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?

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.

a phone OS using more ram than Vista??? not a good sign. God where are the AOSP roms already :crying:
Kernel knows it has more memory available so apps are more likely to stay in their suspended state, rather than removed from memory.
But I enjoy the 2GB of ram for sure.

Using RAM is not bad; needing RAM is bad. Android 4.0 can easily run with less than 400 MB, but some things can be a little faster when they don't have to constantly reload.

This. Everything switches back instantly!!
One of the most frustrating parts of the HTC OneX for me was when i was reading a long page of comments on sites like the verge or typing up a forum post. If i left the browser to reply to a text or facebook notification, and then returned to the browser it would always reload a page, and at the top.
Even the (heavy) Sense 4 launcher would have to load up every now and then.

i wasn't making fun of android, i was making fun of touchwiz. too much bloat.
If the RAM will mean Nova Launcher wont reload itself as much as it currently does on my Incredible, then that's reason enough for me.
Having had the 1X for a month the 2 gb ram was one of the reasons I switched.
The 2GB of ram (and LTE) has been excessively downplayed by the International crowd because..well..they don't have it. The fact is the 2GB of ram should allow a stock phone to reload things much less. If you want to look forward 6 months to a year, I think the difference will be potentially much larger when we start to see creative devs tweaking their kernels to really use this extra ram. This is a ground breaking hardware move. We haven't even really begun to see what is possible. Judging any of these based on stock software at release is pointless. Think about how much better other phones have gotten after a few OTA updates....this device, especially with the extra ram is really well equipped for a long time.

By the time any phone will actually use 2gb of ram, im sure most of us will have moved on to a new phone already. Of course having the extra ram is good for bragging rights, but does it actually mean anything? I'll say no, but im sure some will argue that.

This is good in theory but everyone on here is talking like we have been missing two gigs all this time in our phones. If you are coming to the S3 from a single core phone of course this is night and day. My SGSII has NEVER.....I repeat NEVER run out of memory lost track multitasking or had to close out multiple apps to make room for more.....how many apps does one need sitting in a suspended state?.....I have 5 or 6 apps open at any given time with PLENTY of room for more...sure the extra ram is nice to have, but its completely unnecessary ....dual cores with a gig of ram have NO problem doing heavy multitasking .....ask anyone running as SGSII or Gnex.
The extra ram in the S3 is there to offset the loss of quadcore....its a nice helping hand to the Krait chip but not necessary for everyday multitasking that the average person does.....I don't know what phones alot of you guys are coming from but from the sounds of these posts they were serious under achievers.

i think the reason you never saw your device running out of room is likely because the system knew how much memory it had to work with and was always adjusting things to accommodate as much memory....if the system had more memory available to it it can behave differently....it's not about "how many apps one needs in a suspended state", it's about "the more apps you can keep in a suspended state the quicker the apps will run for the user"
i know this isn't x86 and it's not windows, but the analogy still stands, consider Windows 7
if you build a pc using it with 2Gb of ram it will run just fine, it will use somewhere around 1Gb of ram sitting idle, using it for the prefetch cache to be ready to launch your most used apps while maintaining a safe amount of memory for sudden useage/overhead
if you upgrade that same pc to 4Gb of ram, it will use close to 2Gb at idle.....it's not quite linear as that but you can see a direct correlation between available memory and memory utilization
the Linux kernel behind android appears to work very similarly, it will keep the most called upon code in local memory so that it launches faster when next called upon. the more memory available to the kernel, the less time it can spend killing apps in order to maintain that same level of free memory for the unexpected execution of a new app
the more memory it has, if it is written/compiled to take advantage of it, the more potential for performance is there.
I would say the 2Gb of memory is more easily utilized than the additional redundant cores in the Exynos kit. I have been looking for some real data on Android and SMP but I know recently Intel made a rare public statement about how it is not ready for even dual core utilization. I don't think Intel would make such a specific claim without data. I don't think the Exynos users are really getting much good at all from the four cores other than synthetic benchmark scores and I think they could see more benefits down the road from more memory than redundant A9 older technology additional cores.
disclaimer: I am still learning about all this so if some smart guy comes along and sees something above that is not quite right....it's not because I am making this up....it's what I understand to be true based on reading.

