Anyone capable of doing such upgrade??? guys Mogul needs a memory boost to be an ultimate device. it must be possible to preform a Ram upgrade lets brain storm this and make a step by stem mod chip like mod or even some one could start a service perhaps.

Someone with intimate knowledge of the memory map and microcode for the Qualcomm processor inside. This person would have to determine if there is sufficent address space above or below the existing RAM and impliment it in a new firmware flash. I am wondering myself if the reason for the small RAM might be that there is or was no address range available for it, or just maybe short sighted designer decided that this was all that would be needed. If the latter is true then it would be possible. Lastly I would mention that a really good station and tech would be required to change out the RAM for a larger chip, assumeing that one existed in the same package. Might have better luck doing a RAM based add to the microSD slot by adding to a custom engineered card. If someone did that then the applications could be mapped to addresses that already exist and are known. You would end up with a microSD card with maybe 4 gigs of flash and a few gigs of RAM ??????? That might be easier. Food for thought.

Hello, as we know, Galaxy S1 was advertised with 512MB ram, but in real there was only ~340MB of usable RAM! So i want to ask, how much ram is usable for applications and how much is free after fresh boot? Can someone check this? You can see this informations in task manager.
I think its about 800-850 RAM.
The original SGS had 512mb of ram as advertised. For some reason people assume that their phone behaves different than their computer. The operating system and everything like that needs to use the ram as well.
AS stated though I understand the SGS2 to have approximately 850MB of ram free after running the OS etc.
If I continually hit advanced task killer it will give me about 445MB free. In the standard task manager it says /833MB.
I don't really think this is all too relevant. You will never have anywhere near the maximum amount available just as you won't in a modern PC either and with phone OS's getting more power hungry and complex this is unlikely to change.
If the amount of ram bothers you check the video of the guy doing heavy multitasking on the phone and that will clear your mind.

Thank you for usefull information. I'm just interested in real numbers, because HTC phones have all advertised ram available to system, instead of samsung, which is cheating about this. Yes the OS is using ram... but from 833MB, not from 1gig. How can system use ram which is not visible to system? Android is linux, you can easily see how much ram is available and usable for system... it's 833 not 1gig. I believe that there is 1GB ram chip, but some memory is dedicated to other components. However 833 MB is really enough for mobile phone.

It did have 512MB of ram in hardware, but a pretty big part of the 512mb was actually dedicated video memory for 3d and movies. The Galaxy Tab 7" which was advertised with 512MB actually had ~600MB of ram in hardware, with extra ram outside the 512MB being for the dedicated video.
With the SGS2 it seems to be as the original SGS with dedicated video ram being taken out of the 1GB. It's easy enough to check by looking at the kernel config files. (And you can even tweak the numbers a bit to get a bit more free ram, as was done in the SGS)
Hope we're not heading down the old line of trying to run with loads of free RAM... I'm of the philosophy that if you have the RAM available, you should use it, rather than have to load things up from storage due to removing it to make a number bigger on a task manager...

Your philosophy is absolutely correct. In Windows that might be a good thing, because it starts buffering to the HD when you run out. But Android will just close some background processes automatically to clear ram as needed.

Unfortunately people these days only know about ram management from that poor excuse of an OS called Windows.... excluding 7.

Agreed, as long as there is a big line between FREE RAM and TOTAL RAM. More total RAM is always a very very good thing regardless of how good the ram management is.
This thread is about total RAM available to Linux/Android, so it's good imho.

Xoom got 1GB of memory, but, 256MB for dalvik vm, 256MB for GPU, 512MB for apps)
So, now with 4 cores, 512MB for apps will be enough?
Or maybe ASUS will be more generous and will give us a full 1GB memory for apps, without dalvik ou GPU?
I don't own a asus transformer (old version), I don't know how tegra 3 will work too. So I really don't know.
Anyone have a clue about it?

Interesting question, I heared that multitasking with 512 MB of RAM isn't very good because apps close very soon due the lack of memory.
When Windows 95 shipped, a typical PC had 8MB of RAM, and now this tablet has 125 times that much.
I'm guessing the nature of Android requires less RAM that a desktop OS:

I know a tablet require less memory, they should at least...
But if we got more ram, more complex applications/games can be developed!
We have now some restriction about compress/uncompress files because of the amount of ram free/avaliable at the device.
Let's wait some one put their hands at the tablet and say to us

