extra tips
Mods like crossbreeder also can make CM7 little fast.
you can share your SD card space with RAM, with Swapper, search XDA for more details.
V6 supercharger is also known as great script for increasing ram usage efficiency.
hope this info helps. you'll find more information if you read around XDA.
Ty for the info just 2 more things how to get crossbreeder and how to use swapper please tell me what's good for swapper ty again for making my wildfire run smooth and the battery is fabulous keep up the good work

I've made a thread about crossbreeder in the themes and apps section, check that out.
Get the crossbreeder Zip files and flash it in CWM recovery. That's it.
Now about swapper,
Android system usually caches apps that it thinks the user would use. That results in faster app opening times and better multitasking, because the apps are already loaded into the RAM.
But when the RAM gets low system clears out cached apps to make space for foreground apps, this is where swapper comes in.
Swapper uses a partition on sdcard (if you have a swap partition),or a file in the sdcard to act as an extended RAM. (sort of )
So, now when the RAM gets low swapper moves some cached data to the sdcard, and frees up space.
So instead of totally killing an cached app, the app still stay cached in the swap file, until its open. Then the data is moved back to RAM.
By the way, swapping will DECREASE the life of your sdcard.
Swapping is not necessary, unless you're into heavy multitasking
Tip - if you have terminal emulator installed, type free and enter, to see the RAM usage

I'm asking because I'm frequently out of RAM, causing extreme lags and launcher reboots. I know the CPU reserves 300MB, leaving 700MB, but how much do ROMs typically occupy? Any recommendation for leaner ROMs? Or perhaps there are modifications to enable more aggressive task killing (non-background tasks)?

Run out of RAM? never again with this Mod
Gnex Supported! :good::good::good:
http://forum.xda-developers.com/showthread.php?t=2145133
How would that work since my GNex doesn't have an SD card? Isn't everything on the same internal memory?

First of all, that mod puts it in /system, /data and/or /cache. So it doesn't even try to use the sd card regardless.
Second, I just thought i would try it out and it throws out an error "incompatible with your device Galaxy Nexus (toro).
I figured maybe i would give swapper 2 a go again. It hasn't been updated in ages, but it seems to work. You can leave it on sdcard (which is just internal memory anyway) or change the directory to any you want. I changed mine to /cache since my sdcard is kind of full. Can even change the swapiness within the app. Only downside is the limit for it is 256mb. So far it seems to be working properly on Verizon Galaxy Nexus stock, rooted, 4.1.1 with lean kernel.

I have done some tinkering. What seems to work for me is limiting background processes to 4 or less. These turn out to be cached processes which keep opened apps open. They eat up your remaining RAM and should ideally be removed if an app you're trying to run demands it. However, the removal process causes significant lag, possibly due to the slow internal memory the GNex has.
I'm running CM10 (4.1.2), and I have 245MB free right now. It has gone down to as low as 150MB, but rarely below. When using 4.2.2 based roms, I get as low as 40-50MB, which causes problems. I don't have high hopes for 4.3 right now.
I have been trying to figure out why the Note has so little of the 3 gb of ram available at any given time. After a fresh boot, I might have 1.3 - 1.5 available, but that quickly disappears.
I have frozen all unnecessary apps with Titanium Backup, yet after launching just a few apps, I'll be down to 300 mb or so. Looking at the active applications list in task manager, the apps listed are nowhere near to adding up to over a gb of ram.
Tablet seems to be performing fine, I'd just like to know where the ram is going and why. Especially when tablets with 2 gb of ram seem to have much more free at any given time.

i am with you on this issue. would like to find out for my self as well! constantly having to clear ram.
youtube, gmail, and browers = 2.1 gb / 3 gb ...
what the heck?
i constantly have to go back and clear apps, this is such a let down because my htc one could load much more than this, and every1 knows, htc one is no where near the spec of note 2014..
I'm not rooted but I noticed the same thing with the ram, I thought rooting and freezing some Samsung apps, specially Knox stuff, would free up a lot of ram. I'm starting to think that it's not a big deal and Android frees up ram as needed before it starts to get laggy (of course it's not perfect). I think lag issues are somewhere else and not so much in freeing up more ram. Don't you feel anyway that your note is a lot faster after rooting and freezing those apps? As far as I know most rooted users feel that way...(?)

I have rooted mine about two weeks ago then froze all sort of junk listed in here and some other I identified mysefl. Now my used ram remains around 500 clean and around 700-800 when I open few apps. So guys the secret is getting a lot of useless apps frozen especially knox stuff.

