I am running omega Rom v13.and siyah kernel 1.5.3
I always observe my task manager and observe that my ram usage cannot higher then ~700/833MB?
It kills my apps if usage is higher then that.
I mean why? I should be able to utilize all the ram to right?

You only have this much ram, the phone needs its own ram for graphics, buffers, os etc. You can get more ram from siyah kernel using swap but this has disadvantages

I am not referring to the available ram.
Yes, I know system reserve some of the ram which left around 833MB for user.
and with touch wiz and other background process holds the ram, I see roughly 500/833 left over.
Now the left over is my ram for my advice apps, isn't it?
This is my question now :
The left over ram which around 333MB, I can't utilize all, I can roughly use up to 200 MB, and if over, my apps start killing
.why I can't utilize all of the left over ram?

Android its based on linux which hates to leave memory unused, it therefore uses free memory ssh buffer cache to speed up I/o.
Found this, you can run free -m from a terminal emulator

My question is how do I get more of that RAM for use? Flash 10.1 is taking up quite a bit of memory (for example, when watching video from hulu), and will often crash because it runs out of RAM to use. I remember seeing some kernels that give more RAM to the user. Unfortunately, Nero V3, which I am using, only allows the user 304 MB of RAM and with other background services, the realistic amount free ram is about 180 MB. Can I shut off services or do anyone have recommendation on which kernel gives the most RAM?
I think some of Eugenes kernels allows for a *bit* more memory (maybe 20 mb more). Just look him up on his website.
You could try a more aggressive scheduler using OCLF.

i use GingerClone and i get tons of RAM free.
i have 176 free right now, and i play dungeon defenders, which takes like 300 or something not sure though.
Suggestion:
try using a task killer, it'll free memory, then use the program you want, it'll give more ram?
I'm running dagr8s alpha 2 ics rom. And I know that it has lower ram than the gb roms. But lately I have been running Tasker (amazing app btw) numbers and it keeps notifying me that I have low ram and it might not work properly. I go to applications in settings and check my ram and it says I only have 98mb free. I end all tasks and clear ram and then still I have like 120-130 free. I'm afraid that this is a too low amount. And wanted your opinions on what I should do. Is this enough should I just ignore the warnings will Tasker still run fine? How can I get more ram? Are any of you also experiencing low ram?

Taller uses ram also. I run trebuchet launcher on alpha 2 and have no real issues. If it gets slow you can hold home and clear things out. Running a lot of widgets still affect ram also.

If you go to developer options in settings at the bottom and select the background processes and set it to 3 processes at most that helps alot...also if u change ur dalvik heap to 64 that also helps a ton...DO NOT and I repeat do not set it below 64 as u will soft brick your phone

You must understand how Android uses memory, it loads your frequentlyused programs into ram so when you go to use them, they open much faster than if they would if they had to open "fresh" each time.the lmk (low memory killer) should take care of everything if you ate currently using a process that uses a lot of memory it will kill off apps as it needs to.
Put simply: FREE RAM IS WASTED RAM.
Have a marine navigation program "Navionics USA EAST" that wouldn't open in ICS(leak and Saurom) unless I cleared RAM. No issue onstock GB, and runs fine on sgh-i777 ICS? Tried debloating leak, but didn't help much. Will try limiting running programs when back on ICS.

Free Ram is wasted ram. Never thought about it like that. I understand but i would still like some free ram just so its available for other apps i open. I did use the task manager to kill running apps and clear ram and it didnt free up that much ram that is why i was worried.
Ill try limiting background proccess to .
Also how do i set dalvik heap to 64? And what exactly does this accomplish?
Thanks for the replies guys.
Yes set it to 3 processes at most. Task manaher killers r just crap dnt use them

Welcome to ICS. This is exactly why I DONT like ICS - the memory footprint is huge just for ICS alone.
Free ram is not entirely wasted ram.
Let me explain.
So, my phone RAM is completely (or nearly) filled and I open a new app. There is now a long delay as Android goes to work closing app(s) down and doing garbage collection to free up memory for the new app I just tried to open but it only frees up enough for the one app I just opened.
And now, every app I go to open is going to have this long delay.
What you really want is about 80% ram usage - enough that there is free ram to open new apps without Android having to scurry around to free up a bunch of memory.
I dont know if there is a way to force a certain amount of ram to be free but imo, thats what youd really want.
I only have 6 user apps on my phone and Im running stock GB so even if I opened everything at once, there would be plenty of ram to have them open all at once (Go Launcher, Blue Skies (paid), Battery Power Widget, System Tuner Pro, BeyondPod, & Audible).
It's called "minfree memory," what you want is an app that will allow you to modify those values. Back when I had a Captivate, I used an app called AutoKiller for that purpose. I haven't needed it on the Note though. You can find it in the Android market.
Is it possible for apps to crash when the phone doesnt have enough free memory (RAM)?
-Once you go NOTE, you'd say 4 inches a Joke
How much RAM do you guys have available when running GB. The phone only sees 767Mb of RAM out of the 1Gb is that normal?
yea i think thats normal because the phone system uses some of that ram to make the phone work. Like if you ever had a sd card or an ipod that was say an 8gb ipod you actually only have like 7.66gb free.
But yeah I would like more ram availabe so the phone can load apps quickly and wont have to waste time closing stuff. I dont think free ram is wasted ram
As said before, Android uses ram differently since it based upon Linux. If the entire ROM runs around 600-800mB and most of it gets loaded into RAM, this will leave you with 400-200mB free RAM but the entire OS is already loaded and ready to go! Once you load a RAM intensive application, Android/Linux kernel will free space for that application.
I believe GPU consumes an excess of RAM to handle this beast's resolution/size.
I have to go back to GB. Delay in apps opening is getting old compared to i777 daily driver.

