Full 512 mb available?

Does the froyo update make the full 512 mb ram available? I had heard earlier that only a part of it was available due to 2.1 limitations.

They were always available, ~300Mb for Programs and the rest for the system files... Why should that change?

I think what the OP meant was whether one had more memory for apps as ht tp:// developer.android.com/sdk/android-2.2-highlights.html claims that the 2.6.32 kernel upgrade would bring "HIGHMEM support for RAM >256MB".
At the moment, we do not have the full memory available in the Linux system:
Code:
$ adb shell
* daemon not running. starting it now *
* daemon started successfully *
$ free
total used free shared buffers
Mem: 333420 329988 3432 0 34724
Swap: 0 0 0
Total: 333420 329988 3432
I do not know whether that is related to the graphics hardware taking some of the memory, or to the kernel version:
Code:
$ uname -r
2.6.29
Edit: What do you mean by 'system files'? The OS is stored on mass storage, right? And Dalvik and friends should appear as userspace processes taking up regular memory.

You do understand that this does not compute, since there has always been more than 256MB available
Or has there?

I was wondering about the same thing, kernel 2.6.32.9 (JP3) also shows a little more than 300mb...

Hey, I'm just quoting from an official AOSP site

Mine shows 30 mb available under advanced task killer. What am I missing?

I've seen Desire have over 400MB of memory available for applications in a video with a some sort of task manager on..

Are you sure, max i got on my nexus one was 312MB in some rare cases, using it without closing apps at all, never got below 100MB... But my Galaxy's max is 170MB, is almost half what my nexus gave me, that kinda suck (don't know if it matter bu tit feels bad in my head )

Desire has 576MB memory.. N1 has 512MB

Maximum free RAM i got from my sgs is 210mb, easily achieved by using Astro's process manager and killing all non-essential services.

why t.f. do you guys always want to have lots of fre ram? please read a little about android memory management... free ram is wasted ram!

So? We all still want our phones to be as future proof as we hoped they would be when we bought them. And we want the extra RAM simply because it's supposed to be there.

As long as it doesn't go below that ~70mb when the phones actually start lagging
Might also want to take into consideration that the counterpart Desire used in this thread is also an android phone, sure too much free memory is wasted memory but too little usable memory = lag and if there isn't a lot to use in the first place then it won't take much for the phone to start lagging.
Some help in JG and onward firmwares but it's still quite funny that a simple user can make a fix to create a solution for the entire problem and Samsung hasn't either thought about this or taken it into consideration. (Mimocan is my hero <3)

Hey,
Actually you do not need that much RAM. Im running on JG5, which IMO is the most stable and usable firmware out there. Has been running the phone for 3 days straight without any ATK like apps, and has not experience any lags.
Another thing is that, IMHO ATKs slow down the system.

The current Samsung froyo builds do not support highmem. It is a kernel compile time config option. Samsung will hopefully enable it in later builds.
Highmem made a noticeable difference in performance on my nexus one.

Nonsense. You are not entitled to more free ram in any way.
Every os uses a part of the ram for the kernel code and its buffers.
In addition the advanced graphics will need memory for its texture storage and graphic representation.
A froyo kernel will not make a major difference.
The sg has 512 memory today and it is using it as it should...

lagging is actually not caused by to less free ram, in android there is no such. the used ram is caused by apps that you opened and then exited again. if you open a new app that needs more ram than aviailable (actually with a little gap of some mb) the system will close apps that are not used anymore and only kept in ram for faster opening. the lag comes from bad i/o speeds of the nand (internal memory) where apps data is stored. on i7500 there is 192mb of ram and it works ok with froyo (thanx to drakaz and gaosp team!) only thing is that every app you open forces the app you opened before to be kicked out of ram what makes switching between apps makes somewhat a pain.
also free memory and usable memory is apples and pears, useable is all memory that contains no actually running in foreground app or service. and free memory is the rest that contains absolutely no information and thus WASTED
edit: btw i7500 is running well with 20mb free ram.

I often have no more than 30 MBs free, and not running THAT many apps. What is strange is that sometimes there is 70-80 MB free, and I have not done anyting. What happens in the background is a mystery... Any suggestions?

You can almost guarantee that a 1GB model will be better. The Optimus 2X does struggle with it's 512 mb, because 128mb is attributed to the GPU. Lukily, some kernels, like IronKrnl free some of that memory up and give it back to the CPU, but it's still losing 80mb.
Also, it's worth noting that, if you want to run ICS, if you look at the phones out that have 1gb of ram, you'll see they're all actually better phones- especially what Samsung make.
So, while the O2X is a cheap dual-core device. The best experience will come with something with 1gb of RAM, as it's much more likely to also get ICS. (Due in part because most 1gb phones have already had an announcement, and for it to be soon)

ICS is very hungry in memory. On my Asus Tablet running official, my 1GB RAM is fully used, as usual in Linux but at a higher level than in GB.
To run ICS correctly on O2X, you must use IronKrnl, the 48mb ramhack version is correct (means it steals 48MB to GPU, leaving only 80MB to it), and modifying memory killer values to a sort of aggressive profile.

