[Q] Memory (RAM) usage confusion

I have two Task Managers installed: "System Panel" and "Advanced Task Manager"
When I use the above two apps to check my free memory (RAM) available, it always shows around 75-100 mb remaining
When I use the stock app manager to check free memory, the value is always significantly higher - like 140-160 mb.
Does anyone know why there is discrepancy between the two readings? Which one shows the more accurate value?

i dont know why there would be a discrepancy but you shouldnt use a task manager/killer on android 2.2+

Starting in Froyo, Android has become more efficient at it's own native memory management than past versions and Gingerbread continued that improvement. What this means is that if Android starts running low on RAM, it will start killing things itself and reclaiming/reallocating the memory without the need for a third party app. The other concern about using a TasKiller most people raise is that if you set it to autokill, system apps or other sort of apps that need to be run(such as Facebook widget, other kind of widgets, noLED, et al) will relaunch on their own causing the TasKiller to kill it again... relaunch... kill... relaunch... kill keep your CPU cycles at 100% and draining your battery quicker than it should be.
That being said, I still use a TasKiller on autokill with the screen off simply because I like to (and paid for the app, so dangit, I'm gonna use it! ). Once you have identified the apps that relaunch upon kill and set TasKiller to ignore them, the battery concern isn't an issue.

they changed the way android 2.2+ handles apps in the background so when the task killer kills an app it does more harm than good, mainly kill the hell out of your battery because android wants to start it back up again
Dont know the details but thats the jist of it

System panel is a must have. It's not used to kill all apps, just to monitor your phone and kill an out of control app.
To answer the question, the way android shares RAM between processes is very difficult to actually identify free RAM and which apps are using what. So some apps make the choice to display the free RAM differently, no way around it as there is no one "right answer" on each memory usage. I always go by system panel myself.

Whats Best way to free up the ram???

Whats best way to free up the more ram? I have root and froze the safe stuff. The lowest I can get free is about 185MB / 328MB.

Rooting and freezing apps doesn't give you more RAM, since there is only 512MB of RAM and the OS takes part of that to run.
You can free up internal app storage space, by deleting bloatware, or cut/paste the bloatware into a folder on the SDcard (I call mine VZWBloat) and that will save you space.
You can run a task killer to kill off apps that you don't need but you have to be careful, Android does need certain apps to be available in the background and it will just reopen automatically and that will put them into a cycle and drain the battery.

Freeing up that much RAM is probably detrimental to the overall efficacy of the memory management system, I've never seen mine at 185MB, and if I did I'd worry something was wrong.
If you really want to free up more RAM, for no benefit whatsoever, use something like Advanced Task Killer and set it to allow killing of the lowest level processes it can, then kill everything. Bam, tons of free'd up RAM. Again, this has pretty much no benefit whatsoever and for a short time will probably make your phone more sluggish and slow.

In Android (Linux) free memory is considered wasted memory.
That said, I remember on my galaxy S that the phone ran snappier when I tweaked the memory management of the phone.
Task killers are generally considered a bad idea on android, so I would avoid using one of them to free up memory. However, there is a poorly named app called auto killer that is actually just an interface to tweaking androids built and memory management. I recommend giving it a try, here's a link: http://market.android.com/details?id=com.rs.autokiller
Note that it is not a task killer per se, it is just a tweak for android phone memory management schemes.
I haven't used it on my droid charge yet, but play with the settings maybe starting with aggressive. Good luck and let us know how it works for you.

I don't have my phone with me right now, but you need to make the folder read/write and then hit menu and multi-select or select multiple. This thread http://forum.xda-developers.com/showthread.php?t=1082588 shows what is ok to freeze, but I am not familiar enough with those to say you can remove all of them. Typically I would look for the Verizon specific apps, games like lets gold, guitar hero etc. If you remove anything related to touch wiz (widgets) you need to remove both of the associated files. I am pulling this from memory on my previous TB.
These are the ones I recognize, but the others in that long list I would like to see better clarification of what they are and how they are tied into the TouchWiz UI so we don't get errors. Please exercise caution when doing this.

BY FAR.... BAR NONE.... The best way to free up memory and keep it free without messing with task killers is to use a program called startup auditor. This app prevents apps from starting up automatically on startup and throughtout the day without interfering with normal app processes. You can shut down or enable any app you want.
Even cooler, if you select the option menu and hit disable all, it only disables programs that won't interfere with the phone operation so it knows which apk's are critical for phone integrity. PRETTY COOL!!!

I wasn't really condoning the use of task killers. I disagree with them 99% of the time (there are some edge cases). I just gave the OP an option if he really, really wanted to for no reason whatsoever.

@OP: I would recommend leaving the pasture gate open.

There is an app called Greenify. Its available on Play store.
Just check it out.
It also helps to maintain the juice of the battery.. !!

To Free Ram
A more easy way to delete a minimum of 1gb of space which by doing so also frees up ram is to delete the dump state log cat. See every time your device has an error or force close issue, date is collected / written to the log file and this can take up ane enormous amount of space which when space is low also means your device user more ram. To do this go to your dial pad and type in *#9900#
This will automatically brings up options and then just choose to delete the dump state/log cat. Let it clear for a few minutes and that's it's. Try seeing how much space you have before and after and you'll realise this is a blessing.

