Simply edit /etc/pandora/conf/cpu.conf with editor of your choice (run with sudo through the terminal, like "sudo mousepad /etc/pandora/conf/cpu.conf").

How far does your 1ghz pandora overclock?

Can this be done with all 1ghz units. Mine is stable at 1,240 ghz for example.Can I clock it higher?

Nope, this is only for those who can reach 1.3GHz and want more (the slider has 1.3 as max possible by default).

I see. Why out of curiousity does it only work for 1,300 mhz units?
It works with your machine as well, but it doesn't help.
It's all down to manufacturing variations and tolerances: Some chips can work at a clock speed of 1300 or even higher, and some can't. The only way to find out is to try, which is most easily done through a setting somewhere in the user interface.
Notaz' suggestion refers to raising the maximum frequency which that user interface widget will let you try. It has nothing to do with what frequency will work or not work on your machine. If your chip becomes unstable above 1240, you can use his method to try 1320, but you already know it's not going to work. If, however, someone's pandora does work all the way up to 1300, it might be interesting to try an even higher clock rate; and editing the file notaz pointed to is the easiest way to have a go.

Haven't pushed mine to the edge yet, but it was comfortable at 1200Mhz at Opp5, now reduced to Opp4 and still good.
Everything is so much slicker, smoother and faster. It's the Pandora experience but polished, which is more or less what I expected. StarCraft isn't playable, though, perhaps a distant future magical WINE/QEMU bonding will make that happen... otherwise the Pandora 2 surely will.

I pushed two 1Ghz at 1200 at the GamesCom without problem.
Indeed, SCBW is still not fullspeed, but, of course, better.

For my unit it does not matter if opp3 or opp5...

Mine can reach 1250 without freezing.
Tested with 720p video playback, various emulators and games.
I was on vacation, so I didn't have that much time to play with the settings and so I didn't look how to change the OPP level, will do that in the next few days.

Got mine verry stable at 1210 MHz opp3 on many test , at 1220 / 1230 MHz it becomes unstable and if i go higher the Pandora freezes.
Set to the Max opp5 does no effect on the Pandora , same thing at 1220/1230 MHz becomes unstable and higher it will freeze.
I found out if i set to opp5 via the Pandora Menu "CPU-Settings" , the File "cpu_opp_max" in
/proc/pandora/ is always set to "4" and not at "5" , the File Seems to be write protected for me.
Tryed "sudo mousepad cpu_opp_max" in the Terminal and changed it from "4" to "5" and saved the Config File.
After that it doesn't work , the File is always set to "4" inside there , it shows me only "3" or "4" that i have set over
the Pandora Menu , but never got "5" at opp5 by the Menu settings , (i'm using SuperZaxxonFinal 1.51) .
By the way 1210 MHz is realy much fast for me, and no need to overvolting the CPU ^_^

Mine is still the slowest in survey, but I'm wondering what you are checking for stability with. I used cpuburn that purposefully runs high voltage instructions - e.g. heavy neon. It appears to clock to 1200+ without issue on some other software.

DM3730 only has 4 OPPs, so you can't set it to 5.
I don't know why it clocks the same on lower OPPs for some, does at least dmesg report the right OPP?

Hm, I find myself slightly confused...
I just ran dmesg out of curiosity
One thing is, max OPP is said to be 4 and three, whatever that may mean...
The other thing is, it says something about OMAP3630:
Is that something it should say?

I didn't know that it has 4 opp's, thank you .
If i set it to opp3 , dmesg shows me : [ 14.276947] platform mpu.0: max OPP set to 3
and if i set it to opp4 , dmesg shows me : [ 14.339782] platform mpu.0: max OPP set to 4
Tryed opp4 same thing from above i've posted, 1220 / 1230 MHz it becomes unstable
,and 1210 MHz is the Max i can set . I prefer rather 1,2 GHz at opp3 ^_^

Nothing good will ever come of Exophase.
OMAP3630 and DM3730 are the same processor die underneath, there was an analyst article that confirmed it (sorry, don't have the link just now). There might be some features disabled but it's really probably more a matter of market branding..
Probably the same story for OMAP34xx vs OMAP35xx - see how they used the one higher odd number both times to denote direct to distributor/low quantity variants? But this time they changed the product line name too.

Ah, thanks Exophase
Good to know that.
