Smartphone + Ln2 ??

Hei.

You've sure heard bout those People disassembling their phones! I wonder if it's possible to modify some Smartphones to run them with a Pot and LN2 XD

Theoretically possible some1 knows how ARM cpu's (SoC....) work with cold temperatures? Maybe they dont like it...

Any idea?

I did with laptops, xbox and xbox 360, but I didn't try any smartphones yet :P

Ich habe keine Ahnung wie sich die Chips unter Kälte verhalten ... witzig wäre es aber schon mal rauszufinden was geschieht, wenn man ein Smartphone kalt macht :)

I don't have a clue how those chips behave at extrem cold ... but sure it would be a shitload of fun finding it out :)

I asked myself the same Question. My HTC HD2 runs @ 1.6 GHZ (instead of 1Ghz). But they tested Smartphones under low temperatures and the most failed. To adjust the Clock we have to write some config file in Linux and recompile the Kernel I think (but i dont know how..).

depends on the SoC and Kernel! i overclocked my Sony Ericsson Xperia X10i from 1ghz to 1.2ghz.
Thats maximum Clock in Kernel! Cuz Phone clocks up to max. frequency at Boot there might be a problem with an unlimited kernel. But i can adjust Voltage in Software.

The Problem with the Smartphones and Cold temperatures doesn't necessarily have to be the SoC! There might be other component's who don't like the cold! maybe you'd have to heat em up and cool only SoC :kopfantisch:


Well, gotta ask some ppl from XDA bout sepcific unlimited Kernel maybe email Qualcomm bout maximal Voltage for SoC and Cold behaviour xD
Also gotta check some Disassembling pictures.. and if Smartphone would still run ^^


When i'll get a new Phone in the nex 2-3 Months i'll try disassembling my phone and see if i could somehow fix a SoC Cooler xD Somebody wanna help ?

Sure, count me in :) This sounds like a lot of fund :D
Btw. have you been thinking about separating the display from the other components? I think this would make fitting a cooler much easier.

Another approach to test overclockability of SoC is looking for other devices. As far as I know there are media players out there which use ARM SoCs. In this case I guess that it would be way easier to fit a cooler :)

well, the overclocking capability is verry different with differen SoC's! Same like with Normal CPU's! my Qualcomm QSD8250 runs up to 1.2ghz ! Same QSD8250 which was produced 1 Year later and is built in another phone manages up to 1.8ghz! Once had a Samsung Galaxy S2 , overclocked that from 1.5 to 1.75ghz. So i'm not sure how much a bigger Voltage would help. Maybe nothing at all! But you newer Know.
