Hello all.
I have a P905 model with 32GB RAM. But I've seen P900 models with 64GB.
Q1: Did the P905 come out with 64GB too, or only 32GB?
Q2: The RAM is probably a surface-mount IC (soldered to the mainboard). I haven't had a reason to open mine yet. Does anyone know where I can obtain a a picture showing which chip is the RAM?
Q3: If some P905 models do come with 64GB, and I find one with a broken screen, is there anything preventing me taking them to a shop with the correct gear to swap the RAM chips? For example, would the RAM size be the only difference, the other ICs the same, so the 64GB RAM will 'just work'? Or is there a second chip that checks the RAM, or something in firmware that will recognize the tablet shouldn't have 64GB and refuse to work?
Q4: I know the mainboards and processors of different models are different. But does anyone know if the RAM chip is the same? (Are 64GB RAM chips from different models compatible with the P905 too?)
Thanks for reading.
Whether you're truly talking about RAM or simply storage, the process, whether leading to successful expansion or not, will require very, very fine skills. You can find videos on YouTube of, for e.g., iPhone upgrade 512GB, MacBook Air 8GB upgrade, etc. The skills required for this type of work aren't likely to be trained overnight, even with the right equipment.
Mainly because of the density of solder balls present for each IC/BGA chip, and their small size. Everything must be perfect.
Thanks. I understand the process but don't own the equipment to rework surface mount components. It's probably come down a lot in price since I last looked but I'd probably only use it a couple of times. Easier/cheaper to go someplace that does it every day. I'll keep an eye out for a broken tablet to try it.

Ok, so we all know the internal memory is way to limited for the amount of apps most people will have on the market. So, I have a crazy idea of finding a tech shop that can do the work, and have them replace the onboard memory chip with a larger one. I am fairly, though not 100%, sure that the OS can handle the larger amount of ram.
What do you guys think, would it be a possibility?

First off, I don't see why you'd want more RAM, I've never seen any app crash cause the phone ran out of RAM, so I'm guessing you're talking about the built in flash storage. Secondly, I'm fairly sure they solder everything onto the motherboard so unless you're looking to do some elite hacking and happen to have a virtually identically sized but larger capacity flash ROM unit lying around, I wouldn't suggest it.

I believe you mis-understood him.
He meant physical storage.
The apps take up space when you have many of them.
And as you may know, there is a limit to how much space is available since the applications are not stored on the Mem. Card but rather internal memory.
He wants to know if there is a way we can increase the internal storage memory size.
Hope I explained it well.
There have been people that have upgraded the soldered SSD drives on the EEE laptops with larger chips, but the problem becomes the controller. It must be programmed, and unless you have access to the company that sells the controller chip you will have a very hard time flashing it. The ones that have upgraded them all had inside help with flashing the controller. I dont know how much of this would cross over to phone, but it definatly isnt as easy as just replacing the chip- and even that requires a shop capable of reflow work
If you think in terms of computers, your not just replacing the stick of memory, your replacing just the chips ON the stick of memory, and then flashing the controller to be able to address it.
I upgraded the RAM in my PALM a few years ago from 4 to 8 meg.
What a nightmare.
Yeah, it seems easier to install apps to the SD card.
It's exactly what's being said here. It isn't that it can't be done, but it isn't just as easy as replacing the onboard RAM module.
In most cases, it is directly soldered to the MOBO, so, you've got to have someone remove the old RAM module, hopefully not destroying anything else in the process, and then run the risk of the system not booting because the controller for the RAM module doesn't recognize the new chip.
It is a complicated process, to say the least, and it COULD be done....but I wouldn't recommend it.
I had the HTC XV6800 and a lot was discussed about upgrading the memory. That was 2 years ago and nothing has happened. With that said I'm sure it is possible, but you would need a lot of resources and it probably isnt worth it. If you need more space you can always move your apps to the sd card. It works quite well and is available today.
I had a Dell Axim x51v upgraded to 128MB RAM. A Friend of mine had a Universal with 128MB too. Not every device could be upgraded though. Some of the devices have empty place on the board where somebody can just soldier a new compatible chip. For some there is empty place, but the existing chips could be exchanged for bigger ones.
But it is possible and had been done for various HTC devices.
The storage is big enaugh and Apps-to-SD is a matter of seconds. Bigger RAM would be invaluable. Now apps keep unloading themselves all the time when you start a new app, which more or less beats the point of having multitasking OS. I would like to be able to start Music, Browser, Skype and AndNav without having to use the slow swap-to-SD.
I purchased an MK809II from eBay. Was having a few issues with it so decided to open the casing to check that it was a real MK809II. After inspection I noticed the PCB was clearly marked as a MK806 V30 model. Can any one confirm if I have a fake/older model? Any help would be great.
126 views and counting, not one person has any information?
As far as I can tell these sticks go by different names from different manufacturers so there is not much (if any) differences between your stick and what any mk809ii sticks apparently have. Same dual core chip, 1GB ram, 4 or 8gb of storage etc. So if it was me I would not worry to much.

