So does this still ruin your sd card faster than normal like swapper did?
How much faster?

Technically correct answer - Yes, it will ruin your card much faster than normal.
Real world answer - You're talking about lifespans in the single digit years rather than double digit years. Modern flash memory can handle insane numbers of writes and the onboard controllers automatically spread data out to keep the wear even. Also, error correction on the card will simply disable worn out bits and keep running on the rest.
Simply put - use the heck out of the card. If you haven't upgraded it, in a few years you'll start loosing capacity, a few bits at a time. I wouldn't worry about it.

Alot faster if you're using a hero ROM. We're talking about 2 good years of usage with the SD card running swapper.

It depends on the ROM and how you use the phone.. I use CM and I haven't really seen any speedup with a swap. What it does for me is keep my browser in memory longer when I switch out to do something else quick (reply to a text, for instance). On the other hand, it sounds like Hero users almost need a swap to make the system usable.. Just depends on what ROM you use and how you use it.

[Q] Low available Ram !!!

Hey Guys ... Did you look to the Ram status in the Galaxy Note ???
I have 600+/800 usage in normal situations !!! and when I clear ram it reached to 400+ which goes back to more than 600 Mb after moderate usage !!! what about in your Notes guys ??? Any solution for this ?? plz comments ....

What is it you are planning on doing with the free ram? Has the use of ram caused any problems? Don't worry about it and use the device. There is no point in trying to worry about something which is being used or not being used which is not affecting you in any way. Until it does have fun with the phone.

Do you think Android is running on air? The Note has 1GB RAM which the OS takes 200MB at boot. The rest is used by apps and other things. If you're not going to use the RAM, then why do you need it?
"My computer uses 50MB of RAM, And i have 32GB of it!" WHAT'S THE POINT?!

Try RAM Manager by Juwe. Be aware that the more memory you free up the worse multitasking will be.

Are you kidding me? Use RAM Manager when your device has 1GB of it? Please slap me as hard as you can.

This thread needs to be deleted.
RAM is there to be used.
I would use 100% of my RAM 100% of the time if I could. If it's not being used, it's being wasted.

Unused RAM is totally wasted. When 2GB devices come out OMG my device is using 1GB out of my 2GB!!!

To each his own, who are you to tell others what to do with their RAM? I'm not your typical "as much free memory as possible freak" but how comes that when I kill some apps before running something more intensive it's usually smoother and performs better?

I've never had to manually kill apps with my G-Note, so I dont know what your doing wrong, Could be a faulty device as far as I can tell.

Thanks for your advice, I'm running to get it replaced.

600mb usage is totally normal on moderate use. Obviously you don't know how RAM Management work on Android. Go and replace your phone but nothing will change.

Would you replace your computer because it's using to much RAM?
Chances are you would find the RAM hog and keep it from starting up when not neccesary.
600mb is normal usage.... if you are not happy with that high of usage delete the apps that have services running or are always in the background. Android does this for you as you approach full RAM usage anyways though...

Ever heard of irony?
Of course I'm not gonna get it replaced I'm happy with the way it is.
Yes, I've read about Android memory management quite a while ago. Very smart and very convincing. Now on the other hand - every now and then after some intense moments - let's say I'm driving and I'm using offline satnav then online satnav then there is a phonecall, then I make a voice note, I get out, send a text, use my GTD app and whatever else - after hours of such use when I get home, stretch my legs and I fancy to play let's say Galaxy on Fire 2, I find it smoother and less likely to crash if I just press "kill all apps" button in Task Manager. And since I installed RAM Manager I don't have to do it. And I haven't noticed any side effects that would interfere with my style of using my phone.
So guess what - I really don't give a **** about Android memory management and all expert opinions because I know what works for me and I'm happy with that state of things.

I posted in this thread beacuse another user complained about the problem that I came across and found solution to. It's certainly not the best one, but it's the one that works for me.
In the meantime I got ridiculed by more social-oriented users who need to accept and be accepted. To which I got upset and posted some crap. As a result I hijacked the thread. I apologize and shut up.

Samsung makes us fool it has only 800MB RAM. Even i thought it was 1GB.

It has 1GB. 200MB is reserved for the system.

Memory usage
My daughter started a game where a photo is used in the programme, and I got the message "Free RAM low, resolution of photo reduced". Had to kill running services to be able to run it without the reduced resolution. Checked the overall Galaxy Note ram usage and just out of the box I have around 230mb free of RAM, I have an HTC Desire HD (768 ram) that has the same free and it is filled with running apps. When you get that kind of messages from a new phone, from some ****ty simple kid programme before I have even filled it up with stuff I get really annoyed. When I kill all I can i can get max up to 400mb.

Yup, TouchWiz is a greedy RAM eating whore. Wait for CM9 and then you'll see why custom UIs like TouchWiz and Sense is bull****.

Well, you can use a swap partition. CM7+ also has ram compression.

