I bought raspberry 2b for 600r, I think the RAM chip should be waving on it, since it costs separately. Which 2GB chip is suitable? Does percents support chips more than 1GB, who have datasheet plz look.

[kusjanja]

i9192 (90.95) c 8 to 16, but the operative will not change.
With MTK, it's a little easier to change, but everything depends on the preloader.

There are 2 boards, I watched reviews, I decided to resurrect Lenova. But on htc, as I understood, ordering memory as long as there is no sense

If there are no progers (they are boxes), then you will not lift htc, because it will not call. + Need the correct layout of the flash drive. With lenovo it's easier because they have a flasher sews all the memory, but again the question is about the names.

There was such an experience earlier. On the old X5A tablet, the memory (RAM) doubled by picking up compatible chips. Up to 512MB
Then he really came to life, Dancing was only with the replacement of the core. 2.6 more than 256M did not support, then managed to pick up from some Coby
But the experience is positive.
Right now, the HTC Primo was thinking to revive. It has 512 memory and corny is not enough. Mikruhu picked up the specification for 1GB. But much more difficult. Since the memory is not separate, but eMMC + LPDDR2. Those. You will need a programmer to tear off the dump from the old flash and fill it with a new one. And because of one time buying a Riff, Octopus or Z3x is expensive.
I'm looking for some kind of budget way to perezalit dump

Interested in the possibility of replacing RAM / ROM / processor in the SonyEricsson MK16i. But due to the lack of knowledge, I get a little confused in basic things, plz do a little educational program:

1. What is tied to the stock firmware (only there are the correct drivers for the communication module, Bluetooth, cameras, and, most importantly, the hardware keyboard). Will the factory firmware go in conjunction with another processor?
2. Will the factory processor go in conjunction with another RAM chip?
3. And what about the ROM memory?

Well, in general, tell me what types of RAM are there, whether the RAM chip is checked in the bootloader or at a later stage of the OS boot, etc.

P.S. Kernels like in the framework of the XPeria project are generally available for download, although for newer models. Perhaps there some information can be gathered.

P.P.S. The smartphone is big and thick, there is an assumption that problems with overheating should not occur when installing a faster processor, if this is possible in principle.

venom40rus, venom40rus,I have a couple of questions about soldering and replacing, how would we contact you?

[volk112]

Good day to all! In advance, I'm sorry if I wrote off topic:
There is a tablet on Windows 10 with 32 GB of memory, this is not enough!
I do not want to add using micro SD. This is a separate section, etc ...
Question: Is it possible to increase the volume by replacing flash chips?
Tablet: Digma 3G 1800, Prots: 1.8Ghz (Turbo), RAM: 2Gb ...

and there is no ssd?

volk112,
would you at least have a photo of the board in normal resolution, or else hz what have you got there.

Hello to all! Tell me on samsung galaxy a3 (300f) 2015 you can change the chip with a large amount of RAM? For example, take from a3 (300fu) of the European version, or what other options it may have.

[Arhimed2007]

The people, you sho for the questions of the shaman? You can, you can not ...

It's easy to learn!
1. First, we take the datasheet on the processor and see what its address space is in general and it, respectively, it can address in principle. If the volume of interest is attainable, see -
2. The organization of the memory chip (how many KB for how much, for example, 2048 x 16, etc.) and, mainly, the number of address feet. If on the cards of the board (and among the bus lines of the address) there are fewer of them than on the chip, it definitely does not fit, although the volume that can be addressed, i.e. a piece of chip just won't be available. (besides, "hanging" pins are fraught with glitches!) If the chip organization is different, it cannot function normally in principle.
3. If you are lucky and physically you can stick a chip with a larger volume, you still need to pick it up - find the right size and with the appropriate pinout.
4. And if you managed to do all this, you know how to use the soldering station and bga stencils, and you have it all, the chip has been soldered and wound up normally - this is where the software limitations come up,if any are present.But this is a question more to Android experts - where is the constant that determines the maximum memory. Usually it is one for the whole OS, i.e. Knowing the offset in the firmware, you can replace it, it is possible to recalculate the checksum and score in the required bytes. In general, this is to the system analyst! :)

Those. suitable models are those with a number of address bus lines, pinout and the form factor of a memory chip coincide with similar chips of a larger volume. And volume detection occurs automatically, as in a PC. All other options are fraught with dances with a tambourine.

Good day!
There is a rcmemory pc3200 ddr 512MB rc12d381ta-32cc0607s line which has 8 cans of rc12d081ta0-27bc, I can't find any datasheets.
The question is: can this line serve as a donor to replace the memory chip Zentel A3S56D40FTP, it is necessary for modding the router, increase the RAM.
I suspect that I will not receive it, because the donor is supposedly 32-bit, and what’s installed is 16-bit. But this is only a guess, I would like specifics.

people have it4Good Light AT300 - Discussion (Post Niko_Belic # 66269968)body, replaced the memory on it with a larger size and now after proshtvki it lives only until the reboot, then the brick. How to solve this problem?

Hello! I read here that rockchip rk3066 supports up to 2 GB of RAM, 1 GB of soldered on the m101w tablet, who knows if it is possible to rewrite the RAM chip without extra “dancing” to 2 GB or is it a stupid idea?

[Bigfishczy]

To get started, find out the cost, maybe the desire will immediately disappear.

Do not ... do not disappear. Our people are inquisitive.

Hello, there is an Asus vivo tab note 8 m80ta, with 2 gigs of ram, there is an idea to re-solder these two chips of 1 GB to 2 chips of 2 GB each. It turns out such a focus, as you think?

[sezar167]

Changed ems on a Chinese tablet, no problems. I asked and that's it. I want to torment the motorola processor another, the result is unknown

[arkhangelvasily]

So in order .... RAM is of different types on smartphones. It can be on the board as a separate independent chip, it can be on the board as a separate one installed on the processor (on top of the processor), and maybe combined with ROM memory in one chip in emmc or nand, call it what you want ... Any memory can be increased using bga soldering if you have skills in this direction and reball, but you should definitely take into account that the firmware of the device may see an increase in RAM and start working with it quietly, or may not see it because firmware is in the memory markup Exposed limits that actually have to change and be sewn. All this will deprive you of the warranty on the device, and if you still have to change the limits in the memory markup, then you can forget about updates over the air too, because Your device configuration will actually be changed ...

Is it possible to replace the internal 8GB with 16, and increase the RAM from 1.5 to 2GB?
