SD to Ram? - Samsung Galaxy SL i9003

Who have tried this mod? I believe ive read it before i just cant see the thread, as i remember its called sd swap (but not that sd swap int2ext)if im not mistaken? Is it worth a try? The mod which gives partition from sd card to expand ram?
EDIT- This one http://forum.xda-developers.com/showthread.php?t=1659231
Who have tried it?

wow .. i ll tried it sooon ....
more ram ..... hhh more Hd Games

Sounds awesome, but the maximum swap of 256 MB is a dampener! Hope someone tries it on their i9003 and reverts if it works on this device.

Up!

Try Ram expander app. It dioes same job. I tried that app but frankly speaking we must need class 10 memory card to see actual noticeble difference.

I have a class 10 microsd card and am willing to try this on my i9003, however, would like to try it before I buy this app. Can someone point me to a trial version of this app?

Tried the Ram Expander app on my SL and successfully created a 1422MB partition on my class 10, 16GB microSD card. Terminal Emulator confirmed the same. (Total RAM 1.44 GB)
Need to test it on some games though, any suggestions?

@coolcowboy Try Real Racing 3! And maybe..... Temple Run 2 and Subway Surfer!

Dude did the app make a difference..

I used this app,(Ramexpander),for a couple of months and didnt notice any improvement on terms of smoothness in every roms i tried. I think its just a placebo.

Tried it on my 16GB class 10 card, and didn't find any noticable difference. What a waste!

As far as I know, the swap is used to cache some memory, not all... it doesn't matter if you make a 4gb partition for SD to swap, it probably will use a max of 256mb.. the way it works it's to cache some stuff there, so you have a little more free memory in your device... You will probably never feel the difference in any device with more than 256mb of RAM memory... plus... reading the SD is really slow... so I don't think it would make any difference to us...

Yup, swap is a Linux tool, used to augment the existing RAM, by using a partition on a disk to store less required pages from the RAM in that partition. It is slower than RAM, and dependant on your sdcard IOPS (read and write speed).
ZRam would be better, but that's up to a kernel dev to implement.
Whatever happens though, these features are just to improve multitasking, rather than loading large games and giving the device a speed boost.

Asking for an app

Hey Guys!!
I was wondering.....is there any app for android which would allow us to use some space in our phone or external memory as RAM like Eboostr on Windows???
Hello,
you can use a taskmanager, some can optimize your RAM periodically!
sorry for the late reply but i just wanted to know of an app for using a part of sd card as ram.........not because i'm short of it............but to increase it

I know what u mean it. But then,no. Bcoz as far as i known,android is based on memory resource. Thus,not use much 2 use ram. And the application are automatically being killed when there are less ram. Thus improving speed.
Just to decrease ram used,i think by using cyanogen or any custom rom that less ram used.
As u said about the sd card as ram. I think that windows 7 use the pendrive or etc as a cache/memory swap. To increase speed.
Correct me if im wrong.

Google about android memory management.
Apps interfering with the systems own management do more harm than good.
@OP
Android already uses swap if the RAM is full.
But you can probably increase the swap partition.
Google or search the forum for "android increase swap" or something like that.
This will require root.

IIRC, there is a mod to use either a partition or a file on your MicroSD card for SWAP space... which is basically where programs that normally reside in ram would go when not in use... think its one by sparksco...
however, I dont see hardly any kernels with it built in these days... its a GOD SEND on my HD2 and Hero... Id love to use SWAP partition on all my devices...
hope someone more knowledgeable about whats out will reply
First this is the wrong thread for questions and answers.
And yes we have a few kernals that allow swap. But the rom as well needs to have that available from what I recall. Think cm uses 128 max though. I know there is a miui rom that uses swap here too. Does come in handy. You will need to reformat your sd card for swap if your going to use it. There is also ext3 and 4 and that acts like available storage space for your phone. I would only use 1-1.5 gb for that though. Some of these big games only want to go on your sd card.

One of our biggest supporters of swap has actually decided it's not such a good idea.
And it does not speed things up. It slows things down. Even with a class 10 sd card.

I was using swap for quite some time and it seemed to work really well for awhile and then started to cause my phone a lot of lock-ups after awhile. I think it was just eating up my sdcard too much. And it has been proven that swap wears on your sdcard quite a bit. I don't think it's worth it. There's a script made by Darkky that patches memory leaks in roms that seems to work good. I include these in a lot of roms and my memory always stays above 80mb.

What people fail to understand is that SWAP or fake ram is INHERENTLY IOPS sensitive... that being said, NONE of the Class 10 MicroSD cards have had ANYWHERE NEAR good enough IOPS for SWAP intensive operations... On my HD2 I went through testing 10 MicroSD cards of different Class's and sizes to find out which gave me the best performance while using SWAP and what gave me the best IOPS, Sadly, out of them all, only a Class 4 and Class 6, where anywhere decent enough to be good enough to function as SWAP devices... I mean 4 other ones worked... but you could tell with these 2....