[Q]ram problem

Hey guys, I have a problem with my RAM u see I only have about 140mb of RAM, which when I bought my phone they said that they was going to be 768mb of RAM. So the problem is that whenever I kill all app using advance task killer, there would only be maximum of 200mba of RAM.but now after flashing a ROM the maximum RAM is 140mb n after opening one or two apps my phone necessary really laggy as I would only have 60 MBA left.on top of that my internet takes up about 80 MBA. So I am angry about this. So is there anesthesia else to increase the ram?thx

Your phone is broken; You should sell it to me. I'm joking of course, I don't want your broken POS. Lol Im sorry, I mean nothing is wrong with your phone.
256 is dedicated to the gpu, then another 300 or so is dedicated to the OS, and Rosie UI. The rest of that is what you're seeing. Don't worry though, 140MB is plenty of memory. You need to uninstall your 3rd party task killer and just enjoy using the phone.

Tnx for the reply but my phone lags, bro how

If you are flashing roms, then I assume you are rooted. Get Titanium Backup and freeze Sense. That will free up RAM and speed up your phone. I am using ADW EX on the stock ROM and I froze Sense (found two parts of it in Titanium). My phone is faster than hell...
Matt

Even with sense running your phone shouldn't lag unless one of your apps isn't working properly. The way android background processes work, if an active application needs more ram than is currently free, the android system will automatically kill inactive app(s) to free up memory. The problem is with poorly written apps that maintain active status when they are no longer active or have unnecessary services that relaunch themselves when they are killed. Your task killer cannot fix poor coding. It only provides a placebo effect. At best it is unnecessary, at worst it will exacerbate the issue.

Guys I freeze sense but nothing happen I think it became even more laggy, how anything else to try

Have you considered flashin another rom, or reflashing the one you're using ? It might help.
It happened to me as well : phone was laggy and sloooow. I went into Recovery, wiped all data, applied the super wipe script (just to be sure) and flashed again my rom.
Been on it for two days, and phone is really fast and responsive.

Most rom devs seem to recommend giving your phone a day or 2 of normal usage to let the android os 'settle down'.

Well yes, you will lose all your data. As mentioned higher, you can use Titanium Backup to save them.
As for your messages, you can use a small app, like SMS Backup and Restore (free on the Market) to save everyting on your SD Card, and restore them after you're done.
Reagrding the max multitasking apps, I admit I don't know how many of them can be kept running. I usually have 2 or 3 of them going at the same time, rarely more.

He's saying that your free ram amount is pretty normal. I want to know where you're getting the free ram amount from? If its from task manager (included or third party) its probably wrong. Go to settings>applications>running services and look at the bottom. I found that to be the most consistant regardless of device. BTW, I currently have 215mb free with ~20+ apps running and I never kill anything. In comparison, task manager shows 97mb free with only 4 running apps.

that's because task manager shows only completely unused ram. Running processes in the settings menu shows unused ram as well as cached processes. Cached processes are automatically ended when ram is needed so the android system includes that ram in the available ram count. Task manager does not do this. It will only show the unused ram. If you take your total ram (from running services menu in settings) and subtract the total amount of ram used by cached processes the numbers in task manger will march the new total. Example:
Running services shows 332MB (this is my actual numbers by the way) with 162MB used by cached processes. Task manager shows 170MB free. The numbers add up.
332MB - 162MB = 170MB
*edit
To see your cached processes go to:
menu> settings> applications> running services> menu> show cached processes

[GUIDE] Ways To Speed Up Your Device

Are you tired of the fact that your device is lagging a lot when switching between screens or in gaming ??? Here is a little guide to speed up your device in most cases
1. Most common thing which is now popular with lovely pico owners is the new cute_price's oc kernel technique which could overclock your device without harming your nand, which we call as nand burn. cute_prince's thread: http://forum.xda-developers.com/showthread.php?t=2337886
In this case you can use these kernels- Jarvis kernel: http://forum.xda-developers.com/showthread.php?t=2325345
Pandora kernel: http://forum.xda-developers.com/showthread.php?t=2238754
2. you can use some task killers and an app called ram manager free & pro versions: https://play.google.com/store/apps/details?id=com.smartprojects.RAMOptimizationFree
this app helps to clear all the task running in background and freeing up maximum ram, you also get different profiles like more free memory, hard multitasking, hard gaming etc.
3. You can use an app called Greenify: https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
this app hibernates apps that are not in use to maximize free ram space and boosts up the speed of the device.
4. Reboot your device atleast once in 2 days so to load all the processes and apps to bring back the smoothness.
5. clear cache under recovery of the device
6. as mentioned above you can try some kernel that can overclock your device uptill 800mhz or higher (higher the speed, maximum chances of nand burn ) you don't need to create any special partitions for these kernels.
7. don't move data to sd-ext if you have a sd card partition, this decreases the speed for loading apps and lags your device.
8. Avoid live wallpapers because these acquire ram as well as cpu and drain battery with a faster speed.
9. Disable auto sync of data.
10. Disable unwanted apps to freeze the process completely
11. Uninstall unwanted apps so as to increase internal storage and increase performance (menu loading time and os loading time)
12. Decrease use of widgets because these use hell lot of ram and cpu usage.
To determine which process is running the most in background, better use better battery stats app from the play store: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
13. Hit Thanx the most important thing that would speed up your device
Reply some other techniques that you use and i am gonna add them too, these were my own ways to boost up
I don't use scripts because they don't help a lot (no offence )

if you want 2GB Additional Ram than Skip this Step.if not then edit this value as your wish.
Than tap "Create"
Than this application will start create Additional RAM For Your Device.
This Creation Speed Depends On Virtual RAM value,Your Storage's Read-Write Speed, CPU Calculation Speed.
So wait untill Complete this task!
When This task Has been completed, Tap "RAM On" Button
And after than,Cheak mark Autostart button to on.
Its all Oparation of "RAM" App.
