why does the vibrant not recognize all the ram even on 2.2

Guys, how can I get my samsung vibrant to recognize all the 512mb of ram. I thought froyo has all the software and kernels and stuff to recognize the full 512mb of my phone not just 308mb. Do I need to flash a new kernel or something. I have the nero v3 rom on my phone, with voodoo enabled. So how do we fix this?

308 MB you phone is showing you is the correct amount, your phone does have 512 MB of RAM total. However, part of that is used by the phone and android system to supply your phone's graphics card and other functions such as a RAM disk if I remembered correctly. In addition, You don't want your phone to run out of memory because you are running a game and missed that all important call right? well part of the RAM is reserved to keep the "phone" portion of the Android working.
It is a common misconception that Froyo will "unlock" this hidden RAM, but in reality we are already using all the RAM that came with the phone. The reason some HTC phone shows 512 MB of RAM is either because the phone is reading the "TotaL" amount of RAM or in the case of G2 the phone actually came with more than 512 MB of ram but advertised as 512 MB (the extra RAM is used in the same way as the Vibrant, GPU/Ram disk/Android, etc).

What about the iphone, my cousin always gets 300t mb of free memory on his iphone 4. Android can't be that much of a ram hog. By the way doesn't the power vr gpu have dedicated ram for it self, I man come on, its a high end phone. Samsung is really messing up on there phones.

My question is *why* do you need more free RAM? Are you really running out, ever? Don't think of it like a PC where you need free RAM as overhead when apps start utilizing more and more. Android will free up more RAM as necessary by killing apps that are preloaded in the background. I've never run into a situation where I've run out of memory, couldn't even tell you what happens when you do. I don't use task-killers, run a ton of widgets, and I've never seen it dip below 60-70mb free.

Yes I do run out of ram. Every time I watch a flash video and while leaving no heavy ram using apps to be multitasked, after I finish my vigo and go back to my other apps I finder them killed. It gets on my nerves. I expected more out of 512mb. I also spent too much money for my phone for it to perform under shar what it's specified.

So much for multitasking, right?
Phone has 384 app accessible ram. Typically runs with ~100ish free after a fresh boot with a stock ROM. The browser can take ~30mb, so that doesn't leave much to multitasking with. When ur phone starts auto killing performance decreases. They should have h put the aeverised ram in the phone, instead of playing the semantics game. Even Verizon updated their fascinate specs to change that to 384.
I'll make sure to check this before I buy my next phone in a couple weeks tho (soooo excited!!!).

This means that this is a software issue, not hardware because the tab has the same processor found in the vibrant. 400t is allot better than just 300, not only but the tab also requires more resources with it's 720p screen.

It's not a software issue.
And yes, 100MB RAM in a smartphone is a lot.
It's like getting a computer with 4GB RAM and ripping a 2GB RAM stick out out of it.
There's 128 MB RAM that isn't accessible to the system The OS itself probably uses abut 100+ MB RAM, and once you start installing applications/services that start eating up resources.
Some say the 128 is dedicated graphics ram (fast graphics RAM to allow the Hummingbird to achieve it's faster GPU performance). What a waste. I'll make sure my next phone isn't built like a game console.
They should have at least added another 64MB RAM the way HTC did in the HD2/HD7.
The phone has as much App RAM as a mid-range Android device (think HTC Aria). It's factorable, especially if you want to multitask. Running multiple applications on this phone, I basically have to manage my apps they way I did on Windows Mobile (i.e. open task manager to FC the browser, etc.) because you don't want to be playing a game or doing anything somewhat important when the phone starts trying to auto-close background tasks to recover RAM (and some services will simply restart themselves immediately).
Good phone, bad execution in the software, and they should not have advertised it as having 512 RAM, because to anyone that isn't an idiot Graphics RAM is not synonymous with Application RAM, and 128 less RAM is quite a big chunk to be missing.

Virtually every computer on the shelf at Wally-World and Best Buy do exactly this - the motherboard graphics chip uses system RAM to operate. Admittedly does not directly correlate to a phone, and they should make a disclosure, but there is ample precedent in the general marketplace.

I don't understand why some of you attribute a free RAM amount (or lack thereof) as a memory hog?
If RAM is used instead of slower disk I/O it translates to a better user experience, the OS is good on keeping the taps on the memory and clean the thrash by itself, but nothing can prevent poor coding and a single rouge app can become the memory hog independent of how much RAM your system has, it might eat all of it.

The real problem is that the phone has only about 150mb of free ram and that'd on boot up. If the phone does have some ram dedicated to the gpu from the system ram (known as shared ram) then why
Don't other android devices do that too, and the iphone has more free ram on boot up then what is user acsesable to me. I thought the gloriose sgx540 had it's own high end dedicated ram for graphics?

If you hate your vibrant so much why do you spend so much time on the forums? Dont seem to contribute much so just go get a new phone and leave us alone.

