Is there a app or a way to partition the internal memory to use as system ram? I use Swapper for root but it just doesn't work as well as I'd like. I know they loomed into a while back and concluded that the speed of the memory wouldn't work for processing ram. Anyone know?

Scientifically impossible. However, there are apps which use memory "like" ram, to enhance performance(they are not really that much of improvement) but I believe 1GB is enough for doing anything possible on a phone.

What are the possibilities of using our 2gb of ddr program storage and re allocating it as system ram?
Even if it isn't pure flash (slow speed) I imagine it would be better then nothing, we could always store programs on the sdcard.

very good, this post actually explains how to make a swap file (on /cache which is fast nand!).
if you want a swap partition you could a) use part of the 2gb /data partition for a new swap partition which you create in a project-voodoo like manner -> not very easy to do as you would have to repartition /data before boot OR b) just make a 2nd partition on your external sd card to swap on. a lot of people (me included) actually did this with their htc magic.
but to be honest i don't think that you will gain any speed improvements with this, on the contrary your system will be slower an more laggy... i found swap even worse on the magic with ~90mb of user-available-ram. if you want to try it nevertheless, it think the swap file on /cache would be a good start!

If we go for b, will the sgs detect and use the swap partition or do we need to do something else.. I still use my htc magic along side my sgs

i have tried using a swap file, but i didnt c any improvements, and the usage was about 500kb only
I recall that on liquid we managed to use a ramzswap module, which fakes a zipped swap partition in ram. It causes cpu to work a bit more, but it was still efficient.

you would have to repartition our external sd to have a second (linux swap) partition.
then use mkswap to set the partition up and after that call swapon. swapon has to be redone every time you restart but you could place it in a playlogos1 script to automate that.

compcache?! ... i guess this would also be a good trade off for our galaxy s because the cpu is definitely not the bottleneck here...
btw. a good read about swap & compcache from the cyanogenmod wiki: swap & compcache

Bad, bery bad idea, MoviNand is not in any way releated to DDR. It's waaaay slower.
Also, RAM is designed for virtually unlimited data read/write counts.
NAND memory is not.
What would be the benefit of using swap space? Nothing. Data is being read/written in filesystem in the end. No improvement in performance. (It could be seriously degraded).
This behavior is totally against Android core design principles. Android doesnt use swap because it doesnt need to. Programs not fitting into "RAM" are being closed with their state remembered. When program is re-launched it is loaded from filesystem and its state is being restored.
If we had "swap" space, it would become really messy. Just imagine:
System wants to close program X, resident in swap, it needs to:
- restore program from swap to RAM (talk about additional ram needed)
- close program, resulting writing state to FS.
i was talking about this sort of thing with Ryza and Voodoo guy they said it was too much work
i'm forward with the idea of using a Swap drive in RAM or external SD
to prevent over usage on the internal SD
This means external SD would need to be powered up at all times -> battery drain (it is present with APPS2SD - or whatever this name was)
Wuld this mean that we would have extra ram available for running apps...like SGS task manager will show more than 311Mb RAM ?
If this is the case then I am very interestied, since I don't care about speed so much. I just need to run an app that currently can not run due to out-off-memmory (needs 130Mb of RAM) for pure presentation purposes
There is a app in market called swapper2 which can make use of the swap partition or creates a swap file for use. I had been using this app since my HTC MAGIC and now on SGS.
I'm currently using swap partition that had been created earlier in my class 6 SDCard. Works on both eclair or froyo kernels on SGS. So far I am not complaining, with swappiness 20, there is not much of memory hog or lag due to opening too many apps or single memory hogging apps (like flash on browser) on my XXJPK, the swap memory gets allocated and deallocated as you can tell from the swapper info feature.
But the battery effects is something to think about though, sdcards are cheap so I don't mind sacrificing it. The other way is to create a swap file on the rfs and use it if you value your sdcard. The screenshot provided is a normal usage of my device with a few apps running at background (Still gonna be 300+ RAM, nothing magical about it though) and I had also used minfree tweak on the kernel.
You can try and see if it helps in terms of performance for a few days. I cant vouch for the swapper a lot as I'm using it myself - I am more uncomfortable without it though. What Xan said does makes sense but there are rare times when the things that doesn't makes sense gives us surprises.
A good read up and comments from people who had tried and used it in different scenarios...

