Re: overclocking kernel modules for PR1.2 [v1.4]
 

i doubt 1.37ghz is "instant freeze"
it's more like "change frequency too many times" = "instant freeze"
did you try again after rebooting?

Re: overclocking kernel modules for PR1.2 [v1.4]
 

I didn't try from 1.0 direct to 1.37.
I read somewhere that it is more secure do the steps: 1.0 to 1.1 to 1.2 to 1.3

Re: overclocking kernel modules for PR1.2 [v1.4]
 

My phone is running 1350mhz with 1387500 voltage for 5 days with no problem . Even with SR disabled , I feel battery life the same , lol .

Re: overclocking kernel modules for PR1.2 [v1.4]
 

The battery life is really the same???

Re: overclocking kernel modules for PR1.2 [v1.4]
 

I can confirm this on 1,3 GHz. Battery life is the same, haven´t noticed any changes...

Re: overclocking kernel modules for PR1.2 [v1.4]
 

any real boost at 1.3?

Re: overclocking kernel modules for PR1.2 [v1.4]
 

yeah just like jleholeho asked does it feel smoother having 1.3Ghz overclock???

Re: overclocking kernel modules for PR1.2 [v1.4]
 

With up_threshold 75?

Edit: Oh yes, it's 75. I just found it out from your script.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

This idea comes from PC overclocking, but i can tell you from experience, this makes absolutely no difference.

Jumping from 1Ghz to 1.3Ghz is no less secure or stable then going 1 to 1.1 and then to 1.2 and then to 1.3.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Well, it's probably a good idea to increment a little at a time and then do stability testing. This provides a more scientific approach than just ramping it up and hoping it doesn't crash.

However, once you've found the highest stable clock speed, there's no reason not to set it to that speed straight away.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Yeah thats what I meant.

When testing its a good idea to increment and test using a similar method to see the performance differences and test stability.

But once you have a max, or a rough idea of ur max, its safe to just bump straight to it :)

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Reporting 1,3 GHz here, voltage 1375000. The smart reflex is on. First batch phone from Finland. Seems solid so far after two hours of brutal usage, including incoming phone calls under the stress.

1,3GHz, voltages at 1275000 and with SR on recording went fine, but watching the result crashed the phone. The video was ok after the reboot with no visible corruption though.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Working fine so far at 1.3 GHz with 1.3 V (SR on). What's the default voltage at stock clocks?

Re: overclocking kernel modules for PR1.2 [v1.4]
 

I don`t think that ui feels smoother after OC. Maybe some minimal difference. But definitely boosting app launch and web browsing. Recommended!

Re: overclocking kernel modules for PR1.2 [v1.4]
 

WoW just tried directly @ 1.3 Ghz and default voltage.

Perfectly stable !

UI is a little bit smoother IMO, but the biggest difference is time to launch Qneptunea, just amazing the time loading difference and smoothness while scrolling tweets !

Thanks :D

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Is there any *.deb app to install? to avoid the terminal thing of copy and install?

I mean an installer of the overclock thing, that should be installed after the inception

Re: overclocking kernel modules for PR1.2 [v1.4]
 

yeah it's bundled with the whatsapp deb

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Im tired of your intolerance

Advice: Go out and get laid

Re: overclocking kernel modules for PR1.2 [v1.4]
 

I can't because I'm writing a goddamn UI for idiots that can't type two things into a terminal

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Flotron, be happy he is even making this effort, otherwise overclocking on the N9 would take so much longer.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Reporting 1,4GHz with 1,375V, SR on. N9 seems stable after half an hour of testing. Will inform if it crashes.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

I think using GPS would crash the overclock

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Thanks for the idea. Tested it and it is still solid. Happyjoy! :)

Re: overclocking kernel modules for PR1.2 [v1.4]
 

You got a pretty good device , mine is not responding after 1375mhz even with 1.38 voltage and no SR . :)

I wanna ask if there is a chance to go over 1387500 voltage ? If no , this means the limit of N9 is ~1300-1400mhz .

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Tried playing gta3 in nitdroid running at 1.3ghz and its so much smoother then stock. Played for 30min and stable all the way. :)

Re: overclocking kernel modules for PR1.2 [v1.4]
 

I would have said it comes free with Duke Nukem Forever... then I realized DNF actually exists now.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

For me, 1.3 V seems to be the minimum needed for 1.3 GHz, anything lower and apps will start crashing eventually. Also, after going back to default clocks, frankly, it's very hard to perceive any clear difference in general usage, I though apps were opening faster but I'm not so sure anymore without proper testing.

Is it possible to overclock the GPU? :D

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Blin... Facing a issue :

1GHZ > 1.2GHz SR on - OK

1.2GHz SR on> SR off - OK

12GHZ SR off > 1Ghz SR off- OK

1Ghz SR off > 1Ghz SR on- OK

BUT:

1GHZ > 1.2GHz SR on - OK
1.2GHz SR on> SR off,1GHZ,SR on - NOK

If I desactivate sr, change freq and reactivate it in the same script, reboot.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Good bug report but a pretty ridiculous scenario is needed to cause the reboot :P

Re: overclocking kernel modules for PR1.2 [v1.4]
 

People overclocking other phones using OMAP3630 usually talk about voltage in terms of VSEL, which seems to translate to actual voltage according to V = VSEL * 0.0125 V + 0.6 V, according to OMAP3630 technical reference manual . So 1.375 V would translate to VSEL 62. Looks like Droid X users, for example, are able to set much higher VSELs than this so it might be that the maximum allowed voltage in the Harmattan kernel is rather conservative (and relatively safe?).

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Haha, indeed... I gave up and stay at 1.3 with max clock at 95% load.. Let see the battery impact..

Re: overclocking kernel modules for PR1.2 [v1.4]
 

From what I understand, 1.2ghz is the safest to overclock to not melt your cpu after an extended period.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Hello folks, I did some "scientific" research with my OC`d N9. I took stopwatch and measured how the app launch time changed after overclock compared to stock.

I took three different times on every app on both clockspeeds and take the average of them. Phone was connected to wifi during test.

Based on this very non-scientific experiment I would say that +300mhz gives about 15-20% performance boost what comes to app launch. Of course there are many variables in this test but I think that it give a very good clue about the truth.

Tell me about your experienses. Maybe I need to do something similar with browsing speed also...

Re: overclocking kernel modules for PR1.2 [v1.4]
 

You are correct, I simply bumped my speed to 1.2Ghz without even touching voltage or smart reflex and ive been stable for the past week, with using the Sat Nav and bluetooth and lots of texting, video viewing ect.

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Very good tests..
As far as browser testing, you could try some heavy loading sites(cnet,engadget) with stock browser and firefox as well..
Looking forward to your next tests..!!!

Re: overclocking kernel modules for PR1.2 [v1.4]
 

If you used the modules of Creamy Goodness directly the voltage will be automatically bumped up to the maximum (1.375 V) when clocking higher than 1.1 GHz, unless overridden. You can check the voltage by doing cat /proc/opptimizer.

Anyone tested how far you can actually go with stock volts (for me that is 1.1875 V)?

Re: overclocking kernel modules for PR1.2 [v1.4]
 

I think i got to 1150 or so

Re: overclocking kernel modules for PR1.2 [v1.4]
 

Creamy Goodness can we somehow make sure that the voltage used is not overdone? As in can we use the minimal amount needed over stock to get to 1.2ghz?

Also thank you so much for your efforts on this project so far.
