Re: Overclock the N900?
 

please Letho don't go crazy, coz its the nature: the more you get the more you want, dont wanna lose you so early ;) BTW, can you plz try enna and let me/us know how it performs. thanks

Re: Overclock the N900?
 

Great going!! What about the temperature ?

Re: Overclock the N900?
 

good work mate

i want to run the 800mhz overclock if you can pm me that would be great and much appreciated mate

brilliant thankyou :-)

edit
pm sent to you :-)

Re: Overclock the N900?
 

Hot stuff! It seems that you have to take the device to Sampsa Kurri (muropaketti.com) and do some serious overclocking tests with liquid nitrogen. :D

But seriously, this might be interesting news for overclocking sites, and also more publicity for N900.

Re: Overclock the N900?
 

Good stuff, if everything goes well i will clock mine at 800mhz

Re: Overclock the N900?
 

iam hoping he will send me the files needed so i can test at this speed mate ill keep you updated the droid runs perfectly well at 800mhz so iam thinking the n900 should be ok

infact some users have taken the droid to 1ghz :-)

good to see you about mate i remember you from i8910 users and aas :-)

Re: Overclock the N900?
 

Now we need some benchmarks to see the performance increase

Re: Overclock the N900?
 

^ Maybe video :)

I certainly would like to "bump up" my cpu to 800MHz :D

Re: Overclock the N900?
 

Pi calculates approximately 31% faster at 800 MHz compared to 600, which is very close to what one would expect :)

So far my device has been stable at 800 MHz, and the boost given for any CPU-bound task is very nice. After getting used to this it would probably suck to go back to 600 :)

One has to remember though that even if the device runs stable, it's lifetime could get seriously reduced due to increased thermal stress. So those users who were worrying about their N900s getting obsolete probably don't need to apply... :rolleyes:

Re: Overclock the N900?
 

So is there any easy way to speed up to 800MHz looking from user who knows linux, but isn't that familiar by itself? :)

Re: Overclock the N900?
 

I didnt increase voltage. So far I've tested a lot of different applications that require heavy cpu calculating power and in short 10-15min bursts I've yet to notice any misbehaviour @ 950mhz. The phone is now so smooth acting, but for how long?

I dont encourage anyone to run at faster than stock clockspeeds. Actually I should say (just to cover my back) that one should never run it past 600mhz.





I'll upload the kernel files for 650,700,750,800,825,850,900 somewhere once I've determined my phone wont fry. I dont consider it nice behaviour to upload hazardous files on the internet.

Re: Overclock the N900?
 

That would be nice. I certainly would try those up to 800MHz. Not sure is it wise, but hey... who frakking cares! :D

Re: Overclock the N900?
 

I'll try 650 or 700mhz to be safe.I want to know about the kinetic scrolling,is more smooth now?

Re: Overclock the N900?
 

In one word. Yes.

pm sent back lehto mate thanks

Re: Overclock the N900?
 

this should be linked on engadget, see how much they dumb it down.topworkthough,welldon!

Re: Overclock the N900?
 

subscribed.

Re: Overclock the N900?
 

I'm actually more interested in what happens if you drop the maximum to 500 or 550 (and ideally reduce the voltage if possible). I get about 50% more battery life out of my laptop with a PentiumM processor using NHC to reduce its max to 1.4 GHz from 1.6 and reducing the voltage for all clock steps, and the difference in performance is negligible.

Re: Overclock the N900?
 

Thanks alot Lehto for the files. Yes i know how the flasher works..

Re: Overclock the N900?
 

Another thing that might be worth trying is to run 600MHz at OPP3 instead of OPP5. It might be out of spec, but Pandora people report that it is stable and it might save some battery if your processor spends a lot of time at this frequency.

Re: Overclock the N900?
 

Lehto you are the legend right now, BUT we need the files:)

I really want to try the 800mhz clock. And if it makes a little performance then you will get donation from me for sure.

Re: Overclock the N900?
 

Yes, that's what i was looking for. Would really be interested in seeing the effects of that kind of change.

Re: Overclock the N900?
 

Thanks for the files..Lehto

EDIT:
* on device flashing... :

- open terminal,
type ....
"sudo gainroot" [enter]
"softupd -vv -s --local" [enter]

- open new terminal......
type....
"sudo gainroot" [enter]
"flasher --local -f -k <path-for-kernel_zimage_file>" [enter]

when complete, type...
"sync" [enter]
"reboot" [enter]

Re: Overclock the N900?
 

thanks for files????


