Hi guys,
I have a serious doubt that s740 has 256MB. I think that OS only thinks that way. These are the arguments for my doubt :
1. I have an application that shows message box with question before it closes. Usually when OS notices that system is low on memory it starts to close applications. Sometimes while this application is in background, message box pops up (not because I tried to close it, OS obviously thinks it is low on memory)
2. I have never seen significantly less than 100MB of free RAM in any applications that shows that information
3. I created an application that loads some text files into a memory. I started it when my device was close to a 100MB of free RAM. Very soon I got OutOfMemoryException although I had 100MB of RAM left!!
4. Once I bought 32GB SD card from eBay. After a test I figure it out that card was 4GB although it appeared to any PC it was 32GB. I saw on the some forums that I was not the only one with that problem. Many face the same when buying SD card from eBay and China. Point of this...it is possible to alter memory controller in order to trick the system.
If there is anyone who saw in any task manager or something less than 100MB of free RAM, please report it here. Also if you know some way we can be sure that there really is 256MB of RAM on our devices please let us know.
I got less than 100MB free RAM ...
Yep, me too

Actually you don't.
On your screendump you can see clearly "0.12G" (about 120 MB) free from a totall of 0.18G

Actually, I do.
.12G is used, 61mb free, which comes to a total of .18G

Not wanting to nitpick (as the issue mentioned at the start is the question if there's really the advertised 256 MB RAM, which actually appears to be 187 MB), but you're reading the Resco System Info incorrectly.
As you can see on your screendump, your 16 GB (14.83G) storage card is almost full (red bar, 97%) with only about "0.40G" available. This is shown on the right side, just like the ".12G" or about 120 MB.
Whoops, you're right. My bad. I'd suspect that the "missing" mbs are taken up by the os itself? either way, I have yet to run into an out of memory error on this device, and i have constantly up to 5 progs running in the background...

The way OS handles automatic closing of application is rather complicated and does not depend on free memory only.

Windows Mobile 6.1 is still based on Windows CE 5 core, which allows 32MB of memory per process (see http://en.wikipedia.org/wiki/Windows_ce#Versions). Bear in mind that you are also using .NET, which in itself is a bit memory-hungry.
All-in-all I think that device has as much memory as advertised and see no reason why it shouldn't.
BTW my s740 has an 128MB of RAM ('not for sale' version)
CPU
CPU Frequency
RAM
Program memory: OS
Program memory
Memory in use
So maybe some of the Roses can be with 128MB only
...When I used my s710 (64MB of RAM) I had a free RAM value about 10MB. Now my s740 with 128MB of RAM but free RAM value still about 10MB. Very very strange
Hello!
I've had the atrix for a couple of days now, and have noticed that some ram is disappearing.
I use advanced task killer, but I don't have it set to autokill. Instead, I just press the widget as a kill button occasionally throughout the day. I haven't modded the application to kill certain things, or to not kill certain things. It is functioning just as it is downloaded.
So in the morning, after a fresh restart, i pressed the kill switch and i had 550 mb of ram (roughly). This was constant for a few hours. then around lunch time, i pressed kill switch and i had 460 something. Than now around dinner time I have only 370 something mb of ram.
Is there something that I'm missing? Like system apps opening throughout the day that are unaffected by task killer?
Anyone have any advice as to managing apps because the atrix (and motoblur) try to run a lot of them.
Also, I thought this phone has 1 GB of ram. I guess some of it is tied up in things behind the curtain
Check the ram usage on your computer, install a few programs that have services that run, then look at your ram usage.
Same thing.
regarding the ram usage. I cant figure out what the phone is doing with 500mb of ram all the time. This os is able to run on other android devices with only 512mb of ram and consistently have 200-300 free mb of ram. What is the Atrix doing with all that ram?
being prepared for docking...
Webtop/media center/ etc...

RAM not used is analogous to RAM not present in a way.
Android loads and keeps apps ready in memory for quick launch times. They are just loaded and kept, 0 CPU usage for any of them.
If u want to know more, check the thread 'android memory management' (link in my signature).
How much free ram memory xperia mini have ?
And does it have 512mb total ram or something like 418mb ?
Story is the Xperia has 512M of RAM, but 177M or so of RAM are taken up by the O/S. Leaving something along the lines of 335M free for other apps.
I don't know why all the programs that report memory don't show the memory reserved by the O/S.
Would be interested in knowing if such an app exists.
Mike
can u post screenshot of ram memory status ? so if i'am understand u, xperia have 335mb free ram with stock rom ? thats cool

That's the theoretical amount of memory, when I run max kill, I end up with 191MB.
If you go by the utilities they show you total memory its 335mb
Mike
ok, than it have 355mb ram not 512mb is 191mb of ram enought to run hd games ?

