Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
Mines running @ 1150 both Maemo and Nitdroid. It's does get a bit warmer then 600. Only a bit. The response time is amazing.
I read the Arm cortex A8 spec and it said is scalable from 600MHz to greater than 1GHz. I don't see a problem in overclocking.

Temp has never been over 35 degrees. This is when charging and streaming youtube!

The issue is the battery life. Nokia should have given a high capacity battery instead of a crap battery.

Overall i think overclocking is worth it. I'm fine with charging it every night.

This summer I forgot my overclocked N900 in my car when the sun was "burning" it. When i came back, my phone was so hot that i couldnt touch it,really!
This unbrickable device is still alive since a year :)

wait: the n900 is not open source. it is closed down source and that is not only the software but also the specifications of the chipset. all in the secret. some smart guys found specs of chips that may be clones of the used ones and we have specs of similar chips but nothing official about the real used chipset let alone anything telling how the device was designed to utilize the chips(a rough idea:yes. but not the necessary details ). nokia doesn't reveal it's secrets atleast didn't up to now.

Of course by overclocking the CPU, the device performs faster in general but there are many variables that cannot be calculated by the users or individual developers in this forum i.e. the lifespan of the cpu, overheating on the small device vis a vis a desktop cpu and other things.

Since overclocking seems to be so popular among the users here, why is it that the updated firmware not address it a little bit? Is it possible that there are somehow some minor repercussions? It might not be very severe but there could be reasons why it is set at stock value to run at 250 - 600 Mhz.

After reading a couple of forums here and there, I can see that one of the major reasons why the manufacturer would seriously underclock the device is due to battery life i.e. Iphone clocked at about 533Mhz thus Apple seems to boast LOOOONG battery life... Maybe the Nokia manufacturers think that the general public would prefer using their devices for a certain period of time and therefore decided to stock clock it at that value which allows the phone to be run at a certain length of time? No?

If not, if the device can in fact, run MUCH smoother, at NO costs whatsoever to the device, then why won't they set it at THAT value? I'm sure they have tested it to a certain degree during R&D to find out the best CPU speed to run perfectly for a lengthy period.

Besides, I would like to think that if they feel that this open-sourced device can run BETTER without much hassle (as what we all can see, individuals at home able to modify their CPU speeds), why not put it in the next firmware update? Unless there is somewhat a MARKETING PROPAGANDA and refusing to back down in what they have set it originally...

I think if Nokia realises that it could run better at a different CPU speed, they could easily do that in the next update.

In the meantime, I run my pr1.3 stock speed just fine without much complaints.

What do you guys think?

I gree about the profit of companies and their image and all....
Most things are purely about moola, money, yes Mammon is very much alive and well today.

To overclock is to risk. Everyone makes a descision before the go do any overclocking. Descisions needs evaluation. If you want to overclock, go for it.
If you are like me, to wait for something and the use it for what it is designed, then it WILL work the way it should and for longer than expected. That way you end up so appreciative that when, like me, say goodbye to my N6210 I had for 4 years and finally get the N900, am charged up enough to know that stuff can work for us and not the other way around.

Maybe if I have reason to overclock, I would consider for sure.....and make extra sure I save up faster for the E7.

Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
Oh yeah, and about the propaganda thingy - The N900 was never released here in South Africa. It "failed rigour testing 4 times", as quopted by one of the service providers here.
And how is it that a device is so expensive. I mean, it's only hardware, breakable and tiny? Like most of everyone says, its about money and money is power and everyone will not move a muscle it see it be the other way around - the way it's supposed to be already.

How sad it is indeed to have seen the E7 and only will get to have it as a non-grey product in SA only middle 2011....possibly not even get released like the N900 - too advanced and will have everyone bugging the service providers for device support.......like, we are stupid.
I guess most people are - paying through their ears for a piece of hardware....it still isn't right capitalising on it...

good pointing that out... and I think it IS true. No manufacturer in their right mind would open up their entire device for scrutiny and let out all their software and engineering secrets just because of consumer demands. It's true - you hit that at the dot... still, isn't this tablet more open (in whatever way) than others? I think it's quite a bold step anyway right? Unlike like the E7 which probably would ONLY support the latest symbian^3.

