Upgrade RAM?

header2k · Apr 1, 2012

i think that the ram is in the SoC of many modern phone, but i know that there is an onlineshop offering ram upgrades for _ really_ old Windows Mobile Phones which have seperate RAM blocks (Ball-Grid Array). And i know that there was a chinese tutorial on how to change the ram byself, altough i can't find it anymore.
As ciolansteen mentioned before, you'll need either an expensive device or try your luck with a heatgun in order to upgrade those.

That would be a dream

I think it is possible but not for "private modding"

It really depends on the device.

If it's a device that uses PoP RAM (such as nearly all OMAP devices) - I don't think even AdamOutler could pull off the soldering job required for this. It goes way beyond the normal difficulties of BGA reflowing/soldering.

If it's a device with a separate RAM chip - maybe, but the amount of equipment required will come close to the price of buying a new device.

you can easily do soo

jeffreya93 · Apr 3, 2012

possible

you can do it

Only a full upgrade will do the job(like CPU,GPU etc...)

You've all heard of Swap Partitions, haven't you? Technically, you aren't *replacing* The RAM on your phone, but you could always create a swap on an external sd, probably one with a higher class, so read/write speeds, and storing/recovering information would be much faster.
Just create one, via CWM, or your pc, and boot into the terminal emulator, and type "swap 0". Or, you could just get an app from the market, if you're too lazy to do all that.
Trust me, your phone does seem a tad faster after doing that.

If you've heard of all this, well, Pardonez-moi.

I remember back in 2001 when I was working for a GSM repair workshop that we used to replace bga ic's using this kind of hot air gun. As a conclusion - Yes! It can be done if you have the right set of documentation / tools.

Happy Modding!

Heh, same here - worked for NEC back in the 90s. So much easier to get the BGAs off then back on again...

I don't know if modern phones ever reuse the same boards for diff. models (eg high end with more RAM chips, low end with empty spaces on the board for them), but if they did, upgrading a board to same spec as higher end would stand more chance of success IMO.

So many people saying it's impossible. It's not; nothing is impossible except dividing by zero, and falling in to a black hole and living to tell about it, and... well okay, I guess a lot of things are impossible, but this isn't.

It would however take much more skill and prior knowledge than you probably possess. After all, if you have the resources and knowledge, even if the RAM doesn't exist... you can make it.

Its been done, at least on xda exec

Its really depend on the type of RAM imo, and the availability of the higher density RAM wih same configuration

Not all phones are good with swap (some ROMs in the Galaxy Ace cause bootloops after making a swap).....and especially if your sdcard sucks (like a Class 2 or something)

Answer

In fact,it is impossible..after phone made,it's RAM can't change..

hongromeo · Apr 22, 2012

I think, can't upgrade RAm on any model mobile. because can effect to any device different inside mobile.

PS:Sorry for bad English

If it is possible, share how..

Hairplayer: it's not commonly done but certainly 'possible'. Speaking with friends who've done that sort of thing (on embedded devices, not phones), the hardest thing is getting it all to fit together again, as well as being careful to not short circuit stuff as you solder the new module back in.

Best option: check out the manufacturer of the RAM component (either through the phone's spec sheets or the writing on the component itself) and select the most similar module (same model/line) with more space. Then, desolder, solder in the new chip and cross your fingers. I'm not 100% sure with Android but you may need to slightly modify the ROM as well (less of a problem if you chose a similar chip). It's a bit hit and miss and by no means an exact science, and generally turns out ugly.

If you're interested, check out the dd-wrt forums, these kinds of operations are relatively common on routers (similarly embedded devices). The big difference there is that there's a lot more space to work with there and the components are a little easier to access and more spaced out.

it would be nice if it is possible

mmkaplan · Apr 30, 2012

has anyone been successful at this?

Here you go!

Yep you can also upgrade CPU and GPU.. nuclear powered batteries are also available. My battery is at 91% after 6 months heavy usage.

I think this is impossible, at least without damage your phone