Hi pls is their anyone who could fix the high ram usage a mod or something?
Sent from my GT-I9300 using xda app-developers app
What do you exactly think ram is, or "high ram usage"?
What are you expecting to be fixed?
This phone has plenty of ram, stop looking at the numbers and thinking your too high, don't listen to anyone that tells you that you need to kill tasks to make the phone better, they are all wrong!
Android works on a linux kernel, its not like windows and does not slow down (noticeably) when you multi-task, it manages its ram usage, it caches processes to save you time and battery next time. When it's ram is truly full (which I doubt yours ever is) it kills it's own apps.
So in summary unless android is closing all your apps when your trying to use them, stop worrying about ram!
/rant
Please everyone stop saying that Windows does not use the RAM for Cache.
Just because it doesn't show the values in Task Manager doesn't mean it isn't doing so. The Resource Monitor tells otherwise.
port76, if you're rooted you can throw out all the apps that you do not use (e.g. the whole Samsung-Cloud stuff, Samsung Accounts, AllShare, ...) which will give you several MB more of RAM available for caching.
For the rest, refer to this: http://www.linuxatemyram.com/

ram usage is fine on the S3, theres no fix needed.
unused ram = useless ram
if ur S3 lags, it must be something else

I would rather have a fix for the redrawing of my launcher...
When i'm browsing and go back to the launcher it redraws/restarts...
Because other launchers beside touchwiz are not locked in the memory...

Hello,
I have 3 questions if you may help:
1. how do I close an application? for example in the iphone i would just open the running apps and close it by long click - here I dont get it? for example if I listen to a radio and then i clean the application on the task manager the radio keeps playing....
2. The follow up question will be what is the best task manager on android?
3. Ram issues - I understand that 1gb ram is more than enough - however on the task managr it shows me maximum of 280 mb free on the ram - is it normal? or im doing something wrong??
Thanks!!!
The best task manager is none. Android uses ram in a totally diffrent way to IOS and windows. Android keeps most of it's free ram engaged, this way it can access and allocate ram much faster than how ios handles free ram. All you need to know is, on android, the less fee ram you have, the smoother things will be.

At the time of writing this, I have 89MB free and the phone is still wicked fast. No lags or anything.
So, you do not need to worry about memory management in android now. It knows how to take care of itself.

Disable Ripple Effect and then disable Lock Screen. Voila! You gain over 100MB in RAM.
Or leave as is. Not sure why folk get hung up on free RAM. Android is quite grown up now and can look after itself.
You have plenty - go and enjoy your phone.
Yes it is a problem
Hi bro!
Of course it is a problem!
Who tells you otherwise is either ignorant or playing idiot just to convince himself that everything is alright.
I have done quite a scientific comparison with numbers and everything; look here: http://forum.xda-developers.com/showthread.php?t=2141721&highlight=ram+discussion
EDIT: And yes I cannot multitask as I do on an S2!!! Something is seriously utterly dangerously wrong with this damn phone!!!

The multitasking would be better with 2gb of ram but the phone is still perfectly usable with 1gb.
The galaxy s4 will inevitably have 2gb, just wait until it releases if it's that big of a deal to you.
I can send text messages, make calls and look at porn just fine with 1 gb of ram so I don't feel your pain.

As others have mentioned, this is pretty good for an S3. Still not enough for real multitasking but hey, if you run 1 app, it will run wicked fast!

I had my lockscreen disabled already and had to re enable it to disable ripple effect. Then after disabling lock screen again, sure enough I gained 100 more ram. Nice tip

Please stop misrepresenting a microsoft quote in the same way every idiot does on the internet.
Free ram is ram that can be utilised for standby caching and making app starts faster - This is the way microsoft intended this statement to be taken. This "standby RAM" (Cached in task manager) is ready to be released and fill with application data on demand without making other applications page fault.
Ram being utilised by excessively hungry applications is more paging, more thrashing and less performance.
Ram in use by hungry droid apps falls in the latter category.

And your a fool for thinking Android memory management is like windows memory management.
When RAM starts to fill up in android background processes are cached to the cache partition and because we aren't using a HDD the performance loss is negligible.

Free ram is wasted ram for android and Linux. Only in windoze free ram is good ram.

It is a real problem.
I think CM10.1 has more free RAM.
Except when apps in Android are cached they often have to reload when you "switch " back to them. Not really multitasking. It's as if when the app is cached it stores a pointer to what it was doing. I notice a huge difference when I have 400mb free ram, if I only load a few apps they don't get cached and I can switch to them without them reloading. When I have less than 100mb free ram even my desktop gets redrawn, tabling chrome reload etc etc

You sir, are talking out your arse.
When ram fills up on android, processes are either terminated leading to them having to be restarted or pulled from cache, leading to sluggish ui and loading.