HEY XDA DEVELOPERS
today my thread is about increasing ram
Your phone’s RAM is a very essential component which plays a vital role in the speed and the performance. if you have more RAM, it means the processor have more storage capacity to process more and more temporary functioning files, and hence it can freely work which ensures the device is fast enough. But if your RAM is low, the processing power of the device is affected. Like if you have a low RAM< you won’t be able to play high end games on your Android Smartphone, or even ti might lag while doing simple tasks such as seeing a video, typing a text etc. So if you are suffering from low RAM, and want to get rid, you are at the right place. By reading this post you will be able to know how could I increase the RAM
Things before increasing RAM ::laugh:
Before you actually start out to increase the RAM of your smartphone there are a couple of things you need to know. In this post we will use a app to increase the RAM and this app requires root access to your phone. So make sure you root your phone before starting out. Also note that there are some issues with this app as roof uses a swap file that will be made on your SD card and hence used as ram but as some of the Android smartphones so not support swap file so this app won’t be functional in that case, so before starting out make sure your device supports swap file. You can check the device compatibility with swap file using this app. If it says it fits support follow the steps in the post to increase the RAM of your Android smartphone otherwise you can also increase the RAM of your smartphone using the link below and the link below will also work for unrooted users so in case you are unwilling to root your device to increase RAM you can also follow the below tutorial.
ROEHSOFT RAM EXPANDER :
This RAM expander app is one of the best app available in the play store which allows you to easily increase the RAM of your Android smartphone. So let’s begin with the process to increase RAM using ROEHSOFT RAM EXPANDER. Have a look at some of the features of this app to increase RAM of your device.
1 Swap memory file upto 4 GB ( In simple words it can increase ram by 4 GB depending on your device and memory card too)
2 Widget for PNP swap
3 Detailed analysis of your memory and details about it
4 Swappiness kernel parameter already set.
5 Very easy to use and create swap file and really simple interface
6 It will work with most of the Android devices.
Download from attached files
Pre-requisites :
Here is a list of things we will need before starting the process to increase RAM.
A rooted android phone, so if you haven’t yet rooted your phone first root your device as this method only works with root access to your device.
ROEHSOFT RAM EXPANDER app, you can get this app from play store but you need to know that this is not a free app. (though you can number of apk files for this app but most of them won’t work due to license issues but you can try them, if they worked it will be your luck ).
An external memory SD card installed on your phone.
How to Use ROEHSOFT RAM Expander :
So file the steps below to increase the RAM of your Android smartphone now.
Install the app on your device on which you wish to increase RAM
Now after installing the app choose your default language.
Now to increase RAM create a SWAP file by clicking on the SWAP Active and enabling it
After the process is finished just click on the grey colored box and activate the swap file created.
Congratulations you have successfully increased the RAM of your Android smartphone.
This increased ram will not show in the task manager but you can feel the change with the overall performance of the device which seems to be boost up. If you already have a decent ram them got might need to run some very heavy game to know the difference in performance. So I hope this post helped you in increasing the RAM of your Android smartphone.
Hi there,
I have the ZF2 with 4GB of ram. After a couple of days of usage, it seems impossible to lower the ram usage below 1.8GB even when I clear the cache of all apps.
However, when I restart the device, my ram usage is below 1GB.
I have uninstall or disabled every app I could without rooting. & I don't want to root now.
Nonetheless, I would like to keep the ram usage of my device as low as possible (2GB of ram use seems a lot to me, especially when I have one or two apps open)
Did you find a tricks or ways to keep 2gb or more ram free at all time ?
Thank you.
Simply, there is no clear way and those numbers are normal. The best memory management is with native linux, not yet available on zenfone 2.
What's the point of always having 2gb of free ram? RAM is completely useless if you aren't using it.

It's not a question of useful or useless. It's a question of is it possible and if yes, how.
Yes, keep the phone in deep sleep with all apps closed and disable everything in autostart , better yet, you can just power off the device
p.s: not even custom roms will run that low, I had cm12.1 with lg g3 3gb ram, I disabled basically everything and phone will still boot with at max 2gb free ram, maybe 2.2gb if you start killing launcher and sytem apps lol
4Gb ram with 2.2-3Gb free Ram is plenty for a cellphone. Its even plenty for a desktop unless you run hard core 3d games like crysis.
The lowest I have seen is 150Mb/1Gb usage with Nexus 7 v1 tablet yet it was hell slow. Note that the more Ram you have, the more the system will use it and cache in it. This will increase apps loading speed since they are directly loaded from Ram vs local storage.
I would love to have an app that lets you select what to cache in Ram, e.g. large high-resolution PDFs that take forever to open and load :crying: I have 300-800Mb PDFs that will take 1 min just to open.
Indeed, an option to decide what to cache would be great.
Can we expect less usage and caching with the 5.1 update or with a custom Rom?

hi all, I have a little question on s4 mini duos I9192.
using "free" or "meminfo" commands displays memory informations, the phisical ram displayed is 1,3 gb but the phone is declared 1,5 gb confused , so I thought it will be some zram but analising the memory its not zram.
by the way there is a swapfile of 1gb.
please can someone confirm this? I am playing with swappiness value and I must be sure if I touch zram or swapfile
screenshot attached
I'm guessing your using stock os as that uses a 1gb swap file. Zram is kernel dependant and I don't think stock makes use of this. Although our phones have 1.5gb RAM some of this is stolen by Android OS. The same with our 8gb storage which part of is stolen by Android again leaving us with around 5.5gb.
Would like to know how you get on with different swapiness values, and which you decided to settle on.

Thanks, yes I'm on stock.
I noticed that the 1gb swapfile is little used; with swappiness 100 swapfile is used about 200mb and with swpss 20 about 40mb both after 1 day of use;
Also the used part tends to accumulate and grow from boot but I shutoff phone at night so swapfile resets at boot.
My idea was to delete swapfile to recovery space bit I can't, swapoff doesn't work.
Anyway I think phone is smoother with low swappiness and with medium usage I never suffered lack of ram problems.
hi !
swap & Zram are completely useless for a device like ours .....because we have enought RAM and enought power .
thes two are develloped and used before for old low and middle devices
the best is to grenify or freeze unused apps and services for a more lighten rom....

Yes, already greenyfied all and removed all bloat and useless apks.
My doubt is why stock rom has a so large swapfile, a waste of space

Hello. How to increase RAM to 4-6 GB? Who can become a donor?
Sorry for my English. My Google Translate Assistant
You can't magically "increase" your hardware RAM to 4 or 6GB, but instead you can set a virtual ram environment using internal storage, which helps the hardware RAM to not force close any background apps due to no ram available, install this app (https://play.google.com/store/apps/details?id=com.allakore.swapnoroot&hl=pt_BR&gl=US) and set the space that you want to reserve for RAM swapping, you can even do it without root.
Thnx)
Unfortunately, software magnification does not solve the problem. I wonder if I can raise my memory mechanically
I know it's possible. On other devices
