Re: Overclock the N900?
 

As the SmartReflex currently is not enabled by default (MB7633) I highly doubt that this is the case ...

Re: Overclock the N900?
 

I have the 900 Mhz Kernel
I used: apt-get install --reinstall mp-fremantle-003-pr , then reboot, and the information is back again :)

And i still have the 900 Mhz runing.
So.. no side effects?

Can anyone explain what it does, since i thing the 900 Mhz kernel is not affected and the device info is back.

Thanks you all :)

Re: Overclock the N900?
 

If these are real numbers - indeed 20K does seems enough time :D But I think, even in this case, the lifetime of the CPU could be prolonged if we find a way to read the actual CPU temp sensor and limit the max freq above certain temperature values through

Re: Overclock the N900?
 

This might sound nooby, and somewhat stupid... But surely if you're overclocking you are just changing the limit the chip can run at? Meaning that just because it is overclocked to X it doesn't mean it will be running at that speed all the time? Only when high cpu usage programs are run? I would very much like to speed my N900 up a little becuase I watch alot of films but the films run just below perfect, like 0.01 fps 2 slow and its noticeable, but I am a noob and have no idea how to use a flasher or use a kernel flasher file lol, from what I've read it seems this isn't doing so bad with the tests. Pretty cool that it can be overclocked lol, well done to everyone who has done it, you're the people that make the world go round.

Edit, I was on page 28.. There are over 120! Lol. Amazing.

this is prob the easiest way, i tried it this more to go from 900 to 825mhz

Re: Overclock the N900?
 

What about previous steps, like getting a flasher, or similar?

For noobs that is, like myself lol.

Thanks,

Re: Overclock the N900?
 

I used the on device fiasco method to clock it up to 900mhz, it took seconds to do and it also retained the 'about' info. Foolproof method, and running nicely so far.

Re: Overclock the N900?
 

Then use the AC Adapter instead of plugging it in your computer...

Re: Overclock the N900?
 

"SmartReflex on" could be maybe the reason for unexpected reboot... At least many person has such issue even with stock kernel.

Question to the Overclocker's community:

what is your experience with any OC kernel + "smartreflex enabled"?
is it working fine somewhere?

Re: Overclock the N900?
 

Is it possible to update to PR1.2 after overclock? OTA? How can you go back to the standard settings??? Just use the 600mhz file???

Re: Overclock the N900?
 

I forgot to mention, I noticed mine warm up surfing on 3G. That said, I haven't played anything other than Bounce that is GPU heavy. Overall though, I still think most times when the N900 feels hot its the battery warming up due to heavy drain.

That's funny as the 900Mhz kernel is infinitely faster than 600Mhz, things are instant that were seconds before. Not games, everything. I noticed immediately that bootup was super fast, everything is more responsive.

Re: Overclock the N900?
 

One good test to those who want to see visible OC changes, is to install ENNA (like a media center for those who dont know..i think lol).

Booting speed; Gallery Scrooling..Wow, what a difference between the 600 Mhz and 900 Mhz.

Still thinking to test the 900 Mhz with 500 DSP..but there are no much comments about it..i'm afraiiddddddd ahahahaha : )

Regards,

Re: Overclock the N900?
 

That's what I want to know..once the PR 1.2 update is up..will it revert back to 600 mhz?

A pie you mean? :D

Re: Overclock the N900?
 

I use the 900Mhz kernel, and when I try to activate smartreflex (after boot, not from the config file) -> instant reboot

Re: Overclock the N900?
 

I'm fairly sure it will revert back to "normal" non-overclocked state after the PR1.2 update. I've noted about this in my guide I believe. Check my sig.

And yes, OTA will work just fine. But I do recommend for everyone to perform major firmware updates without the N900 overclocked. This should just be common sense to anyone who performs the overclock.

Re: Overclock the N900?
 

What's the opinion on using the overclock firmware just to lower resting from 250mhz to 125mhz and not actually up it over 600?

will this give me much of a battery boost?

bit thanks out to jakiman and his summary post

Re: Overclock the N900?
 

It's hard to say if it'll have much noticeable impact. Well, doubt it'll make it any worse though. :D

Re: Overclock the N900?
 

I flashed the 900MHz with stock DSP kernel to my N900 about 36 hours ago, and had no problems whatsoever in terms of stability.

A few hours ago, I tuned the CPU down a little to 800MHz, just to be on the safe side as it tends to get very hot in summer around here.

You can never tell for sure, but I doubt I'll ever have any problems with the 125-800MHz settings.

On a side note, 900MHz is noticeably snappier than 800MHz, but I think I can live with the difference :))

Re: Overclock the N900?
 

Thanks a lot , I wanted to know if I go back to stock kernel , can I update the phone over the air and the "about" in setting is going to show the firmware version ?

