Does anyone know if the PXA250 chip is a "drop in" or is it soldered into the board? With the various benchmarking posts regarding the Axim on PPC2002 vs. WM2003, I was thinking if it was worth purchasing a PXA255 chip with the 200Mhz bus speed to complement the WM2003 upgrade.....I'm sure it would void the warranty, but....

I would love to do something like that too. But, I think it's a surface mount soldered chip. I'd fry the whole thing trying to put a faster chip in. :rawr:
Remember, Dell is not building these, so they probably don't have the ability to do this. Also given the cost of these, I don't think anyone would want to pay what it would cost to do this considering the shipping both ways and the labor. Even if it is a 10 minute job, they would probably want $20 for the time, plus whatever the chip costs plus shipping. Probably not the bang for the buck you would want.
It's a BGA (ball grid array) package, with a couple hundred miniature solder balls on the bottom of the package. You'd need to heat the entire device to a specific temperature, apply the right amount of pressure with exact alignment... Not really a do-it-yourself job.
I think even though the pinout has stayed the same, some of the electricals have changed. Slightly lower voltage for the chip, I recall. You'd need the upgraded OS ROM image to set this correctly.
CPU mod possible?
Linear Mode