You are pretty spot on for the most part....but the difference here lies in the amount of ram needed to cache applications and perform extended tasks.....the reason my GSII never runs out of memory is because it has plenty for any array of tasks. While caching 8 applications I use all day...and still have anywhere from 325 to 400 megs available for any other array tasks .....I just can't see where I would need more.
As for your earlier mention of custom roms.....this becomes even less necessary ....right now a stock GS3 is using over a gig.....that's because its loaded chock full O'carrier BS on top of all samsungs layers of bloat and BS "features"....you strip all that crap out and you have a 275mb OS and more ram than you will know what to do with.
Bloat is the only thing requiring this extra ram because its running at system level which is also why Sense stuffed a dagger in the H1X.
Performance for launching is helped greatly by the processor for anything not in ram and the threshold for my phone is 64mb....which means my phone will not start killing of apps until that's met.....I could not seem to hit it just messing around.

right on, yeah i agree it's overkill right now. I just think within the next two years, we will easily see multiple areas where having more is better than having less. I am thinking way outside the box but I am seeing visions of custom kernels that are doing some extreme caching, even running a VM type environment.....actually I am thinking of running Android and perhaps there will be an opportunity to run Windows RT or some desktop version of Linux simultaneously......something a device with even four cores and 1GB of ram would have a hard time doing.....and that's not to say it would run well on the S4 US version either, but it is certainly more suited for it

You are partially right. My sensation xl and my friends galaxy note works multitask pretty well with just 768mb and 1GB ram. But that was on Gingerbread. Once we upgraded to ICS multitasking suffers tremendously. He even blamed me for persuading him to do the update. For GB 1GB is enough. For ICS 1GB is not enough if you want the best multitasking experience.

Hello there.
As someone coming from a very laggy-slow-multitasker Galaxy S3, I am really looking forward to the possibilities the 3Gb of RAM of the GN III can bring to me in my every day lfe.
I mean, I would love being able to switch to multiple apps fastly without having to reload them each time because the system had to kill them due to low memory (nice work, OOM ^^).
And this upgraded multi-windows feature with mutliple apps instances is really looking awesome.
So, here's the thing.
According to that thread on GN II average available free ram : http://forum.xda-developers.com/showthread.php?t=1923380 people can enjoy up to 800-1Gb of free RAM which is great but at that time I could not and would not afford to purchase this device, the SGS III being quite new.
And as of today, I read a thread confirming the Samsung Exynos 5420 in the SM-N900 version.
But what almost killed me, so to speak, is the available free RAM on this screenshot (see attachment) : 14% out of 2700Mb, which is less than 400Mb. THE HELL ?? What am I supposed to do whith that few ...?
So what do you guys think ?
Free RAM is a waste ram, enough said. Only my note 2, the free ram stays at 200mb free on average, never ever faced any lag.

As I should have expected, I'm being answered with the "free RAM waste" speech.
Let me tell you that this is completely true. BUT the problem here is the free RAM you have at YOUR disposal on boot.
How much will Samsung leave you to play with ?
If the system and the home launcher utilize all the memory so that you have only 400Mb left (as in this screenshot) what can you do with that less ??????
I get about 250Mb left on boot with my SGS III and it is NOT ENOUGH to do some multitasking.
So I will not leave free RAM, I will use it to my heart's content to do MULTI-TASKING with the apps I want to USE and switch between AT WILL without having to RELAUNCHING them. That's all
Therefore if I have only 400Mb left, then this device won't satisfy me. I'll be better on a Nexus 4 I saw with CM and over 1.30Gb free RAM to play with ! ^^
THis 400mb ram left is not on boot man, it could be after several apps opened so when you open a new app, the task manager adjust itself by clearing old apps from memory to find space for new.

