This is what there is inside

enable_off_mode 1
sleep_while_idle 1
sr_vdd1_autocomp 0
sr_vdd2_autocomp 0
clocks_off_while_idle 1
voltage_off_while_idle 1
scaling_governor ondemand
scaling_max_freq 600000
scaling_min_freq 250000
slee_ind 1

Are the fileds that i have to edit the fileds related to vdd1 and vdd2?

To set a max freq of 850 MHz have I to type 850000, right?

Sorry for the stupid questions, guys, i'm a newbie. N900 is my first approach to the linux world and i'm still learning everything

d!

For 250-850 with smart reflex do this:

Code:

enable_off_mode 1
sleep_while_idle 1
sr_vdd1_autocomp 1
sr_vdd2_autocomp 1
clocks_off_while_idle 1
voltage_off_while_idle 1
scaling_governor ondemand
scaling_max_freq 850000
scaling_min_freq 250000
slee_ind 1

yesterday after reading this thread i followed vi_ advice
http://talk.maemo.org/showpost.php?p...postcount=2736
removed qcputweak and kernel-power-settings (gave up on wonder patches a few flashes ago) and i'm getting some great battery life including usage and standby with power v49. cheers to everyone involved with kernel power and to vi_ for this information

Should I remove kernel power SETTINGS too? I've installed it..

Anyway, is going better for me now!

Not exactly true - afaik, if You want to edit correlation between CPU speed and max DSP speed, You need kernel-power-settings (see 720p video recording). If I'm wrong, feel free to correct me.

/Estel

AFAIK: Kernel-power-settings is mainly scripts and a command line-tool used to ease maintenance of multiple kernel configurations. It has about 8 built-in configs, and the kernel-config tool that lets you load configs or change them on the fly. You can do everything this package does by editing /etc/pmconfig and rebooting, or by touching /dev or /sys files. The tool just makes it a little easier for us humans.

Do you need it? No. Does it affect anything if it's there (or not)? Not really. It exists only to make user configuration easier.

random reboot when set up over than 850Mhz,

example
kernel-config limits 500 850(working fine)

kernel-config limits 500 1000(disaster begin)

Uh? What's that got to do with any of this?

The default N900 is like an oven without a dial, just a big "auto-cook" button. The K## packages provide lots of thin metal cylinders you can turn to change the settings, but most can't grip them well enough to use them directly. The settings package is "the big plastic knob" on the front that makes it easier to use. But if you turn the oven up to twice it's rated value and it catches on fire, it's not the plastic knobs fault.

Some devices simply can't operate at faster speeds. It has nothing to do with the tools that configure the system. It's a hardware limitation. Nokia/TI tested these to work up to 600Mhz. Some reboot at 605Mhz, some reboot at 1200Mhz. If your device explodes randomly going over 850Mhz, then don't set it above that. Done.

Highlight the file 'pmconfig' and press the edit button at the bottom of the screen.

Change smart reflex to '1'. Set your frequencys. DO NOT exceed 900MHz!!

Save the file and quit MC.

reboot.

job done, now post some tits.

i followed your steps. By doing this will the default profile will change to this, i mean after reboot max freq. will change to 850 MHz? It didn't happen with me.
