Of course, after reboot - new life. The only parameters are preserved which are in flash. Temperature value is in kernel and after reboot it is lost and should be collected again.

Can anyone help? Thanks.

Here.

Code:

sudo gainroot
echo 1000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

This 1000mhz stays only until a phonecall is made or next reboot, its NOT meant to be used all the time... its left in there if for some really odd reason you require 1000mhz of calculating power.

@Letho let me see if I'm getting this right:

IN THEORY you ULV kernel at 800mhz should actually be safer (more battery, more cpu life) than nokia's stock kernel at 600mhz?

I make this assumption based on past statements where they say that the shortlife on the cpu is caused by the increased voltage on the cpu to achieve high frecuencies.

Thanks!!

Trying the new titan kernel with the under voltage enabled and phone enhancements.
When making a phone call the max level currently at 900 stays the same which is good but the min ie 125 always defaults back to 250.
Any one else using 125 confirm.

In theory yes. After all mine runs with about 1.17volts (estimated) compared to the stock 600mhz's 1.35volts.

Titan does not have undervoltage enabled yet.

Damn.. i who hoped it was undervoltaged as it was rock solid.

Just curious to know how have you verified that which core voltage is still OK. What parameters do you monitor?

I have tested your normal (850MHz) and under voltage (800MHz) kernels with good success. Nice job!

Now testing Titan's latest (850MHz) without any troubles and waiting the low voltage version. Nice job too!

Keep on good work!

Thanks and best regards

30minutes 100% load behind charger. When that clock is stable and doesnt crash, I add one more voltage step and then move to next clock.

Ok i've downloaded the file to my N900, so how do I actually use this?
