What does RAM swapping do?

expands ram memory , for example if you have 500mb of ram in yor device and you need extra 200mb you can expand it to your sd card only work on rooted devices

It buys you more virtual memory at the cost of speed. I.e. it will look as if you've got more RAM, but since larger parts of your virtual memory now in reality resides on the SDcard, it's not as fast as before.

How much ram are you getting in the android app manager in settings > applications >running?
I am getting well under 1gb, 360mb free 180 in use, so only 540?!?

hmm... mine says the same thing???
Ram gets used up by the OS, background services, the launcher etc, caches etc and gets freed up when necessary like most modern OSes. S tablet has 1 gig of ram to put it in perspective I usually have around 400 or so free according to task manager when not running *anything* but only had like 200-250 free on 512meg Viewsonic Gtablet.
the sony tablet has 1GB ram, the system itself takes up around 400-500MB RAM so that it can make sure the OS can run smoothly, the remaining 400-500MB RAM is available to you for additional apps and stuff
So are you saying that the RAM the system uses won't show up in "in use"?
I think that's why he says. It is the same as the internal storage. If you add up (mine 16gb ver) the 9gb + 4gb, you get only 13gb instead of 16gb.
I was confusing about it before. But I went to BB and tried other HoneyCome tablets. They all give the same thing.

Yeah... what's with the 13gb. Noticed the same.
I'm already down to 6gb of the 9gb reported. Zinio ispretty heavy on its content.

1,2Gb of 32Gb is free and Razr's annoying me by low storage notification.
Possible to disable?
yes it's possible...leave 2gb or 3gb free of the 32gb memory and you 'll be fine...lol!

You are right - the notification is really obsolete and annoying... :-(
Hope there is some way how to disable it...

because 2,5 gb free of 8gb is still fine... as far as I remember on 8gb card its usually notifying when there is 200-300 mb free... the notification is rised where there is < 5% space free...
Is there any way to overclock ram?

why you want that, better speed? or more memory? i don't think that is "possible"

No, RAM size is fixed in the RAM chip. There's nothing like a Linux swap partition/Windows ReadyBoost to help with this.

No not possible, but if you install cyanogen mod you can make it compress the ram, that you basically have more free ram than before. That is what i do.
Update My rom
Hello everybody
I have galaxy s4 clone I would like to update my rom :
Model Number : GT-I9500
Android 4.2.2
Baseband Version : I9500XXUAMDE
Kernel version 3.4.5-I9500ZSKJ6-CL679970 Sat Aug 10 19:17:34 CST 2013
Build number :GINGERBREAD.ZSKJ6
Custom build version galaxy.20130810.F.V015
internal storage : 344 Mb
Ram : 311 Mb
Please Help Me
Use swap file. Just google it. Even though it's slow it's worth a try.
Yeah @aymenmeer ,you have been helped by me

You won't be able to add more RAM but you can add swap to your SD card storage to be treated like RAM but it will wear out that SD Card in a certain amount of time. It's also slower than regular RAM but Class 10 SD Cards are still a nice way to add swap to be used like RAM if you need it.
I used ROHESOFT Ram Expander for that reason (got the free version since I wouldn't pay an absurd price) but I was able to use an extra 1GB SWAP treated as RAM or 500MB on my S3 mini. I did have to change swap parameters to speed it up though and best experience. It was actually fairly smooth for the most part but not always recommended.
Greenify I used to reduce background processes from using RAM as well.
Other option includes zRAM or zSwap from kernel adiutor and custom ROMs for less RAM usage. Another way is this Xposed Module called Low Ram Device which you can force your device to act as a low RAM device , which makes applications use less RAM and significantly free up RAM space.
However for a device with less than a GB of Ram or 1GB, I'd say use Low Ram device Xposed Module , reduce background processes and importantly, add swap to your class10 (class6 or above is fine too sometimes) SD Card to be treated as extra RAM . It may feel slower but not too slow and the difference is less noticeable with faster SD cards .
As for overclocking RAM Speed, I don't believe that's actually possible on even a custom kernel yet but I'm not so certain. I found this thread by Google search Overclock android ram speed.
overclock ram is different overMEMORY. ram have bus clock (amount data can transmitted) overclock ram mean make ram faster when transmit data, does not help improve memory shortage.
Question to the Dev's...
Is it possible to use some space from the phones internal storage or the sd card to use it as virtual ram memory? I have noticed that nobody has done something like this and i believe that for the xperia u it would be very useful because of the really small ram size.
Along with a debloated rom the phone would be very capable.
Cheers

Unfortunately, the thread doesn't really discuss how to use swap to "add" more ram on XU.
I use a swap partition on my old phone with a class10 sdcard. Since it's a really low-end phone, simple tweaks like swap show a noticeable increase in performance. For phones that have an internal sdcard, is it feasible to use swap? How about performance-wise? Do our kernels have swap support?

Very capable of what?
Keep in mind that the guys in Google (and the guys working for Sony) are not complete retards and might know what they are doing, and if they thought there was an advatage for it they would have done it.
Virtual memory is not RAM, and the only way to add RAM is.... to add more RAM, which you cannot.
Swap file does not address performance (obviousely it reduce performance rather then increase it), it address physical limmitation(of maximum possible RAM) or cost.
Android has mechanisms to deal with low memory situations, which maybe don't seam very attractive to users that are used to 3rd generation Intel processors with 8GB of RAM, but make perfect sence for portable low power devices.
For example,
Assuming you can have 10 messages visible on screen.
In principle, messages will hold in memory only the messages that are visible on screen + a few more above and below it, so lets say 20 in memory total, and while scrolling old messages are being discarded and new ones are fetched.
Would it be faster to write the memory to a swap file when memory is needed and read them from swap when messaging is visible again, then just fetch them again when messaging are visible again after it has been killed when in background and memory was needed?
Note that a "normal" windows application may not even bother to free invisible fetched messages and rely on available memory.

Not accurate, unused RAM is wasted RAM.
The "free" RAM"shown in running is not realy free and usually has lots of cached processes.
Those processes are inactive and will be killed if the memory is needed by another active process, however they are still in memory and ready to run in case they are needed.
So this is ree ram that is still being used andnot wasted.

Thats kinda accurate mate and even @nicolassp said that, but either his own opinion

#PocoF1 is termed as #MasterOfSpeed but giving only 3.4gb of memory for a 6gb phone is unacceptable!Ram management of this phone is simply ordinary.
Please retweet the issue guys
Free ram is wasted RAM in an OS like android, as it becomes almost full, it will automatically clear the oldest apps so you don't need to worry about that. If you're rooted you can use ram management tweaks like changing minfree values.

To run everything quick and smooth. It keeps everything in RAM to access instantly. This happens with most of the phones with 4GB + ram. Don't worry about it

i too was puzzled why , yes free ram is wasted ram theory but i have not installed most of mine own apps yet .surprised nobody bother , what if this phone come with 4 gb ram , it would be maxed out easily
That's not how android ram management works, if you would have 4 GB of ram, the phone would load apps on background up to 2 GB. Free ram is wasted ram, miui ram management is aggressive enough already. You guys need to understand that the phone automatically closes down apps when more ram is needed.

good to hear then , i have been manually closing background apps ,guess a habit , back in the day when ram was 1 gb or less, it was precious, haha
