[Q] A500 - how much RAM in reality ? - Acer Iconia A500

Hello,
After testing some task manager application to try to see what process are running ( my tablet is losing a lot of battery quickly, under speedlight 4.3) ,
I Saw in their infos panel that my Tablet is really a A500, but it has only 743 GB of Ram instead of 1GB announced in all advertising.
i saw lit on several app, son I believe lit ils reliable.
Someone knows why ?
Is it a bad news for me ( something wrong on my device?)
Thank you for any info

Also some of the RAM you can never use as is it used by the OS, hence why you don't see the full 1gb. Nothing is wrong with your device.

There's 1GB of RAM, 256MB of which is reserved for the GPU.

Available RAM info

Hey guys,
I was watching a demo of this phone from the French blog Frandroid and came across some useful info about the available amount of RAM:
We know the Galaxy S has 512MB of RAM, however, being the owner of an i8000 Omnia II (only 256MB), I can tell you that there are major issues with the very low available amount of RAM the phone actually had (the people over at Modaco were fighting like crazy to bring the amount up).
- Apparently, the phone has 180MB of available RAM (the rest seems to be used by Samsung/Android and not available for apps and all that).
- The phone has 79MB of available RAM with the following apps running:
+ Email
+ Clock
+ Amazon MP3
+ Voice Recognition (from Google)
+ Browser (however I don't know if it's Web or not)
+ Social Hub
+ Video Player
+ MP3 Player
+ "Advance Task Killer Free"
I hope this helps.
Cheers,
Will

That looks pretty good to me. (I can't see what other apps i would be using with all of those running. To use GPS or read ebooks or write documents, etc I would close half of them)
Does anyone know if froyo uses more resources than eclair?
PS. I assume you mean those apps were all running simultaneously, and there was still 79MB free?
PPS. This will be my first android phone, so I hope 79MB free is pretty good. For some reason I seem to think that your post is criticizing these results, but I could be mis-reading. It is so late...
Because they are using the prototype version.
As gsmarena have stated the prototype version does only have 256 Mb while the final version will have 512 Mb

No, the prototype had 512 meg of ram, just the software wasn't reporting it correctly
There are two things to consider here: first, with 2.1, the system can't use all of the available RAM. That will have to wait until Froyo arrives. Second, Android isn't Windows! Its Multitasking is very advanced and specifically designed for mobile devices. Even if you think all these applications are currently running, and the device does its magic to let it appear so, they don't always eat their share of RAM.
Free RAM says nothing at all on Android. Even apps that aren't currently "running" are kept in Memory when they are likely to be started again soon. What use is a large sum of unused memory? If you really need it, it will be there - at other times be glad it is put to use!
That might be true but as an i8000 owner I strongly advice everybody who want to buy that phone to what still somebody realiable got the phone and can report about the total amount of ram that is aviable to the system (OS + apps).
The I8000 only has about of 139 - 156 mb ram aviable to the system besides being sold as a 256 mb device.

I think this is why the I800 was fast because "maybe" samsung came up with away to use some of the RAM space to speed up the device .
It might happen again specially while the Galaxy S looks so fast
For now let's say that Galaxy S will have 412 MB of available RAM .. still this looks too much
goood..

Galaxy S Ram and Himem........

Hi all,
I am getting this phone on July 21 when it's avaible through T-mobile. However, I ran across an issue while reading on the vast number of threads about this phone regarding the available memory.
1. Is it true the Android 2.1 is limited to 256mb of ram unless "hi-mem" is installed/enabled by the rom?
2. Is hi-mem enabled on the SGS stock rom? From my reading it doesn't appear that it's properly enabled.
3. If hi-mem isn't enabled, does that mean the SGS is functioning with only 1/2 of it's ram?
4. If so, how much free ram is showing on the stock rom and how much should we see once hi-mem is enabled?
I'm assuming that since many Android phones come with 512mb of ram these days, that hi-mem has been properly enabled on some of them. How much free ram does a typical android phone running 2.1 or 2.2 have after bootup?
I'm currently using a Touch Pro 2 which runs out memory all the time and would rather not have to deal with that on Android as well. I assumed that 512mb is supposedly to be more than enough to run 10+ programs at the same time should I choose to.
Thanks in advance.
It doesn't appear to be using 512MB I only ever have around 100 meg free. I used to have a touch hd and know what you must be thinking but i can assure you even with only 256 available it is fast and hasn't run out of memory on me yet. be sure to download a memory freeing app like task killer.
It runs quake3, something i could never get my hd to do with out practically killing the os
Kernel supports 512M RAM.
with the new Gingerbread specs it REQUIRES 512MB .. now if its 256MB , that's something to worry about