Every Android device is like this: some RAM is used by the system, some RAM is used by the video frame buffer, and some RAM is used for applications. Every time a new device is released, this forum and others are filled with complaints like "I don't have 1GB RAM!!! ASUS screwed me!!!" The fact is that there IS 1GB of RAM, it's just being actually USED as it's supposed to be. And, if we had only 512MB of RAM, then far less would be available for running applications.
Furthermore, the number of cores has nothing to do with this--it's not like there's a linear relationship where more cores equals the ability to run more apps. Or, that we're somehow going to be crippled vs. a device with a dual-core processor. We'll be able to run the same number of apps as any other 1GB device, only more efficiently and quickly.
It would be nice to have 2GB, of course, but then the device would just be more expensive.
Plus honeycomb and Especially Ice Cream Sandwich do a great job of memory management. You could always root n use some app to freeze some apps/system processes you don't need or use to free up ram. I think using those free ram apps does more harm than good with later dated android OS versions. Of course more RAM would be ideal but 1GB is good enough for the prime. There is nothing or any type of apps or games out now for any tablet that truly demands more of that. People don't need that much multitasking going on to have a million things running in background. All that'll do is burn up the battery..lol

I think if will be the same number of memory modules, don't have any relationship with battery time.
Some websites eat so much ram and processing (bad developed sites), so, I think the navigation will be more smoother if we get more RAM.
Anyway, I'm thinking in buy one too, but, maybe I will wait for a version with 2GB.

The RAM in this tablet is hell of a lot faster than the previous TF101. Along with the faster GPU, and CPU, this thing should multitask a lot better than previous dual-core tablets.

You are right about websites. Web browsers n sites can eat up RAM fast as he'll. More tabs open, more ram eaten up. SH!?, my iPad only has 256MB RAM total and I make due with it..lol browser shuts down at times due to too much ram used or too many tabs open. Heavy duty games will eat it up also.

Yep, the Prime has a faster/more advanced memory module or something. Plus several vids showed it multitasking like crazy. Andyx, member here, even showed a vid with his prime loaded with widgets on all home screens and stuff running in background. It still moved fast n smoothly between pages in such. No slowdown at all.
I multitask on first Transformer and had an app restart in the middle of it maybe one time - when sth was clogging the system (a broken game or sth). Browsers can be a problem though, the more memory they have, the happier (faster) they are. Games use a lot of graphic memory, so the more of it, the better (256 for 2D games is more than enough, but for 3D games nothing is enough ).

1GB RAM was not enough for me on original Transformer.
On SGS2, I usually get around 500MB of free RAM and that feels sufficient for me.
But on Original TF, with 730ish visible/350ish free, together with more sophisticated apps, RAM easily runs out... The browser will be killed as soon as leaving it.

iOS is not as memory thirsty as Android... Not sure about the mechanism behind but that's what happens. The newer tablets after TF201 will probably pack 2GB of RAM.

I believe I heard Samsung and Lenovo new line of tablets coming out near future will pack 2GB of RAM. I wish at least the memory could be upgraded as easily in tablets as with PC. Imagine packing 6-8GB of RAM into Prime
dont forget, more ram means also more battery drain. Ram sucks quite alot.
Of course more is always better^^ But i think "only" 1gb wont be a bottleneck for the prime.

