I knew you could do it, waiting patiently. (Nothing else to do but work )Fishbong posted on May 31 2006 at 03:38 PM said:Ok, now i know what to do. Just one day patience until i get the required parts...
My GP2X can reach 290 - 285 MHz right now. (depends on the software) I´m happy if i can clock to 310 MHz after i modded it. It´s also possible that nothing will changelippy posted on May 31 2006 at 11:24 PM said:Taking bets to what mhz he can get it to!!!...I'm putting my money on 342!
I haven´t figured out how to increase the voltage for one core separately. It would probably not work anyway, since the cores have to communicate with the same voltage, so raising the voltage for one core would most probably result in huge problems.Epicenter posted on May 31 2006 at 11:53 PM said:Don't get too over-zealous ... if that's not a 266 MHz part marked down it's unlikely he'd get past 300 MHz. I do have high hopes for my unit that reaches 317 MHz in short bursts though, of achieving stability at 320 MHz when I have time to apply a voltage hack to the 920T. In due time..
At any rate I'm having fun just making sure all my code is fast enough to run at 200 MHz! I can see the neat benefits of overclocking later

(Although, the application note says the acceptable range is 1.8 - 3V, not sure if they're just writing typical battery voltages, or if it really won't work properly above 3V in that setup)
mhhhh it would make my life so much easier if it does take 5v
should i risk it though mmhhh
EDIT: I found squidges post but it says nothing about 5v
should i just try?
Seems like i was too optimistic. While i can increase the voltage, it doesn´t seem to have any impact on overclocking. There must be some limitation protecting the cpu, like some diodes...
A strange thing i noticed is that the screen backlight of the GP2X got darker when i cranked up the voltage... not much, but noticeable.
I´ll keep trying. The GP2X power supply is far more complicated than the GP32 one, so it may take time...