Yea right, so this is why I had less free memory on GB. And now I have CM kernel on ICS. I doubt you actually tried CM9 alpha on O2X if you are talking crap like this about performance.

The browser in ICS works better even though we have 512MB. It always returned to where I had left. 512 and less is enough for full desktop environments on PC even.

See my sig and stop arguing. I run CM9 since first day Ricardo published SK0, and now running SK2 with latest Ironkrnl. Setiron himself admitted on Google+that ICS is a memory eater.

Dont know how much free memory we're talking about here but I'm on SK2 with original CM9 kernel. Using Adv.Task Killer from time to time and I always have around 200-240 Mb free memory. Just sharing my experience

Running CM9 aswell and its sooooo smooth, faster than any rom ive tried

OK, so what happens when you want to run Tegra games? (like Dungeon Defenders for example). A shame you cannot dynamically set the ram hack :-(

That's the real question... Free memory when phone is idle means nothing. Plus you have to consider the lowmemkiller values you have set, I personnally use aggressive values: 16 24 32 90 100 110 to free the most possible memory.
Many users report freezes with games that run perfectly on GB. The problem or ramhack is choosing the right value for gaming, it seems 48mb version is the best compromise. A 'on the fly' feature was not planned for the moment by Setiron in one of his G+ posts.

It does. In low memory situations ICS seems to keep running better and smoother compared to GB. If you get under 40mb free on GB everythings gets very slow, with ICS it seems to handle it a bit more elegantly from a user experience.

Please don't think I'm pesimistic here, I'm just going off the comments: Given that OEM releases tend to be bloated and memory wasteful, it's not looking great for an LG ICS release that is 'fully' working. If they pull it off and allow tegra games to run, then I'll be impressed

the official release from LG should be more efficient, and once you remove bloatwares, it should be quite a charm

Hi,
The Google Nexus S also has only 512Mb, and a certain amount of those allocated to GPU (though I don't remember how many), and ICS works like a charm on it... So I think it shouldn't be a problem on our O2X! :-D

It has the same config (128 for the GPU, 384 of available RAM) and works really fine.
Obviously a full gigabyte would be awesome.

Low free RAM on ICS

Hello all XDA devs and users!
I've decided to run a new thread becasue recently a few users (including me) had a discussion about low free RAM available on our ICS roms and kernels (different ones i.e. Infinitum + Devil kernel, CM9 and others).
What I have found on my devices after running a couple of days without restart I end up with 40 - 50 MB of free ram with Devil XL kernel (389 MB), where the other users with similar configuration have more than 100 MB.
I know that some of you might say, this is how the Android handles the RAM and that is good when most of the memory is consumed. I would totally agree with that however when there is around 40-50 MB left, the phone starts to perform slower and starting another app result in lags.
I do not want to use any task killers because what I have read, they simply do not work well with android (see rule above).
Maybe some of you have an experience or knowledge, why on some devices there is more than 130 MB of RAM left even if there are 8 - 9 apps running (i.e. services) - after couple of days and on some others there is only 40-50 and phone lags more and more.

Reboot the phone everyday when you're having a shower.

Thx for the tip, but I do not see this as a good solution. It's hard to predict when or how often the phone gets slower due to low Ram available.

Play some good games that require higher system requirements once in a while. You'll have a lot of free ram (around 200+ cm9 nightly).

That's the proof that RAM doesn't get consumed by the android system after a day or two.
Do you use any task killers or modification to your system?

You can flash Semaphore Kernel sbm, it gives 410MB of RAM, the HD recording gets broken but i think its a good sacrifice for a good performance.

Yes I can but the point is that the more available RAM will be eventually taken by the system at the end of the day. Increasing more RAM by the kernel will not help here. Right now I have Devil with 389 so only 20 mb less than with semaphore but still more as with the default kernel.

I notice this as well. You have to either run a Rom that includes a low memory killer, e.g. aokp. Or you need to use a kernel where you can set the lmk, e.g. semaphore. I think if you don't do either of the above, the default free ram is around 45-50mb. I am using aokp with midnight kernel at the moment, with free ram set to 75 mb free.

Ok i reckon the best way to improve RAM and system memory is by using this tweak.
I have around 120mb also and multitask around up to 4-5 apps without it closing.
I use ICS btw.
Ok go to google or XDA search and type supercharger, follow instructions and Wolla, U should have about 120mb of RAM all the time.
If that is to hard for you here is a simply method. Go to Play Store and type RAM manager (PRO). there is a free version but its not that good. Trust me the PRO version is way better, buy the app and use it!
It is really good!

