How come my transformer onlyy show less than 400m memory available in the task killer?. I removed all the Widgets and haven't install any extra apps besides angry bird games. The available memory still showing less than 500M. Hows your transformer available memory show?
With 512 MB RAM you get 100-250 MB of free RAM, so >400MB is more than enough for everything !
And you have 1GB for USE not for FREE/USELESS ...

It is.. but the graphics and the OS take up a chunk of it don't forget.
I've seen this question pop up on ever forum for every 1GB device I've looked at so far. There's 1GB of RAM minus what the GPU uses minus what the OS uses. Should be an automatic sticky.
I recently bought a One S and one thing that has really been bugging me is the fact that I have much les storage than advertised. It says that you get 16 GB, but the actual amount is 12.14, and
2.21 of that is internal memory so I only actually have 9.93 to store my media. Why is this? Also it says it should have 1 GB of RAM but task manager says I only have 650 MB.

16 GB storage is partitioned and some RAM is reserved for the system and the GPU.

First off no hdd or flash memory is ever 100% as advertise because its been formatted to run. That's why there is only 12gb instead of 16gb. And that 2gb is the space dedicated to app installs. And the remainder is for you to do with however you please. Music, videos, extra game data (like many of gameloft games where you need to dl an extra 500 MB or so) or whatever you else you want to throw on other then an app install.
When you see an app in market and you download it and install it, it goes directly to that 2gb partition. If you download an app from a third party website it first goes to the 9gb space and once it installs it, it installs on the 2gb and all you need to do is delete the original dl .apk or keep it as a back up.

The above answers covered the answer so no need to reiterate but I just want to opine that you should consider yourself lucky, HTC doesn't rape you like Motorola does. On the Razr and Bionic, they are advertised as 16gb internal but only 8 is accessible to the user. They allot 4gb for apps and 4 for the OS. Bonus for them is obviously expandable memory.

System takes the resources
On many phones the preinstalled software takes a lot of space. I would recommend to install another ROM. I always do that to get rid of the software I don't need.
Ok. Thanks for the help. But what about the RAM? Shouldnt all of it be available?

As already said, some of the RAM is reserved for the system and GPU. For example my HD2 should have 576MB RAM but it only has 411/403 (depends on the ROM/Kernel I guess) because 128MB is for the GPU and the rest is used by the system. I never actually get that much free RAM (I never get more than 200MB free, and that's only on startup; normally I have around 130MB free) but at the same time it's never really been an issue.
Ok. I just though that everything was shown together because I always have 500 MB of RAM used even with all applications closed.
The phone will still reserve some RAM for itself, and that is not the best indicator of RAM that's actually in use.
HTC One S is a gorgeous piece of hardware. To bad they didn't add sd card support...

System software installed on separate partition usually. So removing them will not add more space to the user data.

Hi! I would really like to buy this tablet but I heard from somewhere that the tegra 3 gpu and cpu needs 500mb of ram so that there would be only a half gig left to system.
So could somebody tell me what the available ram is for real on that tablet and is the amount of ram enough? And also is tf700 really worth the money?
Thanx in advance

You shouldn't judge it on how much ram it has left. RAM can be used to pre cache apps so theres no loading time. Different manufactures tweek the way android handles RAM. A tablet with less available RAM can run faster than one with more available RAM

There's not a lot that you can do to clog up the available RAM on this thing anyways....Even if you had 500MB available, what kind of applications can actually fill up that space?

I don't know how much RAM is being used, they're not available in the US quite yet. I can only guess that the system will use 500MB or less. On my Bionic, I don't have a big problem of not having enough RAM, so I don't expect it on the tablet (especially since the OS on the tablet is much cleaner than on my phone).
Worth the money? That's up to you. It has the best specs on the market right now and has the awesome keyboard dock, so I think it's worth it.
Listen to ian1, he had something important to say.
Also remember that Android has its own way of not only freeing memory used by running and idle processes, but also of managing various kinds of memory - it is not free/used dichotomy, you have to count in shared and buffered memory (you can actually see it in various OSs nowadays). I have about half of Infinity's 1GB RAM available normally (and right now), which is AFAIU free+buffered mainly.
The TF300 has a LOT of ram available on boot up. Almost a full GB I think.
Free ram is NOT a good indicator of how fast/usable your device is. Android is based on Linux, which has a philosophy of free ram is wasted ram. That is, your device will actually be faster if its ram is full. This is why task killers are considered to be so bad on Android. Just let Android manage itself and don't worry about it.
Ok thanks all I think i'm buying the tf300

You have 976mb of ram most of it is used though

I am wondering if anyone of you feel suspicious about RAM consumption on android?
Here is an example:
Galaxy tab 2 7" listed with 1GB RAM, but when viewed with stock task manager in RAM manager section, the RAM available is not 1GB, but rather on some 687MB. Furthermore, from that 687MB there is some already used by apps. Even on newly bought device with no open apps, the amount of used RAM is around 200MB, so that leaves only approx 487MB left. Even after using task killers, there is still hundreds of MB used RAM
When I search for why the RAM is not 1GB, people answer its because its reserved by android.
When I search for why there are used RAM when there is no open apps and on newly bought device, people also answer its because its used by android.
So I would categorize the problem as "the missing RAM" and "the used RAM" and ask these question:
1. If the "missing RAM" is reserved by android, then what is using the "used RAM"?
2. If the "used RAM" is used by android, then what is causing the "missing RAM"?
Does that means android double use the RAM? or is it something else?
Please enlighten me.
Great question, and I have been wondering the same thing. :thumbup:

Now dont take these notes to serious I'm not working in these factories,places where they do this.But this is MY theory.
Tab2 should have 1 gb ram right
Galaxy s2 should also have 1 gb ram right
So why the hell when i install cm in both ram in s2 is 827 mb and in tab2 is 687 mb it is driving me mad !!!