And how is that a problem?
Do you have an immediate need for something that requires 150+ MB after the boot?
Here's an absolutely healthy linux system with 2GB of RAM:
Code:
free
total used free shared buffers cached
Mem: 2049868 1982076 67792 0 146988 840748
-/+ buffers/cache: 994340 1055528
Swap: 6008824 820 6008004
I will be worried if my swap is being used a lot, but using my memory on the system is good.

I agree with this. 512 advertised, 308 seen, 150 Available after a boot....my phone keeps running out of memory so often its sad. It can never run my music player and my gps software at the same time. When I switch between the 2 apps, it closes the other one and its really really sad to see. ****ty job samsung, ****ty job. I hope the galaxy s mod gets ported for the ram which opens 338mb. At least its something.

I just went on a 700+ mile car trip with the music player and gps navigation software running the entire time. No problem. Was even able to simultaneously play games while my wife was driving.

you have a rouge app/apps running that memory hog your phone, getting 30MB of more available RAM will not save it. You need to find what is hogging your phone, I am yet to see a message that my phone is low on memory, sometimes I do a lot of browsing, txt, mytracks and playing music with Pandora or stock player at the same time and it never complained that it was low on memory to run these.

Who said that I hate my phone.I'm only truong to find out shar mashes it not recognize all it's ram. In this era, ram is a huge factor to run apps and most importantly newer os updates like ginger bread and honey comb. Don't wanna run out of ram right when you boot up your phone don't you? And if the tab can recognize more ram than this then this means it does gave something to do with software. I guess we have to wait for samsung to release froyo, because im sure that they will gave all threw tweaks that will boost this phone very high, bedside from shar I've noticed, all the,roms out thete dont really boost this phone allot. How do I know,i gave nero v3 and that only boosted me to 1137 on quadrant from 2.1 and with voodo enabled I get 1500 max on quadrant. Oclf the same thing too. so all I'm saying is that it's definitely a software issue. Pretty sure android does not hog 400mbt. And no sgx has its own ram for sure.

I still don't get how you're running out of RAM. Right now I've got Winamp streaming through BT and have started streaming a Flash video. Also running are XDA and Maps. No hiccups.

Using full ram with root

I've read that 1 of the 2gb of RAM is used for the touchwiz so you effectively only have 1gb. If you install a custom rom, ie. cyanogenmod, do you get to use the full 2gb then?

Pretty sure its ICS that takes up the space and its not a full GB. I don't have the phone but a friend has around 1.6 - 1.7 Gigs free at max.

I don't think that would work out, considering the international GS3 has 1GB of RAM and runs TouchWiz.

So much confusion, let's spell this out. First of all our phones have 2gb ram, period. The GPU requires about 0.38gb of the system's 2gb because it doesn't have its own onboard memory. So no matter what software you run, you'll be starting out around 1.62 available.
Different operating systems, frameworks, skins, and applications will have different memory footprints. Touchwiz is probably a bit heavier than AOSP (CM/AOKP), so after a clean boot you'll probably have more free ram running an AOSP variant.
Honestly its all kind of moot at this point however, because I doubt in either situation most people get anywhere near using the all remaining RAM with current ROM offerings. Key lime pie may be another story.

Yeah to his point about not using the RAM is just stupid, unused ram is wasted ram meaning you have it for nothing, for example on stock cm9 you got 1.2 gb free most of the time, 500-600mb free, touchwiz manage ram better but still leaves a lot behind, look up what ram does and you will understand why unused ram is useless

Isn't it ideal to have unused RAM so that when you open apps and multitask, you the memory to keep them alive? Maybe I'm misinterpreting, but if we never had unused Ram then we would never be able to multitask, right?

To a certain extent, I for one think there's no reason to try and utilize all of it for nothing. And it's pointless to complain about having extra

This is quote from something I read in pc mag
" This has to do with extremes. Remember that every so many cycles (don't remember on current ram), your memory has to completely refresh its contents. If you have an extra 16GB that you never use, then you waste time refreshing all of that ram. Also on this note, higher densities, and larger quantities are harder on your controller. For maximum speed and stability, use ram appropriate for your usage pattern"

While that is true, ram come in discrete chunks and 2 gb is noticeably better than 1. At a certain threshold the memory manager kills off old apps to free up ram. More ram means more recently used apps remain loaded and available sooner plus i have no issues with many pages open in a browser. I typically run with around 600 mb free. Only my dell streak i would often be under 100 and unless i manually closed apps it really bogged down.

1gb of ram is not for TW and the rest for apps....its 2gb total...in reality like 15mb total

RAM usage

Hi guys,
I am curious about your experience with RAM usage on your S6E+
If I'm not doing anything (just checking RAM usage with my SmartManager) it says: 60%
- 2.2GB System & Apps are using
To me it seems alot, since it leaves me "only" with 1,4GB of RAM left.
So I would like to see your experience and I could judge better.
best,
Dpool

I just dont understand why people complain about "Ram" usage on an Android, free Ram doesn't mean "fast" mobile.

