Re: Overclock the N900?

My Results @ 1000/480 (cpu/dsp)
- Takes 22 seconds from poweron till bootvid starts playing.
- TweeGo login screen comes up within 5 seconds of launch.

Fennec Nightly Build Browser
- SunSpider = 10479.6ms +/- 7.3% (over wifi)
- Jsbenchmark = 40 (over wifi - best out of 10 goes)

MicroB Browser
- SunSpider = 22710.4ms +/- 2.1% (over wifi)
- Jsbenchmark = 28 (over wifi - best out of 10 goes)

Re: Overclock the N900?

Iv just loaded the stock kernel back onto my device via apt-get but in settings>about it still shows unknown? iv flashed back to 750mhz now tho as the stock is slow after using the new 1s lol, is there anyway to have the info return in the about?

Thanks xgrind and zlatokosi~

Re: Overclock the N900?

Hi all.

This is my first post here. I'm no linux guru but..

You can easily adjust the frequency using the command line by adjusting the automatic frequency scaler.

Example:

echo 500000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

This will give you 500mhz max.

This can be helpful if you have a 900mhz kernel but you want to save battery and/or CPU life.

You can also use other values used in the kernel (example for 900mhz kernel: 125000, 250000, 500000, 550000, 900000)

:)

Probably a full re-flash inc. kernel would get the phone data back, I'm kind of more interested in how some of the users managed to keep the phone info intact after flashing the o/c'ed kernel...

I am currently running the Lehto 125-900mhz kernel

If increasing the clock speed increases the temperature inside the phone, the signal to noise ratio in the GSM receiver will decrease, as the thermal noise level will increase.

If yes, then someone could create a widget or something like the brightness applet, for owner to adjust the clock by simple touch. So, it can be adjust base on demand.
Example: when there's need for more processing power, just tap to higher clock speed.
After using, tap back to stock clock speed or lower.
(Something like the clock speed adjustment for PSP CFW).

No, you can only adjust the speed within the range set in the kernel.

Yes, but set a Kernel at max 1ghz and set a default value at 600 and we´re off to go!

Re: Overclock the N900?

I have uploaded a new experimental community kernel that supports 250,500,550,600,700,750,800,850,900,1000MHz, but keeps the default max. at stable 600MHz.
You can manually increase the limit without reflashing until your device fries :)
