Im totally suprised because I though that the HTC Jade (touch 3G) has 192MB of RAM but the system does only use 123mb of it :S Is this normal and if, why?
I made some screenshots of my system one showing from the settings and the other from mobile taskmanager...
Thanks for the answers!
If you didn't bring this up, I would have never known about that. lol
I'm assuming the rest of the RAM is for the video, but someone please confirm. Thanks!
On all devices(depending on the ROM you use) your actual available program RAM at startup is decreased from the actual hardwares amount.
For instance, the fuze/touch pro has 288 MB RAM, but when you start the device up you get about 200MB free RAM. With the custom ROM i'm using i actually only get 189.00 MB free Program RAM.
As to what occupies the seemingly unused space, i'm unaware of. All i know is it seems to be taken up by the ROM image.
Hope this helps.
so.. ist there any possibility to hack those unused space of ram with an custom rom or something? I mean 60MB makes about 50% of the ram which is currently used :S
Am I the only one? Is there anyone else noting less RAM then 192mb with his Touch3G?
You can't "hack" it. some ROMs use less RAM and you get a nicer bigger amount of it since your OS takes less space.. you can find a ROM for your device with more RAM space... that's the best you can do.
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 ...

But I thought it has 1gb of ram?

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.
On GSMarena (and everywhere on internet) I saw that Xperia Miro has 512 MB of RAM, but every app (like Watchdog, Go Launcher) that I used shows 401 MB of RAM. I have STOCK Android, no root. Is 111MB of RAM used by OS or it's something else?

The memory figure for anything (RAM, HDD, SSD and what not), is only an approximation. During production of these memory devices, the actual value is almost always less than the figure given by the OEM. Having said that, the OS may have certain uses of the RAM but are not displayed on the task manager.
The carrier may limit the ram, I know the HTC dream was limited to 384mb by tmobile

Approximation of by 10% is very lousy approximation. On PC if you have 3GB of RAM you have ~3GB of RAM, not 2.7GB of RAM but memory figure for HDD and SSD are shown in TB but they are really in TiB (TB=1024 GB and TiB=1000 GB, ...). Does on your phone, your RAM memory figure is smaller in task manager because of OS?
When I go to Antutu or Ram Booster they say I only have 1794 mb of ram what happen to the other 250 mb?

Hi,
Nothing wrong, the rest is for system, GPU (in short)... Not all the RAM is available for the userspace.

Thanks for the quick reply, does this happen to all phones or just the nexus 5?
I feel like it should be better implemented like have 250mb of its own ram or use at it is needed not just take away from me 250 mb of ram.

As far as I know, at least for all devices I owned, it's always the same thing (some devices with 1Gb RAM had something like 768 Mb available stock)...
There is absolutely nothing wrong with the available RAM detected from Antutu or RAM Booster or another apps.

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"

Don't pc graphic cards have dedicated memory?
So they don't take "my" memory

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.

I think what the OP is trying to ask is why is the hardware only detecting 1794mb of total actual RAM? Not how much ram the OS utilizes.

I don't have a problem (well I do but not as much) with the OS and GPU use the 2GB of ram I have available but it should be something like like 300mb out of 2048mb (300/2048) of available ram not just cut my 2Gb of ram to 1794. What if the OS only needs 200 I still would not have 1894mb my max available ram is always 1794.

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.

And that's why they make 512MB RAM modules instead of 500MB

Ok guys i get the gist of it now, thank you all.
Hi guys, as the titles says, how much ram is user available on the 2gb version?
By user available i mean adding the used+free ram.
I am asking this because my nexus 10 is supposed to have 2gb of ram, but only 1.1gb is user available, the remainder is taken up by the OS.

1850 is maximum . if you freeze a lot of bloatware after reboot you have estimated 1gb ram free left.
After a lot of use without a reboot free memory drops to 650.
Memory is not a problem since it is also ddr4.
Also in android less memory left is sometimes better.