Here's my N2 which I've never had a multitasking issue with. In fact, the number of apps it can keep alive in the background has always impressed me.
With 116 installed apps and dozens of Samsung's apps doing whatever it is they do I have 200MB of "free" RAM.
When I kill all active processes I have 850MB free.
Mali in the N2 reserves 250MB of RAM for itself. Adreno 320 reserves 500MB of RAM for itself in devices using it. Adreno 330 in the N3 will reserve at least that much, maybe more. I'm guessing that between Adreno's needs and the RAM some of their new apps (two concurrent instances of the same app, enhanced multitasking, updated S Note with Action Memo) need Samsung wisely included 3GB of RAM on the N3 to prevent the very scenario you're afraid of.
You do realize that open apps are counted in the "used RAM" the picture you posted shows? So that device that was being tested could have had a dozen apps open in the background for all we know. And a dozen apps open with free RAM still available would be good, not bad as you're indicating.
P.S. - The part you're missing about the "free RAM" speech is that the idea of having free RAM is kind of stupid. If an app can perform better with more RAM and the OS sees RAM available it'll allocate additional RAM to that app. If more apps join the party the first apps RAM will be reduced to provide a proportionate amount of RAM to other apps running. In other words there's absolutely no reason to have free RAM on an Android device; at least when apps are running.
Actually it's well explained that why we should not worry about ram anymore. good read.

True enough.
If this device was running many apps in background while performing this CPU-Z scan (on the screenshot), then, I would not be worried at all. So I really hope that was the case.
What matters the most to me, is how much ram is allocated to the user, so that when I install my apps I can launch them and switch between them to my leisure without having to relaunch them.
Therefore I do expect to see very low available RAM, but only because of my doing : launching many apps, the apps I use every day. That's my all point.

Very interesting. Now I know where the GPU takes the RAM it needs.
And the part where an app is being less allocated in RAM is strange. I never really saw an app releasing RAM without being killed.
But anyway, with my current 1Gb SGS III, I cannot to do a lot of multitasking and I would really love to have at least 1-to 1.5Gb of free RAM on my GN III that I recently pre-ordered.

1GB on the Exynos SGS3 was probably too little. As Samsung adds sensors and features that are persistent they reserve RAM for themselves and don't release it when other apps need it. So with Mali taking up 250MB the Exynos SGS3 had 750MB of RAM that was usable not counting what Samsung's apps permanently reserved for themselves. The S4 SGS3 had 2GB of RAM because Adreno used more RAM than Mali. It ended up performing better at multitasking because there was only 130MB of that extra RAM dedicated to Adreno so there was lots more available for apps. HTC used 1MB of RAM in the S4 based One XL and it was a multitasking disaster because Adreno ate up 330MB of it and Sense itself is no featherweight.

That's very detailed and interesting! I had no knowledge of this while looking for ways to enhance my SGS III multitasking experience. Now everything seems much clearer. Thanks!

Ah ! Finally some good news! Is this free RAM upon boot and/or when clearing memory?
If so, then it would be expected that there won't be close to 2Gb of free RAM, since I expect that TW home launcher will use a lot of RAM with all new features such as AirCommand. Don't you think?
Anyway thanks for that screenshot!
If you're really insistent on having 'free' memory, you can change it with a tool like this, needs root
if however, you read (and understood) the article posted above by rl421403(good read, thanks for the link) you will realise that the Engineers who designed the system do actually know what they are doing.

Well, no point having 3GB RAM if we are not going to use it..
However I think we have more than enough RAM to work with. 'Free' memory is more than GN2 if you check.
Here's another good article from Dianne Hackborn, a s/w engineer at Google that explains multitasking in detail. A lot of issues people have with certain apps when it comes to multitasking aren't due to Android or RAM but the way the apps themselves have been written (EG: sloppy).

Well, I tried something similar that used the MinFree values : zepplerinox supercharger script and eventually it was more than hassle though I had more multi-tasking capabilities.
But on many occasion my device froze because there was no memory left so I abandonned until I would find a better device.

I was worry sick about the 3Gb RAM, because a last minute serious rumour (few days before the IFA) stated RAM would be 2.5Gb and not 3Gb with a Antutu benchmark as a proof.
Then we learnt the real truth.
Anyway, it would definitely seem to be more free RAM than on the GN2, much not as much as one would expect when packing an extra 1Gb RAM, meaning Adreno 330 uses much more as long as TW home launcher.
By the way, is it me or your Twitter link does not work ?