Don't worry, it has 512mb. It's just that some older kernels didn't support more than 256mb of ram, so the phone simply didn't "see" all 512mb.
My concern was that the kernel out of the box was too old to support the full amount.
The phone physically has 512MB of RAM. However, I think Android 2.1 is limiting the availability to 256MB.
Froyo 2.2 will correct this issue.

A little worried on Available RAM

We know the Adreno 330 takes a lot of RAM, it says in this video only 2440mb of ram is available.
That doesn't shock me. What shocks me is after the guys is running the video and in the screen shot it says available ram.
Note 2 610mb available :good:
Note 3 270mb available!!!
Link to video

What do you guys think? Will this be an issue?
My htc one X has more available RAM than that! and its horrible at multitasking :crying:
That's shocking where is all the ram gone looks like little pacman inside the phone has been busy crunching all those megs of ram ouch.
Yep !
Same problem here. I think that we'll need to wait the root for the N3 to clean up trash apps.
No need to worry.
I made a thread about it since I saw a screenshot of CPU-Z stating that were only 14% of free memory.
But I was reassured in the thread I created since I got some details regarding the overall free RAM you can get on boot : http://forum.xda-developers.com/showpost.php?p=45750359&postcount=19
So you can expect, straight out of the box, an average of 1Gb of Free RAM to play with at your leisure !
There's already a thread on it and all things related to ram was covered so no need to continue this again.
No need to worried. I am the user of Note 3, didn't face any RAM not enough yet since purchase start use yesterday.
I myself just tried out a note 3 in a Samsung Mobile Store and it has about 1Gb of free RAM after clearing the memory. If you let the phone run without doing anything you just loose 200Mb.
Plus Android's VM ans the launcher take 400mb!

[Q] any way to retrieve back the 1Gb RAM from GPU allocation?

Hello, I noticed that, from 4.1 to 4.3, ram dropped twice.
Now it's just a bit more than 1GB.
Well, I bought a device with 2GB RAM. I know, that's not completely wasted but allocated for GPU.
But... 1GB? On 4.1 we had 1.6 GB of real free ram, then 1.3 on 4.2, now 1.1!
And on kit kat? Maybe 512 MB?
Anyway. There is any way to get it back? Custom kernel? Custom ROM? No one tried this? I never compiled a ROM or kernel for android, so I have no idea where to start.
I think that's not an honest way of upgrading. 2GB was high end, and in android world would have been a lot of ram for a lot of time. 1Gb is just barely enough... It's already killing application, usually launcher or keyboard.

There is lots of information out on the internet for this very topic. I believe it has to do with more memory allocation set aside for GPU or processing.

