I just installed the JM2 firmware, and was surprised to see a new Samsung widget task manager (which is actually really good! =O).
However, once I opened the task manager and went to the 'Summary' tab, the RAM information lists it out of 326mb. For example, at the moment it's showing 258mb out of 326mb used...
Is there some separate ram locked away? As I thought the Galaxy S had 512mb...
So anyone know what the deal is with the 326mb listed instead of 512mb?
Need Froyo to address 512mb.
Next time, please use the search button. It's startin to be a pain to write this over and over again (and not just me.)
The device was taken apart to bits countless times, it does contain 512MB RAM.
Why can't you see it all? the software doesn't show it. YET. Remember that the original JF3 firmware only showd 256.

Ah, apologies.
So does that mean currently the Galaxy S isn't actually using all its RAM due to the firmware not allowing it? Kind of strange, didn't know there was anything preventing the use of it at all since the Desire and Nexus One were happy enough with 512mb on Eclair.
Two queries though in relation to Pikas post -
I believe that this issue was uncovered over on GSM Arena. I think Samsung at the time assured everybody that the odd RAM results was just a firmware bug that would be resolved on release products.
So we have a release product where there are still problems with the memory and GPS.
Secondly, I thought it was the kernel that limits the memory to 256 through a Himem flag? Why is then that people are now seeing 326 and not 256? Is it a half way fix? Has the kernel changed?
Your question is not dumb at all.
No phone depends on Froyo to use more than 256mb of RAM.
Even if our phone have 512MB of Ram, we probably won't have so much available.
Many phone always have some ram used by the radio hardware.
I don't know if Samsung will be able to reduce radio (GSM, 3G etc) memory usage.
326MB is maybe the maximum we will get.
I bet we'll see 386-400~ after froyo.
The system is more memory efficient.
If it says 512 it should display 512.
The problem is that when you open the task manager it displays 258/386. I thought it was using the remaining RAM for VIDEO. If its not, then we should see a 512 no matter how much the OS consume. It can even be 500/512 but it should say 512.
I hope Samsung fixes this soon as they sold me a phone with no working LEDs and less RAM??!!

That's not the prob. In Samsung's task manager it's showing the entire phone has a MAXIMUM of 326mb RAM, and obviously much less free.
On Advanced Task Killer I usually have between 70-140mb free, not that much different from my old Hero.
As has been pointed out this may be due to the Galaxy S's use of 2 different types of RAM, with 128mb OneRAM. I can only assume this is dedicated to video.
This would then make sense for the 326mb RAM listed in most applications, with the extra 60mb or so locked away for Android (326mb + 128mb + Android reserved = 512mb).
Still kind of weird how Samsung has made the phone...I was trying my friend's new desire and it listed in Advanced Task Killer as usually having about 240mb free while mine had 100mb free.
I posted originally at [Q] Amount of RAM? under Galaxy S I9000 Q&A , but I guess its relevant to this post as well.
There is new information to indicate that perhaps Galaxy S doesn't have 512MB of RAM after all. Click on the above link .
Samsung Open-Source may hold the key..
Samsung have released the kernel source code for the GT-I9000, and it helps a little bit with trying to decipher what's going on.
From what I can tell, based on specs and previous posts, the SGS has 384MB of -normal- RAM, and 128MB of "OneDRAM".
OneDRAM is a dual-port memory, which means that multiple chips can be connected to it, and using it at the same time. For example, the phone main CPU and a graphics co-processor could both be sharing this memory and using it to communicate with each other. For more details on what OneDRAM is, I recommend trying google.
From what I can tell, the OneDRAM is used for a few things such as video memory, shared communication buffers with the phone hardware etc.
There are a few places that hint at where this memory may be going, the first of which is the kernel configuration:
CONFIG_ANDROID_PMEM_MEMSIZE_PMEM = 16384
CONFIG_ANDROID_PMEM_MEMSIZE_PMEM_GPU1=8192
CONFIG_ANDROID_PMEM_MEMSIZE_PMEM_ADSP=1800
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC0=12288
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC1=1024
CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMC2=12288
CONFIG_VIDEO_SAMSUNG_MEMSIZE_MFC0=32768
CONFIG_VIDEO_SAMSUNG_MEMSIZE_MFC1=32768
CONFIG_VIDEO_SAMSUNG_MEMSIZE_TEXSTREAM=10240
=> These parameters describe approx 128MB of space that is being reserved at boot time for the GPU, DSP, Camera(s), and communicating with the phone hardware.
I'm not sure yet whether all of that memory comes out of OneDRAM or not (I haven't spent too long looking into it, and I'm not really much of a kernel guy).. however, it seems that linux-2.6.29/arch/arm/plat-s5pc11x/bootmem.c might offer a few more hints as to where it goes, if anybody's keen to look.
I seem to have gotten a little bit off-track, but basically, it seems that yes, the phone does have 512MB of RAM. It's just that some of it appears to be "locked away" for special use before anything else can get at it. This is probably because the coprocessor(s?) require blocks of contiguous physical memory, and achieving that would not be able to be guaranteed if standard memory allocation techniques were used. Maybe someone with more of a clue than I can help fill in some more of the blanks with the above...
Regardless, I don't think that the apparent discrepancy is anything to worry about. The SGS is an awesome phone, and that will remain the case whatever the amount of RAM it tells you is "free" (well, within reason I guess). Go and and enjoy it for what it is

