Re: 125/1000 cpu freqs
 

I got a problem , at 250/1000 freqs when I play a video sometimes it gets stuck and I have to close the media player , so I thought the voltage on 500 mhz freq it's too low and I made limits 250/500 to test these two freqs . While playing several videos I had putty open in background and waiting the video to crash , when it crashed I used "awk '{print $1/1000" MHz"}' /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq" command and I got 550Mhz and it got stuck at this frequency till I open again mediaplayer . What actually makes the frequency jump over the limit ? :-/

What's that IGNORE_NICE_LOAD ? I wanna know if worths enabling it or not . :-s

Re: 125/1000 cpu freqs
 

It does exactly what it says it does - ignore nice load. Basically, if you leave that on 0, all processes count towards the up_threshold. If you set that to 1, renice'd processes don't count towards the up_threshold (can be bad or good depending on which app is misbehaving this time :P )

Leave it on 0.

EDIT: Saw the first post. Increase your voltages, simplify the steps. 125-1000 isn't recommended, try to do 250-1000 probably with steps in 250-500-750-1000, whatever voltage your phone needs, and if possible, SR on.

Now I'm using 0:20,90 250:25,180 500:30,360 1000:60,500 . I don't think SR would work at 1000 , I know it works only with max freq 805 mhz .

Re: 125/1000 cpu freqs
 

VDD2 SR works, try to enable it...
I don't know if it makes much difference, but yeah...

Re: 125/1000 cpu freqs
 

Ok , I enabled VDD2 SR . What actually is this Smart Reflex ? what is doing ?

Sorry for many questions , I am pretty noob and this phone is making me curious everyday , that's why I love it . :D

Re: 125/1000 cpu freqs
 

It turns off parts of the chip not in use + automatically lowers the voltage for parts that don't need too much. I've got VDD1 and VDD2 SR enabled, and I don't overclock.

Re: 125/1000 cpu freqs
 

From my experience, enabling SmartReflex with core freq above 850Mhz instantly reboots the phone; at 805Mhz and below it works flawlessly; and at exactly 850Mhz it works, but I start to get artifacts on the screen and dmesg errors related to the graphics chip. I have a hunch that's because the DSP frequency goes up to 500Mhz at 850+, but is only at 430Mhz for 600-805 (and lower still for core freqs below that). I'm lucky with my N900 though (since it was replaced by Nokia Care) as its CPU is good enough to be stable whilst running the "drained" config, so of course YMMV.

Re: 125/1000 cpu freqs
 

Does the SR needs an increase in voltages ? Because it causes unexpected reboots with same freqs and voltages from other profile without SR .

stable profile : FREQS="0:20,90 125:20,90 250:25,180 500:30,360" , VDD1=0 VDD2=0
sr profile : FREQS="0:20,90 125:20,90 250:25,180 500:30,360" , VDD=1 VDD2=1

Where is the problem ?