Well, this then further enhances my idea that there are still things kept under the rug which we don't know about either the software or chipset/cpu etc... therefore it's quite difficult to make an EXACT quantification about repercussions towards the CPU which to me, is quite a big deal..

... but like what a lot of you said, it's really about preference... some people don't even want to keep it for long anyway.. hehehe.. they'd probably switch to the n9 or e7 or n8 in a moments instance cause they never stick to one gadget longer than 1 year right?

... in the end, whatever that makes you happy.

Dude.. I feel you man, interesting though... did they mention EXACTLY what were the rigor tests? I mean, since it even affected the launching of the device in your place, then it should be quite important tests right? I would certainly imagine that it didn't even pass the most basic of tests if it were to affect the launch of the product in a place...

About the e7, I think it's really sad if they don't launch that with the excuse that you said.. being TOO advanced. I think that would be really bull cause they're SUPPOSED to introduce and SUPPORT the end-users with their products... and people WILL pay through their teeth if they see good support from the manufacturers in providing them good post-purchase services... at least, I would.

I think it's unfair to say like 'people are paying for hardware' cause they're really not JUST paying for hardware eh? If you were to count the weight of the metals, silicones and all that material, I'm sure it'll not amount to much but it's the design and the 'art' of making the hardware and software that packs the pounds. I think it's fair to say that even though some things might shrink in size, you pay more for it because it IS the latest tech in both design and functionality.

tele & andithebest: GREAT!!! WOW!!! I think it really does show the hardy built of the n900 eh! I really hope your devices work fine even after such harsh conditions (not tele..)..

I think in terms of build quality, I have always preferred Nokia to other manufacturers... their hardware and build of their tablets and phones really last... :)

It is, mostly. But with MeeGo on the horizon it's somewhat moot.

Well, don't go claiming it's closed source when it's not. First, which chip are you referring to? And there are chips for which Nokia can't release specs to. You won't get them from anyone else, either.

What do you guys think?
You are actually overclocking the CPU lightly, that is if you go above 800mhz. The 65nm A8 is meant to run at 800mhz stable, and TI produces different SoC variants, 600mhz, 720mhz, 800mhz. Companies have to somehow advertise diverse and new offerings. There is surely a higher fee in getting the 800mhz chip, even though it's just factory overclocked at same voltage.

IMHO, there should be no issues running at 1ghz and above with proper voltage. Snapdragon 1st gen SoC are 65nm and run at 1ghz with slightly lower than starving voltage and are still overclock happy. Lifetime may not shorten, since you are not running 100% max frequency constantly, the CPU does the task given faster and idles sooner.

Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
im using QCPUFreq but it only allows you to change the max freq, so when you choose 1000Mhz its 250 - 1000 with decent not mora than 32 temp.

Dark_Angel85 2010-12-03 11:09
Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
Well, so far, I just had to try it myself to see what the hype was all about..

clocked at 250 900 for a number of days now.. I would say... slight increase in response and loading speed... probably less lag in games and running multiple apps... I regularly don't open too many anyway... tried opening like 20++ apps on purpose and it did slow down a little bit in response time between switching like how it was at 600Mhz.. but maybe just slightly less..

but battery life has indeed been slightly better which is really funny... I don't think I've used it any less than I have when it was at 600Mhz but it is a little bit hotter when charging.. checking the temp every now and then still indicates CPU heat at about 35-38 C

So... I guess... erm... short term effects...

... slightly better speed
... slightly better response
... slightly better battery life
... slightly hotter charging temp

So... probably it's alright now... but if I find anything worrisome, I'll just revert it back.