Yes you heard correct.I posted the link a few threads back.The Lenovo tablet itself will have 2gb of ddr3 ram.Which is a faster ram than the ddr2 ram in the Prime.But I also hear the Lenovo tablet will be a lot thicker (yuck lol).No telling how much ram Samsung will have to put in their 11.6 inch screen (2500x1600) ..that screen is going to be a battery/ram eater lol.
The Lenovo tab is making me doubt getting the Prime as if all the ICS tabs that were made for it feature 2GB RAM then it must mean ICS will benefit from it.
Granted its not as thin as the Prime and wont have a keyboard but prerformace will be better.
As far as the Samsung ICS tab..that will be EXPENSIVE because of the screen, I expect it to be around £599 as currently high res screens that size are in small yields.
I have a HTC Sensation which has "768 MB" of RAM, but a lot of it is used in normal use. I mean a LOT. I normally only have about 100 MB of free RAM. This is how essentially all Android devices are.
Yea, there are going to be some tablets coming out partway through 2012 with 2 GB of RAM, but quite frankly Lenovo products don't do anything for me because they're typically so ugly, and I'm not interested in a Samsung tablet if they put Touchwiz on it.
While I would like 2 GB of RAM, you have to consider that the TF Prime is IMO ushering the beginning of the 2nd generation of Android tablets. No company so far has put such an effort into an Android tablet. Look at the Motorola Droid XyBoard, Motorola's successor to the Xoom. It's absolutely pathetic compared to the TF Prime. Until the TF Prime, every tablet maker so far has been half-assing Android tablets, giving them basically the same specs as always. The TF Prime brings in the true beginning of 2nd gen specs, and it still comes in cheaper than the half-assed XyBoard. Considering that, I'm not surprised that Asus can't make absolutely every spec on the TF Prime amazing. They have to make money on it somehow lol.
I don't think a "super resolution" will be good for us.
Ok, Tegra 3 is X times faster than Tegra 2, but my Xoom got a 1280x800 screen.
Now, 2500x1600? holy ****! too many pixels to handle...
Lenovo? don't have a keyboard.
Samsung? don't like they software modifications...
A asus "prime 2" with 2gb and a faster ddr3? I will got one
Let's wait and see what the future has to offer.
Sorry for the noobish question, but this has been confusing me for a while.
What slows down Android?
My Xperia S tablet and my One X periodically slow down. The tablet more so than the phone.
I am uncertain of the relationship between processor speed, RAM and storage on the Android system and do not know how much is enough and what is poor.
Does the processor just get jammed up and ends up queuing tasks to do on storage? How much storage space is minimal to keep the system ticking along nicely? Does lots of available RAM matter given the average of 2GB on these units is all one gets?
How much difference in RAM usage between 720p & 1080p display? Z5c RAM way too low?
I've read several times, that a 720p display uses less RAM than a 1080p, plus the Z5c has a couple of extra features, like 500MB of ZRAM, which should make multitasking quite good and not a thing to worry about, despite the low RAM.
But here's the thing: Can anybody tell me, how much exactly is the difference in RAM usage between 720p and 1080p? I was never able to find hard numbers. Is it 50% because of half the resolution? Is it like 5% only or something else? Or is it flexible, depending on the apps? Or, if it's a fixed amount of megabytes, how much is it?
I'd love to get the Z5c due to the smaller size and it is about 100€ less than the Z5, but I'm also a heavy user and struggling very much with only 2GB of RAM in my current Z1.
I have at least 10 different apps running in the background all the time, like weather widget, several messengers, xposed, data counter, greenify, etc.
Plus, I usually like to open a lot of tabs in the browser, 10+ is quite often and my browser either craps out completely and closes itself or the tabs have to reload all the time, this even happens with only 2-3 tabs.
Same with apps.
They are almost always reloading, most of the time I can't even visit my "friends" in Simpsons Tapped out because the game crashes when I try to visit their cities or it crashes in my own town because it is too large.
The music player stops working during browsing or one of my running apps closes itself due to lack of RAM.
Is this normal, is the RAM really too low or am I just expecting too much from smartphones? I treat them like small computers, like the ads suggests. I guess, they are just too unrealistic.
The ONLY thing keeping me from going for the Z5c is the low RAM and this would be the only reason for the Z5.
Also, 2GB RAM is a 2012 standard, it's now 3 years old. After a usual usage time frame of the Z5c of 2 years, it's 5 years behind. I simply can't seem to get myself to buy an already outdated device in terms of RAM. For me, 4GB would be very welcomed.
Can anybody answer my questions regarding RAM usage or someone with a similar heavy use case can relate their experiences with the Z5c and RAM problems?
The RAM is more than sufficient. I have been using this phone for some time now and I can keep any number of apps open in the background and they do not close.
---------- Post added at 05:38 PM ---------- Previous post was at 05:37 PM ----------
When I say "any number" I mean any number of apps that I need to keep running in the background. I've never run out of RAM on this phone. Whereas I see a lot of phones struggling with multitasking
I don't just mean many many foreground apps which I have started myself and switching between them, but also like 10+ apps which are running as soon as the phone has finished booting and which I want to run in the background all the time, without counting additional apps which I open on purpose. Apps always running are: Hangouts, facebook messenger, Whatsapp, weather widget, one handed mode, 3G Watchdog, onavo extend, proximity screen off, greenify, setcpu, automate it, afwall+, twilight. A total of 13 background apps plus many foreground apps. After everything has loaded after boot, I'm already down to 700MB free RAM, without any other open apps.
When RAM reaches 500 or below, the force closure starts.
How much is your available RAM after boot and with many apps running?
i don't know if you are aware of it, but xposed module "app settings" has an option to keep chosen apps persistent in memory. I cannot assure it works, but probably it does. You could enable it on the apps you need to be kept open and then fill your memory fully, then see if Android system kills other apps (camera, gallery,...) instead of your favourite ones. This might be a workaround for you, or might not: if you open lots of tabs on your browser, Android kills other apps, while Windows would become sluggish but keep everything open and use the swap file. Regarding the swap theme, Android has the Zram function, a kind of swap file in the ram, that compresses some RAM in the RAM itself (at the cost of some CPU power). This might also be useful but don't know if it is already supported by stock xperia firmware or it must be implemented in a custom kernel.
Well, available RAM really doesn't matter much. Lollipop especially is designed to take up as much RAM as possible. That makes the operations smooth and the processes run in the background. But I'll attach this here. I never clear the tasks and I always keep them running so I will have less RAM. But my apps don't close on me though
It seems 2GB ram doing fine on my Z5c, I guess because of it comes with ZRAM enabled in stock kernel(for the cost of cpu and battery). Yes, 720P spend much smaller amount of memory and cpu compared to FHD/2K. There are many reports confirmed on Z1/Z2/Z3/S6 board when people used resolution changer and found much more free ram available, you can try QHD 960x540 if you want even more free ram.
I got 1GB free ram after boot up and same with my S6 but since my S6 running 2K resolution with poor Samsung memory management, actually the Z5c performs better when deal with the killing apps problem. If you will use greenify donate ver to freeze all bloatware I think memory is good, the android 6.0 seems to have better memory and battery life as well.
Can you tell me more about the resolution changer? Is it dangerous and can lead to a bootloop or not booting at all?
Z have 2gb of ram and 1080p display and have no ram issue..

