the only reason someone would suggest setting a different default profile is to have a faster booting from your N900
so if you dont reboot that much then i suggest doing this

It is far safer IMHO to allow the n900 to boot with the default frequency and use a startup script to OC it. I use a Queen Beecon command that runs on the startup of the desktop.

in my opinion this is the safest it can be

and i would recommend this to all

the problem with an automatic script is it will keep loading the profile even if it made the N900 crash

so make it a manual script
its really simple instead of choosing auto update just click on the profile you like
it will allow you to have more than just one profile
actually i have three profiles which i change between them constantly

It is not necessary to install rootsh. "sudo kernel-config ..." is sufficient.
your first call of kernel-config is "Kernel-config" but should be lowercase.

Hi Guys

My lower frequency always seem to be setting itself to 125 irrespective of whatever frequency I set.

Any ideas on why this is happening and what I should do to avoid this.

Cheers

what is the frequency are you using? and what profile exactly?

60V is a lot for a CPU you know :P

haha so use the lv profile

it will pump up the processor and consume less frequency

That wasn't what I meant.

The voltage is calculated by [V = x * 0.0125 + 0.6]
So when X=60, the voltage will be 60 * 0.0125 + 0.6 = 1.35V, not 60V.

60V is an absurd voltage to go through any CPU. My post was meant to point you at that error
