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.

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.

I have 7 screens in the main menu full of games now on my Xperia Play. And have 149MB free space. Use the SD card for apps, thats why it came with a 16GB card. If you need to move your apps to make space go to "settings" then "applications" then "manage applications" then on the top "On SD card". Any that are not ticked can be moved to SD card to make room.

Hmm, when you say "loading a lot of apps and games" do you mean running two games at once?
Downloading doesn't have to do with Ram availability. You can download everything as long as you have free space in your memory card .... But running them all is not a good idea even if you have 1gb free ram

this isn't windows mobile you guys... windows mobile stored applications in ram, and most winmo devices need a hud battery (hold-up battery) to maintain that application store when the main battery died. ANYWAY...
ram does not equal app storeage on android. Your apps can be downloaded to nand or sd card...
the xperia play has like 1GB nand/flash for the OS and data partition, plus apps2sd gives you virtually limitless app storeage. That is in the addition to the 400mb of RAM. Remember RAM and NAND/FLASH are 2 completely separate things. Volitile and non-volitile. RAM needs constant flow of power to retain information, NAND does not.
the 400mb of ram is useable at all times regardless of the quanity of applications installed, it's only effected by current running apps, and even with only 100-200mb free ram... that's plenty of any program you want to run, the memory management in android will assure that the active running app will have adaquate resources to run the app you are wanting to run, it silently closes inactive apps in the background to make most efficent use of that 400mb

I wasn't meaning it to be insulting and it's hard to tell where people are at on the technical level, but as a first time android person, and in sometimes first time smartphone person things can be a little confusing.
I just wanted to make sure the foundation was good in case there was any confusion.
Like I said I didn't mean it to be insulting, I'm honestly trying to help.
is'nt it really 512mb ram? but i think the system holds off a certain amount to run the OS or something so we're kinda left with 400mb. that said i think the real thing here is WE are'nt left with anything as WE dont do anything with the 400mb, the OS uses as it pleases depending on how many apps are running, surely? but i think johnsongrantr put it well....

yea I have no idea how they got 400, base 2 doesn't land on 400. Maybe 256 + 128 chips and they rounded to 400? No clue, I'd be curious to find that out myself.
I bet that ~112mb is probably shared video memory or something stupid like that. Everywhere I read has said 400mb though.
EDIT: it's 512, with 112 reserved for something that is not identified. Check the first couple paragraphs.
http://blogs.sonyericsson.com/products/2011/04/01/xperia™-play-hits-the-stores/
A lot of people here seem a little confused on what the Xperia Play has in terms of memory. I'll do my best to explain this without insulting anyones intelligence.
So the Xperia Play has 1GB of app storage which is basically the equivalent of hard drive space that a PC would have. This is used in conjunction with the SD card to store apps. It's also the same memory used for the OS. So it has 1gb of this memory, but ONLY 400mb is usable because most of it is used by the OS and bloatware.
So where the Xperia Play had 1gb, the DroidX has 8gbs. So really the Play has crap for storage.
Then on top of that the Xperia Play has 512mb of Ram. Everyone knows what that is, so I wont explain that. But this really isn't different from most high end Android phones.

@tornlogic- The Xperia play has dual channel RAM which is first in class and provides 2x performance boost to normal ram. Its the quality that matters, not the quantity.

This is where people are confused. I said that the Xperia Play has 512mb of Ram which is what most highend Android phones have. And that's great! I mean the Bionic will have a gig, but who cares? So why would you tell me quality matters not quantity when I said that 512mb is fine and dandy?
Its the 400mb of user storage, which is NOT dual channel I have a problem with.
Think of the 400mb storage as the phone's hard drive. You can throw the sd card in the trash, and the phone will work just fine. You can still dl apps, save photo, documents and whatever your little heart desires without an SD card. Its all stored on the 400mb of space Sony thinks is a lot, but actually isn't.
Again, my DX has 8gb of storage. The Sony has 400mb. Both phones have 512mb of RAM, with the Sony having dual channel RAM, NOT dual channel storage. Clear?