False.
With Froyo you'll be getting a total RAM of 304Mb.
You do know that basing a statement from what you see in pre-alpha/alpha firmwares is a really bad idea, right?

But, has anyone ACTUALLY confirmed we don't have 512MB of physical ram.. I've seen lots of guessing, but I haven't actually seen any proof yet. So has someone confirmed it by actually checking the hardware..

Has anyone actually confirmed that we DO have 512MB ?? I am yet to see any firmware reaching over 384MB, and all the evidence out there suggest otherwise . Samsung says it has 512MB RAM, but they never said all of that memory is available for Applications. So it could very well be 384MB regular RAM (available for Apps and system) while rest is reserved for specialized hardware. Technically that is still 512MB *RAM*, given that manufacturers have a tendency to overstate numbers and specs, I'm not going to take Samsung's word for it...
I hope at least some of that is being used by the OS.

Obviously, I'd prefer 512MB plus this 128 locked away separate, but this sounds like an elegant solution if correct. Also, it goes a long way to explain how the SGS can be pretty snappy in areas like gaming while maybe keeping other vital parts open and smooth like the 3G radio.
*EDIT* I'm reading now that new pressers have released more official information on newer Galaxy S models, still I've googled for them and even gone to Samsung site, still haven't viewed anything with my own eyes from Samsung.
Well, that's my point.. The problem I'm seeing is that I've seen quotes for OneNand and OneDRAM in many places, but it is based on random diagrams for other phones, or rumors... I'm simply interested in knowing the truth, but am growing increasingly concerned by the growing number of claims about this phone, which are being repeated, but after some research, many I've found seem to be based on information which isn't actually proof (and often, seems to be based on stuff such as "I heard the SGS has...".
As I said, SEMC was running around claiming it was OneNand (which isn't even RAM), using claims which I've never seen proven. OneDRAM seems more likely, and it would mean we basically have 512MB of RAM (oneDRAM seems as though it would be usable for normal RAM too), but I'd still like to know for sure..

Hopefully you are right, any source where i can see the official statement about this issue?
From another thread:
Sigh. No. No ROM ever will. This is because the radio firmware reserves a lump of RAM all to itself so that you can... you know... make and receive calls.
Can you imagine how annoyed you would be if you missed calls or SMSes just because you'd used up all the available memory?

