No, it will just crash, most of them can goto 266-300mhz.

It'll get unstable if you go too high, but will crash before it can cause itself any damage. As long as you don't touch the voltage, you'll be fine.

oh em gee
when i overclock to 300, the cpu program just freezes =( i can do 266 but any higher and i just freeze =(

Yea 266 sometimes crashes me when i use the snes emulator, and my batteries drain alot faster too so take that in to account (and I use 2500mAH ones)
Paradox
oh em gee
not possible to overclock the second processor?

of course it is. no use really atm.
Paradox
oh em gee
well for things which might use the second processor, it would be good too, cpu 1 and cpu 2 both running 266 mhz with PSX emu or SNES would really increase speed significantly (at least with SNES anyway)

But nothing uses both at the moment.
Paradox
oh em gee
i thought squidge snes used the second processor for something

No, but it does use the 2d accelerator for scaling

Man is a reasoning rather than a reasonable animal
the way linux makes use of the second processor is making it difficult for them to use it for anything substantial. I'm sure that once we see them move to HH the second processor will be used much more.

HH stands for "Hardcore Homebrew" (or something like that....). It is something that developers are designing to get direct access to the gp2x hardware without linux. If you don't plan on developing anything then all you really need to know is that it SHOULD make things run much faster and let them use the gp2x to its full potential.
Its not the really the way Linux uses the processor but how Digisys has setup Linux. The second processor isn't even seen by the OS neither is the uper 32 megs of ram. But both are accessable to the programmer if they're willing to put in the effort to send things to them but at the moment no one has.
It was stated in a earlier post on the forum that broke down like this
1 cpu for the system with 32m ram the rest of the system is used for Mplayer
1 cpu and all 64m ram but no Video Playback
2 cpu and ~ 48m ram (second cpu has no cache so you have to use ram) and no Video PlayBack**
** Might have made up that last one but the first to were disscused.

I get mine at about 284 mhz decently stable.. Att 290+ it always crashes.. I don't know, maby it's above average, but I'm still very jelous at 7zark7 and his Über Unit

What are you on about? Mplayer useds the 920 for video decoding and the 940 for audio and in the first 32 megs I think.

I thought it used just the 940 for all of the video both audio and well video.
