Re: overclocking (or not) census
 

Personally, since I love games and emulators, overclocking is a must. I never go over 900mhz though.

Re: overclocking (or not) census
 

I was running mine @ 1150mhz, then i think my screen died, im still waiting on Nokia to tell me whats wrong.

Re: overclocking (or not) census
 

I'm using PR1.3, Power Kernel v.46, and have been running 250-950 since a week or two after I bought it.
I can get it running stably at 1150, but as it gets warm to the touch at 1000 or above, I've opted for 950 as my default.
Note that I'm running it slightly above starving with custom-tweaked voltages, and have no issues whatsoever.
(Aside from a screen crack, but that's not OC-related...)

I've also changed the polling interval to 100ms(from 300), and changed the up-threshold to 50% from 90%.
This, plus changing the transitions a bit, has greatly increased the fluidity of my setup, and I get reasonable battery life(several days doing nothing, 8+ hours of reading with mid brightness, 4-6 of internet, as a rough estimate).

Re: overclocking (or not) census
 

The changes to the Nokia kernel which drastically improved battery life were added to power-kernel a couple of weeks after PR1.3 shipped. I can't remember exactly which version, but v45 and v46 definitely have them.

Nokia's PR1.3 kernel finally included a couple of upstream bug fixes for SmartReflex, a feature which makes an appreciable difference to battery life. For maximum longevity with power-kernel you can enable the two SMARTREFLEX_VDD? settings, but be aware that this will adversely affect the maximum clock speed you can stably sustain. I had to drop from 950MHz to 750MHz, but I get 36-48 hours with WiFi connected and 15 minute mail checks.

I tried ULV 250 - 900 Mhz -profile and got DSP-problems. Wasn't so simple to get the system back to normal.

Re: overclocking (or not) census
 

well 125 (at the moment) is looking like a decent poll size. decent enough for the tv ads that claim 9 out of ten cats noticed a visible difference in skin rejuvenation anyway! ;) and its interesting to note that still less than a quarter of users here dont overclock at all. with the majority overclocking at a perceived "safe" level under 900mhz. i'll let you draw your own conclusions as to what this means in real terms., but the more votes keep coming in the more accurate picture we can build.

Re: overclocking (or not) census
 

I did not install PR1.3 several weeks after it came out. I was analising. I have two N900, and first I updated one of them and tested. The battery on PR1.3 stock was almost equal to PR1.2 with power kernel. I could not believe it. The two N900 had Smartreflex enabled (I always always enable it).

After a 5 days, the power kernel v46 was out, but the results was similar. I updated the second N900 to see if the battery last equal from the first N900 or maybe it was just luck, better CPU chip or something. But my surprise is that I put the two N900 to compete. The battery on standby was amaizing, like 1% battery drain per hour.

From that moment I decided not to install power kernel. BUT, I would like to be able to enable 125mhz frecuency and 700mhz and 750mhz frecuency because some times we need a little more power to do some things, but since I don't have power kernel I'm stock because everytime I try to edit the files for that matter, they do not change.

Can you help me?

Re: overclocking (or not) census
 

My current "optimum" (?) power-settings are lv-profile, 250-900 Mhz, vdd2 SmartReflex enabled:
If I would enable vdd1, the system will crash.

If I have tried ulv- or xlv-profiles, DSP doesn't get enough power and many things won't work, but it won't immediately crash either.

If I do not overclock, (this I am not sure) both SmartReflex settings vdd1&2 can be enabled.

Re: overclocking (or not) census
 

No overclocking here (no need for that, since I'm not running emulators or any of that really CPU intensive stuff),
