when using titans kernel as default, if the device is rebooted more than once in a 5 minute period the stock kernel is loaded, this is to stop reboot loops

no problem mate, now it's time to give me your soul, as agreed :D

Probably a dumb question but why is 1150 the limit? Also has anyone blown up there n900 yet? that will be when things start to get interesting ;)

wellllllll, i think that 1.2GHz can fry the chip, not sure, but i think it might be true, the A8s are made to withstand 1Ghz speeds (the good samples).

for me, i will just go directly to 2Ghz and run windows 7 on it, heck why not, with enough human souls from this forums, i will go to 5GHz, yeah!

on the other hand, if you want to allow both 125MHz and 250Mhz, type this xterm:

echo > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies

if you want to avoid 125MHz, type this:

echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies

i run the ideal config and ramp it up to 1150mhz when i need an extra boost for psx4all but i mostly use a max of 850mhz-1ghz for day to day use.

It's not funny at all; it is expected. Have you read Jakiman's overclocking guide? He actually lists the expected failure rates for each max overclocking level. CPUs are NOT identical, this is known. It's interesting -- you should read up on it.

Ofc, you can go commandos with the battery saving, set the profile to XLV and enable 125Mhz (which uses 0.850), more on that stuff here:

Enjoy :D
is it really that straight forward?

Never done it and I'm not going to.

why not? the arm a8 is meant to run much faster, nokia just underclock it to make the battery life acceptable*cough*
