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.

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.

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.

here is accounting for some of the "missing ram" your referring to
#define OMAP_TUNA_ION_HEAP_SECURE_INPUT_SIZE (SZ_1M * 90) not sure what this is
#define OMAP_TUNA_ION_HEAP_TILER_SIZE (SZ_128M - SZ_32M) this is GPU and its reserves 128mb
#define OMAP_TUNA_ION_HEAP_NONSECURE_TILER_SIZE SZ_32M
#define OMAP_TUNA_ION_HEAP_LARGE_SURFACES_SIZE SZ_32M
#define PHYS_ADDR_SMC_SIZE (SZ_1M * 3) buffers for I/O?
#define PHYS_ADDR_SMC_MEM (0x80000000 + SZ_1G - PHYS_ADDR_SMC_SIZE)
#define PHYS_ADDR_DUCATI_SIZE (SZ_1M * 105) no idea what ducati is? baseband?
#define PHYS_ADDR_DUCATI_MEM (PHYS_ADDR_SMC_MEM - PHYS_ADDR_DUCATI_SIZE -\
OMAP_TUNA_ION_HEAP_SECURE_INPUT_SIZE)
total reserved = ~300mb
and here is S2
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC0=62464
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC1=15360
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC2=0

CONFIG_VIDEO_SAMSUNG_MEMSIZE_FLITE0=10240
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FLITE1=10240
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

Using the inferno kernel. Antutu scores are lower than ever (like 4400), but I've basically learned to ignore it, because all I get on every rom and kernel are whack ass random results on Antutu.
On the plus side, nenamark2 bumped up from my previous max of 27.7 fps to 31.1. It is actually the first time I've seen a variation in the fps at all, from stock to other overclock kernels.
Sometimes backgrounded apps force close, but I haven't screwed with voltages yet, just running 1350/interactive so far.

I'm impressed. I've been running it for 40 minutes and it's my new favorite kernel. Running the 512mhz GPU version, I get 60FPS in n64oid. If I put it in powersave, the battery won't budge.
just flashed 512 version, can not wait to try this out for a day or two!!!
Checking out the 512 version. I wonder how much stress this causes the GPU? I imagine long sustained use of it at 512 could cause permanent damage to it? I have no idea, just wondering. Meh, who cares.... I get a new phone every 6 months.
Thanks morfic loved ya ever since the great old vibrant days and now look at you a million and a half codes later!

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

As we all know, our device has 768 MB of RAM, so I wonder why we just can use 624MB?
Is Samsung going to update JB 4.2.2 for us ? because our GB ROM uses 555 MB RAM, JB 4.1.2 uses 624 MB RAm ==> JB 4.2.2 uses 768 MB RAM, doesn't it?
There is only 624 Listed because the rest is used by our GPU I would guess. I don't think that we'll get 4.2.2 update. Because we are just a little mid range phone and not a flagship like the s4!

Modules and cpu make use of memory as well, but this is hidden from view to the system so it doesn't show. We do actually have the 768 MB tho
for 4.2.2, CM 10.1 and the custom roms built on it are all good, but i don't expect samsun to release 4.2.2 (or 4.3 even) anytime soon either

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.

+1 Android intentionally keeps commonly used code and apps in memory to save battery. Keeping apps in memory is more processor efficient than repeatedly dumping and loading them which increases load on the processor, and processor usage makes the difference in battery performance, not how much memory is being used.

I know Android does a good job managing RAM and that other task managers are worth using.
