Max Overclock

[RockOut]

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).

 

[purple_goat]

250mhz *cries*

 

[yodaofborg]

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.

 

[aapje89]

270 mhz

Mk 1 First Edition - 310, but becomes a little unstable after a while (about 10mins):huh:
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

 

[raiydeck]

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

 

[imhotep]

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.

 

[XaMMaX90]

MK2 256mhz =(

 

[classicgmr]

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

 

[H4k3r4r34l]

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.

 

[halo9]

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!