I do realize 1GB is not 1024MB, but at least task manager should show something around 900MB like you said.
For the Touchwiz theory, I also think that it might be the culprit of the "used RAM", but i don't think it would be that much, but that's because I'm not including google apps on that. So i think your theory might be right.
Selim already answer the "missing RAM" part, it is the same amount on custom ROM, which means they DO reserved by android. And that leads to how much is the "used RAM" part, is it more "sensible" without the bloatware running around?

There are settings (in Android we call them "minfree" settings) to tell the system how much RAM to leave free and available, but the rest is designed to fill up as fast as possible and stay that way.

For most android devices, the true available RAM is always less than the stated figure, like GT2 has only 687MB, HTC One X has 976MB even both devices has 1GB RAM
Those missing RAM are not stolen, instead they are reserved by the kernel for hardware of the devices. Don't blame anyone for this, this is crucial.

That is an interesting concept of memory management.
FYI, I'm not freaked out, just wondering where the memory goes, is it effectively used or eaten by some "rouge" apps.
Thanks anyway
However my Galaxy Tab plus with ics had about 800 mb ram in the task manager. Now (yes, my gtab plus has been stolen... grr) I have the tab 2 and I see only 687. Really strange, don't you think?

RAM HELP
can someone who has well experienced with different ROMS for tab2 7.0(p3100) help me??
i originally had ICS 4.0.4 which displayed around 680 MB ram, then upgraded it to 4.1.2 jelly bean which displayed me 770 MB RAM.
i though as custom ROMS have seldom bloatwares, atleast they should display more memory, but to my surprise i found 691 MB RAM on the latest nightly build of Cyanogenmod 10.1(jelly bean 4.2). I ve not used the AOKP jelly bean ROM due to limited internet(downloading) at my place.
as i am having a LIMITED FREE INTERNET USAGE, i am not dowloading more ROMS until some one finally helps me with the fact that
"WHICH ROM DISPLAYS MORE MEMORY FOR TAB 2 P3100??????" so that i can download it the next month or via some other network
I don't think you for it, the missing ram is the system. The tab has 1 gig to start, but whennyou fire it up, the system has to use resources. The same way a computer says it has 2 gigs, but if you check, it is lower. The reason this changes from rom to rom is because each system has its own ram management. Does this help?

It is like that for absolutely everything. PCs/Notebooks, Tablets, Phones, etc. It's normal.
Just remember one thing that with a build.prop edit (by adding a line) you can fake the available RAM in Settings/About phone (like you can show some CPU info), but I don't know if some apps detect it (I think but... not sure ).
Maybe something like "ro.product.************" .
Maybe a Google search will give you the trick, just a cosmetic thing since the real available RAM is "hardcoded"

Yes, but those are dedicated "add-on" cards and are generally limited to PCs and gaming notebooks. The OS would still be using the main system memory. If you had 16GB RAM, the OS and any other processes would be using it regardless. You would never have 16GB available to you. Also, even if you had dedicated memory on the graphics card some of it will also be used regardless without your knowledge.
Any SoC uses the systems main memory.
If you want the full 2GB available to you, have fun never turning on your phone. If you want 2GB only for you, then the system has nothing to run on.
Memory is there to be used. Having a separate section for the OS and 2GB only for your choosing is pointless and inefficient.

its not out of 2048MB for one
its 2GiB, not 2GB
from wikipedia
Although most manufacturers of hard disk drives and flash-memory disk devicesdefine 1 gigabyte as 1000000000bytes, software like Microsoft Windows reports size in gigabytes by dividing the total capacity in bytes by 1073741824 (230 = 1 gibibyte), while still reporting the result with the symbol "GB". This practice causes confusion, as a hard disk with an advertised capacity of, for example, "400 GB" (meaning 400000000000bytes) might be reported by the operating system as only "372 GB" (meaning 372 GiB). Other software, like Mac OS X 10.6[5] and some components of the Linux kernel[6] measure using the decimal units. The JEDEC memory standards uses the IEEE 100 nomenclatures which defines a gigabyte as 1073741824bytes (or 230 bytes).

2 GiB is 1024x1024x1024. HDD / MMC / SSD use GB (1000x1000x1000) not GiB, however this is for storage. RAM is usually binary 1024... so it most likely is out of 2048.

Oh, well don't worry, you have 2GB RAM. It might just be the way it is displayed in Antutu. CPU-Z displays the total amount of RAM as 1855MB. Not exactly consistent between programs.

I will just try to ignore this and I will be happier I guess, my cpu-z still says 1794MB total ram.
The device has 2GB of RAM but you the "BIOS" or whatever controller is in there allocates some for itself and the hardware in the phone (mainly GPU) and the rest is left to the OS.
Sharing RAM is good in general but many systems require X amount of RAM whether it's actively being used or not as it's designed to be able to use it. if it were to call on that memory address and it's full the system would crash (or a STOP error).
So instead of sharing it and allocating it as needed, it's locked off totally from the OS in the event it's ever needed by the hardware.