It makes perfect sense... lets take game files from an SSD and transfer them to a HDD... while RAM and MicroSD both use NAND/Flash memory, its still a medium transfer as well! ERGO if you have a crappy IOPS MicroSD card, your going to notice slowdowns and wait times while things in RAM are swapped out to SWAP and vice versa... I guess the best comparison is using the SLEEP function on Windows 7 VS the Hibernation function...

yeah SWAP eats the CRAP out of your MicroSD card... proven fact... HOWEVER, if your like me, 8GB and 16GB cards are rather cheep these days, I totally dont mind spending $10-30 every 6~ months buying a new MicroSD card if it keeps my OLD device speedy... (pun intended)

EDIT2: some things I thought I should point out after I re-read my own post... in the Windows Sleep V Hibernation statement, when in Sleep, the RAM is kept on, and thus requires no loading time, in Hibernation, RAM is stored on the HDD/SSD and must be transferred back onto RAM before it will boot... I also forgot that I backup my MicroSD's contents with Dropbox and Box software, as well as backup's that are performed whenever I plugin my Phone or MicroSD to my desktop or laptop...
There are apps like juwe11's ram app, rom toolbox has a memory settings, script manager in combination with v6 supercharger script (which I highly recommend, as it helps prevent sense reloads), auto killer memory, etc. Each phone has a "brain" of it's own. My phone likes v6 or auto killer memory, but other phones like juwe11's ramscript/app. Trial and error. Good luck, and post your results if you want to.

That is a good explaintion. But personally I don't want to be the guy that releases a rom with swap already in it and get the guilt of someone's sdcard breaking. As drob311 said there's apps and other ways of making it work and my rom/kernel does still support these other ways of using it.

you do know that you can enable SWAP in a rom, but make it contained to SWAP PARTITION only? ergo if they made a SWAP partition on their MicroSD card... hence you have zero liability if said card breaks... you have to have SOME knowledge to repartition a MicroSD card properly for a SWAP partition
BTW, I fully support enabling it that way, it also leads the way to making the script for SWAP file vs partition easier because the ROM is ready for it, its just not enabled unless someone inserts the custom script OR has the proper partition for SWAP!

Yes I know. I already had a swap script for swap partition for cm7 but you need a custom cmparts.apk since cm decided to disable all swap on their roms. Plus I didn't really feel like repartitioning my sdcard once it started acting up. I'll probably just make a seperate add-on to flash over the roms for it if people want it.

im cool with that
actually, if someone can get YES/NO in CWM like on my HD2 you can put it all in the rom and they can choose right at the get-go
that being said, you can still use the custom cmparts.apk even w/o using swap partition... not that big of a conflict since if you have SWAP partition it works if not its disabled... only the functionality is present... and you dont have to maintain a separate script/package/whatever...
also, if your SDCard is acting up, use the SDCard formatter do a full format, then use HD low level format tool... or if you bought HDD Regenerator like me, its easy to find the health of your SD Media... but thats a moot matter... and im done talking for the night i think... (well the night ends in 3min... :X )

You can actually use compcache with out swapping to sd. But any swap introduces latency so it negates most gains achieved. So more apps might not get killed off as quick allowing them to reopen faster but forground apps suffer from the latency and compression.

AFAICT non of our kernels support compcache. It's a patch you have to apply to the kernel itself in order to make it work.

Was great because of the best buy protection. Loved the old device but the shift is like night and day. Don't really use the keyboard. what is all I would need to do to use more swap?

Swap(virtual ram) space?

Before anyone rages at me, I have done a google search and an xda search.
I was wondering if it was possible to use the SD card as a virtual ram or swap space as some may call it. I tend to open tons of apps and games on my g2x and it quickly fills the 200mb ish ram that is available(this excludes OS and essential sys apps.) It would be super nice if i could partition off maybe 1-4gb as swap space and be able to open tons of games and other applications without ever needing to close them.
My G2X specs if it matters.
Cyanogenmod 7 latest nightly
faux kernel version 50
overclocked to 1.4ghz with a slight undervolt.
32GB SD card class 10
Edit: After further research on this, I have found a solution. An application called Swapper for Root or Swapper 2 will create a swap file on the sd card and do exactly this.
You don't want to. Sd cards are slow and it adds a lot of stress on it, decreasing the lifespan.
Am I the only one unable to use up a half gig of ram?
Sent from my LG-P999 using xda app-developers app
I've enabled 700mb of swap on mine and I don't see a lot of slow down. Only slow down I've encountered is with my sphere page changing effect but even so its it barley noticeable but this is probably because of the class 10 sd card.
Current stats on my ram usage according to terminal free command.
mem: total - 381972 used - 367880 free - 14092
swap: total - 716792 used - 126688 free - 590104
with ~123MB being used and with very minimal lag, I think its worth it for the way I use my phone.
That is awesome man. never even thought of that idea. please let us know how it works out after a week or so.

