[CM][RAM] - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Guys, we all know that CM roms are far better than what touchwiz had to offer... but I saw a thing which amazed me.. cm roms have very low apps compared to touch wiz.. but the touchwiz had more RAM availability than the CM
CM - 778MB
TW - 862 MB
--
Ain't their a way to increase CM ram availability to the user

What's the problem? I don't care about ram until phone is smooth on cm.

I'm also want to know about that.. perhaps is the kernel... but if someone who can give a clarifing answer would be apreciated.. ..

Yes it depends on the kernel you are using.

which kernels provide the maximum overall RAM availaible?

Haven't tested much since JB was out but on ICS, hydracore kernel used to make a lot of ram usable.

Yeah you are correct!

Unused RAM ist wasted RAM. Rom/Kernel are the "people" who should handle resource management - nothing that the user should care about - especially not in the way: free RAM as much as possible.

It's not about how much is used and free ram. It's about the max available for use out of 1 GB that note claims to have.

@ThaiDai you were coming out with your cm10.2 rom? if you do.. please try to avail as lot of memory as possible!

Less free RAM after v20 GB upgrade

Anyone encounter the same issue? Used to have around 180mb before upgrade. Now most times less than

Not less than 100MB but also less than with Froyo.

Get a task manager and kill some tasks then, after killing tasks and only excluding stuff i need, eg. messenger app, music ect i get 205mb free ram and never go below 100mb.
I did still?at most 120 only.

Because your phone slows down when it gets below 100mb, don't bother arguing that because i know from experience that my o2x slows down and becomes choppy when the free ram goes below 100mb, because there is so much crap stored in memory.
If i need something to run ill run it and leave it there and exclude it from task manager but other wise its no use.
Its also a huge battery drain to have so many apps running that you are not using so that's a pretty stupid statement...."free ram is waste ram" lol wtf...., your battery life must be really long.
As for OP, i suggest you install a better rom, i use topigigis 1.7 rom and after killing a bunch of tasks i get up to 205mb free, altho this gets less the longer it goes without a reboot, so try rebooting and hen killing some useless tasks and see what your ram level is at.

Free ram is wasted ram. And taskkillers will only make you battery life worse if not some app is using all the cpu. The reason RAM is used by android is to keep apps preloaded, for better launch times. The built in task handler is all what is needed. My phone runs blazingly fast at all times, and I don't use a taskkiller.
yupe.. Mine is mostly below 100mb.. 70mb on average. but it's smoother than froyo with 140mb.. list of applications and files are faster to load and smoother.. so i have no complain at all.
I'm also experiencing the lower free memory in the default configuration with GB compared to Froyo. Although I'm not trying to get as much free RAM as possible (because I support the reasons given above for usage of the RAM, having apps in there doesn't mean that they're running) I'm still curious where the missing amount of memory went... Does anybody have any clue what was introduced or changed with GB that could use up about 70MB?

Clearly you've been on cm7 so long you forgot how bad stock is..
Stock firmware for my phone was horrible and backgrounding was working for only seconds due to lack of ram, Opera would never background, always a new boot.

I m on stock v20 ROM. Sometime my fone will b sluggish and it seems like e low RAM is causing it. Also wondering where e RAM went After upgrading.
use supercharger
Code:
http://forum.xda-developers.com/showthread.php?t=991276
And there's a bug in original stock kernel about memory management, horse power kernels are better for that.
Its not just about the rom your choosing its about the kernel, flash a good kernel and it will improve memory usage.
So does flashing custom kernel void e warranty and does it need rooting? Which is e best kernel for stock ROM v20?
Thanks

Yes most of the time and Yes. Some providers accept phone customization in warranty, ask yours.
If you have v20L you only have Horse Power kernel (Neoblaze seems bootloop) + Power pack 7 (mandatory, orbootloop, see dedicated threads).
If I reflash my phone using one of the original images availabe and reset it, is there any chance for the provider to detect previous flash operations?

I'd tend to relate the better battery life to the new kernel than the increased free ram. I'm on RC9 (w. PP7, no init.d-scripts) and my LGOS reaches almost two days of battery standby with ~50-60MB free RAM.

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.

Im typing using my optimus one running icss.
NOTE: my phone can only be over clocked till 729mhz.
So for our 2x it will be no prob.

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.

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.

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.

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...

KLP Custom ROM for our SGSA...?

Will we have a Key Lime Pie Custom ROM for SGSA once its released? Just very curious about it
I am putting this thread here because I think this should be a general discussion where everyone could share their thoughts/development plans.
Don't get your hopes too high,If 4.3 Jelly Bean can be ported as a custom ROM because of similarity,I don't think KLP will ever be on this device,only if STE releases the sources,which is improbable.
It will be possible only if STE release sources. Now we have their pre-built binaries from our stock jb and devs have difficulties making them to work on aosp 4.2. Almost no chances in making them working on KLP because our libs where made for 4.1 and we don't have their sources to modify them according to newer versions of android.
*generic signature*
The reason why we don't get 4.2.2 is because RAM consumption, even with CM, that uses way less ram than stock rom. Now, if CM10.1 uses less RAM, and the consumption is still high... Imagine on stock...

What are you talking about? Now with the buggy settings app, which takes up 60mb+ ram, there's still 380mb ram free. Without any app killing, or "ram freeing" what you would do on a stock rom. Stop talking nonsense. And btw, cm10.1's ram management is completely different than a 4.1.2 stock rom's... you won't run out of ram, except if you run an app which requires 600mb ram..
Edit: After opening: dialer, messaging, browser, clock, and camera, there's still 368mb ram free (in the settings, so count that in..). So what are you talking about?

I think RAM is not the real problem on our device. There's plenty of free RAM even when multitasking, and also Android can instantly clear RAM when needed in order to open a new app.
Some rumors I heard say that Key lime pie will a quite light OS, so it will be able to run even on devices without a big hardware.
The real problem IMHO is ST Ericsson not releasing source codes. Samsung will likely not release official 5.0 for our device, and we should rely on developers, but I imagine it's hard for them to port a 5.0 based rom from other devices without source codes.
KLP=Android KITKAT=CM11
Just search the cm 10.2 thread of team canjica's for cm 11 and there will be a post by the developer about CM 11 being under construction.
Also the Android KitKat is considered to be able to run on older devices with atleast 512 mb ram and 1 ghz dual core and having met the requirements by s advance,maybe samsung will release stock 4.4(KitKat) by next year but we could taste it with CM 11 being ready by january(IF).
I am bad at smileys.

RAM management with CM13

Guys, who have already flashed cm13 on their device, how is the RAM management.
I know its AOSP RAM management but how much free RAM are you getting on 1st boot?
Also is it able to keep things in memory like games and browser tabs?

I honestly don't know, I've never monitored free memory since using devices with more than or 2GB of memory (Nexus 4).
And I don't think it even matters.

On CM13 here and can keep about 1.5, 1.6gb free. But, multitasking just work! When I was on MIUI every time I must reload the app... Now I can hold apps and some games. I recommend CM
Multitasking work better than miui, you dont need more free ram, as long as system didnt lag, all working fine on cm
