Hello everyone, I found that my Desire Z has only 371MB RAM. However, my previous Nexus One had 460MB RAM even in the app or "About phone".
Where is the remaining RAM go?
Sorry for my bad English.
May anyone answer my plz?
This is probably only true for windoze machines... but some of it may be reserved for the os and gpu.
Sent from my T-Mobile G2 running Cyanogenmod.
I see the same on my USA G2. 371mb. fwiw I only ever have like 140mb being used at any given idle time so its not a big deal. I'd be more worried about this if I was maxing out my RAM.
i have started my own and read every topic about why we could not see all the ram as user available (329 instead of 512) .. first i compared galaxy s with tab but it turned out tab has 640 Mb of real memory in total.. but i also have seen it was possible to add more memory about 40 Mb to the user available ram .. and i also learned there is also a part which is not used and called "blackhole" approximitely another 40 Mb..
so i believe it is possible to make some adjustments to improve the weakest (according to me) part of our galaxy s.. would some devs please mind trying this for us and share it?
We don't need the RAM (yet)
There are a lot of developers who try to get more out of our SGS's. For instance Juwe/ GingerReal increases the RAM to around 340MB.
Appearently Google thinks we don't need the full potential RAM and that's why they made it with a default of 300-330MB. Still still most developers agree on XDA that we should be able to acces the other 160MB because it doesn't do anything.
Until then we'll just have to wait.
even 340 Mb instead of 329 makes a difference .. i cant think what would happen with 380 or 400 or maybe even more..
because as far as i understood from what i have read; 128 memory is reserved for some drivers and capturing video is taking most of it.. i am taking a video maybe once in 2 monts.. but i am using my widgets, apps, playing my games everyday.. so if was asked to choose i would love to have that memory reserved for video taking..
edit:typo
First of all, the amount of RAM is NOT related to the ROM....
The kernel makes the difference...
In general the max amount of RAM in Gingerbread is 340MB, cuz if we go over the phone will become unstable and we'll break some functions like 720p recording....
In Froyo we used to reach max of 350MB without issues
just curiosity;
galaxy s2 and galaxy s has the same rams with different amounts.. what would happen if we soldered the 1gb ram to galaxy s? would it recognize it without any software tuning? or would we just kill the phone completely? or would still see 329 ?

so is it possible to disable video recording completely and having lots of more Mb?

Do you want to instert 1GB ram into our SGS? I dunno sincerely what will happen.....

Probably yes, i am not a kernel expert, i am only a rom cooker/recognised developer, so my knowledge on kernels is very basic....
Maybe you'd better directly ask to a kernel dev like hardcore, nikademus, chainfire....

i would really want that but i am sure its not as easy as soldering the gps antenna.. i have read about a HTC device getting a memory upgrade to 128Mb from 64 in xda forum.. so technically there is no impossible but i wonder what else need to be done after soldering the ram? software adjustments (kernel maybe?), or any more hardware changes ?

thanks for tip, i will ask them..
i am really feeling bad about this ram issue.. every web page is showing nexus, galaxy s, galaxy tab have 512 Mb of ram.. but the memory dedicated for users is far less than the other 2 phones in galaxy s ... so it bothers me.. is there anyone who returns their phones to samsung and gets the money back?
first i believed somehow it was possible to use most of the ram with some software adjustement but then i realised even quadrant shows the total amount of ram memory is only 384 mb (and there is a part which is not used at all) ..
well... i just came from Evo4G and im very new with samsung with android..
i didn't bother to check when i first got the phone but right after my rooting process and installation of Miui 1.9.2, i installed perfect system monitor app and put the widget on my main screen and it showed 345mb of ram and only had 49mb free ram..
i was like WTF!! but is this normal? i thought NS4G came with 512mb?
is there a fix?
i do believe the Nexus comes with 512 ram. sounds like theres some setting displaying wrongly
It does have 512 RAM
I've read about this very issue on other forums before.
Some people speculated that it limited the RAM on purpose because the OS doesn't need it all and later versions of the OS would need it.
But ultimately I saw someone post that said that the GPU requires a certain amount of RAM, and so it is almost like partitioned and is unavailable for the rest of the system.
Development? Nope. Thread closed.
And for the record, Irrowley is correct. It is allocated to the SGX 540.

Hello, I have the latest stable build of CyanogenMod 10 on my Samsung Galaxy S3 i747 (AT&T) and its specs say it has 2GB of ram, but my phone is saying it only has 1590 MB of ram. Its a weird number so I was just wondering, is it the amount of ram available after what it needs to use to run the OS? Its not really a big deal and I love CM10 but its just something I've been wondering about and can't find anything about it.
Specs:
Galaxy S3 i747
Android 4.2.1
CM10 10.1-20130121
Kernel 3.0.57-cyanogenmod-gb1ea79a
Thanks in advance!

That number is about right. Even under the stock ROM if you look at Running apps (services) the total is around 1500 to 1600 MB. If I remember correctly the rest is reserved for the OS and other things.

Ahh, okay thanks. The phone still runs lightening fast so its all good. Cm10 is still a little buggy but the pros definitely out weigh the few cons.
I was told a good portion of that missing memory is reserved for video memory.

Whats your favorite Firmware???
I am asking because there are so many Jelly Bean Firmwares out there and I wanted to know which one is the best for you.
And I think it´s good for users who don´t know which Firmware they should flash.
MG2 is the smoothest one with 624 MB ram, but drains battery fast...