Cheers

Re: Overclock the N900?
 

Im running 900mhz with the 500DSP, have been for about 48 hours now and did it using the onboard flasher, not had a single reboot, phone is much faster, battery life is better, not getting any warmer then normal, youtube videos run smooth and I still have my info in the about product page.

So far.. very happy!

Re: Overclock the N900?
 

i have flashed 800Mhz one from device and info still there :)

Re: Overclock the N900?
 

@hycraig

try:

dpkg -l |grep mp-fremantle

And look for similarities. Just reinstall the one which seams to be "right". "dpkg -l" only shows installed package - so you can't damage something.

Re: Overclock the N900?
 

Personally I would recommend to do major updates by a complete reflash, it leaves less junk lying around. Its the same as desktop Linux or even Windows. An upgrade works, but a complete reinstall with an already updated version works better.

I updated to PR1.1 OTA and then later flashed the global PR1.1 so I could get PR1.1.1 in the UK. My N900 was far faster after a complete reflash rather than an upgrade and I got a clean slate to install less extras-devel packages on, as I knew then which were useful and which weren't.

As for overclocking, presumably after PR1.2 comes out there will be a new kernel source out also that you will be able to patch the same as now. So everyone will be able to flash back to 900Mhz within minutes of PR1.2 release, assuming the kernel source is released at the same time. In reality I would expect the kernel source to show up BEFORE the firmware, as they have to compile it from somewhere after all. ;)

Re: Overclock the N900?
 

Hi all,

Just a reminder that overclocking is one of the ways that you actually do void any sort of warranty on the device.

There is a reason for designing the device to run at 600MHz, and that is to keep it stable and safe.

In the Maemo Summit there was a lightning talk by Igor Stoppa on power management, and the only line I remember from it is: "Please don't overclock the CPU."

Re: Overclock the N900?
 

can you tell me exactly what you typed in xterm please.

Re: Overclock the N900?
 

Haha...I overclocked to 800 mhz 5 mins ago but you've convinced me to go back to stock for now...I think I'll wait for a few weeks to see if anyone has had any problems..
Sorry for not wanting to be the guinea pig..i really like this phone :)

Re: Overclock the N900?
 

I'm running the 825 kernel with smart reflex enabled and it's working fine. With the 850/450 one it crashed the first time I played a flash video through the browser. Disabled smart reflex made the 850 work ok. 900 wasn't even booting with smart reflex enabled (usually crashed just after the NOKIA logo), but I haven't tried with smart reflex disabled.
In conclusion, 825 with the battery life benefits of smart reflex was a good choice for me.

Re: Overclock the N900?
 

I have just gone back to the 600mhz stock one too bit paranoid about it too.

Re: Overclock the N900?
 

It is not that I want to spoil anybodies fun, but the audience in these forums is not composed of only people with 10+ years of Linux experience, and fond memories of i486 overclocking.

So when anyone posts guidance like in this thread, please consider twice what you are doing.

Re: Overclock the N900?
 

Now two days with @900Mhz and no problems what so ever. Even tried with @1000Mhz and that was also working but I didn't notice any performance difference compared to @900Mhz so I reverted back to that.

Re: Overclock the N900?
 

I got my N900 OC'ed to 900Mhz, stock DSP. Enabled SmartReflex through /etc/pmconfig then rebooted, twice. No problems so far (48 hours). Didn't decrease max frequency to 825Mhz, either, which is good.

Edit: That's weird. I just rebooted again, and now I get stuck at the Nokia logo. I guess SmartReflex doesn't really like 900Mhz. Heh.

Also, take note: I'm actually waiting for this device to fry (although I hope it won't), since I'm in a tropical country where it can easily hit >35C midday, at least recently. I basically ignored Lehto's warning about not going beyond 800Mhz on warmer climate. :P

Re: Overclock the N900?
 

How's the batterylife?

Re: Overclock the N900?
 

Not necessarily. It primarily depends on your usage pattern, going ping-pong between 125 and 500 in certain cases can be worse than a steady 250 (the same goes for performance lag).

Re: Overclock the N900?
 

Hard to say since I've used the phone like a madman after overclocking it :D
Yesterday it last 14 hours under heavy usage and that's no different than it was before.

Re: Overclock the N900?
 

Your firmware version is not "generic"

In my case, I has to use "mp-fremantle-003-pr"

You will find out by typing the following.....

dpkg -l | grep mp-fremantle

Re: Overclock the N900?
 

this wont work on the most basic windows 7 64 bit tho will it?

Re: Overclock the N900?
 

Using 900mhz-stock DSP and recording a few video clips... So far no difference,
frames still dropping and occasional stutter.

Not sure why I thought it would improve that particular area in performance terms.