For me Ramexpander say is not compatible with Ace.

I heard swapping partition from sd card to increase the ram, sd card might get damaged!!, is it true?

Reduces SD Life so yes.
Sent from my iPhone

but i guess you will change your sd card before it gets damaged so much, that you will notice.
i only had this once on a USB pendrive. it loses data since some weeks ago. but its about 8 years old.
lets say that todays SD cards have better lifetime than years old USB sticks. lets also say that you use your sd card more often than i used this stick (backups later car-radio). so we can say your SD card might have a bit less lifetime. lets say 6 years. in 6 years you will (most likely) have a new phone, sd cards are "oldies" and if not, 1TB cards are state-of-the-art.
so....yes you loose lifetime but i dont think you will use it till it "dies"

It really depends on use. When I swapped i ate through my sdcard in less than 6 months.. so there you go. Keeping low swappinness will increase sd card life, but it does depend on use.

increasing ram by swapping sd card is effective to what extent...can any body tell me....does it bridge the gap of our low ram...

That why the requirement need class 10 SDcard

You can use CM7 that uses less RAM!.. I just went from CM10 to CM7 and it really is an improvement for ACE as it uses a bit less RAM and that is noticeable.

thanx but no cm7

there are quite a few apps for increasing the ram like ramexpander and swapper...
but before using these apps remember that the read and write speed of sd card(which is secondary storage) is vey less as compared to that of the internal ram.. and probably thats why ram is very expensive as compared to sd card...
so if you use these apps may take a bit longer to start and even the best of sd cards i.e. the class 10 one won't last longer than 6 months...

Increasing ram
Hi i install ram manager pro apk on gts5830i then i create a swap file 128mb using this apk, then on sd card i see swap file img does it mean my phone ram increased.... i didn't install any kernel for it... plz does tell me if it increase ram or not...

I tried something on a other phone from my neighbor. is a huawei with same specs than the galaxy ace..
I moved apps to SD card with link2SD and created a Swap file in the internal storage.
The internal storage is much faster than the SD card and much better for swap file.

What is RAM
Random Access Memory (RAM) is temporary data storage that the CPU uses during calculations. The more RAM a device has, the more calculated results the CPU can store - which means less time the CPU has to do the same thing over and over again. In other words, the CPU can check RAM to see if it has already made a particular calculation in the recent past. If it has, it can use the pre-computed results instead of wasting processing time recomputing the same calculation. In short, more RAM means a more efficient (and faster) device.
SWAP
What is SWAP
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

[Q] how to free more ram

hi everyone i want to know how to free more ram in stock rom when i restart its almost 700mb ram usage and after normal use its goes to 1200mb but i want free memory like my nexus 4 which use ram 350mb to 700mb max please help me guys

My RAM usage is about that high, 700mb. But since the Z1 has about 1.6 gb of RAM, you shouldn't really worry. If it does get to the point where apps stop working or services become unresponsive, restart the phone or kill the app that's using the RAM. I believe when your RAM usage is about 1.5 GB it starts becoming a bit unresponsive.
Nexus uses less RAM because it only has stock apps. Sony has their own software running in the background along with some of Google's apps.

That doesn't makes sense. As long as your device isn't unresponsive or laggy you shouldn't bother about RAM-Usage. Android handles your available Memory quite well.
Try looking at it like this:
There isn't any use in having more and more RAM, if people on the other hand go and try to keep the RAM-usage low. As long as you don't have problems (lags or such) having free RAM is just eyecandy.
Additionally:
For every app killed, Android needs to load it from storage the next time, resulting in more battery drain than just letting it idle in memory

My phone is a RAM eater?

Hello,
I have my P9 now for a month or so and i really think it is a RAM eater, it sucks up my RAM.
It has 800mb's free ram when all i repeat all applications are closed that is not how it supposed to be i think so.
after i reboot my P9 it has 1.69GB free but after a day or so the same thing happens is this normal or not?
BTW i have the 3GB model EVA-L09

Hmm.. I have the same model too and I seem to drift at around 1.2~1.6 free most of the time unless I'm heavily multi-tasking, do you have any heavy apps that maybe auto-start or anything like that? You could also try factory resetting if it's going that bad.

It's not a problem, its memory management.
There's no point having lots of ram with nothing in it.

If there is lag and you feel it's RAM related, there is a "clean up" function in phone manager. Or just kill some apps from multitask view But most of the time there really are almost no benefits to having free ram on android. RAM performance is not scaling with the amount, like CPUs for example. It's more like, you have enough then you can run the apps, you don't have enough then you can't run it. But on android that's basically a non-issue because it will automatically clear the ram if you don't have enough for a certain task.

I get around 1.5-1.7 when freeing memory. I don't have a lot of apps installed though. It doesn't go down even after a few days withoit restarts unlike my older phones.

If you are having a lag issue, there is a setting for 'protected applications'... in advanced, battery manager...may have a look there, and un-protect some.
