I guess its okay to use swap. Swap increases your ram and so you can preform better multitasks.
I think the con is that the phone gets slow if your SD card is not good. But i am really not sure on this one

SWAP expands your RAM, so when you have it, you can open more apps than than you could without it.
If You're not trying to run many RAM-eating apps at the same time, you're only wasting your SD space.
I close every app i don't need, so SWAP i useless for me. Also i'm using Dorimanx ROM, which when SWAP is enabled has no built in task manager. If it wasnt like that, i would probably have it, just in case.
About slowing phone down: SWAP will never work as fast as RAM, since it has slower access time than native RAM. It's just to keep everything going even if you ran out of RAM, maybe a little slower, but still.

Available Memory

So when im not running anything, when i open Advanced Task Killer it has like 125M is this right???
So what the other 387MB doing?
what I see
when I 1st start I have about 230MB, after a few minutes it goes down to about 90mb...without opening anything...seems many programs on the Samsung "open" by themselves...also, I see that the CPU goes down to about 100Mhz so I keep it at 1000Mhz with setcpu....plus deleted many Samsung apps(about 30MB)...helps with the lag...
Don't worry so much about it. This isn't windows, you don't need to worry about free RAM. Android will kill tasks as needed to free ram when it needs to. Some of that is likely used for disk cache as well. That will also be released as needed. Let the OS do its job, it's quite good at it..
Killing some of the bloatware will help as well, but you need root.
I also think that this phone, like the G1, has some of the speced 512M ram dedicated to the camera, GPU, and other stuff. In the terminal, free shows about 388M as total ram.
is it a good to create a swap partition on the SD card?
Why on earth would you want swap with this much ram? You likely can, with root and swapper, but why? This phone doesn't need it like the G1 did. Swap could help keep more apps open in the background, but there are already a lot of them there. I don't see any benefit to swap right now. What isn't working for you that you think is related to low ram?

As with the nexus one, not all 512mb can be addressed by the system right off the bat; we may need to wait until a newer kernel comes out

How to add more ram to our tiny devices(Through SD card;) )

http://forum.xda-developers.com/showthread.php?t=683123
How to use Swap space on SD to increase ram on our devices so we can run more demanding apps.
swap is possible only with custom kernel, so it will not work for us
I believe that doixanh proved more than enough that custom kernel is not needed for any kernel modifications Still, we would need a module.
but i don't think that he should make swap module it will be better if he will finish this
Well, it's up to him what he wishes to develop
IMO swap is useless for Android. It has its own memory management already.
And it would certainly take a high class sd card, AND it would be harmful for it So next time we should just buy a phone with bigger RAM memory

So, how can we increase the memory through SD, my finding isn't good ? If not, how to do it the right way?XD

I don't really care about my SD card's health XD i just want more ram XD
But what do you need slow RAM for? RAM is very dynamic and since we already use app2sd it could even slow your device down instead of enhancing performance...
EDIT: Well, maybe it would be faster if you have a class 10 card...
Yeah SD is slow and putting swap there will be incredibly slow.

Yes, but i want this because you know that there are some applications that won't run on X8 because of it's low ram...so, i dont care about about speed, also, i don't use app2sd, so no slowdown, I am using Class 4 card
Yeah I know. Just my opinion
doixanh said:

So, is there a way of using ram just for the ram consuming apps, to make X8 able to at least run them? (You already released an SD card speed fix, so it should go a bit faster...Can you help me, cuz i really like running RAM hungry apps and i don't have enough ram :|
No I don't know about that. Haven't tried swap thingies yet
for example, there are games, like dungeon defenders that requires 256 MB of RAM at the runtime (it's the requirement of unreal enginge 3 i belive). some guys have managed to run the game on LG swift, which is pretty much the same device as x8 when it comes to hardware. maybe it's not running too fast (although i saw some video where it was even faster than on some more powerful devices), and it's not quite playable, but some people might still enjoy it. and without SWAP, it's impossible; and it's just a one example.

Thanks for supporting my ideea XD We really need Swap for Ram Hungry apps
Yes. great. ideA. but... is posible?
The app that does this on market requires custom kernel so might not be possible atm

RAM

I have rooted my Asus TF, Put on the H 3.1 os, used Clemsyn Blades kernel, running very nicely. I have rooted it, and uninstalled crap like facebook, books, splashtop etc...lot of useless bloatware is out...However here is the problem........LOW MEMORY....This machine has ram of 1GB, and only 800mb shows, so almost 200 for the GI, and out of that 800, about 400mb is always used, despite using various app killers, I think we should be able to get it to about 200mb used? anyone know where so much of ram is bieng eaten
My question to you great knowledgeable friends is;
1) how to get rid of more useless apps eating memory
2) does using a different launcher reduce ram eating?
3) is it possible to achieve about 200-300mb consistent ram?
This is an awsome machine, I think more tweks we can make is super. I have a Samsung GS2, I have removed most of the stock stuff on it and set up my ownlauncher etc. It runs with amazing memory, 500mb free, and awsome graphics interface. Less nonsense.

If you haven't done so already you could use Titanium Backup to remove more stuff (including system apps) since you're rooted. I would advise caution however in case you remove the wrong thing. Perhaps someone else can post regarding which particular system apps are safe to remove, as I haven't expreimented with this myself.

Ive done that and removed about 10 items. Its running well at 1.4GHz but only problem too much ram usage.

