Hi, i´m currently running kernel 37@ideal 1GHZ - no Problems so far

How do i configure the avoid frequencies? I would like to use 250MHZ as lowest freq. The setting 500-1000MHZ drains my battery too fast.

By the way, what does smartreflex do?

i overclocked mine to 500 850hmz with ULV profile, i dont know why but im getting random reboots again.

i solved the probelm by using ULV with v34, but now the problem seems to be back again.

annoying...

anyone please? perhaps ULV is not the most stabel profile? thanks

try this

http://talk.maemo.org/showpost.php?p...postcount=4076

but of course substitute 34 (or 32) instead of 27

Ok new to OC'ing so I am not sure if this is working right. I verified from uname-r that I installed 2.6.28.10power-omap1 then did the following:

/usr/sbin/kernel-load /usr/share/kernel-power-settings/ideal
sudo /usr/sbin/kernel-config show

But this doesn't appear to do anything. Shouldn't this output the current frequency settings? I have kernel-power-settings and PR 1.2 installed.

well, to use ideal 250-1000, best way is to do

Code:

sudo gainroot
kernel-config load ideal
kernel-config limits 250 1000

and to make it your default

Code:

kernel-config save myconfig
kernel-config default myconfig

BTW It is my impression that "ideal" means the same settings like "xlv" only with different limits ... or am I wrong?

hi thanks,but just to know, if im to stay with v37,

do you know what profile and frequency is the most stabe?

i'm using v37, ideal, 250 850, and at the moment im getting random reboots...

thanks

Well, that´s exactly what i did, but it seems that setting "limits" doesn´t touch avoid frequencies. I could use the "lv profile", but "ideal" works fine for me.

ulv and ideal have almost same voltage setting so change to lv.
Core voltage settings

EDIT:
One reason could be OC + power supply capacitors ageing. Ageing will decrease capacitance of capacitors and increase ripple and dips on power supplies. If voltage gets too low too long period, it will cause reset. Device might run well at low voltages at beginning, but when it gets older it will need more voltage to compensate ripple (voltage/current dips).

Also depends very much on OMAP quality. There are processors that are better that the other, so it depends very much how lucky you are.

hi, thanks for your advice, but how come most people can get theirs to work with 'ideal' ? are the hardwares different in some ways?
