Integrated CPU Swap? UMPC

[Harrisonj11315]

I recently acquired a UMID MBook SE. Problem is, the CPU is only 1.6 Ghz. The CPU is a Intel Atom Z530 PBGA441 Socket at 1.6 Ghz. I was wondering if i could de-solder the current CPU and swap it with a Intel Atom Z550 which is 2.0 Ghz Single Core same socket, and generally everything else is the same. I checked intel ark for the comparison of the two, they are really the same except they are slightly different in terms of power consumption, but a mobile unit most likely can handle the difference. Or would i just be better off doing a software overclocking with setfsb and have it run on start up, Windows 7 btw.

Successfully unsoldering and resoldering that many pins is unlikely, unless you do that work for a living. Those motherboards are considered non-repairable by the manufacturer. Live with what you have.

NO!. De-soldering requires special equipment, re-soldering requires even more special equipment. Go with what you have.

Mobile devices are built with very tight thermal and power envelopes, any attempt to mess with them, even by trying to overclock, is likely to run into power or heat problems, or both 🙁

How to turn your device into a brick:
Step 1. 'de-solder the current CPU'

I have a reflow station and have successfully swapped gpus on a few laptops such as the dell latitude d630. It is something i can do, just wondering if it would be ideal in this case.

Can the motherboard BIOS and chipset handle a different CPU?
Can the cooling system handle a hotter CPU?
Will you see any actual performance change, going from an Atom Z530 to an Atom Z550?

400 Mhz may be a rather significant change. The cooling tdp is not really different either, and the bios may be fine with a new cpu as umid uses the same bios for all their mbooks and they changed the cpu three times with no bios change as i recollect. But i probably will just forget this idea.

 

[Harrisonj11315]

Ha, anyone have an idea where you could get an OQO Model 03?

 

[USAFRet]

How to get better performance out of that device?
Sell it, and buy the better one.

 

[Harrisonj11315]

The umid mbook se is a quite rare umpc, i could not find any higher end umpc than it unless you can find an oqo model 03.

 

[DonkeyOatie]

There are rare 8-track tape players too. The edge has moved on.

Cheeky, umpc's still are relevant to some, and i was even trying to make it more useful.
