you can overclock as much as you want
but if you want to overclock more than 900mhz then disable vdd1 before ! (with KPV49)

mv /opt/dbus-scripts/cpu_sleep_speedpatch /opt/dbus-scripts/cpu_sleep 
fi
but no /etc/speedpatch exists. The speedpatch, if I'm correct, is installed in /etc/event.d/speedpatch. This means the cpu_sleep_speedpatch is not installed even if speedpatch is indeed installed.

Can you confirm this?
Thanks a lot for your great work

oh ***** haven't noticed that
i will fix that right away
thank you for warning me

it's job is to renice tasks (if speedpatch installed then /dev/cgroup)
if not (then from /sysparts)

although it's not very important and effective as other configs

Thanks for this awesome improvements. I tried only speedpatch because I don't want that things about auto underclocking in batterypatch. After install and twice reboot there was significant difference in speed(it was much faster of course) especially when switching windows in microB. However, after some days I got in x-terminal those errors desribed in post #2749. My n900 slowed down, too. Then I tried just reinstalling speedpatch and rebooting the device once and problem vanished from x-terminal, it also sped up again.

@karam
I found some linux governor tweaking tips in this website. http://www.ibm.com/developerworks/li...req-3/?ca=drs-

Its a very long and detail guide with lots of comparing graphs. I couldn't read the full guide. But it concludes with tweaking the conservative governor's up & down threshold which seems to have a significant effect on battery saving.

"overclock" profile of batterypatch uses conservative governor. I wasn't using it for a while because I changed it to ondemand. But today I thought about giving it a try. Then I find that first time the conservative governor loads with its default parameters ignoring the "overclock" profile & always remains that way.

Code:

up_threshold = 80
down_threshold = 20
freq_step = 5
ignore_nice_load = 0
sampling_down_factor = 1 
sampling_rate = 3000000
sampling_rate_max = 1500000000
sampling_min = 1500000

now Im testing these tweaks

Code:

echo 98 > /sys/devices/system/cpu/cpu0/cpufreq/conservative/up_threshold

echo 95 > /sys/devices/system/cpu/cpu0/cpufreq/conservative/down_threshold


echo 1 > /sys/devices/system/cpu/cpu0/cpufreq/conservative/ignore_nice_load

underclock profile uses ondemand governor and it loads ok. so no need to change that. Lets hope it works well.

this seems to be very exciting
it should give a huge improvements
testing them too

btw you can add

echo 1500000 > /sys/devices/system/cpu/cpu0/cpufreq/conserva
tive/sampling_rate

and i will release a new package batterypatch-testing
including all the untested tweaks

EVERYONE
i have released a new HUGE update

many many changes and new features
in short ... the continues time of usage must be at least doubled !!

PS: changed MAXFREQ to 900

tested the codes given by carbonjha no problems appeared
tested with HD record/watch and everything works fine

PS2: this might be the last update for 5 months except fixing bugs
have some studies to finish

/karam

//EDIT :
please report if any problems happens with you

yes .. the lastest update surely got huge improvements. but in my case the touch vibration is harder now and the response is little late.

well try to increase the minfreq in overclock from 250 to 500
perhaps this solves your problem

although i have the vibration acts normally

//edit

how to :

install any text editor ex: leafpad

then

Code:

sudo gainroot
leafpad /usr/share/kernel-power-settings/overclock

and change MINFREQ=250 to MINFREQ=500

save and exit
PS: no need to reboot