You got the files from pm???


plz share them with us.....

Re: Overclock the N900?
 

If somebody is "smart" enough to flash a kernel, I believe they should understand the breakability of their actions. I don't see why files can't be posted - compiled kernel and modified headers and conf files, included.

7 slot would be nice, 125MHz to 800MHz.

I plan on patching and merging with: http://forums.internettablettalk.com...713#post568713

Re: Overclock the N900?
 

when i try to flash my kernel i use the command

$ flasher-3.5 -k <kernelimage> -f -R

in maemo flasher to try this out it says access denied

i have the files that i need placed in maemo flasher folder on pc

anyone got any idears please

Re: Overclock the N900?
 

I still do not get people's concern's (aside from the battery issue). The Droid is rock solid at 800mhz and was also fine at 1ghz (both set with min scale of 250mhz). 600mhz is nowhere near the ceiling of the 3430, but 1.2ghz does seem to be pushing it (temps increase 10 degrees and some freeze ups). Seems the sweet spot for the 3430 is a max of about 800 to 900 mhz.

Then again, the Droid on 3G lasts longer when clocked to 800mhz than the N900 does when in 2G and 600mhz. Yes, apples to oranges, but still seems like the N900 is not as efficient as it should be (pulse audio factor?).

Re: Overclock the N900?
 

sudo flasher-3.5 -k <kernelimage> -f -R

Re: Overclock the N900?
 

Good point.

It would be cool to have profiles: Browsing and media lower clock and for games (such as MAME and PSX4ALL) a profile to 800mhz.

There are very stable low volt kernels for Droid that clock up to 1.2ghz and have dynamic profiles in an app called SetCPU. Most testing suggests the best range for the 3430 is scaling up to 800 to 900 mhz. When you go past 1ghz, temps begin climbing and freezes start.

Re: Overclock the N900?
 

Posting from the n900 - overspeeding at 900mhz.

Boy, does this beast fly or what?

Could never never go back to 600mhz. Might as well prepare for the worst.

let's see if it survives till the next firmware update.

Re: Overclock the N900?
 

Depending on the actual ceiling of the chipset, the actual degradation curve of the silicon is not proportional, so if you stay under the point / ceiling, the chipset should last a normal life. Based on most Droid efforts, the "comfort" zone appears to be 800 mhz, but most report no problems at 900mhz or 1ghz. All kinds of issues are reported at 1.2ghz and this is the point temps spike by ten degrees.

Depending on the cooling system in the N900 compared to the Droid, the N900 should last as long at 800mhz as 600mhz (for a max speed with dynamic clocking). Seems the N900 has better heat dissipation (based on tear-down views of both).

The point that the actual ceiling is breached, the temps will spike about ten degress and freezing will occur. This is the point and state that the chipset will have a much shorter life span. Unless for whatever reason, the 3430 in the Droid is a more robust / better version.

Re: Overclock the N900?
 

It's awesome how scalable OMAP3's can be :)

Just imagine how fast a device with an OMAP4 running @ 2Ghz default would be if it was overclocked? :D

Re: Overclock the N900?
 

I'm actually quite surprised how good the overclocking potential turned out to be. I had never imagined that the thing would boot up even close to 1 GHz.

Re: Overclock the N900?
 

Me neither, its actually 100% stable at 1000mhz. Im running DSP @ 520mhz and its not giving me any trouble either. Playing videos is now stupidly smooth and the onscreen gui in kmplayer doesnt slow down at all.

Re: Overclock the N900?
 

woow, why not trying a 720p video in mkv format with mplayer ??? lol

Re: Overclock the N900?
 

This all sounds fab, just waiting for the files now and a quick guide on howto do it, is it the same procedure as flashing a new firmware with flasher 3.5?

Re: Overclock the N900?
 

Pretty much yes. In linux environment its like:
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

Re: Overclock the N900?
 

biggzy, look here http://wiki.maemo.org/Documentation/...o_Kernel_Guide

Re: Overclock the N900?
 

lehto your a diamond mate this is brilliant thankyou so so much

:-)

on windows biggzy just run maemo flasher as admin then run the command

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

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

Re: Overclock the N900?
 

hu ? why not ??
