Can the N900 be pushed past 1150MHz?
 

Well can it? Can the ARM Cortex A-8 be pushed pasted 1150MHz?

(Not that I want to do it, well I kind of do, but I am more curious if it is possible.)

Re: Can the N900 be pushed past 1150MHz?
 

Why don't you try it and then let us know?
A question that only you could answer :)

Re: Can the N900 be pushed past 1150MHz?
 

Well I believe Titans Kernel maxes out at 1150Mhz.

Edit the frequency config file and power setting will gives you more OC :) do it at your own risk.

Re: Can the N900 be pushed past 1150MHz?
 

Yes. It can run faster. It's just a bunch of transitors after all. You just have to be lucky to have a good sample in your N900. Lehto has managed to boot at 1220Mhz on his N900 on a really cold day. But it was unstable. Not sure if he tried pushing more voltage into it. But we still have many unknown variables so it's difficult to know why it's becoming unstable. (affect on heat, DSP, GPU etc)

Are you sure? AFAIK, both Titan and Lehto has locked their kernel to max of 1150Mhz.

Then again, remember the guy who went to 1.7ghz stable due to a heat sink?

Re: Can the N900 be pushed past 1150MHz?
 

That was fake.Go look at the wiki.

Re: Can the N900 be pushed past 1150MHz?
 

mine is unstable @1100mhz.......reboot, reboot, reboot and "an unexpected reboot has occurred, your kernel settings where not loaded!"

Why stop there when the same CPU can be overclocked to 3Ghz? http://v7.tinypic.com/player.swf?file=xe3d4i&s=7

(j/k, relax)

Re: Can the N900 be pushed past 1150MHz?
 

I think the 1.15ghz limit is hard-coded in Titan's kernel. In order to get around that, you've got to compile your own kernel with that limkit removed.

As far as actually making it run above that speed.. Possible, depending on sample, temperature and voltage.

I got mine stable with 1150mhz @ starving while playing psx4m for 2 hours... Would that mean I can still push it more? Just asking if it's capable but not planning to overclock my n900. Just tested it's limits :D

Re: Can the N900 be pushed past 1150MHz?
 

People have gotten the Motorola Droid, which uses the same SoC as the N900 to 1300mhz.

It can go higher than 1150mhz, the limit is only in place for user's safety.

Re: Can the N900 be pushed past 1150MHz?
 

Personally I have been running @ 1150MHz for a WHILE and I have NEVER experienced any kind of error and my battery life is just fine.

I started out at 850MHz for a month and then figured why not try 1000MHz then after all was well with 1000MHz for a day I set it at 500MHz-1150MHz and all is perfect.

Re: Can the N900 be pushed past 1150MHz?
 

Perhaps I should use my little pocket hydrogene cooler together with my n900.:cool:

Re: Can the N900 be pushed past 1150MHz?
 

My N900 already becomes a little bit instable at 900Mhz (the one program that appears to be indicating instability best is MicroB for some reason). I haven't tried increasing the voltage though...it's a tradeoff between battery and performance. But I would guess there's a clear difference between older and newer devices in production. Mine is older (Nov. 2009) and is not as 'overclockable' like I would guess newer ones are.

Re: Can the N900 be pushed past 1150MHz?
 

nothing for me.
can't go past 900mhz :(

Re: Can the N900 be pushed past 1150MHz?
 

What do you mean by "unstable"? I bought mine the first week it was out.

Re: Can the N900 be pushed past 1150MHz?
 

to make this clear to every dumb person not using his brain..
unstable isnt related to the frequency but is relevant to volting
if undervolted, the frequency wont get enough power to work effeciently resulting in restarts, jams, and closing of applications..

the MOST stable volting is the nokia's default settings..

Re: Can the N900 be pushed past 1150MHz?
 

AFAIK its the newer ones that have more trouble clocking to higher freqs, i got mine in january and its stable all the way to 1150Mhz on ideal, i've heard from alot of people with newer devices that they cant get past 800-850Mhz although all chips are different and im sure some of the newer ones can get all the way up to 1150Mhz.

Re: Can the N900 be pushed past 1150MHz?
 

Yes, briefly[1]. Once the magic smoke has escaped you can never put it back in.

[1] unless you are prepared to use specialised cooling solutions that make the device decidedly non-portable, in which case just get a beagle^Wpandaboard.

Re: Can the N900 be pushed past 1150MHz?
 

Sure, try it.....:)....but don`t rush back crying.

Re: Can the N900 be pushed past 1150MHz?
 

@xxxxts: It might be unrelated, but before I overclocked/undervolted with Powerkernel I never had any sudden crashes in MicroB (meaning it closes itself with internal error). It even happens that the device resets itself during browsing. I can strangely enough run pretty demanding games without resets, and that speaks against the clocking.
What I did was trying the different presetschemes and the only one I got working at 250-900 Mhz was the lv scheme. The other caused pretty soon a device reset.
I haven't let's say created a device specific scheme yet by tuning and tweaking and that's maybe what I have to do before saying anything at all. But I would have expected that at least a few of those default schemes would work better than the did.
That's why I went to the conclusion that my device wasn't very "overclockable".

Any clues here?

EDIT: BTW, anything above 900 Mhz on the lv scheme pretty soon resets the device. This is after all a matter of factory yield and depends on the success in the manufacturing process. Some chips are very tolerant whereas some doesn't go much past the "default".

Re: Can the N900 be pushed past 1150MHz?
 

yeah for me the same too but it has nothing to do with the frequency,its the voltage.
on the lv profile i can't go past 900 mhz but at the default voltage my phone is running at 950 since a few hours and so far no probs (tested videos,emus,flash and browser)

Re: Can the N900 be pushed past 1150MHz?
 

mine running@1150mhz and no problems at all.Happy
