hey guys.
today I installed resurrection remix v3.0.5 on my friends s2. in the aroma installer I selected to install the stock CM10 kernel.
then in about phone, hardware info there was listed 825MB RAM!!!!!
and we also have 1GB ram, and here with us we have only 678MB RAM available...
so both phones have 1GB ram, and yes I know a part is OS reserved, but why needs the GN OS more ram than the S2 OS?
Free ram is wasted ram.
My wife also have s2 and same rom as you say(....remix) but not fast as my GNex on stock firmware.

I find it's best not to worry about RAM in android devices. Unless you're actually seeing decreased performance.
It just so happens that our chip set had one of the fastest RAM speeds when it released.

It matters about how much RAM we have total

The ram missing is used by the GPU. 698 is whats available to cpu

This doesn't answer your question and will probably add more confusion as to why we're missing so much RAM but I think Android Jelly Bean uses more system RAM.
Fast forward to 1:47. You'll notice that CM9 leaves us with 829MB or memory and CM10 gives us 693MB. http://www.youtube.com/watch?v=MIQO_kRFLwQ&feature=related
no more care about the ram.use the GN fast and comfortable is the best.

Do your own build with tweaked settings to have "more ram". We could even set it to say you have 900 exobytes of ram if that'll make you feel better? To be honest you shouldn't even be concerned with it. Is it causing problems? No. Android has its ram situation taken care of just let it be and go on with your day.

Because your friends s2 screen is only 800x480, so the gpu only needs a small amount of ram dedicated to it. The gnex has 720p display and requires much more ram to be blocked off to run the display and gpu.

It was well understood but it has just been asked 800,000 times on every device and could easily be discovered with a search.

I had the SGS2 as well and had about 835mb free and was surprised that that the GNEX only had 695mb available. I don't really believe that in order to support 720p, the GNex needed another extra 140mb reserved. Probably reserved for something else.
On the downside, the GNEX does not multitask as good as the SGS2 because it lost the extra available ram.
Every 3rd app in the background seems to get killed whereas on the SGS2 even the 5th app resumes fine from previous state.

Depending on the version it may have more reserved for lte baseband. Things memory are reserved for are baseband, GPU, camera, multimedia decoder, etc. Probly got 128mb or so for GPU, then the other 200mb go to baseband, multimedia decoder, camera, and whatever else.

No they probably just haven't tweaked kernel memory settings yet since its still in early development. Cm10 is just started development and cm9 is in release state and cm10 does not have all changes merged
Edit: Also it may never have same amount as the s2 as Samsung configuration for memory is gonna be diff because of the diff chip. The omap soc may need more memory dedicated to it for one reason or another.

CONFIG_ION_EXYNOS_CONTIGHEAP_SIZE=71680
total reserved = ~200mb
simply put samsung reserves less ram for system in the S2
The S2 uses less GPU memory for sure (almost 1/2 of the GNex's) and overall less is allocated to the system
also i will say it may depend on the kernel your running because My GNex registers 694mb ram with Franco kernel just fyi
if you want less things to be killed off then set your ram settings to be less aggressive so it will keep processes for longer periods of time
It's my understanding that this phone comes with 1gb of ram... Why is it that at any given time only about 350mb of that is free to use, and only 768mb is available total? I realize the OS needs ram to run, but I can't imagine that it needs ~600mb.

I want to know as well, the lowest I get it is 326mb with easy task killer,
I assume 768mb available is just what they give us, it's always less than advertised.. but I dont understand how on my last phone there would be 100mb free but itd be running like.. ****

I believe a certain portion of your RAM is reserved for system devices like Radio and isn't seen by the Android OS.

I noticed this to, but if you ever had an older Gingerbread device, even running CM7 they came with 256-384mb of Ram. By the time the phone was booted and all the front end services and apps were loaded, you had roughly 90mb of free ram to play with. I heard ICS and JB would at least double that, which is in par for the 768 +/- Ram usable. With a custom ROM, and removed bloat, I have close to 500mb free at boot time, so still a lot of front end apps are being loaded and using that Ram.
I think this is why a lot of older devices, even with 512 ram had a hard time getting an ICS update. Processor wasn't really the hardware in question, but moreso the Ram.
I hope this makes a little sense since I'm still half a sleep
Remember that android loves to fill up your ram with your apps for quicker launching. Android actually runs worse when you have free ram. Go into developer options and limit background processes to 0 and see for yourself lol

Can someone tell what is the exact RAM that we get on S3. I have noticed that it was 1.65 GB (when I first took notice) but now it is 1.56 GB.
I am rooted and running official JB Stock.
Please reply guys,it's giving me sleepless nights.
Thanks in advance.

I did search but my doubt is, it was 1.65 before then it got reduced to 1.56? Is it normal or anyone else noticed this ?
And also was it only 1.56 from start i.e out of box.
Its 1.62 GB on mine running ICS

mine is 1.56 on JB. This is the reason of my dilemma and posting a new thread.
Update to JB man..it's superb
I also have 1.62
My suspicion is that the os reserves a little more RAM in jb than ics...0.44 of 2gb reserved in jb vs 0.38 of 2gb reserved in ics. It's just different allocation, the physical amount can't change.

now i can sleep in peace..a friend of mine told me that rooting decreases RAM although I have rooted my Galaxy S and used it for 2 years i never noticed this but when he mentioned I noticed that the RAM amount was less (1.65 gb compared to 2 gb I didnt know about this ram allocation % )and even more shocker was it decreased after I upgraded

Hi guys! I ordered my SGA 2 today and it probably comes with GB, so i was wondering should i update it to JB? Some say JB lags in SGA 2 and others say its better with JB. Could u tell me ur experience with GB and JB in SGA 2? Question is: Should I?