I've been using Swapper 2 along with SD -Booster for a coupe weeks now. And I am only running a 16gb class 4 card, but I do notice a difference in how the phone runs with multiple or RAM hungry apps, and now I find I don't need to use a task killer anymore to resolve lag issues.
I am using:
CM7 Hellfire Phoenix 2.2
Faux 049 kernel
OC usually 1200 with no UV
JIT compiler and Compcache RAM disabled
VM Heap Size 64mb
Swapper 2 set @ 200mb @boot
SD Booster set to 2048kb cache
Few other tweaks. Phone is fast and stable. And I use it heavily from streaming video from my private server on my home network, to gaming tons of HD games. And several of the games I have edited the XML file to unlock Tegra 3 graphics options. I play Dead Trigger on the Ultra High settings and those are for Tegra 3 chipsets and the phone doesn't skip a beat.

I wonder if there's any advantage of using emmc over your sdcard? Since it's internal shouldn't it be faster and less harmful?

There is definite differences between using your internal sd and external. But that depends on the class and read/write speads of your external. As far as swap goes, I do not think there would be much difference either ways since the linux/android kernel is built to keep ram space cleared when it needs it. I am constantly building ics/gb/jb on my linux machine with 8gb of ram and I have only seen my pc go into swap when i leave it on for weeks at a time. Swap only picks up in linux when the memory is overwhelmed. So, I really don't think there would be much benefit since almost all kernels run minfree and other tweaks to keep memory freed up for performance.
I wonder if we can use our data partition for swap or any other partition? Since swapper does have the option to use a partition as swap.

1. You're expecting a link?! Should I pay for it, too? :S
I use a Sandisk UHS-1 64GB. Red/grey theme, works great.
2. Nobody knows your data usage, so it is impossible to tell. As long as you do not use it under Windows (or any other situation in which you'd need the FAT32 partition) there's no chance of overkill since all storage remains available.
Make sure to read up on the data2sd thread itself, because both questions have been answered there already. Without reading, you might get yourself in trouble.

I'm pretty sure the latest data2sd thread states they are using Red/Grey micro SD and even red/gold (for best performance)
red/gold = 95+mb/s performance but they are very expensive and only come in 16gb configs.

This is good news thanks! I can still use the internal storage while using data2SD correct? I will get either a red/gold or a red/gray
depending on the answer to the above question.

check this thread. I've summarized a bit of the info read so far on the full thread.
it seems to me the grey/red sd is the best choice as the transfers seem to cap out at 20mbs for read and half of that for write, which means that regardless you arent going to get much more of an improvement.
However I'm more interested in getting one of these sd cards for Linux as I use my machine as a dev machine.

Yes, the internal storage is mounted as /sdcardi and is fully accessible.

[Q] GT-I9003 + CM10.1A9 (dhiru): its 3.0.8 kernel supports swapping or not?

As in subject. My phone has SwapSD installed (32GB uSD seen as internal memory).
I'd like to use the actual 1.5GB internal memory with Swapper 2 to create a swap space, expanding phone's RAM?
3.0.8 kernel supports memory swapping?
Thanks,
Leonardo.
I think sdSwap is a placebo effect i used time ago and didnt notice any improvement in terms of performance, other thing is Zram included in our 3.0.8 kernels, this is a virtual ram who complements the default ram and i think enabling it can feel a bit of more multitask and performance, for enabling go settings/performance/memory management/enable zram and reboot, to control the swappyness you can use performance control.apk and to see if its working type ( free ) in terminal. Try both methods and decide by yourself, im just only sharing my experience, hope it helps you on your doubts.

Thanks (already thanked with button, too...:good for the answer!
I'm trying zRAM. But I have a question.
In my opinion, SwapSD and Swapper 2 are two completely different apps.
SwapSD is used to swap between phone's internal memory and the MicroSD memory (storage)
Swapper 2 is used to create a swap space (virtual RAM).
So if I want to give a try with Swapper 2, I need to know if 3.0.6 kernel supports RAM swapping... I don't want to brick my SL...

What i want to say with sdswap is what you are trying to do, a partition on sdcard to be used like ram its not the same like sdswap.apk.
Feel free to use swapper2 or other similar apps to do that theres any problem with our kernels i already did it with any problem and any noticeable improvement.