Don't think I'll go to 1Ghz cause I did that for a short while and the difference in speed was not noticeable compared to the 900Mhz...

Use transition control and reduce the time transitions take (all mine are at 5 except rotation% which is at 15) and install swappolube and use the proposed settings, this will make your phone fly.

Dark_Angel85 2010-12-03 11:13
Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
... just adding to the previous post..

sometimes, after being idle for a little while, the CPU temp does indicate as low as 24-28 C... so this shows that the CPU isn't really being too stressed out idly... well, the minimum is at 250... I did try putting it to 500Mhz minimum but noticed quite a drop in battery life which prompted me to try out the 250Mhz... but I did read somewhere that at some frequencies, it's better at 500Mhz...

... and voltage is set to lv

there hasn't been much input about this app and so far, some have said that the default transitions are better...

haven't tried swappolube... is that a stable programme? Searching as I'm replying this

What? There's been loads. And in what way are the slow transitions better?
It still uses the default transitions, just sped up.

Sorry for not knowing this cause I use the QCPUfreq and cpufrequi which both states cpu temp... so I automatically assume so...

about swappolube, do i just click on proposed settings and don't temper with anything else? could you give me a short walkthrough EXACTLY how to make my n900 fly? thanks man

James_Littler 2010-12-03 11:21
Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
Click proposed, click apply. Simple. Don't mess with the proposed settings until you know exactly what they do.

Dark_Angel85 2010-12-03 11:23
Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
thanks man... really appreciate it

So, do i install the Swappolube or the Swappolube noGUI?

downloading transition control

James_Littler 2010-12-03 11:26
Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
just swappolube, swappolube noGUI has no GUI (graphical user interface), it is just a CLI (command line interface).

James_Littler 2010-12-03 11:28
Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
In transition control, set everything to 5, except rotate % to 15 and Blank max to 10.
Click apply, then click restart desktop (at the bottom).

You will be pleasantly surprised.

dude..... DUDE~~~

That's what I'm talking about man... now that is speed....

Man... I wonder if all that overclocking and all the stuff wasn't necessary... all you gotta do is just do these 2 things and voila...

whoosh....

thanks man

Nope, I've been at 1150 xlv with swappolube and transition control for over 6 months now, no ill side effects what so ever.

Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
marvelous... thanks again.

I read again titan's voltage profile and after 900Mhz, all the voltages (lv, ulv, xlv) have similar voltages (or am I reading it wrongly?) It's at his kernel website http://wiki.maemo.org/Overclocking#I...mental_kernels

Only the starving voltage profile is really under-volted. Have you tried that? your takes?

Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
Speaking of this, I came across SmartReflex which is both on the QCPUfreq and CPUfrequi but everytime I click on it, the device instantly reboots, probably because I have to modify it in the terminal?

You know anything about the SR? Have you tried it?

Why not investigate the governors and post your results in the relevant thread.

VDD2 isn't implemented so will not work, this might be the cause of the crash.
VDD1 will vary the voltage to the mpu (cpu/gpu) around the normal operating voltage.

They are off as default as they appear to be unstable.

SR does not seem to work above 800mhz, I don't know the details, but it's unstable >800mhz.

Try lower speed.

Re: Review on OVERCLOCKED n900 AND RISKS of oc
 
The main negative impact that I have noticed is that when I overclock my N900, my video recording drop frames. With the stock kernel, the recording is smoother. I recorded test videos on a fresh flash of PR1.3 and then a fresh OC flash and the difference is noticeable. I notice the same with PR1.2.

I just can't let go of my need for speed in Mario 64 so I will have to deal with stuttery video recording....

its been oc'd since last year...early...almost 12months now...started at 900mhz and it has been 1.15ghz all the time until just recently when the new community ssu start commingout....as you dont need it to be oc'd anymore...its so damn fast.





....but i do it anyway! :D

That has been discussed ad-nausiem. The general consensus is that underclocking offers no benefit what-so-ever and will actually decrease battery life and performance.