Thanks, just thought I was being ripped off with a lower model.
First time when I've ordered Moto X Play (XT1562) with 16 GB of internal storage, it did show 11 GB of available storage. However, due to display defect, I had to return it and get an replacement which has 10.89 GB of available storage.
I've received the replacement before sending the actual defective one. I've tried to check what's different, but I couldn't find anything else except for storage availability difference. Both were Lollipop 5.1.1 with identical kernel and firmware version (both were "reteu" and single SIM). As I didn't know about accessing recovery mode before returning the defective one, I don't know was there any difference in recovery information.
Performance seems to be identical, both were still causing identical lags. Even after upgrading to marshmallow with my current replacement, it's still stuttering while scrolling. It still doesn't feel fully optimized.
I didn't post this before as I thought that this wasn't a big deal, but I want to know what was the difference between storage availability. Does anyone have Moto X Play with 11 GB of available storage? I saw some people having 10.89 GB, but no one having 11 GB. Please check size of your available internal memory storage and give some details if possible. Along with that, vote if you have 16 GB model (If you have 32 GB, don't vote for other value).
What happened to 0.11 GB of storage? Is it anyhow possible to get it back?
Well, mine does have exactly 11GB. Dunno what's the actual reason.
I'd imagine it's the same as anything, all chips are made to a certain spec and not all are bang on. They have tolerances, some maybe 11 and others maybe 10.89 and some may even 11.10 or something. It's the same with CPUs, not all chips are identical I the same range. This is why we CPUs can be over clocked much further than another CPU that is the same model number.
If after a few days you don't see a noticeable performance difference, I'd suggest performing a factory reset. If it still persists, I would send the pone back. Mine went from noticeable lag to occasional stutter (fairly rare, just could be equated to background tasks running).

Mine shows 11.
differences between regions? single, dual sim? just my guess

It's not the same as CPUs.
If you have two same phone models with same CPUs with advertised clock speed at 1 GHz for example, and then you notice that they underclocked it at 800MHz on one phone due to possible instability with higher clock, wouldn't that be unfair?
You can't just sell something advertised with higher specifications and then sell it with lower specifications.
On contrary, if the manufacturer manages to get higher clock on some CPUs, they would sell those as different model with higher advertised clock speed. The example for that would be MSM7227 (600MHz) and MSM7227-1 Turbo (800MHz, same as MSM7227, but works with higher clocks). Some models only use the first one, while other ones use the second one. Two different phone models can have different CPUs, but two same phone models cannot.
It's still 11 and 10.89 GB. No one mentioned anything more or less yet.
You're suggesting something that I didn't ask for. I don't need help with my phone. I need help with finding out what is causing this and is there anything possible to do something with it.

