Hah yep! Very fast and clean

... and DO NOT do: apt-get purge facebook and then autoremove . God damned.. It's clean whole phone . So N9 is build on facebook or something..

what is this app. And can i get it somewhere.

conky, there is a link in my signature

Since overclocking my N9's screen stays black. I can only get low power mode screen to show.........?????? This is even after changing settings to default. I turned it off and back on, it seems too be okay now....

Plus, when I first tried this app, my N9 passed 1300mhz test with default voltage, now it cant even do 1200mhz......????????

Anyone else having similar problems???????

Well I once had the same issue with only low power mode screen due to excessive OC or wrong voltage, whatever, but no extra issues like not being able to do previous tested frequencies though.
I'm sure so long as you're using an appropriate voltage with your freq you should be fine, assuming it's not a bug or cpu getting more and more fried from pushing to 1300 etc.

So far 1300mhz with 1375000 voltage has been my lucky numbers. Been running three days now and no problems. Here is what I've tried so far:

1100mhz
1200000V (fine)
1250000v (reboot)
1300000v (reboot)
1350000v (reboot)
1375000v (fine)
1200mhz
1200000v (reboot)
1250000v (reboot)
1300000v (reboot)
1350000v (reboot)
1375000v (fine)
1300mhz
1200000v (fine until I listened to music)
1250000v (reboot)
1350000v (reboot)
1375000v (fine) the best for me so far other than 1100mhz and stock
1400mhz
1375000v (fine for about half a day then reboot)

I still want to try other combos, but don't know about other voltages at higher freqs just yet (1300+). The highest temp my phone has reached via Conky has been 33.5. It hasn't quite warmed up here in the northeast states yet, but the phone is always in my pocket. Again thanks to Creamy and Bigtruck the phone is much much better in every respect of my usage

I got the best performance so far at 1250 MHz with 1275000 µV.
My "benchmarks" are the stress test in opptimizer (23sec for 3000 iterations) and app loading time of Maps (12 sec from clicking the icon to keyboard appearing to search for something).

So Maps loads about 3 times faster than before. Quite good, but still not impressive...
Many other things are a lot faster though (settings, stock browser, keyboard, messages). Twitter seems to be almost unaffected, which is bad. Also Spotify still isn't really fast.

This with SR enabled works for me, thanks

Mine rebooted at that

But if you see my previous post, My N9 wouldnt go past 1200mhz just hours earlier...

Edit: Oh, but I have updated to v1.5.2..........!