I don't use it on my S6. It won't bootloop or not booting but just some stock apps will have menu problem bcoz they are hard coded for native resolution, you may need to decompile those apks and edit some .xml files manually to modify the default resolution to make it works.
even my XZU with 2GB of RAM and 1080FHD is still perfectly able to multitask. no need to panic for such 2GB of RAM. yet. :fingers-crossed: well maybe when there's a game with big memory requirement in 2-3years time then you'll need more than 2GB but i bet it's not a game worth playing coz it's not mobile optimized and the devs are too lazy to optimize.
Default set at 507MB ZRAM, you can increase it to 1024MB if you wish
Yes, but only with root? And then you lose the warranty, camera functions, miracast and such because you need to unlock the bootloader.
A root exploit without bl unlock, like on my Z1, is what I'm hoping for. I also don't understand why manufacturers don't implement to gain root access via a simple reboot. Make the option available, display maybe 2-3 warnings and info screens before, then if you click yes, a reboot happens and you're rooted. Easy as this. No features lost, no exploits necessary which take forever to arrive, if at all, and involve downgrading and such. I think one manufacturer enables exactly this.
It would be unthinkable on a Windows or Linux system if there wouldn't be the option to work with full admin rights...so why is it the norm on Android and nobody bats an eye?!
Btw: I've tried the resolution changer and changed the resolution to 720p. Although this should have decreased the RAM usage, it actually increased it by around 100MB. How is that even possible?

I think you answered your own question here. If you need a whole lot of RAM, you should probably look somewhere else.
yes, it needs root and you loss warranty and DRM and such stuffs.
Linux like to cache things, if u got more free ram it might just cached even more. It won't used more 100MB ram in reality.
The thing here is the Android 64-bits.
1080p device with 2GB RAM in Lollipop 32 bit = more than 1000MB of free RAM (average).
720p device with 2GB RAM (and zRAM) in Lollipop 64 bit = more than 550MB of free RAM (average).
Now, the resolution mostly affect the used RAM when gaming, there is not a big difference outside games.

I have never seen free memory more than 1GB of RAM with my XZU. Right now it hovers around 600MB of RAM.
for gaming it is not an 'always' case so memory cleaning at the end should happened only 1% of the time you use the phone.
Who cares about how much free ram there is? The ram is meant to be used and Android is made to use the RAM for caching and so on.
Talk instead about how well it runs in practice.
Anyone that has experienced any problems that could be because of the device only having 2GB of ram? Let us know.
If not, then I guess the fact that the Z5C "only" have 2GB ram is not a problem...(?)
Here,me! I'm having a lot of problems because of low RAM and the whole purpose of this thread is to find out if the Z5c with its 720p display and zram and such makes a huge difference in RAM performance, if at all compared to my Z1 with also 2GB which is always reloading tabs, crashing games and apps, force closing apps due to lack of RAM, redrawing the home screen when exiting apps and so on.
If there's no big difference, then devices with only 2GB are not for me.
It's good that Android uses all the RAM for caching, but I strongly believe that in my case there is simply not enough RAM and that's why all my problems occur.
And also Z5c uses LPDDR4 RAM if I am not mistaken. So that's actually more efficient. Well I have faced ZERO problems with multitasking. But I dunno about you
