I would also like to know if there is a specific way to OC now. Also will it drain battery as bad. Before PR1.2 i swear it wasn't that bad or is it just me?
Anyone else OC properly after PR1.2? any new walk throughs or videos?

I've been unable to find joy by over-clocking my PR1.2 device via the kernel-power-settings package:
Background:
I enjoyed noticeable performance and battery gains via Titan's OC-kernels before flashing to PR1.2. I also tried the leaked PR1.2, encountered reliability issues with Exchange Server syncing, and this reverted to the non-overclocked vanilla PR1.1.1 with the up-flashed radios.
It was this install that I then flashed with the official US-version PR1.2, including the vanilla eMMC using flasher3.5exe.
Results:
Attempts to overclock this install via Titan's kernel-power-settings produced frequent system freezes in the browser, in the phone app, in the email app, and when resuming from sleep via the side-slider button (i.e. system would not resume). In all cases of system freeze, I resorted to pulling/re-seating the battery in order to reboot each time.
The only power-settings I explored while doing this were based on the Ideal settings, with limits set to 125/750, 125/850, 125/950, 250/750, 250/850, and 250/950.
Outcome:
I've since de-installed kernel-power-settings and am now running a fresh PR1.2 flash. Battery performance is excellent: as of 5pm today with 8 hours of constant Wifi/3G connectivity and moderate email, browser, witter usage the battery is still close to max.
YMMV.

That said, if you are having problems I doubt they are related to the power kernel. I am using modified Ideal settings (added back 250Mhz min, 1000Mhz max) and for the first time ever I can keep my N900 idle all day and only lose one notch on the battery.
It still drains fast in actual use, but I don't think its any worse than before.

My current overclocked profile (/home/user/.kernel/overclocked) with 0 and 250Mhz added back in is:

All I can say is with my overclocked settings my current uptime is 6 days, 14:26 and counting.

Hmm no wonder it never goes below 500 in Conky. Anyways I had it at 125-800 before pr1.2. What should I put in to get it to go down to 125?

My overclocking experience with the leaked firmware and the legitimate release has been flawless. I'm very happy.

They even recommend you not use ideal until you have tested the others first, as it may be unstable due to using the lowest voltages. I had it crash a few times on PR1.1.1 but not a single crash since PR1.2, but that may also be due to their own changes to the ideal profile in the meantime.

i meant like..
ok scratch that..
i saw premade kernels on internet which jus had to be flashed..
they were based upon stock kernel from pr1.1.1
i think they were called letho's kernel or something
anyways..
point is..
how did he make those?
and i gotta tweak from the inside without flashing coz if i flash the kernel, it says V <unknown> on the *#0000#..
and my issues with titans are that i dont want my mobile to freeze if the slide is open.. *dual boot is buitlin i suppose*
and i still trust the stock kernel rather than a experimental kernel.