It's truly 512MB RAM, but the operating system (Android) also occupies RAM, for example in panamamike's case, the OS uses 191MB for its running so the amount of RAM left for other programs is about 512 - 191 = 355MB RAM.
I haven't tried any HD games but you can watch these videos :

Actually, the math goes like this.
512MB total - 177MB [Hidden by Android for system] - (166-170MB) [Android O/S apps] 22MB [Kernel] approx 143MB available to the user. Max Kill, kills some of the Android O/S stuff, but it starts right back up automatically. I don't know enough to determine if I can really turn some of that stuff off, but ATM I'm just letting it go.
Also note, if we could root the phone, there are applications that SE has installed as part of the O/S that could be removed to free up more memory.
It's a bit disheartening to see such little memory truly available. I don't know what typical HD games need to run.
Mike
i don't understand, if system hide 177mb ram for system, why he(system) double use ram memory ? 1. 177mb and 2. 166-177mb(for os and apps) why ?
never mind, thast cool phone..
Most apps/games store the big files /data on yer sdcard. The app needs to have this feature implemented.

What is the other 700MB being used for?
Seems very high for OS etc., especially considering there are Gingerbread devices with only 512MB (Wildfire S etc.) and they still have a few hundred MB for apps etc.
I would've thought Sense would need more space than SE's customisations aswell.

What sony Ericsson has said is correct and what you saw is also correct
When you see specs in Se website,it say 1 GB internal means 1 GB default Memory/RAM but when you look at your phone it shown different because default Memory/Ram is used by system software and scripts and this varies between phone.
1 GB is default amount and when SE installed OS it got reduced by some amount,when you start the phone the phone loads all its software and processes in that default amount so it again get reduced and now you install your softwares and run apps so it gets reduced again so over all you get 300 MB for your self ...
I have Sk17i with 512 Internal,out of which i get 420 MB free but when i start phone i get 320 MB free for my self ...
I hope you understand
Don't forget to hit thanks if you find it useful ....
You need to consider what storage space is talked about.
There is internal flash occupied by android system and applications, which is persistent. Than there is RAM, which usage depends on what applications are currently running (non persistent type of 'storage').
And there is external storage - sd card - which contains additional data. There is lot of stuff coming with the new phone. That stuff should not really be needed - there are some intro videos in multiple languages, documentation, pc companion sw, ...
I guess that the sdcard content may be erased altogether (if the sd is mounted in PC while phone is connected via USB, the phone does not use the SD card and still runs).
I'm aware of the different kinds of memory in use in modern phones. For the Ray this means:
512MB RAM - Not what I'm talking about - Used by running processes.
4GB External storage - Not what I'm talking about - SD card used for additional storage (media mainly, plus some apps) and basically empty when phone is new. 4GB is supplied with Ray and but be swapped out with cards up to 32GB, although not easily after you've installed apps to it.
1GB Internal storage - This is the storage I'm talking about - Used to hold phone OS, default applications etc., with some left over for user data (apps, media etc.), commonly quoted as being 1GB in the Ray (although interestingly not by SE themselves...) with 'up to 300MB free' for user data.
Most review sites quote the 1GB internal storage figure, although after checking the SE site I'm inclined to think that 512MB would seem more in line with the free internal storage quoted.
Having said that, the Ray's closest cousins (Arc, Play etc.) are all quoted has having 1GB by SE and they too are only quoted as having 3-400MB free for user apps.
Compare this to a phone like the HTC Sensation and things start looking weird. It too ships with 1GB storage yet has ~800MB free out of the box. Most other phones are similar, regardless of the size of the internal storage, i.e. 2-300MB used for OS and baked-in apps.
SE seem to need 700+MB for effectively the same thing.
Anyone know what is going on here?
Ignore me...
Internal storage 1gb is including 512 ROM and 512 Internal memory out of which about 420 mb is user visible
Well, we all know the ray has 512 MB of RAM built in. But if you use tools like Android Assistant, it tells you you can only use about 332 MB of it. I searched in other forums and found out, the "hidden" part of the RAM is reserved for the gpu. My question now: is there a way to reallocate the RAM and get some of the reserved available for user apps? Because i constantly get freezes wit oom.
I dont how to do it , but i am also disappoint when i saw ray has only 315+ RAM , sony site says ray has 512 MB
I am sure if we try to re allocate it we will get problems , why not you try cyanogenmod ?
it is faster and less RAM intensive
i am running on cyanogenmod 7.2 , but if i use launchers like spb shell 3d , my free ram, even at reboot, max caps at 110 mb. thats nothing.

i think is possible but it will be worst! most of the phone speed is given by the gpu (example samsung galaxy ace has 800MHz but lower gpu alocated memory and the phone speed is a disaster)
I think the only way to 'gain' some extra RAM is enabling SWAP.
On my old samsung, I once had a swap partition of 256 to extend the memory.
The good: you have real extra ram
The bad :
-swapping is slowing down the phone, as the sd-card speed is never sufficient.
-SD-card will die sooner, as you read/write a lot to same partition.
So swapping is not advised to my opinion, and others.
Some way to make some memory free (and speed up your phone) :
Use a clean rom (like 4pda.ru) and with the "autostarts" tool, try to disable android apps that automatically try to start itself at boot, startup or other events.
I found out that a lot of android apps try to start themselves even when you plug in the power cable (google maps for example), or connectivity changed, application installed etc.
With the autostarts tool (or rom toolbox) you can influence these triggers to prevent apps to startup themselves in the background.
