I'm glad both ulv kernels are running smooth on my n900.

Since flashing from N900 xterminal I only get "-40" from temp1.
I tried the kernel with 825 and 900MHz, but II always get "-40" from temp1.

just an update: lehto's undervolting 800mhz overclock works! i had to disable smartreflex for the n900 to boot.
ps: any thoughts on the power savings of undervoltage vs smartreflex? seems like if i want undervoltage i have to turn off smartreflex, which one would give better battery life?

Blah blah blah...if/when i learn anything that lends more data and less thoughts on the matter, i'll share.

Classic example of arbitrary Nokia decision making. Couldn't just fallback to the no brainer of tagging with lat/lon if network isn't accessible, could you Nokia?

technically, i shouldn't have the time to muck around with o/c kernels since i have a final research paper due! oh well, my haphazard prioritisation at work,

SmartReflex will lower voltage dynamically. Dynamic MHz + dynamic voltage = better battery life.

I'm trying to Use the kernel TITAN.
I have no idea how to do it properly.
Where should I put this code?
"Code:
wget http://maemory.com/N900/overclock/ke...mo20_armel.deb
wget http://maemory.com/N900/overclock/ke...mo20_armel.deb
wget http://maemory.com/N900/overclock/ke...mo20_armel.deb
dpkg-i kernel-m *
dpkg-i kernel-f *
halt "
which file should I download?
Need flash-kernel 3.5 for Putting on the N900?

@maykon:
That 'code' is the list of steps that you should do at the command line. Open an xterm, become root, enter all 6 lines exactly as specified.
But you should be aware of all the caveats, basically summed up in big letters on this page: http://www.saunalahti.fi/crailt/

But if you know so little about Linux I think you should not try overclocking your device
because you can seriously damage your N900 if you don't know what you're doing.
