Upgrade to larger ROM chip? - JAM, MDA Compact, S100 General

Has anyone looked into replacing the ROM chip (flash memory) in their magician (or any unit for that matter) with another one of higher capacity? This would be particularly useful if WM5.0 works its way onto the magician, as it uses ROM to store programs and data rather than RAM.
I know this would involce intricate soldering, but if RAM can be upgraded, surely the ROM can too.

You can not upgarde ROM chip becouse it in CPU

bull****.
do you even know what SoC, and CPU are?
RAM is on SoC, CPU has only cache memory -.-

Are you trying to say that these devices hav SoC, hence the ROM cannot be upgraded?

I was trying to say hence these devices have SoC, memory SHOULD be upgradeable, because
cache memory is not what is the point, it's NAND or RAM, depending on the case.

Has anyone been successful in doing so?

What on Earth is the Leo going to do with 128MB of dedicated video RAM?

See subject line.
I need to admit, its a lot.
But, i wonder how the memory is being shared. The HD2 has 428MB of total Ram.
But 128MB is being used by the GPU. The question is, is the 428MB ram, really global ram. Or is the 128MB ram dedicated ram for the GPU ( like the 2700g has 16MB dedicated ram ).
If its global ram, then maybe its possible to reduce the ram amount to 64MB or 32MB, and use the rest for programs... So many open question, so little information about the snapdragon's design
For instance, the Toshiba TG01 & Asus F1, both have 256MB global ram. But does that mean that both companies did not report the 128MB "extra" ram, in there total like HTC does. Or does it mean, that they use a smaller part off the 256MB ram, for its GPU.
i'm hoping that its going to be in preperation for what comes with Winmo 7, perhaps gaming, maybe MS requires such a high amount of vram as a standard?
Doesn't it have 448MB? 320+128?

Yes, you are right. My bad. It's indeed 448MB.
Yeah. 448MB = 128MB dedicated video memory, plus 320MB conventional memory.
I suspect other vendors probably simply don't advertise video memory; it's also possible, of course, that they have a unified memory architecture (e.g. that the TG01 and Acer F1 use their main 256MB of regular memory to store video in); that might account for the Leo's 3D graphics benchmark scores exceeding those of the TG01.
Had been the same with the Xperia X1, there where also rumors that it does have (maybe has, don't know how to chekc this) 128 MB dedicated Video RAM. Don't care to much about it. It'll be fast enough anyway!

Is it even confirmed that 128 MB is indeed for VRAM, or is it just speculations so far (even though I'm inclined to think the same)?

Core requirements:
Processor: ARM v6+, L2 Cache, VFP, Open GL ES 2.0 graphics HW (QCOM 8k, Nvidia “Tegra” AP15/16* and TI 3430 all meet spec)
From that single post it states that WM7 needs a Tegra graphics chip... but from the release QCOM 8k also meets the requirements, and the Leo will have Snapdragon QSD8250 1 GHz processor..
Am I missing something?? it seems it should be upgradable to WM7.

According to B3ler3fonte who gave us details about the Leo in the general thread (here: http://forum.xda-developers.com/showthread.php?t=560143&page=48) it will be compatible with winmo 7.
In order to save some answers, I am posting you a far more detailed specs of Leo, so, as u can clearly see from the specs, u’ll notice (and I think it was a question which was circulating from loads around this thread, of whether future WM7 will or will not be supported by Leo) that it will be absolutely supported. I think we should all celebrate!!

Qualcomm 8k = Snapdragon's QSD8xxx-series chips = Qualcomm Snapdragon QSD8250 (which is in the Leo).. so the processor should meet WM7 chassis 1 requirement.

Thanks Why_999 I wasn't aware that the snapdragon was Qualcomm 8k series processor.
i think it should be reserved memory actually for some sense UI things and similar stuffs . not dedicated video RAM
Isnt 128 too much just for clouds? There are 3 variants possible:
- someone was speculating with specs in his blog and the rumor broke out;
- thats for gaming purposes( see wm7);
- thats for iphone graphics emulator)))
RAM is split between ARM cores, general-purpose ARM11 and radio ARM9. Portions can be reserved for other purposes (video acceleration for one) too. Chances are there's ~256Mb of RAM accessible from OS on HD2, which is fairly reasonable, IMO. More RAM means less battery life...
It's "just" to have the 1Go needed for WinMo7... I am sure our cookers will change this to get the best of this awesome phone

GPU power of 32A Question!

So I was wondering if there is any hack that would add more ram to the GPU, comparing to RAM hack that takes GPU RAM and gives it to Phones RAM, Could it be done vice-versa, so take ram from Phone RAM and giving it to GPU, could it be done? and would it increase GPU processing power?
i too was wondering this too because im a heavy gamer
I'm just assuming but, the RAM pool is all the same RAM chips. It's just being managed and distributed between the GPU and CPU by software.
But I'm not sure.

Upgrade RAM?

Hello! Is it possible to replace and upgrade your phone's RAM and solder aftermarket RAM in it?
Thanks!
ps. Sorry for bad English
I do not think you can, these phones aren't really made for upgrades.
I have heard mention of this before ... but the compact design of the phone and the ability to find (upgraded) ram that would work with the chipset (soldered or otherwise) seems nearly impossible to find to me.
However, if someone was successful in this I would certainly be interested in hearing how.
I think it is too hard or You cant ('x ' )
Seeing as how the RAM modules built into the phone mother board are BGAs (ball grid arrays) it is nearly impossible to replace them without highly specialized equiptment like a FineTech BGA rework machine and the proper heat profiles for the given parts. That said you are more than welcome to try some methods that are not proven but seem very funny to me. I believe there is a youtube video of a man desoldering a BGA using an oven.
Needless to say of you dont like the amount of RAM your device has you may just have to wait until you can get another device.
In especial cases you can UNLOCK the RAM, but it didn't happen as a lot of devs tried and a really small quantity(of devs not phones) reached this point and the only phone that I know is unlockable is the ZTE Blade.
As an embedded system with some [normally] tightly controlled schematics and firmware, this would be unlikely for you to acomplish, since you're asking the question to begin with.

