What is the highest you can overclock your gp2x? (Mine is sadly 247MhZ (although it's better than some i've seen XD))

haha! Mine's faster than yours!!! I can do 250! whoo-hoo!!! lol.

240, but 250 with some emus. Does anybody know why that is?

Heh, I thought mine was slow, I've heard a lot of people say they go to 300 O.o

275 mhz here. but i rarely overclock that high

260MHz... I think it goes higher on AC power.

255MHz on batteries.

260 single core
245 dual core

The most demanding single core emu I have tried is gpSP2X. That is a good one for testing your overclock. Testing stability can take a few hours of game time though.

Edit: I have a Mk2

274 stable

~300MHz stable (MK1)

My Mk1 first edition will do 300 stable as well

MK1 FE - 305 MHz
MK1 FE - 310 MHz
MK2 - 285 MHz
MK2 - 270 MHz

Yes, I now have 4 units

MK1 274 Too. It also depends on the application I try to run.
275 is working for a few seconds.

Why?

MK 2 285 ´´

Well, hard to explain really...

One is for hardware experiments once I have time ( going to chop big chunks of it and drill a few holes for certain thingies )
Another one is going to be an arcade machine... once I have time to build a cabinet
The third one is the one I use for coding/testing purposes and is most of the time wired up to a computer
The fourth one is with me at all times when I'm not at home .

heh!, wasn't that hard to explain after all

Only 250 here (although some emulators can run at 266) with batteries and/or external psu.

Oh and for info -

Mine does 275 MK2

Mine does 250 fairly stable, sometimes 260 as well.

There's little software that needs overclocking over 200Mhz though. I only OC to 240Mhz Payback, Quake2x, DrPocketSNES, and GnGeo.

Mine (mark 1) is unusual. it goes up to 310 stable.

Can squeeze 270 but the batteries come out really hot after that//

275 mhz stable

My batteries Varta 2700 last like 3:30 hours at that high overclock.At 200 mhz until 4:40

My MK1 goes over 300MHz quite easily for most things, but a few applications have to be run at 280MHz.

I've ran mine at over 300Mhz for short testing periods, it never crashed but I didnt test it for any longer than around 10mins. These were mostly single core apps so probably wouldnt get 300Mhz on the most intensive 2 core apps.

I tend to stick most things to 250Mhz though.

mine does 285Mhz stable

280Mhz stable using batteries.
