How much RAM is free on your galaxy s? No himem kernal support

My friend just got his phone from unlocked mobiles, i am still waiting for mine from Handtec... argh... but i just got him to check how much free memory he had from looking at advanced task killer and he only had 37MB free!!? Got him to kill everything and he only got about 130MB free in total.
Can other people check theirs to see, because its looking like the same problem that happened with the nexus one where only 256MB of the 512MB RAM was available to use, until they upgrade it to Froyo 2.2 or change the kernal to allow for Hi Mem support.
rubbish if they havent sorted this!

anyone?

ya.. its the same because of the limitation in 2.6.29 kernel not the phone. More reason to bug Samsung to upgrade to froyo or root the device

Yeah i don't think they've fixed it, ,my phone only reports about over 100 meg free.
where do you go to see memory available?

122m Avail. memory using adv task killer.

bugger, i thought they would have at least sorted out the kernal to support himem. if XDA developers can do it for android 2.1 then why cant samsung! very lame and annoying as I have seen my friends phone slow down quite a few times now.

I flashed froyo JPD + voodoo lagfix and my RAM manger shows
191 / 304 MB.
I choosed level 1 and 2 and clean memory, now it is using 144 MB.
I guess it is supposed to show 512 MB.

If I kill everything, 142M free (stock JVK). I used to be able to get ~170M free with JPY...
I'm of the, sometimes controversial, opinion that unused RAM is wasted RAM though and don't really care how much is free - as long there's no lag!

I have same opinion. We will never see 512mb ram available, as someones may think..we HAVE 512mb ram, but due technical issues, it won't be all usable for us..and as a linux based system, it's good to have mem full as possible. Generally speaking...
There is many topics about ram in xda..with lots of information..

As far as i can remember, we don't see the whole 512 mb RAM (or at least 400+) because of PowerVR GPU, which reserves a lot of ram for itself.

[Q] How much RAM?

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). "

From what I have read. The cappy has 512 but can't use all of it till froyo. 2.1 can't see all 512.

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.

I just spoke to samsung level 5, its top secret and they will never disclose the answer! Muahahaha

As much as I would also like to know where the rest of the ram goes, it doesn't matter so much when we dominate the quadrant scores with a small tweak

Could u please elaborate this? Or atleast could u pls link to that site?

how much ram do we really have?

i thought the cappy had 512 mb of ram... why do all the roms have like 341? im confused >.< either i looked at 3 faulty spec sheets for the captivate or we arent utilizing the full ram potential for the captivate. would someone explain the truth on this matter to a captivate noob like me?

i could be wrong but i believe the 341 is available to use ram, while the rest is being used by the phone to function.

that would make sense, but that makes the specs misleading... i traded my HD2 for a cappy because the spec sheet said 512mb of ram and the HD2 only has 411 available to the OS when running android from nand because the rest is dedicated to winmo only (which sucks massively), and i wanted more ram lol, guess i should have looked harder into things, but regardless the captivate is "better" in very many areas, but RAM is literally my deciding factor for so many things lately (like t-mobile with the sensation or sprint with the evo 3d, i would say evo 3d because it has 256mb or so more ram)

This question has been asked and answered several times....
the phone does have 512mb of ram. Like the person above me said the phones os and graphics take up a portion of the ram. All computers and smart phones work the same way.
As a side note android handles ram very well. You don't need to manage it at all by freeing it up. free ram is wasted ram as the os will have to load it back up anyways

i know this very well, free ram can be considered wasted ram, unless you need 200mb or so free for a tegra class game, but i think android handles ram awesomely to an extent but can be improved by implementing autokiller memory optimizer in a knowledgable and appropriate way that doesnt hurt optimizations android already has in place, zipaligning, increasing the dalvik heap size, etc... can all be done, im not asking about how android handles ram or anything, and im sorry i didnt know the question had been asked several times i am brand new to the captivate today, literally, and was doing not but seeking information i didnt understand or know, thank you for the explaination though i appreciate it, and im glad to know that my new captivate will utilize the left over 171mb of ram for something unlike my HD2 that couldnt access the last 100mb because it was designated to winmo only. i had an idea that was the case and i was just clarifying to myself because i kept reading rom changelogs stating "enabled more ram now 341mb available" or something along the lines of that and thought to myself "there should be more available already" lol

I honestly think 341MB is enough.

341 MB is alot. But something is taking all that up too. On a fresh boot, half of it is used, and I have 140~170 MB. Its even worse on GB. Most ive gotten is 100 MB free.
So if the half of the 341 plus the mysterious 171 MB that is nowhere to be found, I dont get whats using the other 171 that is not part of the 341. Lol confusing

Same happens to me. Who knows, lol

[Q] Can I increase the physical RAM size?