Not at all related to this, blade had 512mb of RAM in it, but it wasn't accessible- solved by a kernel change
Sent from my fingerz 2 ur eyez
.
all smartphone devices have x amount of ram. say if you have 1gb ram in your phone you might only be able to use 868mb of it . it is becous your phone uses 128 mb for your gpu. it is plausible to make some of your gpu ram available as regular ram and that is done with an kernel mod. for my phone(lg optimus) 2x it is called a ram hack. it always comes with some faults depending on how much you take from the gpu. i have a 32mb shared ram hack so i cant reboot just have to turn the phone on and off
hey all
I guess it would be possible, however it might not so easy, I upgraded the ram of a wrt router some time ago: http://neophob.com/2006/01/wrt54g-ram-upgrade/
There's no chance of upgrading a mobile phone RAM .
I think the same,no way to upgrade ram on mobile phone
This is possible, but as others have said the complexity and difficulty to desolder a BGA ram chip and then put a new one on perfectly without messing anything up is incredibly high. And in addition, you have to find a ram chip that is compatible with your device (pin count and configuration, physical size, voltage, timings) and of a higher density, another difficult feat. So while it is technically possible, the practical answer is no it is not possible for anyone to do in the real world.
Hmm dont think you can.

ive seen it done, it can be done. its just really hard and nerve racking
Man bga chips are pain in a$$, unless u have sophisticated workstation.
A single short circuit/ loose contact can blow up ur entire CPU/motherboard.
Sent from my HTC HD2 using xda premium
Hate to say it but no, in many of the SoC (System on a Chip) devices, the RAM is a soldered component of the main board. They are using RAM Modules rather then SODIMM Chips. It would be nice though
Parts
Anyone have any ideas of where you could even start to look for ram that would work? I have a HTC Evo 4G. I wonder if its possible to find parts from a HTC Evo 3D and modify.
seems so
just from the CoE course, revers engng and tweaking hardware is a good start
it's possible, but if you think you'll save money that way, you're wrong.

S7 Edge real Ram/Storage size?

Hi
just ran CpuZ on my Exynos model and it indicates:
Total Ram 3580MB (1190 available at the time of the test)
Internal storage 24.86GB
I know about the 1000 vs 1024 story, but even with that in mind, those figures look quiet far from the numbers announced (4GB & 32GB) by Samsung???

I'd also like an explanation. I've no doubt there are 4gb of memory soldered onto the motherboard, but I'd like to know why only 3.5gb are reported available.
In 32-bit days, before Lollipop and ArmV8 architecture, devices always reported a maximum of 3.5gb available because that was all that could be used on a 32-bit system. I'm wondering if this ram reporting issue is due to some kind of 32-bit limitation on our 64-bit devices.
If anyone really knows the technical reasons for this, I'd like to understand what's going on, just to satisfy my curiosity.

Is some of the RAM reserved for the graphics chip, like a PC has system RAM and video RAM for the GPU?
Some of the RAM around 512mb is allocated to the GPU, and for the storage, 8gb is used for android system partition

is it possible to expand RAM by changing higher RAM chip?

My K1 has upgraded to 7.0. it became slow when i use it. I rooted and optimzed it but it can olny get a lttle better.
I want to know if an android device can expand RAM by changing the RAM chip? And if it can perform much better?
its very difficult and not very cost-effective to hire skilled engineer to replace it . just buy a new tablet

so can u tell me will its RAM expand if i change the RAM chip withe higher one?
i saw the RAM of xiaomi tablet2 can be expanded with doing that. so can its CPU.

1st,thank you for replying me. i did a lot of things befroe i buy it, because it is a second hand.and it former owner told me it was upgraded to 7.0 and became slow maybe because it 2GB RAM. so i was thinking if its RAM can be expanded by doing so.
Likely not, you will need a compatible ram chip. Even if the larger chip is compatible, the board or kernel may limit it to just 2gb. 32bit devices cannot use more than 4gb anyways. The best you can do is to just increase the swap.

I have been having the same thoughts as you. On this device, the ram is actually not built in the soc as most smartphones and tablets, its it separate from it on 4x512mb chips.
I got the tablet recently and the first thing that came across my mind was changing the thermal paste, the factory one is really garbage so I cleaned and replaced it with arctic mx2, under the heatsink of the soc and the ram there is some sort of a graphite thermal pad, which is not very efficient, I replaced it with thermal paste as well. Unfortunately I didn't take any pictures, so idk what are the ram chips exactly, devcheck reports that the device has lpddr3 1066mhz ram but I'm not sure if that is trustworthy.
IMO upgrading the ram to at least 3gb is very possible, now the question is what kind of ram chips we need and where should we look for them.
Tegra K1 is practically the fastest 32-bit soc in existence, so more ram would definitely help it out a lot. I mentioned it in another post but on the latest firmware the ram usage is abnormally high on this device, sitting at about 1gb at idle(no gapps, LOS) while it should be closer to 500mb.
