Default Upgrading ram on Tablets?

I've recently bought a generic chinese tablet, it says it uses DDR3 ram, I've got a few 1gb DDR3's laying around my room and was wondering if it was possible to do that upgrade? I would try it now but I don't know how to take the case off of this damn thing ._. when I figure it out I'm going to try it and I'll update this thread.

But my question is umm, has anyone here ever upgraded the ram on their tablets? If you have was it difficult? did you have to be a specific type of ram? did it make it any better? Hopefully I get some replies.

Generic Chinese? DDR3? I doubt as my S3 still only has DDR2.

Notebook and desktop have different RAM sticks. I suspect tablets also. I suspect maybe even soldered.

I don't know for sure.

I finally figured out how to open the thing up, no DDR3 anywhere haha, I figured it was a bunch of BS that they just threw in there, I guess I go without upgrades to this thing. oh wells.

Also I heard soldered ram chips aren't exactly... replaceable lol. I would assume the failure rate on those are extremely high if anyone actually tried that type of upgrade.

Wanna trade that S3 for a generic $99 chinese tablet? come onnnn you know you want to

Yup soldered RAM is not meant to be replaced or upgraded. Probably find that the board was only designed to take one type of RAM chip anyway, so even if you could get it unsoldered, very doubtful if larger capacity RAM chips would fit or work.

Default Android tablet hardware upgrading

I know this thread is cracking on but it is still relevant I suppose so i will add my two pennies worth!

The installed chip-sets in the device have to be referenced in the firmware by more than just its model / code numbers.

In the case of RAM there is usually a file called 'DDR.ini' which along with the chip-set I.D and size contains the perimeters of the module.

Here is the first few lines of a very long 'DDR.ini' file:
[DDRCount]
Count=6

[0]
ddrName = micron 16x128x2 512M
ddrcRegConfNum = 0x23

ddrcRegAddr[0] = 0x60011000
ddrcRegVal[0] = 0x1370020

So if you were to go and add another RAM chip I would guess the outcome would be one of the following:

  1. The RAM would not be referenced in the 'DDR.ini' file so the tablet wouldn't even know it was there.
  2. It would know it was there but couldn't understand what it was or how to configure it and it would likely not boot.
  3. The 3rd and most likely outcome (even if you had the 'DDR.ini' file from the firmware of the better model, you knew the same RAM chips were used and you managed to re-package the firmware flash and overcome the MD5 hashes!) it will still very likely not be picked up because the manufacturer would not have installed all the other tiny inline SMD components that allow the device to use it!
It is a shame though when so many devices could have been easily ten times better had the manufacturer of doubled / trebled the hardware which would have been an extra cost of about 2% for them.


Thing to remember is though that an extra 2% cost for the manufacturer means a substantially higher one for the end user!

Why? I dunno!

But that might be 20c (USD) per device with make. We're making 50,000 logic boards for these things, that's going to cost us $10,000. Nope can't do that. That $10,000 might be their total profit on the whole deal. I know how it works.

We don't care about the end user, as long as we shift these things on Ebay or in a Hong Kong tech mall.