Lol, see now I was the one confused, I have seen the 400mb number quoted as the ram on many websites, I think even engadget. But that makes much more sense now that it's 400mb free NAND after the system image. Something wasn't matching up right with the numbers.
Thanks for the info about the dual channel ram, I didnt know that either.
This is the 4th time I've opened my task manager today and realized I was using over a gig. It easy to use over a gig when its there

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.

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.

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"

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.

I have to blame both device and OS....I am running ICS on my GS2 and have not even seen the slightest difference.....although my battery is just slightly worse.

You must be running some early leeks cause some of my phones like the GS2 and the evo 3d are running ICS flawlessly.
Hi guys.
I've been quite bothered by the fact that 4gb ram phones coming up, so I decided that I would do a test on how my LG phone handles the ram. I hope some experienced android users can clarify this for me because the only other android device I've had is a android tablet which I've played quite a bit with on my own.
I thought I wanted to do a stress test to see of the device would lag after having used all available ram. Problem is just I wasn't able to use all ram even with over a dozen open apps and so on. While I now have clarified that more than 2gb of ram really isn't needed ATM I would really love an explanation of why I wasn't able to get below 400 Mb free ram. When using the device normally I occasionally see only 300 Mb of free ram. Anyway the device was still working smoothly without lags and stutter

just the way android ram works really. Its different then windows, where no free ram means performance issues. Like no free disk space on Iphones.

Hey guys,
I wanted to ask if there is a benefit in having 8gb of ram instead of 6? Is it even possible to use that much on a phone?
All I've read till now was that developers could fill it with something but I can't think of anything. So I'm just asking out of curiosity.
I don't want a comparison of the 6 and 8 gig RAM versions of the OP5. It's really just about the 8gigs of RAM.
Thanks in advance

OP5 is so far one of the fastest phone you can ever get. You can't make it lag. I hope I answer even a slight part of your question.
I don't think the phone being fast is related to the amount of RAM.
Apps will eventually start consuming more resources and 8GB RAM will become a necessity in the future.
You can survive with 2 too, but 4 seems to be the standard now; next year 6 and in about 2-3 years 8.
Just depends on how well the phone can manage its own memory. But by default some stuff like mobile games take a lot of ram. Upwards to 400-600mbs of ram for just one app. Maybe just cut down on those or just accept that your device cannot keep everything in memory. Its ok to reload apps that are insanely big.

Like I had already mentioned. It wasn't about the phone.
I do have an OP5 myself ^^
It was really just about the huge amount of RAM
But thanks for your answer anyway ^^

I've heard that there are minimal difference between the two versions of the phone.

RAM is the only difference. Multitasking is better on the 8GB model though.
you phone will suffer from low cpu speed before ''needing'' 8gb of ram for 1 single operation.
Having multiple app running in the background makes the experience more fun, but the phone loads app fast enough anyway.
In fact, I'm using greenify, so no need of 8gb.
And a lot of cell phone user will change their phone before it will come slow, or really need 8gb. see pixel2 thread, a lot of people thinking about changing to pixel, what a waste...

more RAM = less loading.
this saves you time because the app stays loaded in RAM (no processing). this saves battery because the processor isn't having to work every time you open it. with 8GB, i almost never close apps.
It is easy to say that the more RAM you have, more the OS will use it, and this will make it more dynamic, therefore faster. But I think this is not perceptible for the user.
I have a 8 GB version and the device gets 5GB RAM to boot up... this would not happen in a 4GB RAM of course but this extra RAM usage do not reflect to more speed in a way you can see it...
The RAM management is more affected actually by the SO itself. I never use more than 7.5 GB RAM but my games never stay in memory for more than a day. I think OOS shuts them down after 24 hours not being used.....
This is a much more technical perception of how the device handle 8GB. I think its more a future proof quality then a advantage in todays processing.
