Xperia S RAM customization on Custom ROM Needed - Sony Xperia S, Acro S, Ion

i am currently using advance stock kernal but still the ram allotment is 635 i dont want z ram all those stuff as i need more ram when os can also take some space which is fine as the reserved ram is not used at all taking more space in the alloted memory still
I want a custom kernal which can allot atleast 750mb of ram to user when loaded as usual it take 350-400 still i have 350 which is fine for me.
But reserving some ram and not using to the core is not acceptable.
As many other companies does the same and they know 30-35 for OS and rest for user but i can see even xperia P it has 800 mb ram to user visibility and in Samsung galaxy s3 897 mb ram why xperia S along having a different setup. Dont tell Hardware reserve its not acceptable.
I would appreciate if any one guide on how to modify the ram .
Also i dont want any surprise that xperia doesnt have 1gb ram.

Those RAM you don't see is reserved for the rest of the device, specially GPU.

[Q] Kernels, Phone Setup, RAM, Scripts

Hey guys!
I noticed in the specifications of this phone, it claims to have 0.50gb of RAM (512mb) However all your kernels are around 370 of under?
Is this mistake in the specifications or are you lowering Ram for some strange reason unknown to me?
I'm using liquid smooth build#2 at the moment, but i'm only getting around 99mb free Ram.. I don't know why but it seems the Phone has less Ram then i initially thought.. However, i don't have any scripts going at the moment, i don't need battery, so any " and it's good on battery " will be respectively ignored.
I have looked around but not really found a decent enough set up for this phone yet.. Can someone please recommend me a kernel for 4.2.2 which is fast, and responsive, but also one with good Ram?
And can someone recommend some scripts worth using with this Phone? Again, don't go on about battery or SD life or phone life, idc about it, it's a spare phone..
Thanks in advance guys, could you provide me with links as well if it's not too much trouble? I prefer being directed straight to the point so i don't end up using the wrong Kernel/script..
Edit1: I'm not changing Rom. At all. unless you get an updated Carbon or 4.3.

Seems noone is willing to reply, but this probably because some searching and logical thinking would answer your questions. So since you are not willing to do it yourself others don´t mind replying to you.
So well I don´t use any scripts but regarding RAM size think about it. If you buy a PC with lets say 2GB installed RAM. Will you get also 2GB free ram by running an Operating System on it?

If you were to purchase 2gb of ram likelyhood is you will recieve 1.59+- usable Ram, free Ram would be totally different, however the way it was presented, and the way i portrayed it was thet the Ramdisk of the kernel was at 370+-, rather then 512.. I'm using a Desire C, which is running CM10 with 300mb free ram, with a 512mb ram disk, whereas with hurtskys kernel 3.0.x i get 99mb free? on 4.2.2 on my golfu i got 270mb free ram, and that was a Rom of 250mb+ and it's only at 767mhz.. yet seems smoother then the SGW? :s On paper it should be the other way around..
dun think u should worry about free ram.
android is based on linux, linux memory concept is different from other OS.
it something like " free memory is waste memory".
memory is always filled and hold so tat it wont waste time to reload.
if need more memory, system will free memory for other usage.
maybe this will help explain better, http://www.linuxatemyram.com/

You should first read what a ramdisk is. https://wiki.archlinux.org/index.php/Ramdisk
The 270+MB in hurtskys or my kernel is the real RAM aviable. The rest is reserved for the ROM, camera, drivers and processes to work correctly.

[Q] 2Gb Vs 3Gb RAM

Hey!
Would like to know if it is noticeble the difference between the LG G3 the version of 3Gb of RAM from the 2Gb of RAM.
Any one have tested or know?
Thanks.
G3 uses 1.5 gb of ram at all times, so if you get the 2 gb version itll always be pretty close to the ceiling

'One' of the main reasons I got the G3 was that it has 3GB ram. Most modern phones are pretty similar in terms of speed but memory makes a big difference. You can get by with 2gb but 3GB is much better and makes it much more future proof.
If you are using dual window for all apps through the little mod, you are less likely to have issues with running low on memory.

Currently it doesn't really matter - Android 4.4 requires only 512 MB.
The reason why a device with much RAM shows a high RAM usage is that Android considers empty/unused RAM to be wasted. As long as there is RAM available it will fill it with apps. It doesn't require additional battery power to keep a currently unused app in the RAM, it even saves power (and time) at the app's next usage because instead of loading the app it just needs to shove it to the front.
There is a defined amount of RAM that is kept empty for instantaneous usage, but everything else will get filled - provided that there are enough apps to fill it with. Android's memory management keeps track of your app usage. Apps that are used regularly get a high priority, seldom used apps a low one. If the system runs out of memory it will close low priority apps, beginning with those that haven't been used for the longest amount of time.
The only difference between 2 GB and 3 GB is that more seldom used apps can be held in the RAM. Under normal circumstances you shouldn't be able to tell the difference between 2 GB and 3 GB. About half of the devices shipped with KitKat still only have 1 GB.
Android L will probably require 1 GB - and with the 64bit support it might even result in devices with more than 4 GB of RAM. But that will be just for marketing, not because there is a technical need. Same as now with the 3 GB devices.
But I have to admit: I am a sucker for specs as well. I think about buying a G3 and since the surcharge for the 32 GB flash and the 3 GB RAM is only about 10% if will most likely go for the bigger one. I try to hide being suckered with the argument that 32 GB of flash are a lot better than 16 GB. - RAM? There is a difference in RAM sizes?

