I apologize if this has been asked before, I used the search button.

Anyway, what is your maximum overclock on the GP2X?

I got 290 w/ the cpu speed tester.

EDIT: I have a MK2. Also, this should be stickied so that we can have a sheet of data regarding max overclocks and GP2X type.

Same on the speed test for me, but that equates to 275-280mhz when actually playing something (depending on what that something is).

Although 90% of the time I play at 200mhz.

295

I think mine can get to the low 260s. I'm not really sure. Don't really care either because I almost never set it higher than 200mhz (In fact, if I can, I set it lower).

250mhz *cries*

Can clock to 280 here, and not 1mhz over :/ 280 is great though, for an ebay mk2 model

275 is my safe clock, but it'll go up to 290 with varying stability.

270 mhz

Mk 1 First Edition - 310, but becomes a little unstable after a while (about 10mins)
With stuff like snes, gpsp or psx I usually run it at around 280-300 stable, but it sucks the battery power

260 MHz, but I usually don't overclock it. No need for that with Picodrive

My Mk1 makes 290, any higher and its a bit unstable

My Mk2 works at 265 on SquidgeSNES, but crashes at 270.

If you can, post your GP2X version, guys. The earlier models Mk1 and First Edition seem to overclock higher.

It is likely that the CPU speed tester doesn't test the stable speed. It might be better to try an overclocked speed in a demanding emulator (one that cannot reach full frame rate) for 10 mins.

Mk1, runs at 275 then locks up after 30 minutes.
Runs 266 stable.

MK2 256mhz =(

My MK2 will freeze after 2 minutes at 245MHz. Best I seem to be able to do is about 235-240 MHz.

My MK1 runs stable of the power brick at 315 though it cant get past 320 on the cpu speed tester

After lots of testing on my MK2, 266 stable. 265 not, though - why is this? What is the thing between 265 and 266? It's the only clock frequency that has a +1 difference in most emus. TELL ME THE SECRETS.

266 is the normal speed of the processor. I guess any lower is 'underclocked' to save batteries. Mine clocks up to ~275.

The GP2x uses rejects that aren't gauranteed to meet the minimum clockspeed of the chip at 266mhz. They can all handle 240 from the sounds of it though.

So the GP2X is in fact underclocked by default!

No. They're 200mhz but supposedly tested at 240.

280 mhz more then enough for me

MK2, I run mine at 266 but I have had it running at 270. I haven't tried it any higher than that. Batteries become an issue at that point. I really don't need it running any higher.

Mk1, runs at 245MHz max.

*cries*

how do you run this test

Battery Test

EDIT: LOL, ignore me.. that's what I get for trying to function at 4 in the morning fatdad, just fire up an emulator that lets you select clock speed and keep going up in small increments until your GP2x gets unstable/crashes.

Yes, and run the GP2X for about 10 minutes at each clockspeed to make sure it's stable.

thanks,,was racking my head trying to find it

I get 285 mhz w/ the cpu speed tester, its stable at 270 mhz. Mk2

actually better to work downwards starting at 300 or maybe 280. I mean, algorithmically, you'd finish sooner.

Edit: I'm stupid and can't read

edit: Not to waste this post; I get up to 250 MHz stable, at 266 Mhz i crash after 5-10 minutes.

260Mhz stable

I've gotten up 285Mhz in Squidgenes without crashing, I haven't tried anything higher but its possible it might go up higher.

I'll go ahead and test it whenever I have my GP2X with me.

useing the battery test programe , my results or

mk2 gp2x 1 year old

265mhz 41.34 minutes before it frooze

266mhz frooze after 14 .32 minutes....

im using uniross 2500 rechargeable batteries

any higher and the test screen freezes at start...


edit to add second test results

The mk2 wasn't around a year ago was it?

The MK2 came out in like June...

how come then i got mine last january ,it dose't have first editon wrote on it ,has the white cirles covering the power\battery lights etc?

That's a second edition MK1. I had one until I had to return it.

Quick check, to see which version you have: MK2s have Korean text on the left of the back sticker. Also, the model is marked GPX-GP2X-F100(B).

the wife got it for my birthdat -9 feb,she got in january,

model no:gp2x-f1oo
battery:(aa)1.5vX2
adapter input:3.3v 1a

gamepark holdings co.,ltd
made in korea
ce f cc mic with 2 swirls around mic


thats all it says on the back

It is a second edition MK1, as NickSpoon has said.

is that good or bad?

If you like it, it is good.

285MHZ on my MK1!

MK1 regular, 250

i`ve got my mk2 gp2x today and one of the first thing i tried to overclock - 275 MHz but donno the stable freq yet...

280 stable. Haven't ever bothered to set it any higher

This is on a 1 month old mk2

I thought my stable overclock for my Mk2 was 265, but it's actually 262 by the look of things. Neo Geo emulation seems to be a good way to hammer the CPU in order to judge stability.

I got my MK2 today in the post. Customs charges were £20.38 . But the overclock speed makes up for it. So far I can do 282 - 284 Mhz steady.

I can get a 280 stable on every emu...but batteries dont like 280MHz

see you

I have some 4 Cheap batteries & 4 GP2X Branded batteries. So far my cheap ones seem better.
