4all and i cant wait,
many thanks all of you


written at 825 mhz

Re: Overclock the N900?
 

Havent tested yet, what I have written is based on watching conky ... but I assume youre right about the battery life ...

Re: Overclock the N900?
 

I have uploaded an untested kernel which is supposed to support 125MHz-1GHz and limits by default to 600MHz. I currently can't test it myself due to lack of my USB cable but I'd glad to get feedback from brave volunteers. more details here:

Re: Overclock the N900?
 

After reading through this thread, I decided to try the 125-900mhz kernel, as I don't recall seeing anybody with problems with 900mhz (yet).

I've had no stability issues at all, most of the transitions and applications are snappier (not they were ever sluggish, but still...). I used to wait for 5 seconds before contacts showed up when I clicked contacts from within the phone application, now it's down to 3 seconds! Linear speed improvement!

The only problem I had so far was that flash support in Firefox became very slow with the 900mhz kernel, and the problem was solved when I uninstalled and re-installed Firefox. Now Flash works almost as good as in MicroB, and I'd say it works PERFECTLY with MicroB.

As the idle speed is now 125mhz as opposed to 250mhz, I believe there would be next to none extra strain to the battery. We'll all see if there will be any negative effects of overclocking the n900 in the mid to long-term but so far it seems the device handles the extra speed just fine...

My thanks go to everybody who contributed to this thread!

Re: Overclock the N900?
 

As it stands, it seems that the clock handling code only supports one frequency per OPP. Instead of fixing it I hacked around this limitation. This patch has a range of nine frequencies, from 125 to 600, but at boot scaling_max_freq is at 600000.

Re: Overclock the N900?
 

Exactly the same here.


It has been asked here before with no answer. Any ideas how will this affect the coming PR1.2? Current fw version is shown to be unknown after the overclocking.