Reported memory on Xperia M5 - ONLY 2.53Gb - NOT 3Gb??

Hi all,
Hopefully not another self-inflicted silliness.
Is there any reason my unit does not report 3Gb of RAM?
You'll note that this is not just a 3000/1024 Base 2 type issue.
see attachments for info.
Yeah, I just noticed that too on my M5. A little investigation shows that the device includes 512MB of zram. So apparently the 3GB that is advertised is 2.5GB RAM + 0.5GB zram, not 3GB pure ram. I'm feeling a little cheated right now.

That's not cheating, it's just how the stock firmware was designed. Xperia M5 does have 3 GiB of RAM, but on stock firmware Sony decided to allocate 512MB of that to a RAM Disk, that's why you see only 2.5GB available. And that's actually a good thing, you can hold more apps in background that way, if the phone ever runs out of RAM it would just move some apps to the compressed RAM Disk instead of killing them, at cost of a slightly delay to go back to that app (CPU takes a while to compress/decompress what is stored on that RAM Disk).
A custom ROM could disable the RAM Disk entirely to make all 3GB of RAM usable or you could also compile stock kernel from source code to disable the RAM Disk too (so you could get all 3 GB available on stock ROM), however that would need an unlocked bootloader and thus, some proprietary features would cease to work...

But, 512MB is the disksize of the RAM disk. Zram is compressed, so the actual RAM used is smaller. Right now, on my M5, with the zram fully used, the compressed size of zram (from /sys/block/zram0/compr_data_size) is only about 120 MB. 2.53 GB + 120 MB is only about 2.65 MB. There's still about 350 MB not accounted for.

So? The actual size of zRAM varies depending of what data get stored there (some data can be compressed more or less than other), and you're still not taking in consideration that the kernel itself allocates some RAM to it (all Android devices do that). In other words, you'll never get 3 GiB of usable RAM. Want some examples? Xperia Z2/Z3 also have 3 GB of RAM but only up to 2.76 GB can be actually used (and that would be even less if they had a RAM Disk like Xperia M5). You can also go to GeekBench or any other benchmarking app to see the results by yourself, the usable RAM of a given Android device is always less than its advertised RAM size...
Thanks both.
I might expect that 3Gb might actually only be 2.76Gb if they installed 3e9 rather than 3x2^30.
But are we saying therefore that the M range uses a zram drive and the Z range does not?
How can we check what the maximum zdrive setting is on this phone? There used to be a Google play app call zram status, but the Github version does not work on my phone.

Xperia M5 does use a zRAM Disk. Xperia M doesn't. Can't say anything about Xperia M2 and M4, didn't own those devices...
About Xperia Z series, I can confirm Z3 and Z3+ does not use a zRAM Disk. It's probably the same thing with Xperia Z2 since both Z2 and Z3 are very similar and even share the same firmware build number (like Z3+ and Z5 too)...

How to increase Internal,Ram

Hey guys I have a Xperia s running on 6.0.1 aosp ROM...it is rooted and repartitioned ...can anyone tell me how to get the complete 32gb and 1gb ram coz the custom ROM has eaten my 3gb internal and I need full 1gb ram ..thks
Have you ever used a computer before?
The OS needs resources, it's a piece of software after all. The GPU will, in turn take some RAM, as it's not exactly a GeForce with dedicated RAM.
In other words, the only way you're getting 32 GB and 1 GB of RAM is if you uninstall everything, including the OS. Good luck doing anything with it other than holding down some sheets of paper or balancing a table.

OP3 use of RAM memory

Hello, i recently bought a One Plus 3, basically because i wanted to have more RAM, but i noticed that even though i have like 6Gb of Ram to do whatever i want, the phone uses with nothing open like 1,5Gb of RAM, the 500mb of RAM doesn't bother me because they come from apps i usually use, but the fact the launcher itself uses 1Gb is like way too much, i come from a Galaxy S3 with less than 1Gb of Ram and the TouchWiz laucher which is heavy only used like 400-500mb of RAM why is this? I know the easiest answer would be that the OP3 has more things, but do we really gain a lot more of functions that justify this heavy use of RAM from the launcher, or are we looking at not-well optimized launcher?
well your gs3 couldnt really use 1gb of ram and the oneplus 3 can. easy as that.

that means the OP3 is not as well optimized as the touchwiz?
No.. GS3 runs older OS like kitkat but as OS Improves they require more ram OP3 is now on Nougat which is amazing so duh... It needs more ram
Unused RAM is wasted RAM. As the OP3 has 6GB of RAM, it can allocate more RAM to certain apps and the launcher to ensure that nothing is closed in the background and everything runs smooth. Don't worry about RAM usage. For example if you launch a game, the game will then have priority to ensure that it is allocated enough RAM. Android is smart in its use of RAM so no need to worry.

That's why we have 6 gigs of RAM. Think little bit. They can use it as we have it. Pretty simple, right?
See its similar to methodology as if you you have larger space on bed you will occupy more space, similar to this when you have higher ram allocation to particular app is continuously decreased and increased so if no other apps are running allocation to your launcher will be higher to give it a smoother operation but as you start opening more ram hungry apps the allocation then decreases allocation for uelr launcher and allocate it accordingly
Go check how RAM and RAM management works.
It's kinda pointless to waste time explaining something here if you lack the basics about this topic.
Long story short: the more you have, the more will be used. Take the same desktop OS, install it on machines with vastly different RAM capacities and you'll see different RAM usages.

The more used ram the better, at least in vast majority of scenarios