I know the theory, I don't care why they did that.
It's like selling it for 2GB, then getting 1GB back, then... It's a 1GB tablet!
They should put 1GB for GPU and 2GB for RAM. You know, RAM, Random allocation memory, something that should be accessible from every application, not just locked there waiting for the GPU.
320, even 512 could be acceptable as a sacrifice for GPU allocation.
On PC you can even allocate 64MB on Intel chipset for GPU... And on PC you can have a lot of spare memory.
And on a tablet...One of the most powerful, and what should have been a top-sell for Google, you reserve a gig for GPU?
That's crazy. I almost feel scammed.
On topic:
Yeah, ok, but... If I'm not going to play. Can I flash a different kernel with some different init script?
I think that's something kernel-level. I didn't even rooted my Nexus 10, so I have not a lot of information, but it's not a common thing for tablet > 1920x1080 to allocate a gig for GPU. That's not right... I feel robbed this way.
I also feel the same way. On the nexus s forums there is a mod for kernels called bigmem, which takes some ram from some of the components and make it available to the system, for apps. I think the 1st ones who did this are the cyanogenmod team themselves, in one of their roms.
A kernel dev could do some mods to give more RAM to the user instead of reserving it, lots of phones have kernels like this. Also things can be removed from the ROM to free up more RAM to the user instead of it being taken by system services. I think this is also a lot of the reason we have less free now with Android OS version upgrades, because Google is adding a lot more services and these services take memory. We used to have 512MB of memory reserved for GPU, this was increased to 768MB in 4.2.2. I havent looked at the changelogs for 4.3 on this tablet but I dont think the GPU specifically got more reserved. That other 256MB lost over these couple version looks to do more with system services than GPU reservation.
That is my interest. Is anything available? I don't play a lot.
On an Android device, memory means future proof. Not totally, but a big part plays there IMHO .
1Gb is becoming low end, my galaxy nexus swap a lot if I don't remember to swipe away some application from the application preview button. And my galaxy nexus have 1gb - something like 230 MB allocated = almost 750 mb free. Not too far from 1100 MB free.
It will take a few application update, newer g+, Facebook, Google music and chrome et voila... You launcher will have to restart every time loading your 80 application, and the app will lose data swapping between applications (meaning that it was killed to reserve memory). It' s already happening and it' s sad, since it's a high end device.

I do not think anything is available now, everyone seems to be concentrating on adding features and functionality than slimming down and freeing memory. An example of what can be done is if you look in the GNex section of development there is a guy named mpokwsths with his "Mpokang kernel" that is removing things and slimming down the kernel to give more free RAM. I believe his thread says he is up at 772MB free on the GNexus now at boot. But no I dont think there is anything yet for the Nexus 10

The rumor is that KitKat will be optimized to run on low-memory devices down to 512 MB (the article mentions android 5.0 Key Lime Pie, but it's likely that's what's being released as KitKat instead) when it comes out in a month, again according to the latest rumors. Presumably it will run a lot better on the Nexus 10, but we'll have to wait and see. At least we'll get it within a week or two of release, :highfive: as opposed to the many months most non-Nexus owners have to wait.

[Q] RAM missing?

Hi
I´m kind of new here but still haven´t found an answer why my Nexus only shows 1097 RAM instad of 2000? Even tried different hardware checker and they all tell me the same. Have I made I bad flash?

The 2GB ram on the device must accommodate both the operating system and graphics Ram before any apps are loaded. So what you see is normal. This is no different for laptops. Also the 16 or 32 GB internal storage shows less after formatting and Android OS plus Google apps (Gapps) are installed. At least with the Nexus 10 you have much less bloatware compared to other Tablets (eg. Samsung).

Thanks for you answer 3Dsammy.
I understand that you use RAM when things are installed, But I still dont get it. When I was on stock it showed in settings 2 gb RAM. And now Hardware info (app) System RAM 1097?. Same with Clean sweeper.

Nexus 10 has never shown 2gb available, I've had it since launch and I believe the most I've ever seen was back on 4.2 was about 1400MB or so, and it has gone down from there on each update. You never get what they advertise on the box, every single one of my devices has less than whats advertised, my Note 3 is supposed to have 3gb available, but really its only 2.38 after its said and done..
1098 is normal on 4.4.2 for N10, I've attached a shot from mine ... I can only assume most of it is being reserved for the GPU and its super high resolution.

Hi,
As already stated here, just clearing a little the information for you .
The Nexus 10 has a huge screen resolution, therefore it requires a more powerful GPU, even having a pretty powerful graphic processors which is the MALI, it's not powerful enough for the 1600p screen, so they allocated ≈1GB to the graphic unit to prevent any possible issues.
Also, there are some apps running in background, so it takes some RAM too.
Hope this clarifies a little ,

Thank for your help:good:
I did notice that with slim kat 4.2.2 I have 1647 ram available and with 4.4.2 slim kat I had 1099.
so I thought that Kit Kat uses less RAM but I don't really see it with those comparisons.