I updated to MF1 via kies and got 482 MB. which firmware should i install to get 624mb ram. Device is from UK
Do i need 3 files or one file?
Flash mb4 for 624 RAM with pit then flash mf1 mg2 etc.

The russian MG2 (SER) will give you 624 MB, you can flash it directly no matter what rom do you have currently on the device.
You can find a torrent link on my signature or hotfile link on sammobile.
It doesn't matter if it's 624 or 428 ram. Your device has 768 mb ram, it's just allocated differently and thus you have 624 or 428 ram. I'm running nordic MG2 with 428 mb ram, and it is smooth, there are no hangs, it's almost like GB. So don't base JB firmware on how much ram your task manager shows!.
Guys, i having BUT-XXMC8 Firmware and it's not bad
is MG2 better than MC8 ??
if yes sure i'll flash it over MC8.. i think no matter with this way right?

it has 768 mb ram, correct. but only 482 is usable, cant you understand? you might not have many apps running and using ram, but other people may use more apps than you. based on what you said, you mean a pc with 8 gb ram, and it so happens you can only use 1 gb(no, but example) you mean you will say"oh this pc has 8 gb of ram, its just allocated differently. dont judge the pc based on ram." I will have to tell you thats totally wrong. For gaming, customization, multitasking... ram does matter. So instead, just tell them how to get 624 mb ram and dont encourage them on the wrong things. And for those who needs 624 mb ram, first flash XXMB4 then your desired firmware(JB)

I downloaded MG2 from your torrent link and installed it. I got 624MB ram . It's faster than MF1.
On samfirimware there are 2 MG2 firmwares.Poland and Hungary.Which one is better?

You can't compare PC with smartphone with Android. First if you go to properties in my computer in windows you can see that you have RAM and how much ram is usable. Second RAM management is different in Android and Windows. Google said that 1 GB RAM is minimum for JB and we have 768. You CAN'T GET MUCH OF MULTITASKING WITH THAT MUCH RAM!!!. I had 624 mb ram with repartition, and the RAM gauge was always filled, I constantly had 500 ish ram, and the same thing is with 428 ram, I always have 400 ish ram. Gaming performance was worse on any firmware with 624 ram, mc8, me7, mf1 but with 428 ram on MG2 it's much better. My point is that mg2 build is optimized good enough with 428 ram, and if you repartition yout system you will have same effect, maybe even worse with 624 mb. I guarantee that with 624 ram you won't get much of multitasking and you will repartition your system, which is always a bad choice, so it's futile to search for multitasking in jb on our device.
1gb is minimum? But then again, you can only use 0.98gb. "Google said you need 1gb of ram" huh? So having 0.98gb cant multitask either? Lastly, this is a thread meant for discussion, not arguing.

Minimum 1GB of physical memory, not usable memory. My point is not to argue, but I don't want people to flash 100 builds just to get "624 mb RAM" when it's perfectly fine with 428 mb, and there is not difference in performance, if anything else 624 mb is worse. This phone is tailored suited for GB, I think we will never get official Samsung update with better performance than GB, in best case we will get same performance as GB. And that's the case with all devices without physical 1 GB of RAM. I am using official MG2 now, updated with kies and it runs really smooth, games are OK and I don't have any freezes or lag so it is definitely an improvement. There will me more builds, and about 2 months ago when I talked with Samsung Norway they told me that JB will arrive in 3/4 quarter of the year, and I think that final builds will come then, but MG2 build for now is just fine for me.
Sorry for misunderstanding. And i agree it was made for GB

If a phone with single core cpu and 512 MB ram can run JB don't try to explain that 768 MB RAM and a dualcore processor is not good enough...
Just flash the russian MG2 you will have 624 MB usable ram and almost every time there is approx. 100 MB free, the rom is extremely smooth, there is only a little lag which is caused by poor drivers/kernel, just like the huge battery drain.
Soo... that "made for GB" excuse is probably good enough for samsung trying to fool us, but it's not true...
I can remember when I bought my phone GB was almost in the same state (little lags, battery drain, slowdown) and after the 2012Q4 performance updates GB became well optimized.

No, with the Hungarian XXMG2 version you'll have 482 MB usable ram, with the Russian XXMG2 this value is 624 MB.
I don't know anything about the polish fw but I recommend to flash the Russian JB.

I didn't say it can't run, it can run JB, I'm running JB now on my phone. The question is not can it run but how it runs it. I agree that performance will be better with next updates and that was my point, but what I've said is that don't expect to run 4-5 applications in once or to have fantastic multitasking. About a battery, there is slight decline over GB but not so much. I've noticed the biggest drain is with wi-fi on, with camera app and of course screen usage. Project butter uses a lot of battery for now I think, because to use video sync and to run at 60 fps Project Butter needs graphical intensity which was not presented in GB. And one more thing, did anybody noticed that camera quality is lower than on GB? For me it seems like it. I think in September/November we will get usable enough build and Samsung will end support for this model I think.
question
what are the differences between the firmwares? and does the different version affect the battery life of the phone? thanks

It's up to you. If you value more battery life and performance, stay on GB. If you want Nature UX, smooth UI and new features with lower battery life and less performance in games, than go for JB. If you want to move to JB then I suggest to flash nordic MG2 directly from GB via Odin.