I've already said there was no difference between both phones I had. Same region, both had only single sim slot.
Further note:
I've decided to check with file explorer to see actual partition sizes:
/data: 10.89 GB
/system: 2.57 GB
/cache: 0.73 GB
Total: ~14.19 GB
In case that others have 11 GB of /data, then that would be ~14.3 GB in total for them.
If you can, check /system and /cache partition sizes to see if you get in total about 14.3 GB.
Okay. I'm sorry to have responded and tried to help you out. If you think that I don't know what I'm talking about then I'd say you are obviously qualified to figure this out your self. I wasn't trying to be rude, just trying to explain that there are tolerances in ICs that are followed. They have gotten a lot better than when CPUs were first being built, I understand that. But there are still tolerances. I very rarely see two Memory ICs with the EXACT same storage size. There are sections of the disk used for error correction that we don't even see in the storage size.
If you are unhappy with my response, that's cool. I won't be responding anymore.
Take care.

You did make better answer now, though. I'm quite stubborn about some issues like this one. Thanks for further details about it.
Hi!
Having dug my old Google Nexus 7 2012 out of storage and found it both working and happy in terms of battery lifetime I let my mind wander towards fixing what I consider the main flaw with the device: Its 1 GB of system RAM.
Now, I have my fair share of microsoldering and idle work in BGA soldering and the like but my software hardware is far more lacking. I already know that the Nexus I have holds 4 x Hynix 2Gb HTC2G83CFR DDR3L RAM and the datasheets for it these are fortunately available, I also know that the Tegra T30L chipset supports up to 2GB of RAM. The closest I've been able to scrape together sofar are Hynix 4Gb H5TC4G43MFR but these use 78ball FBGA and 96ball FBGA, but atleast I'm on the right track in finding older chips...
This is where I run into the software knowledge lack; Simply finding fitting chips to replace the old ones and successfully soldering those on will not neccesarily just work out of the box? Depending on the kernel it might detect and make use of the new chips but it might also not.
Am I right in assuming that there will be a need for software side hacking to accomodate the upgrade?
On a sidenote I also found Daniel Sauvageau's musings on doing the exact same thing back in 2016 but there are no follow-ups to it. He does raise a concerning potential roadblock in his article on the matter:
"Find out, preferably in a non-destructive way, whether A15 is actually routed from the SoC to the DRAM BGAs. Without A15, I would need DDR3L DRAM that has 2KB pages instead of the typical 1KB ones found in all eight-bit-wide chips I have looked at. If neither are possible, then this idea is as good as dead"

Any thoughts, ideas or inputs are welcome!
(Yes, I am aware that this is neither particularly economical nor for the faint of heart lacking a decent way to reball BGA)
Good evening.
Was looking at my Shield Pro 2019 sitting on the shelf, and an idea popped into my head; would it be possible to upgrade RAM and eMMC chips? I have no particular reason for this, besides pure curiosity.
I've got access to professional solder equipment, including rework stations capable of desoldering BGAs, xray equipment to inspect said BGAs and about 20 years of experience with soldering and reworking complex circuitry.
If I'm not mistaken, RAM chips are either Micron, Samsung or SK Hynix and the eMMC chip would also likely be supplied by either Micron or SanDisk.
So, disregarding the physical job desoldering/resoldering chips, are there any software issues that must be taken into account?
The eMMC would of course need to be flashed and repartitioned if upgraded to a larger size, but would the RAM chips require any software modifications after swapping them out or would the system simply accept a larger RAM size out of the box?
I've Googled a bit, but couldn't find any concrete information on what changes would be required on the SW/FW side of this.
Best regards, Tim
Unfortunately, this looks like one of those things where ripping it apart and doing the do would be the way to go. Maybe the least "invasive" thing to do would be a RAM upgrade, provided compatible chips of higher capacity are available. Theoretically you wouldn't need to touch anything on the OS side for a bump in RAM capacity. I think the Tegra X1 supports a maximum of 4GB of RAM and the X1+ supports 8GB - allegedly. I suppose the memory controller is built into the SoC itself so there's no tampering with that.
I don't know anyone crazy enough to do that for me... nor am I really willing to apply my very amateur BGA soldering skills on a device like this one.

Both was already done on Nintendo switch (also tegra X1/X1+)
Emmc is the easy part, ram is possible but you need to know which ram are supported.
