Re: overclocking kernel modules for PR1.2
 
Has anyone noticed any performance boost??
Thats the point of overclocking..
I hope there's soon a comprehensive guide on how to overclock N9..
Keep up the good work..!!!!!

I did not try for > 1.1 Ghz . I will wait for your guide to disable smartreflex first :)

Well we need a benchmark or something, I'm sure there is some web based one we can play with. I'll leave that to you guys as I'm having enough of a headache trying to learn this stuff.

I just did some test with Browsermark and Sunspider Javascript 0.9.1 The overclocking N9 has a better score but the different is minimal

yeah sorry I'm dumb -- you need root to disable smartreflex, 1200 works (for me) if I do it.
I did get a reboot last time I tried to switch back to 1ghz, there could be some problems with my module. I know when it initializes it binds to certain addresses but I don't know if those are valid forever or not.
My best score in sunspider was 3277.9ms @ 1.1ghz.

Coud you please give a how to disable smartreflex ? :)
My score in sunspider is 3218.9ms @ 1.1ghz

With the normal clock the score is 3581ms @1.0Ghz

Minimal different when doing Browsermark :
1.0Ghz :

Yeah I better put it in the first post...
opensh and then echo 0 > /sys/power/sr_vdd1_autocomp

There might be a few tools that we can use from the developer mode devtools. Swap logger in performance looks like a go to me, it doesn't have to be used with the instrumentation dashboard via QtSDK but it gives a nice readout, I'm yet to actually try it out though.

I'm sure we could use something from the power analysis devtools aswell for power consumption to test undervolt etc, I'll read up on those ones later.

Smart reflex definitely caused problems with getting good overclocking results on the N900. e.g. WIth it enabled, it was stable to around 850-900MHz for many but when turned off, it could go to 1.1GHz stable.

Problem is to define "when the phone is stable"...

Could go up to 1.2 without the smart ref command but how could it be possible to know if the phone is stable.. Tried Grand turismo on psx emulator, nothing more...