Android is based on Linux. Android and Linux both run better when they use as much ram as possible. If you Google Android ram usage you can find a couple of interesting articles about this.

Yup, stuff is kept in the RAM as much as possible to increase performance. As soon as an app requires more RAM than is available, the system moves apps from the RAM as required. Clearing the RAM only increases the time it takes to start an app next time.
I would be disappointed if its NOT beeing used...

People are used to Windows needing free ram and do realize that Linux is a completely different animal altogether.
Here is the article for those that want to understand the ram usage.

http://www.linuxatemyram.com/
Okay, guys. Disclaimer: I'm an IT professional and the Mobility expert for my company. I know how the RAM is used and why. I'm just curious as to what is using it. Especially in comparison to the Nexus 10, which has 2/3 of the RAM and has approximately the same amount available at any given time.
I wasn't looking for assurance that this is how it's supposed to work. I'm curious as to what you guys think is actually filling it up. Since I have disabled most unnecessary processes and only run a few apps at any given time, I can't see why so little is free.

The objective of good android RAM management is to keep RAM full of the the highest priority apps. This enables faster and smoother response. The apps that are in RAM on your device will be different than on someone else's device. If you are curious about how android decides what put in RAM and what to take out, do a google search on "android process lifecycle"
if you're concerned about ram usage go to dev settings and change the "Limit background processes" to something more you liking.
Hello there
I have just bought a Samsung Galaxy Note 10.1 2014 tablet. But it consumes too much ram.
This causes instability and excessive battery usage.
Do I have any chance about this?
Thanks
Android isn't compareable to windows in ram usage. Your tab will run smoother if 1gig is used instead of 600mb, because some data is still in the memory which means faster app starts...
If android needs more ram it cleans the memory itself
Then it's something you installed, because out of the box it's fine.

How did you make that connection?
There are multiple posts here about RAM usage on this tablet and many more about RAM usage in Android. You don't need to worry about your RAM, OS does a good job managing it.
Hi again
I Use "Clean Master" to montior my RAM usage and it always shows ram usage is around 92%
I didn't install too much stuff. A couple of games which I play rarely and a few drawing apps.

IMHO a memory monitor could mess up with normal memory management, because if it is set to a too restrictive policy it could try to free memory that OS will reuse at once, and so on.
I would suggest trying to use your tablet without the memory monitor, then compare the behavior.
How does used ram cause battery drain? It does not. What causes battery drain is when your cpu is getting used. When your apps aren't precached your cpu will have to work a bit harder every time you start an app. Also your memory monitoring app will use more cpu cycles than it will save you. What you could look out for are apps that consume lots of cpu power. Sometimes apps are badly coded and consume lots of power. Those kinds of apps will most likely show up in the battery stats in the settings menu. No external apps are needed. They usually cause more harm then good.

Yes maybe you are right. I managed to improved battery life. But I can't say the same for RAM usage.
Compared to my Sony Xperia Z1, Samsung Galaxy Note 10.1 2014 responds real slow. Although it has more RAM. (2GB vs 3 GB)
I did a research about speeding up it. But couldn't come up with a sollution.
More ram doesn't really make a device faster. Nowadays it's a lot more about the software and drivers etc.. Samsung sometimes neglects that and focuses on adding software stuff that they can advertise. I wrote a guide on speeding the device up. It assumes you have root, but you can just see how many apps you can disable in the settings. Might be enough.
After applying all the steps and keeping my device clean it's the fastest tablet I ever had in my hands.

More ram usage is a sign of more services running.... which means there is loads of stuff running in your background..
If I dont run a single app my ram has 1.3 Gig ram left... go to application manager and check whats running... if you see stuff you dont need freeze it with titanium backup.. or unistall if you are sure its not needed.. your system does not simply use more ram randomly...

RAM is there to be used. Free RAM is useless RAM. The more RAM it's using, the lower the battery usage because it doesn't have to go to flash memory for data.

Like he says when it comes to Linux the more ram in use the better.

I found the problem. It is TouchWiz.
After disabling it and installing a new launcher, Nova Prime, I have no ram and lag issues.
Yes I agree about ram thing but with a huge amount of ram usage multi-tasking is not efficent.
Been running Nova Prime with Lag for several months, still lags. Disable the card reduces the lag a bit. That though is not an option.

After freezing TouchWiz via Rom Toolbox. My device became a '14 Ferrari from a '68 Beatle
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?