THX guys for all concepts and advices!
After a couple of tests and research I've done so far there is one method that simply works perfect for our SGS devices.
No matter how much free RAM you push from the kernel (THX to all DEVS for BM kernels) we will not have enough free RAM for the hardware our phones have. I my opinion SAMSUNG simply f**** up here and gave not enough RAM for the phone that can act so fast and handle pretty resource hungry apps and games(
I have used 'Supercharger' script extensively when I was on GB Roms. It did pretty good job, nevertheless you always end up in the situation where more RAM is needed. In this case 'Android' (LMK) kills running or buffered apps to make new rom for the app you started.
Some time ago I have compared GS2 with GS1 against RAM. The key thing why S2 works so well is amount of RAM. Even if the system is loaded and RAM reserved for GPU and sensors the S2 has at least 500 MB FREE, which we will not have never...
SOLUTION:
The solution I have found (in fact it was not me, I simply started to using it) is SWAP. Recently one of the greatest kernel devs (DerTeufel1980) here on XDA published his kernel (Devil v0.79) with SWAP option enabled. If you create a partition or file with apps from Google Play store (like the pagefile in MS Win) you have more RAM (not physically, but still apps are being loaded into swap file).
I was doing some tests few minutes ago and got that:
- 10 tabs opened in ICS+ browser (each was unique - not Google search)
- Any.DO
- QuickAccess
- PowerAmp
- Snowstorm
And I could access every single app quicker than ever before. In fact I could not start 10 tabs in web browser not to kill launcher before or any other app I had buffered in RAM.
For those of you who are wondering if that is a good solution I can say that you should try it. If you do not like it will not use it and stay with kernel and LMK you have now.
I am happy with that so far and of course will do some more tests.

Autostarts
I use an app called Autostarts which you can purchase in google play store. What it does it stops apps from starting up on there own, you wont believe how many apps start up when they are not needed e.g - when you plug the charger in Google Mapps will start up in the background or when Wi-fi is switched on the calender will start up and run in the background, why??? i havnt got a clue but with Autostarts you can pick and choose which apps you want to start or not. I've used it for the past 8 - 12 months and i cant fault it one bit. I'm on AOKP Milestone 5 SGS at the mo and i always have between 170mb & 210mb of Ram availible because i stop uneccessary apps from starting up

i'm using ics with many running service as i can,and i never get lower than 80...gtalk,viber,Y!,any.do,gesture search,and so on...
1-first of all,try NOT to kill useful and auto restart-able apps like the ones u use sometime your widgets of course!;in my case it includes viber,facebook,any.do...
cause in every restart android lost a little of ram,and it cant recover that anymore
2-try disabling location service and force close google maps(if you've installed),it really helped me!
3-try "auto start manager" apps
4-use system tuners and tune ur ram auto kill levels.
i've tested many combinations and found 16,32,40,50,50,80 with GB 2.3.4 acting nice to me,but now i have 14,19,24,32,37,50 on ics 4.0.3 CGen.Mod and i had no problem so i didn't bother myself to test any other combination

Rebooting doesn't really help. Limiting background processes or ReChild's Advanced Task Killer as an easy solution. 400mb kernel and/or force closing/disabling apps, clearing cache if you know what you're doing.
If you're flashing CM9 nightlies every few days, you won't have too many troubles with free RAM.

[Q] about Galaxy Mini RAM Processing

Hi Guys
I have a few question about our device RAM
1. What are you doing if your device get lagging or slow down?
- Kill App using Taks Killer to refresh your RAM?
- Just Reboot the device to reset your RAM?
- Leave your device (LOL)
- what about you? have an opinions?
My Device get slow down while browsing after >20Min, I think the reason because the RAM goes down or less than 25MB.
then my device got freeze and reboot automatically.
I hear an issue about task killer app thats bad for our system.
so I'm using app like RAM Manager or Watchdog.
2. How much RAM are you running to get stable?
My device at startup have remaining about 100~125MB RAM.
and after a few hour its goes down about <70MB.
while browsing its about <50MB. this is normal?
how about you?
I'm Running CM9 (ICS 4.0.4) right now.
Its very stable, but goes crazy after RAM run under 50MB.
I'm need your opinion guys to make RAM more batter.
Thanks for your advice.
Sorry for my bad English.

If you are using AOKP, in performance settings there is low memory value, try adjusting it.

Never ever 'clear' your RAM, it will worsen your battery. Android is capable by managing the RAM by itself if it gets high. So there is no question whether the RAM meter would blow if it gets full. Read more : Article by Lifehacker

I tried to believe my device can control RAM it self, but in the fact after a few hour my device got freezing then reboot its self (This problem often encountered when browsing)
Thanks for the Advice guys,
I think the most problem it from our device it self, you know this is Low Device right?
so I cant expect much about the device
but I'll try to find for the best RAM tweak/setting.