N1 only saw ~200MB of RAM because a bug in Linux kernel. With the bug corrected you see 512MB of TOTAL RAM.
And yes, N1 owners complained about this. The difference is that there was a lot less fanboys defending Google or HTC about this matter.
Even the Tab has 444MB

I'm 99% sure that's wrong. It wasn't a bug, it just didn't support larger amounts which was because of the way ARM was designed apparently. Linux was designed that way, and needed to be updated.
This is a totally different situation, and not sure why billboa is claiming that samsung now markets the SGS as 384mb of ram either. I have seen NO evidence of that, and if that's true, please show proof the SGS is being marketed as 384mb.
I agree that we do need more spare RAM to be available (especially in the froyo leaks, which may be betas anyway) and the currently-reserved RAM to be allocated dynamically when needed, so there is more ram available at other times. RAM allocation is cheap afterall.

The galaxy s actual does have 512mb of RAM inside it. Out of that 512mb, 128mb is used by the gpu or something involving the hardware(I don't really know where so not going to pretend I do). Then out of the remaining 384mb some is used by the system. I say some cos different kernels use a different amount.
Like on damiangtos 2.2 kernel there was 360mb of ram free at one point.
How much RAM does the Captivate really have? Reason I ask is my friend's Droid Incredible constantly has about 270-280MB free, even when he was on 2.1. My Captivate has about 150MB free after doing a task kill. I thought these were supposed to have 512MB of RAM, but this post says that the new Samsung Continuum has the same 336MB as the Samsung Fascinate. So, who knows for sure, with rock solid concrete proof that these phones have 512MB??
"The device looks to have the exact same 1 GHz Hummingbird processor, 336 MB of RAM, and Super AMOLED display as the already released Fascinate (we assume the camera and battery are going to be the same as well). "

Ok, so it says 512MB of RAM. Well why cant we access the whole 512MB?? People were just saying "well 2.1 cant access all of it", which was garbage. My friend's droid incredible on 2.1 accessed all 512MB of its RAM. Now that Froyo is out for Captivate, its own built in task manager says it only has 304MB of RAM.
So, how am I trying hard? And what am I trying hard to do? I'm just wanting to know a solid answer. Where the EFF is the rest of the 512MB of RAM that these phones supposedly have? I regret buying a samjunk phone every day. Should have never wasted a dime on Samjunk.
Take it back; sell it; get rid of it then.
No one forced you to buy it or keep it.
The spec sheet says it has 512MB of RAM - some speculate that some of it used as video memory; other mentions say there is a RAM disk taking up space.
I have many apps open and running and i have not had a problem with running out of memory - so I am not to worried about what is available.
The initramfs uses a few MB - not much, single digits. The stock kernels also include ramdisk support and set up 8 8KiB ramdisks iirc. None of this accounts for the amount "missing", but space reserved for two or three screen-sized buffers, and for texture memory, etc might explain it. I have no idea where people get this idea that eclair kernels can't support 512MB.

Thank you. Educated answer. I know it has a 512MB chip in it, I dont think anybody is disputing that. What I was wanting to know or figure out is where is the missing RAM? From 512 to 304 is a good bit missing. So out of the 304MB the OS takes up about 160-180, that leaves us with about 120-140ish for program memory. To me, it doesnt make much sense to put 512 in a phone then hide almost half of it from programs. I demo'ed a Moto Droid last November for a month and it came with 256MB and after doing a task kill it would have about the same as these Galaxy S phones do. My guess is that some of the system ram is being reserved for video ram, or other's have speculated that there is a ram disk in there. Maybe a combination of both, vram and ram disk. I think its wrong for samsung to advertise "512MB RAM" to compete with the likes of N1, Droid incredible, EVO 4G, all of which have a true 512MB, but our phones have a large portion of that 512, thats not accessible. It'd be a lot more honest if they advertised 304MB.
Actually 128 MB of the RAM is dedicated to the gpu. I don't know specifics but I'm guess this is part of the reason why the galaxy blows everything else away in gaming. It is a little dissapointing but whatever. I feel the same way bout it as everyone else.

