View Full Version : What about changing the CPU?

Most probably it is a very stupid idea but...

The NX80V comes with an Intel PXA 263 running at 200 MHz. According to Intel, the PXA 263 is also available with a 400 MHz clock.

Therefore, it *could* be possible to replace the existing CPU with a more powerful one and use an application like LightSpeed or PXA Clocker to drive it correctly.

Any ideas?

Most likely not possible because the CPU as I understand is onboard.

Unless if you have a master in electrical engineering or something of similar standard it would be very difficult to remove the chipset and install a new one in its place and have it in working coniditon again.

I don't sugguest putting a more power chip in the nx80 anyway because the battery is not very good already when you use it for camera /w flash and other power draining applications, with the extra power you're basically decrease your battery life.

You think that's worth it? What do you need the 400mhz chip for? starcraft? Given it can even run @ 400mhz.

The current CPU i have gotten up to 355 with light speed. Isnt that good enough for you? The seems super fast if i use that for like backups and the such and graphic intense games.

I do not believe it is a matter of "good enough"... You increase the RAM, the CPU, got better program just to discover that CPU and RAM have to be increased and the cycle will repeat.

Just my opinion of course.

The problem with that is... for this change you have to use an special rework station for BGA chips (the same problem with the memory upgrades)... and the rework stations for BGA are not cheap

It is probably a little more complicated, for you have to change the clock frequencey. You might then find that some other component isn't working at that frequency. Also this chip has the flash memory built in, so you would need to be able to copy the content (hopefully without Sony's password) over to the new chip.

Saw that there are some companies doing memory upgrades on some machines (don't remember if they were in HK or the US), but you could contact one and ask about it.