Jelly Bean eats all of ram!!! Severe Ram problem

Oh, after using jelly bean for 3 days, i noticed that it eats all of Ram, only 60-110 MB free!!!!
And this cause very slow downs and FC alot,
While on ics there is about 200-250 MB Free!!! With the same apps
Is this bec. Of beta, running, and freezing all bloatware and the same aetup in every aspect
, is 1GB of ram isn't enough now days!!!
Again, i tried to use swap file using various methods with no success due to kernel support, is there any kernel or method to have working swap, or is there any workaround to have some thing similar to swap.

The note actually only has 800mb, so it's not even a gig.

well ram works differently on android then on windows pc, if its full it doesnt necessary mean that's why device is slowed down. Memory works differently.
Secondly jb, you are using now is not for everyday use. So you are bound to run into issues like this one. Also there is a memory leak in current builds. Which means that JB doesnt do that, but the current build does that because of a bug.

Secondly jb, you are using now is not for everyday use. So you are bound to run into issues like this one. Also there is a memory leak in current builds. Which means that JB doesnt do that, but the current build does that because of a bug.

Yes i know that full ram may not cause slow downs, well it will slow down only when riched critical value and cause FCs , but you say that this problem in JB is due to beta stage, so this is good, so we have to wait for fully working build or at least stable enough to run system without FCs or slowdowna

Yep definately.
I guess it takes extra clean installs with prenightly roms.
Maybe, because you got this far you can get comfortable with logfiles and troubleshooting. Try to get to the root cause of the issue. You might be able to contribute there.At this point if I knew how, I'd help you.

The note actually only has 800mb, so it's not even a gig.

Is that true? I don't think so. I think it's how it's allocated and counted. Like when you go buy a 1TB drive, you only have access to 931GB. It's how it's formatted and allocated.
Probably the same with Android with memory allocation or something like that. It's false advertising to say "It has 1024MB of RAM" when they actually only include 800. 800 is accessible, but there's probably 1GB in there.

There almost certainly is 1GB of RAM in there, but the graphics processor needs some of it to do it's job, say probably 128MB. Then just like the PC there are other other parts of the device that need to have blocks of memory to do their jobs, and the kernel and other core OS will probably snarf some memory to do what they need to do.
Voila, 1GB of RAM immediately reduced to 500-800MB of actual "usable" RAM.

Yup, the 1gb is a lie.. galaxy note has the same amount of ram of desire hd

No dear, desireHD has 786 MB BUT ONLY about 600 MB usable, the same story as note and every android device

Based on every nand device out there, ssd, emmc, all of them allocate sectors to general use.

Can part of internal sd or ext sd become an extended ram or something?
Would that make the device any faster?

Yes it can.
No that won't make it any faster. In fact, it will make it slower.
The way Android works is, it says "the kernel says I need X amount for gpu, X amount for sound, X amount for the OS".
And then it allocates a certain threashold and says "okay this much I'm keeping free".
Then it says "these functions of the OS aren't used often, I'll leave them out".
Then it says "okay so I've got extra ram room, I'm going to fill them up with Apps".
Why does it work this way?
It based on Linux, RAM is shared dynamically.
What does this mean?
A bloated kernel and OS will use more RAM for itself.
Why does it leave free ram?
In case it needs to execute a function that's not used often or is memory intensive (eg Browser).
Why does it store Apps?
So that its readily available. They just pop open. Or resume from last state.
...okay, so what does this mean about my Free RAM "issues" with Jelly Bean?
It means that you are uneducated. It means Jelly Bean, or the specific setup you have either is more bloated than your previous setup OR it has a low "free ram allocation" setting. Solution? There is no problem, though you can trim down the ram allocation and kill off some memory things (apps, hidden background tasks) you can increase the amount of Free RAM, but its more likely to slow down the system. Remember, Jelly Bean builds are still Alpha/Beta stage, so they can/do have memory leaks.
Another point I should mention:
OS RAM use increased a lot from 1.6 -> 2.1
OS RAM use increased from 2.1 -> 2.2
OS RAM use increased a lot from 2.2 -> 2.3
OS RAM use increased a lot from 2.3 -> 4.0
< I haven't checked JB, but I'm willing to bet its increased from ICS, even if slightly >
This is Android, not Windows. Its behaves differently and has different symptoms. A quick Google search could've answered your questions.

Thanks for the lecture here :thumbup: I see now, I never get to know linux base very well. Just starting to get myself familiar with it.
I've used a few types of JB rom before and I discovered that its using double the ram from ICS making my phone lags and does funny things ut shouldn't. Ahaks
Than I noticed that JB was released to phones such as S3 and such, phones that has double the ram size to compare with note. Its when I started to wonder...