Now that I think about, when you said the GPU uses the system memory, does it use it on the go or does it have it's dedicated allocation no matter what ?
Because if I am correct, on the previous page, the screenshot shows 2.75 of available memory out of 3Gb. I gather the 250Mb is dedicated to the ROM, right ? So what about the GPU ?

Not for me. Even though I flash CM on it. A few services (twitter, music etc...), a few widget and you're fu**ed...
Meaning, upon boot, I have 200-300Mb of free RAM.

2,38Gb?
Where are the 3Gb?
One screen shows 2,7Gb. That's ok. I suppose that rest of ram is for graphical purpose.
But in this screen I only see 2,38Gb? Where are the other 620 Mb? How much memory is graphical dedicated? 300mb or 600mb?
You can consider the new Adreno 330 from Qualcomm to use at least the same amount than it's previous version - Adreno 320- which is 550Mb as explained in page 1
sorry offtopic... but I heard that samsung will offer minimum 32 gb storage on galaxy note3 but according to op screenshot this is a 16gb N9000... so are they still offering 16gb versions for note3?
The amount of RAM in use at boot doesn't surprise me at all. Where do you think all those nifty new resource intensive features live? Even with that and Adreno's piggish appetite the N3 still has more free RAM when cleared than the N2 does. My N2 with memory cleared in on the left. @NZtechfreak said his N3 had no material apps on it and mine’s loaded so that may make a difference. Regardless, I don’t see RAM being an issue based on what’s been posted so far.

Exactly. And you can't expect there not to be errors with so many variants of screen sizes and OS updates.

Hello! I am thinking about changing my poor old Oneplus One for this beast. But I am worried about the RAM quantity. At this moment I have 3GB RAM and I don't know if 4 will be enough.
Isn't TouchWiz 4GB = 3GB AOSP debloated?

Of course it is enough + you won't keep your phone for more than 2-3 years. TouchWiz got better, but not perfect. My phone still has ~1.5 GB of Ram left. My notebook has 4 GB Ram with fast SSD, don't see any slowdowns on Win 10 Pro.
With the poor ram management 2.5 GB is enough because at no point it uses more than that on our phones. I have apps refreshing when I come back but only half of ram is being used.
in my opinion, 4gb is not enough..... For that kind of high-end phone, samsung should have put 6Go at least into it. I'm talking about ram managment which is pretty bad in android and when you take a look at speedtests (even if this is not reflecting real daily uses) you can see than phone with 6go of ram are able to keep many apps in memory way better than the s8. When you start to run heavy apps or games, the built-in memory killer kills a lots of background app and then when you need to switch back into an other recent app, the phone almost reload it :'( That's frustrating
4GB Ram is enough. More RAM means more apps running in background which means more battery consumption. So 4GB looks a good balance here atleast for S8 which has only 3000 mah battery.
i don't think so excuse me. Of course, more ram maybe means more battery consumption but i prefer that and kill apps runing in background manually to keep battery life rather than the os kills things that i still need :/
When you have 4gb then 4gb isnt enough, when you have 6gb then 6gb isn't enough... its never enough.
4GB is enough for most any smartphone. I also have a OnePlus 3 with 6GB ram and while it can keep more programs running in the background, it never totally accesses the entire 6GB ram. Read this XDA article on RAM: https://www.xda-developers.com/the-ram-conundrum-do-we-really-need-6gb-ram-on-android/
4 is enough, and please after buying it do not ask about why just a little of it is free! The ram is for holding services and apps in background so cpu should not work again to bring them up, if it's filled do not be sad, it's natural.

Why should you want to keep many apps in memory? The S8 loads them so quick anyway.
Who needs in real day use to keep in memory 5-6 games plus 6-7 apps ? That's what they are doing in speed test , but in every day use it's not need for 6-8 GB ram in this moment. In my opinion for the manufacturer it's simpler to put more ram in a phone instead a better over all optimization.
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