He could just freeze them first and play with the tf a couple of days and if there are no problems, delete them.
Removing junk isn't a bad thing to do, but in my experience, app killers do more bad than good in android. Other than in windows, you don't need tons of free ram to run apps smoothly. Android has a great ram management that fills your ram with apps for fast access, and closes the least used/needed when another app requests more ram. So if you use an app killer, your tf will have more to do with restarting the apps you just closed and your performance will actually decrease. Google it and you'll know what I mean.

As i said before, much ram usage isn't necessarily a bad thing. It only eats performance if a running app is badly coded and doesn't give its ram free when required. Then you better kill this specific app instead of autokilling stuff. Well coded apps won't eat your performance, no matter how much ram is used.

300Mb oof ram are dedicated to Nvidia Tegra 2. For this reason you read "only" 700Mb. Maybe in near future we will able to allocate more memory than 256Mb to our Tegra 2
memory usage doesn't mean too much now if the app/programe is properly coded, when needed, android should be able to release them on the fly......
same goes to my windows 7 machine, it's got 8 gig memory but the free memory always remains under 500M because the system is using them to cache most recently used applications.
Constantly clearing memory will not help too much, and believe or not, it worsens both the performance and the battery life..
but again, android is not as robust as windows in the terms of memory management, so it's not a bad idea to occasionally take a look at the actual memory usage but just don't go too excessive...
Screwing around with app-killers is never a good idea. Are you actually experiencing issues due to insufficient RAM? I've never had an issue with RAM on my Transformer. Android is much better at handling its memory than people are, let it do its thing.
And for the record, RAM is there to be used. It's the fastest memory a device has, so the more it makes use of, the better. If something else needs more RAM, Android will flush out something that doesn't need it.
I think app-killers are one of the biggest issues with Android, in that people seem to think they're necessary. Unless you actually have some app that's misbehaving or has a memory-leak or something, you shouldn't ever really need to manage your running applications. Just leave it all alone for a while and see how you go.

Perfectly said. Don't mess your Transformer around with "Task Manager"-type apps.

not at all. The machine is fast, its very quick and loads things quickly. The only time I had problem is using logmein, it crashed and said out of memory...I was a bit perplexed. I cleared a lot on my SGS2, and it was much faster.
Let me know any ideas, otherwise, as suggested, I will see how it goes
From my previous experience with Android devices, it's nearly impossible to increase the amount of free ram. I've tried, and only found one solution that I'll talk about later.
This isn't a bad thing. Ram is not CPU usage, and ram is going to use roughly the same amount of electricity regardless.
What android does is fill up the ram with programs that you will potentially use. That way when you want to use the program, it's already loaded in memory. When you load another program into memory, say a game, it will close apps to make room for the new app.
If you really want more memory, the closest thing is a swap file or partition. I use one on my phone, and it helps a good bit. Don't know if it would help the TF101, since it already has 1GB ram.
If you are still set on more free ram, try a program like auto memory manager (there is also another program very similar, has a blue fish for a logo but I forget the name). This doesn't kill apps in memory. Instead it changes the the when android closes programs in memory based on how much free memory is available and the priority of the program. I used it before on my phone with pretty good success, but now I use a swap file instead.
Right now I don't use a swap file or memory manager on my tf101, sine it runs great without it.
Thanks for all your responses.
I think this article should explain how Android 2.x operates. Even though the article is not about Honeycomb (Android 3.x), I doubt Google has changed how it manages memory in Honeycomb.

There are some benefits to SWAP yes, however using your MicroSD as RAM is far far slower than using actual RAM - so some things can play a little badly with it.
It also isn't a healthy thing to use when it comes to prolonging the lifespan of your MicroSD card as its using all those writes at an almost constant rate.
That being said though, enabling a SWAP partition on your MicroSD card is a somewhat easy thing to do and there are loads of other apps that will do this for free for you. I would not pay for this.
me tried in all roms me use my memory class 10 and good swap for me

So what your saying is it would let me have more multitasking but at the same time it would be slower.
First here is how to do that for free.

And yes I use that method, for me my Neo2Play gained some speed, less lags. But there is but, best is when used with fast card. I have 32GB class 10, on my old class 2 it wasn't so impressive.
Works great for me with 1105 MB swap RAM on Atomic GB 7.0.(2.3.7) Especially when using it with RAM Manager Pro on Hard Multitasking setting.

Lg d722 ram expansion? [howto]

Greetings fellow persons
I have a LG D722 and I wish to breathe some new life into this phone
I have heard that you can expand ram with the use of an sd card
Here are my questions
Does my phone support such a function?
IF root is needed, will it still work after i disable root?
Do i just get a 10 speed XXGB sd card?
What would be the best sd card to choose in terms of speed (that the phone supports)
What (free) app should i use?
If you need any additional info, let me know
Thanks

This is not possible. Even if it was possible, it would be way too slow because ram is way faster than an sd-card.
EDIT: You can use a SWAP file, but you can't use it as "Real" ram

A pity that it is not possible, the phone has a rather low amount of ram for today's standards
I see that you have also owned a G3 albeit another version.
Did you make any changes to improve the phone performance?

I had the "real" g3 with the snapdragon 801 and 3gb of ram so I didn't had to do anything because it was a great phone for the price.
But, before that I had a really bad phone with only 512 mb of ram and I tried everything to make it go faster (overclock (witch make the phone really hot), "ram booster" kind of app (they don't make any noticeable difference), etc...) but I realised that we just can't do that. So, unfortunately, we have to live with it until we change phone.
That being said, you can always disable animation to help the device go faster but that's pretty much it.
Yep done that it helped a bit
I am using "root booster" it makes my device react quicker then normal, i noticed the difference right of the bat
And got rid of some of the bloatware, am currently researching which other ones i can safely remove