Anybody checked how does it look in i9000 or other GalaxyS-family phones?
Tear-downs have revealed that the phone does have 3 different chips that add up to 512 mb. Unfortunately a sizable portion is reserved for an unknown reason.
Has anybody been able to get a solid answer about where the missing 208MB of RAM is? Is it a ramdisk, is it video ram, is it a little of both? Who knows? Samsung knows but they wont admit that it doesnt have 512MB.
I've emailed samsung customer service several times explaining that my phone system information says 304MB RAM. They just reply, "Captivate does indeed have 512MB of RAM. Thank you for your inquiry.... blah blah blah."
It does have a 512MB chip in it, but what's it being used for, is what I'd like to know. N1 doesnt have this problem. Droid incredible doesnt have this problem. Droid X doesnt, etc. The G2 does, its advertised as 512MB but when you do system info on it, it has 380MB.

it seems like i'm still showing ~300MB total RAM (90MB free) with the leaked Captivate Froyo rom. i'm using an app called "Android System Info". should i not be seeing closer to the 512MB mark?
Same around 300....But I don't think I will be multitasking to the extent where I will need 500MB. I close BG apps routinely I am not using.......to save data.
I usually keep all Email syncing on, Latitude and sync FB as needed.
The amount of ram its the same in froyo. I tried android system info and same results. Try using the built in task manager in your apps. I have a feeling its more accurate than asi. I'm showing much better ram usage with built in task manager. 190-230 free on froyo opposed to 50-120 free with 2.1.
Oh yeah you can just push and hold your home button and then hit task manager on the multi tasker.

304 total. :-/
ATT might have the RAM locked at a lower number so we do not meet the requirements for Android 3.0. That way when everyone starts pissing and moaning when they don't release it, they can say sorry...
Or they saved some money and put in less RAM in the U.S. models. I don't have the box or spec sheet in front of me but I do not recall ATT ever saying the Captivate has 512 MB RAM. Everyone just assumed it because the Galaxy S and other variants do.
I never had an Android device before, does it show physical RAM or addressable? What does the Intl. Galaxy S show? If it is the same as us then I guess we can't complain as much.
Perhaps the badass GPU in our phones uses shared RAM? Or maybe the address space is limited for some reason.

Samsung says it has 512 mb

Eclair is incapable of seeing more than 304 MB, and the leaked Froyo is still just a leak and not an official release. Just sit back and relax. If the official Froyo does not utilize all 512, then we'll have a reason to complain...
I've read somewhere around here that we will never see all 512mb of ram, because 128mb of that ram is dedicated to video... no sure how true it all is though.. my 2 cents
The phone only has 304MB available to the OS as RAM. The rest is reserved for some other function such as ramdisk or vram, or maybe both. I've emailed samsung numerous times but they wont even admit that. They just reply simply, "The Captivate does indeed have 512MB of RAM.... blah blah blah, etc etc etc." Getting a straight answer out of Samsung is like drinking soup with a corkscrew, just not possible. Its like trying to find out if JH7 had a GPS fix or not. They wont say definitively whether it did or didnt.
on the specs, it says GS1 has 512mb of RAM. I know android OS takes space phone it self blah blah so we only get to use 3xx mb of RAM. but then usually half (if not more) of the 3xx mb of RAM is already filled!
before, (back in eclair & froyo days) android 2.3 will allow us to utilize ALL 512mb but ****, now even more RAM is in use..
also
someone told me Nexus S who has exact same specs as GS, can use ALL 512mb...
so is there a way to use all 512mb of RAM? or at least more than 329mb?

You do use all the RAM, Android users shouldn't be worried about RAM as it is good to be used... Now Samsung's excuse for updating the GS1 to ICS is bull. but the reason you get 329 MB of RAM is because that 183 MB of RAM is for the system and cannot be given to the user. There are some kernels that offer like 344 MB of RAM(for Froyo), but that is it. No more, no less. Can't change it! Sorry bud.
Edit- we always are utilizing all 512 MB of RAM always. And when half of it is filled, that is always going to be there if the phone is turned on as some none system apps and system apps cannot be closed and are needed for the device to function.
I just recently got myself a Samsung Infuse, really like the phone. One thing that really bugs me is that it appears to be the same as my captivate in terms of RAM and ROM space, yet on my Infuse i get access to 452MB RAM yet on my captivate as stated we only get access to 329MB or 344MB.
Why such the huge difference?