No, Free RAM does not mean that. But it means that I only have little Free RAM left, without doing anything. I'm worried about multitasking, since it supports split screen:
- 1 half of screen I'd play a game
- 1 half of screen I'd watch a YouTube video / Stream about the game
Well not all Android games support split screen, but just an example of where I can see heavy RAM needs.
Also, I did not complain, I am just wondering if it is normal to have 60% of RAM occupied by System itself. So, DemonSoul, may you share yours to compare?
Best,
Dpool

Mate,
Samsung system apps and other Google services are using a good amount of RAM. You could use App disable pro and disable some of the unwanted system apps to free up some more RAM. Samsung does have a feature to kill a process in every 10 mintues. So that app you don't want running in background you can use that feature.

Killing apps will decrease your battery life and hurt performance because Android will just load them back up. It costs cycles to constantly load & kill apps. Apps don't burden the processor when resident in memory, hence don't expend battery or reduce performance.
Keeping memory free on a Windows PC was important decades ago when we had <1GB, and when memory got full, programs were shuffled off to the swap file on the hard disk. None of this applies to Android. No phone with >2GB of RAM has memory problems under normal circumstances.

how much free ram do you have on your phone ?

hey I am considering buying s8 plus
and I would like to know about the ram the free ram after you clean the ram from device assisstant ?

Is this question really the deciding factor in purchasing this phone? Will you not buy it if it has 100mb less free memory than you'd want?

well I just want to study everything
the only thing that keeps me off the s8 plus is the ram as it is very important for future updates and phone's performance over all
if it is for example less tahn 1 gb after freeing ram with almost no junk apps in the background then I won't be getting it however some tests on youtube showed that it is a good multitasker so I guess I am fine now
but it won't harm if you posted that screenshot XD
I had note5 but the screen is broke so I am deciding for the next two years a very tough decision xD no going back

After cleaning :
Available RAM : 1.8GB
System and Apps : 1.6GB
Reserverd : 636MB
Of course, remaining RAM depends of the number of programs installed nd running in background, even if you try to kill them from the assistant. Don't know if these information are relevant or not

I had 1.3g of memory available after clearing everything, but i have 200 apps in my app drawer, maybe a fully wiped phone would show better results.

I have 1 ram

expanding RAM usage on 12GB model.

Developer options allow one to limit the number of background apps that use RAM. But they allow 0-4 apps or the "standard" option.
For those of us who have the 12GB RAM version, is there a way to keep more apps in memory?
I keep having 5.6 GB RAM available and I want to use it...

This is a good question. I notice the same thing on my 12gb model

i was tempted by the 12gb, but having to wait two days for it to ship kept me in the 512gb model personally, never been a patient one, never will be, 8gb is already overkill for a phone anyway, heck 12gb is 4gb short of what an actual gaming PC (the kind that play actual games not bloatware) should be minimum specced to, you're not gonna need that much power on a phone and if you do you're using it for the wrong things.
i wouldn't have minded a 1tb 8gb model though, i had to severely cut down my music library for the moto z force when i originally got that.

Well I just saw 4.4 GB RAM left only. I do wonder if there is a hard limiter after which preloaded apps are killed.
Regarding the debate of an overkill, I'm old enough to remember a time when the Intel 586 CPUs were promised to have "infinite calculating capacity"
The only reason I bought this model is that the s7 model I had lasted enough (2.5 years) to become too slow.
I'm hoping this device will last longer.
In any case does anyone know what the "standard limit" of allowed process is on this model and how I can force all RAM to be made available?

stop asking shovelware developers to script-kiddie in 64 bit, there's no kind way to say it.

That option is to limit apps, not allow more.
Phone uses LMK values probably coded in kernel and its not related to option you are seeing in dev options.
Also, 6gb ram used is alot, what more do you want to keep in memory, are your apps reloading or what?

I like my browser to have many pages preloaded (640 MB) , several texting apps, email, forums, videochatting, etc. XDA app takes 248 MB. Right now apps and system are using 7.2 GB of RAM...
This really is a mobile computer for personal use and that's why I bought it. I like to have all apps and pages preloaded and use them as a reminder of what I need to stay in touch with.
Right now everything loads fine, but in the future apps will become heavier and I'm hoping that Samsung isn't limiting that.

U can't know and also you can't control it anyways, we can just hope Samsung didn't set memory killer too aggressive.
Also you should turn off auto memory optimisation in device care menu as it kills apps daily.

I did the above and can report that I'm at 3.3 GB of free ram. I haven't restarted in 4 days or killed any apps.
So it's not an issue, Samsung does allow the system to use the available RAM.

You're not supposed to be touching that option and no, your device isn't killing your apps after 4 of them are running, you can keep as many as you want in background until you run out of memory.
