Once you overclock your device, does your N900 still update the firmware automatically?

Since then, I see Maemo5 PR1.1 update available HAM. Even with overclocked kernels.
I can't install it right now as I don't have enough free rootfs. =P
Anyways, to answer your questions, I'm sure the OTA update will show up and install fine still.

So, it will silently replace your kernel.

hi
ok - did an on-device flash of the kernel :
* do a backup, have a pc nearby and know you are able to flash the n900 with flasher-3.5 - just in case
* on device :
- start "softupd -vv -s --local" within xterm as root (thats double v)
- open new terminal
- start "flasher --local -f -k <kernel_zimage_file_with_path>"
- you see the flashing - some secs
- type "sync" to be save all is stored to the discs
- type "reboot" and enter to restart
ciao and good luck
ps: the 800mhz kernel is not that much faster - than a 600mhz. i leave it anyway as it may increase battery life - i am not such a gamer - so probably the effect in overclocking is not dramatic then !

I was just wondering.. is there a way to OC the graphics chip? PoverVR SGX530? I have a video compressed with xvid at 1.6 Mbps and the playback isn't smooth even though the cpu usage is about 80 % (900/500 MHz kernel). Would overclocking vga help? I know that the extra heat would probably fry the phone, I'm just curious.
// Never mind, xvid is probably badly optimized. h264 at 2 Mbps average L3.0@baseline plays just fine even at stock cpu/dsp.

on other note
can someone link me to the post on how to flash new kernel or quote,or copy and paste in here i would really be thankful

ERROR: ioctl(SIOCSIFMTU): No such device

What IP interface it tries to open?
EDIT: never mind, just use
softupd -vv -s --local

The Pre has an OMAP 3430 rated at 600MHz. There is a 720MHz version of the OMAP3430 available, but it is not in the Pre. There is a different OMAP chip which runs at 800MHz, again it is not in the Pre.
Running a 600MHz OMAP at 720MHz reduces the lifetime from 100K hours to 44K hours according to the manufacturer data-sheet. It is not known how much further running at 800MHz reduces the lifetime. Note that even when running the OMAP3430 at 600MHz, the operating point is referred to in the manufacturer data-sheet as "OPP5: Overdrive".
Note that going from 720MHz to 800MHz increases the core voltage by the same amount as going from 500MHz to 720MHz, so one might expect a similar reduction again, perhaps to ~20K hours, but that is pure conjecture as the data is not publicly available from the manufacturer.

I've just found this info for the Palm Pre which has the same CPU specs like the N900. Can someone confirm the above mentioned numbers?
One thing is for sure in my case. I wont be using this phone in 2 years. there will be something better about.
Id be happy with 20,000 hours cpu lifetime so overclocking isnt a problem for me.
Hopefully i wont burn it out until Q4 when something better will be available

Without SmartReflex enabled, isn't the processor always operating at the highest voltage (OPP5)?
