It's my understanding that this phone comes with 1gb of ram... Why is it that at any given time only about 350mb of that is free to use, and only 768mb is available total? I realize the OS needs ram to run, but I can't imagine that it needs ~600mb.

bump.
I want to know as well, the lowest I get it is 326mb with easy task killer,
I assume 768mb available is just what they give us, it's always less than advertised.. but I dont understand how on my last phone there would be 100mb free but itd be running like.. ****

I believe a certain portion of your RAM is reserved for system devices like Radio and isn't seen by the Android OS.

I noticed this to, but if you ever had an older Gingerbread device, even running CM7 they came with 256-384mb of Ram. By the time the phone was booted and all the front end services and apps were loaded, you had roughly 90mb of free ram to play with. I heard ICS and JB would at least double that, which is in par for the 768 +/- Ram usable. With a custom ROM, and removed bloat, I have close to 500mb free at boot time, so still a lot of front end apps are being loaded and using that Ram.
I think this is why a lot of older devices, even with 512 ram had a hard time getting an ICS update. Processor wasn't really the hardware in question, but moreso the Ram.
I hope this makes a little sense since I'm still half a sleep
Remember that android loves to fill up your ram with your apps for quicker launching. Android actually runs worse when you have free ram. Go into developer options and limit background processes to 0 and see for yourself lol

but look at my attachment, my ram is only 275mb.. where are the other memory?
why is it like that?
Apparently I have 342mb. Maybe it doesn't all show up there?
Maybe some is reserved for android... the rest for applications, I don't know.
I think reading Von Neumann would do a lot of good about this.
yeah mine says 350MB
And what would the gpu do without any memory yes it shares that 512mb ram with gpu.
Hmm...This is interesting. I wonder where the rest is
lol I gave you the answer above The GPU has the rest of the ram.

No it dosent, we don't have dedicated graphics. Our GPU does not need dedicated Vram. The rest is reserved for android. The GPU can access the memory, but it's not reserved just for the GPU.

Is that true? Android is the one who is getting the other RAM? But that's so huge. Almost half of it.. Everytime I look at my running apps, it never went to 300+mb (combining used and free) that's why I always have a laggy apps and games (2.3.4) because of the few ram's left.. I thought if you have few ram left on your android, phone is running great, because Linux handles it different from Windows. But that's never happening in my case..

Thats right, with android the less free ram the better, the lag will be down to the CPU being overworked, try overclocking

Hey. So I am by no means an android noob but after installing a clean rom (bugless beast 10/31 build) I have anywhere from 100-150ish free ram right off the bat and ive seen other gnex users with over 300mb free with maps and other apps in the background. I know free ram is wasted ram but something seems wrong, is this normal?
P.s When I look at running apps/cached apps all the numbers register 0.00B. Maybe bugless beast is kinda buggy?
P.p.s I'm using fugumod kernel but its like bare bones stock so I don't see how that would affect anything
It seems like it. Try flashing another Rom so as to make sure it is not a phone problem. Try cm10.1 or stock. Hope it helps.

I'm on XENON HD Stable-4.0 Franco kernel r364. Once I start using the phone, I have about 40 mb free more or less consistently. The performance remains excellent.
I also use the "seeder" app, which definitely helps my performance. The community is divided as to its effectiveness and I'm not sure why it helps in my case.
Not to be insulting, but why do you care about free memory? Is performance poor? Are you comparing it to other operating systems that have a different memory management model? Just curious where you're coming from.
Who can have the most anemic RAM reading?
Any ROM counts! Post a screen shot and good luck.

Guys I don't think you guys should be worrying about ram usage. Unless your phone is noticeably slow because of low ram usage, you won't gain any benefits from lowering your ram usage.

Unless the process that is taking up the ram is actively running in the background, then yes.
Otherwise, inactive ram takes up the same amount of power as active ram.
Clearing your memory isn't a very good idea. Unless the program that clears your memory is specific on what type of process it ends, the system would just have to load up that process you just ended which also results in higher CPU usage, and a slower system.
If you are worried about your battery life, check to see what process is actively running in your background and end any that you don't need as these are just taking up your CPU time.
Correct me if I'm wrong haha.

You aren't. Watch what you ram does after you clear it out, it builds back up which is causing the CPUs to work, when before (if they were inactive) would just sit their doing no harm. It causes the CPUs to work to bring things back to light instead of just recovering what was covered (so to say) there about 100 threads on this for each phone and even more through out the world of RAM management.

Why do you worry about it? Unused RAM in Android is wasted RAM. Let OS manage it, you don't need to pay attention.

+1 Android intentionally keeps commonly used code and apps in memory to save battery. Keeping apps in memory is more processor efficient than repeatedly dumping and loading them which increases load on the processor, and processor usage makes the difference in battery performance, not how much memory is being used.

Excellent post. I usually get to respond to these so thanks for beating me to the punch with very good information.
I know Android does a good job managing RAM and that other task managers are worth using.
I did think that using most of the RAM would slow down the tablet.
Thanks to all of you for explaining it to me, I really appreciate it! Now I'm more confident about having only 2GB of RAM.

Also, there are some apps which are using RAM that I don't use, haven't used, and haven't opened. I was wondering how to get them to stop using RAM because there's no point for them to use my RAM when I don't use the app.
Most are stock Samsung apps.

I'm just curious, does anyone else have unusually high RAM usage? I'm rooted and on SkyDragon, using SkyDragon kernel. My RAM is always between 1.9Gb and 2.3Gb. I have no idea why though because when I look through the running apps, there's not much there, not enough to make it that high anyway.

I'm rooted with SkyDragon kernel and upon a reboot, RAM is 1.5GB free, but as the day wears on, it drops to between 400-600MB free, usually around 500MB free and closes other apps as needed to maintain that 500MB free.
It was the same before I rooted or flashed the new kernel, just seems the way that Android is running the RAM on its phones nowadays.