Dear all,
I am curious if I can purchase a larger RAM module and replace the one in my SGS resulting in more RAM space available to applications?
My SGS is running fast but I have a lot of applications installed which utilize RAM in background. As everyone know although SGS claim to have 512MB memory, the actual memory available for user application is around 3xx MB only. I am woundering if upgrade of physical RAM is feasible.
Thanks!

I'd highly doubt that it would be possible. Maybe some high skilled person could make the swap (it probably wouldn't be easy to find one..), but no-one knows if it would have even theoretical chances to work. And yes SGS has 512mb of ram..but os and apps just take their part of it in any situation.

LED notification issue and Less RAM

Hi All,
Bought a new Xperia SP! Love it but have 2 issues:\
1) The LED notification for missed calls not working (rest is working)
2) The ram is showing as 786 MB only!

1) +1 (a bug. I believe if you disable STAMINA power mode it works, but haven't tried it)

Any one know how to free up more RAM without root. My free RAM is very low and I think thats the reason why Firefox crashes randomly.
And where is the rest of my 1GB RAM?

Actually, I'd also like to know what's using the remaining 200MB or so of the 1GB RAM. Is it the system? Surely the system is already included in the used RAM indicator? Or maybe it's for the graphics?
I do find it annoying that with its advertised 1GB RAM the SP all too easily appears to run out of memory. Loading up complex pages in Opera set for "desktop" user agent frequently causes background apps to be kicked out. Sometimes even Opera appears to be booted out for using too much RAM! This shouldn't happen on a modern 1GB RAM device, when there's still around 200MB RAM free, and a further 200+MB "missing". It's a bit of a joke really... Now I can begin to understand why the latest hardware has 2GB.

Seems 200MB is reserved for the system. And also XBMC seems to use alot of cache memory. Removed XBMC and turned of alot of Sony apps and now I have a decent amount of RAM left.

So, I think everyone still dunno what the "1GB" RAM mean...
usually in android phone, the 1GB RAM was not exactly 1GB, normal scaling is 7XXMB user and system access RAM + 2XX MB system hardware reserve RAM (usually ur GPU - it's like the old Intel GMA)
Then 7XXMB user and system access RAM is further separate to user access RAM and system process reserve RAM (just see how's they scaling)
And it same as other market advertise 2GB, 512MB, etc Android Phone, even S4's user and system access RAM also approx 1.8GB instead of "2GB"
U all are still haven see how's Samsung stock ROM make their RAM usage always in busy usage (If someone got use S Advance with updated JB Stock ROM then u should know)
If got time u all should read this:

What's xbmc?
Sent from my C5303 using Tapatalk 4 Beta

XBMC is Xbox Media Center. It was first developed for the original Xbox.
Now its available for all platforms like Android, , Windows, Linux even Rasperry Pi. Its a complete media center solution with any function you can think of.
Google it, its really interesting. It has full media functionality with its own UI. You can watch movies, stream tv shows through internet, listen to music, run software, its almost a stand alone operating system.
Under Android you can even use your phone as a remote/ keyboard to navigate through XBMC while having it installed on an Android tv stick.

i got the xpeia sp recently and im a bit sad about the multitasking of a mid range android phone and i want to find a solution, i have another really cheap chinese quad core phone and the ram is 1gb too, in the info at antutu benchmark it says 971 mb whereas the sp says 766! im sure there is a solution out there to make the most of the ram and get better multitasking, can anyone with cyanogenmod rom tell us their ram value please?

also some of it s used by the Adreno 320 GPU.

both phones when empty from bloatware, the xperia sp free ram is 260mb and the chinese phone is 422 mb, why?!!!! i want the value to change at antutu benchmark device info to 971 mb instead of 766 mb is there a way??

We have 1 GB of RAM. Aprox 200/250 mb is for system. For:
- Camera; filming does not work without enough RAM
- GPU; If you have a PC and you game a lot you know what i mean
Also for being able to connect, and have the system running smooth there is RAM needed.
About your LED issue:
Stamina mode enabled? If yes disable it or download illumination bar pro
It has been stated many times by sony that stanima mode disables the LED to save battery

The Chinese "Super" phone you refer to more than likely has no manufacturer skin like Touchwiz etc, and zero bloatware thats why it has more free ram.
with a MTK Cortex A7 processor, as for performance goes it cannot compare to the Xperia SP.
you've already been told some of the Ram is reserved for the GPU/Imaging camera system etc.
tweaking androids internal Minfree values can with multi-tasking.
