Overclocking With Power Adapter

[thumpgun]

only post your overclocking speed results while using a AC adaptator, was wondering if you can get a higher more stable speed than you would with batteries.

you can probably get the best results using a 3,6v 1a psu, as that is what the chip is rated for.

i think the gp2x crashs at a higher clock speed due to your batteries and not your gp2x....then again im thicker than thicky mick thick, the thickest of the thick..... :blink:

Actually I think it's based off heat..

You may like to know that there's a DC DC convertor inside the gp2x for taking battery voltage of anything between 1.9V and 3.6V* and converting it to a usable internal voltage (3.7V), whereas the DC adaptor input seems to have no such convertor and is used "as is". Obviously the convertor will use a certain amount of current to power itself, but you may find that if you use a decent pair of batteries, the overclock is better than an adaptor (assuming most adaptors are 3V).

* - I don't know the exact range, but providing a 1.9V input directly to the battery compartment provided a perfectly working console. Mapping out the current vs voltage, it seemed that 3.7V was the most efficient.

does that mean that using a LiIon battery would be more efficient?
