are you using Queen Beecon widget for 250/850mhz to set it up?

I'm lost in Space...sorry but how I can check the pmconfig and what I have to do with that ...

NO , i just used the command kernel-config load 250 850 just one time and then used the temprarature script

I don't think you need to flash your eMMC, rootfs should be sufficient

Some possible causes of dpkg db corruptions could be:
* undervolting lead to data corruption
* dpkg db was moved to /home and the new MMC bouncing damaged it (unlikely, this feature is default on most Linux distros)
* crash+reboot during dpkg operation

@titan:

according to the wiki, your LV settings has almost the same voltages as the stock kernel, though the 1GHz freq still sits in 1.35 volts.

in the much low volts settings (ULV and XLV) the freq stays at max freq most of the time if running an app (ei. vgba) which is normal due to low voltage.

is the LV setting does the same?

Been running the v27 for ages @ 900mhz with no problems whatsoever. Then I upgraded to v34 and upped it to 1ghz and changed the up thresold to 75% and the latency to 150ms.

Played some prboom, angry birds, streamed some h264 content - no problems at all. I felt convinced that everything was stable.

Then I was browsing for some time while having a few other applications open, and just as I touched the screen to scroll *BAM!* Reboot.

Can this really be OC related or is it more likely due to me using the JIT options in MicroB or something? (been doing that for ages with no problems though)

Have you guys experienced your OC'ed devices got less stable as the battery level dropped?

Due to many requests, here are all the Queen Beecon Widget exports that I use as seen below:
(I have zipped up each widget's export output as a txt file)

UPDATE May 2013: Fellow TMO user Tangent has sent me an updated version of the beecon widget exports that work with rootsh and with an extra DSP widget as well! New file has been attached. (Beecon Updated.zip)

Beecon Updated screenshot:


INSTALL STEPS

0. Download the attachment posted at beginning of that post and extract its contents. Then copy the TXT files into any folder in N900. (just create a folder called 'Beecon Exports' or something)
1. Install rootsh (latest version will do)
2. Install QBW (latest version is 1.9.7 or something)
3. Create a new QBW widget on the desktop
4. Go to settings of that widget (tool icon)
5. click advanced
6. click yes
7. scroll way down
8. click Import File to Buffer
9. Select the txt file you want to enable (eg. stock)
10. click Import Buffer to Beecon
11. done. now exit out and click Save.
12. Now you have a STOCK widget.

Do the same for ideal.txt and ideal_1000
Do the same up to step 11 for other non OC widgets

You can edit the cmd for ideal and ideal_1000 once they are created to suit your needs or loading your own profiles. (as some people have issues with stability when using ideal voltage profile) I recommend trying lv or ulv instead of ideal for those people.

For those who get the msg "rootsh is now deprecated....", see following post for more info.
(or try out the updated widget exports that I have attached on 31st May 2013 thanks to Tangent)

Please do note that the 1Ghz widget is using a custom profile.
To get it to work, you will need to run the following from xterminal first and create the modified ideal profile that is clocked up to 1Ghz. (example is using ideal voltage profile)

1. Launch xterminal
2. root
3. kernel-config load ideal
4. kernel-config limits 500 1000
5. kernel-config save ideal_1000

(You can change the "ideal" to "lv" or "ulv" if ideal makes your N900 unstable and then change the cmd in the widget to load that profile which you may have named it different - eg. lv_1000)

Automatic Widget Update
From QBW 1.94 onwards, you can now utilize DBUS calls to affect another qbw widget from another. (means you don't have to tap the cpu frequency widget everytime you change the overclock to see the new max frequency. It will auto-update whenever overclock widget is used to change speeds)

http://talk.maemo.org/showpost.php?p...postcount=4017

Basically, append follow code at the end of the cmd:

Where X is the id number of the cpufreq widget.

Again thank you for posting your settings.
I only got a problem following the steps. I did everything except I did the following:

1. Launch xterminal
sudo gainroot
2. kernel-config load ideal
3. kernel-config limits 500 1000
4. kernel-config save ideal_1000[/QUOTE]

I did the sudo gainroot because I got an error the first time I tried to load the ideal settings.
I now get an error once I press one of the kernel settings widgets.

Still having problems with V34. Not only does it revert back to stock 250 - 600 when making phone calls. When I activate ideal config it also reverts back when opening the browser. Very strange bit of background.
Had Ver32 installed with same problems deinstalled and installed ver 34 no modifications etc/pmconfig file is untouched. Even setting cpu to say 900 max manually reverts back to stock when I initciate a call receive a call or open the browser.
Any suggestions.

is it safe to overclock.. for a NOOB.. ?