In my opinion jb is in many ways better than gb, besides the battery life. however I've found the stock roms to be laggy but when you install one of the costum jelly bean roms that problem is out of the way too. So I suggest u upgrade to jelly bean, I think it's really worth it! p.s. next time post your question in Q and A for ace 2 thread, it's there for a reason!
If JB only CM.
So basically you read on our forums that for some people JB lags, for some not, and then decided to open new thread to read the same things once again hoping that maybe now everything magically works fine for everyone? Both sections are full with opinions and threads on every available release of JB, we have also Q and A section to ask such questions there.
Android lags every time. I have LG with Quad Core Tegra 3 and I see lag. Same with any other device. In other case, Lumia 720 is running flawlessly. Why? Not open source and full of ****. In any case, I advise to install ME7 Android 4.1 to Ace II. Better than GB.

CM is buggy and luggy)))
I use JB since the first release and I never again had a thought to revert back to GB. Current JB roms are quite stable, so there's no need to stick with GB. Just don't use CM or any other rom which is in alpha stage. Wait for stable release and you'll be okay. And to answer your question - Yes, you should upgrade to JB.
I ´m using JB XE7 since 10 days and it´s working fine ! I update from GB straight via odin and got 624MB memory. For me, i won´t go back to GB!
JB Looks a bit too boring to me... Yes it has better battery use capabilities and 'new' features but for me... ICS is my personal pick. But I would choose GB over JB any day

GB over JB any day for me.
I have flashed all JB release except MF1. All roms were giving too much lag when playing a video (play and then go forward or back and your phone might even become unresponsive) and youtube and facebook videos especially high resolution videos. I have tried Italian Job over MC8 and Kyrillos over MB4 (or MB2?), they were better than stock but not close to how GB plays videos. GB is best for SGA2 in my opinion and experience.

Man, clean RAM sometimes with dedicated Samsung app. I have ME7 and everything fine.
Gb maybe a bit faster but jb is very stable if u install a good custom Rom. Try the italian job rom by mkel91 the nature ux version or kyrillos v8. They are both good but i feel that italian job is more stable.
Plus jb is capable of running a lot of apps that gb can't and don't forget that BBM will only be available for devices with ics and up
If u need any help installing roms just ask

So my own experience is
I had installed GB and was happy gaming Performance was ok but for exemple blitz bridgade lagged a lot at low grafics on Gb then i went to mb4 and mf1 and i just can say AMAZING my phone is much quicker and the gaming Performance is very good for exemple mc4 mission 1 crashed on Gb but works on jB same with gangster vegas so i just love mf1 ; D

I do believe Jelly Bean is better, it may be slightly slower at some stages but the touchwiz UI is so much clearer and more advanced. I bought my SGA 2 back in november with GB, and got impatient with o2 not giving an update for it so I decided to root it and get Bagnz0r's sakura droid project on it. I prefer the AOSP look overall
i prefer JB
I use CM 10.1 from bangz0r is faster then gingerbread and more stable.
Has someone made a GB ROM for the gnex? I bet it would be wicked fast and smooth compared to other ROMs with higher Android versions. Is there anything that holds it back from getting GB?

No, Even with its bugs, Kit Kat is much more optimized.
There are probably no drivers for it anyway.
You are not the first one to ask this question. Short answer: no.
Long answer: as of now there exists no known build of GB for gnex from anyone, since there is no blob and driver available from Samsung and TI to build GB on gnex. It will run fast, but not that much comparing to newer Android builds because of the lack of optimization at that time.
Don't forget the fact that 4.1.2 was probably the fastest for the GNexus, then again there's a ton load of optimizations that are needed to be done, then a massive downgrade to the camera drivers and chipset. Besides it would be a waste of time as there are a lot of restrictions and limitations. App support goes down the drain as well, you can kiss goodbye to all those fancy animations or superbly optimized launchers like Nova.
Also the only reason it will be fast is because of the scaling option is really low res compared to Jellybean/ICS.
I'm not sure if you really thought this through but it makes absolutely no sense to do so. It's like buying an i7 with 16GB RAM and high end graphics card... And then you install Windows 95.

Your understanding about the OS is miss leading..
GB is probably 'heavier' on any Android phone due to worst memory management compared to ICS and JB (also depends on the hardware).
For example, my dad's Galaxy Ace 2 running smoother on JB 4.1.2 than on GB. Why? Because JB eat less RAM to run. KitKat supposed to eat lesser. Meanwhile my brother's Optimus One runs at best on ICS (first came out on Eclair, updated to GB officially), but really slow when it run on JB (the hardware won keep up).
BTW, I agree, JB 4.1.2 was the fastest on GNex.

If only they hadn't picked Omap as its chipset, probably it would live to see another day. A year in and the company closes down. I don't know if they tried to save the company thinking adding it on a Google phone would redeem the company, instead the GNexus was one of those poorly advertised phones, where only people who kept up with the Google trend or xda/root wiki knew about the phone and what it was really intended for.
