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.

Full 512 mb available?

Does the froyo update make the full 512 mb ram available? I had heard earlier that only a part of it was available due to 2.1 limitations.

They were always available, ~300Mb for Programs and the rest for the system files... Why should that change?

I think what the OP meant was whether one had more memory for apps as ht tp:// developer.android.com/sdk/android-2.2-highlights.html claims that the 2.6.32 kernel upgrade would bring "HIGHMEM support for RAM >256MB".
At the moment, we do not have the full memory available in the Linux system:
Code:
$ adb shell
* daemon not running. starting it now *
* daemon started successfully *
$ free
total used free shared buffers
Mem: 333420 329988 3432 0 34724
Swap: 0 0 0
Total: 333420 329988 3432
I do not know whether that is related to the graphics hardware taking some of the memory, or to the kernel version:
Code:
$ uname -r
2.6.29
Edit: What do you mean by 'system files'? The OS is stored on mass storage, right? And Dalvik and friends should appear as userspace processes taking up regular memory.

You do understand that this does not compute, since there has always been more than 256MB available
Or has there?

I was wondering about the same thing, kernel 2.6.32.9 (JP3) also shows a little more than 300mb...

Hey, I'm just quoting from an official AOSP site

Mine shows 30 mb available under advanced task killer. What am I missing?

I've seen Desire have over 400MB of memory available for applications in a video with a some sort of task manager on..

Are you sure, max i got on my nexus one was 312MB in some rare cases, using it without closing apps at all, never got below 100MB... But my Galaxy's max is 170MB, is almost half what my nexus gave me, that kinda suck (don't know if it matter bu tit feels bad in my head )

Desire has 576MB memory.. N1 has 512MB

Maximum free RAM i got from my sgs is 210mb, easily achieved by using Astro's process manager and killing all non-essential services.

why t.f. do you guys always want to have lots of fre ram? please read a little about android memory management... free ram is wasted ram!

So? We all still want our phones to be as future proof as we hoped they would be when we bought them. And we want the extra RAM simply because it's supposed to be there.

As long as it doesn't go below that ~70mb when the phones actually start lagging
Might also want to take into consideration that the counterpart Desire used in this thread is also an android phone, sure too much free memory is wasted memory but too little usable memory = lag and if there isn't a lot to use in the first place then it won't take much for the phone to start lagging.
Some help in JG and onward firmwares but it's still quite funny that a simple user can make a fix to create a solution for the entire problem and Samsung hasn't either thought about this or taken it into consideration. (Mimocan is my hero <3)

Hey,
Actually you do not need that much RAM. Im running on JG5, which IMO is the most stable and usable firmware out there. Has been running the phone for 3 days straight without any ATK like apps, and has not experience any lags.
Another thing is that, IMHO ATKs slow down the system.

The current Samsung froyo builds do not support highmem. It is a kernel compile time config option. Samsung will hopefully enable it in later builds.
Highmem made a noticeable difference in performance on my nexus one.

Nonsense. You are not entitled to more free ram in any way.
Every os uses a part of the ram for the kernel code and its buffers.
In addition the advanced graphics will need memory for its texture storage and graphic representation.
A froyo kernel will not make a major difference.
The sg has 512 memory today and it is using it as it should...

lagging is actually not caused by to less free ram, in android there is no such. the used ram is caused by apps that you opened and then exited again. if you open a new app that needs more ram than aviailable (actually with a little gap of some mb) the system will close apps that are not used anymore and only kept in ram for faster opening. the lag comes from bad i/o speeds of the nand (internal memory) where apps data is stored. on i7500 there is 192mb of ram and it works ok with froyo (thanx to drakaz and gaosp team!) only thing is that every app you open forces the app you opened before to be kicked out of ram what makes switching between apps makes somewhat a pain.
also free memory and usable memory is apples and pears, useable is all memory that contains no actually running in foreground app or service. and free memory is the rest that contains absolutely no information and thus WASTED
edit: btw i7500 is running well with 20mb free ram.

I often have no more than 30 MBs free, and not running THAT many apps. What is strange is that sometimes there is 70-80 MB free, and I have not done anyting. What happens in the background is a mystery... Any suggestions?

[Q] Change graphics memory size

As I previously read, out of the 512 MB of our O2X's, some 128-140 MB are reserved for the Tegra chip-set, and the rest of 380 MB are available to Android and applications.
With Froyo, there were usually 180-200 MB of memory free after booting/killing all apps, and like 90-130 MB free after normal usage. I'm not sure, but if I remember correctly, in the running apps screen, the sum of the used/available memory summed up to about the previous stated 380 MB.
After applying the GB update, after booting/killing all apps there are only 140 MB free and about 60 MB after some usage. If I go to Manage Apps -> Running apps, the sum of the used and available memory is around 310-320.
My question is: why is there less memory available in GB? Has LG increased the graphics memory from 128 MB to 192 MB? If yes, is it possible to change this allocation? Or is there a ROM that uses less graphics memory?
Maybe GB reports available memory differently, but it's definitely noticeable that there's less RAM available. If switching from browser to another app, with Froyo the page loaded was kept in memory, however with GB the page always has to be reloaded even if the switch lasted like 20-30 seconds.
Edit: I'd like to use less graphics memory and have more RAM so my apps run faster.

No the Vram is the same. The phone still has 380 mb ram to use for the OS and apps. Also free ram is wasted ram since apps are not cached so they will not launch faster.

Not completely true. Android kills automatically unneeded processes, that's true, but sometimes it happens that an app remains in background and uses the 100% of the CPU, so i use the task killers to terminate it.

Try Super charger, very efficient and not as resources consuming than apps. Search the dedicated thread.
And I don't think there is a way to free graphical memory. I don't think it's software driven but physical...
The only thing that had been made is to free the reserved memory for OTA LG service, that leaves you some more memory, but only available in some roms.

Its possible to give the GPU less memory, different defs have done it (i.e benee). But as far as i know most of them removed that tweak since it was causing alot of bugs.
And yes, free ram are most likely wasted ram.

Hi kiljacken !
I remember that you've made some times ago a kernel with 64mb more of ram...
Also for the stock rom...
butI can't find it anymore...
Any help?

Thanks for the replies guys!
It seems like if possible, it's very complicated to change the video memory allocation, so I'll leave it like that.

hey all!
i have question like that! im working on electronic factory and have no problems with solder out and in BGA chips even the smallest ones! now the question! if i will solder out the ram chip and solder back in 1GB ram chip of the same tipe and company(i have acces to all the part available on the market)?

I'm very unsure. I am sure though, that both kernel and boot image changes would be needed to run with the added memory

i think it's impposible to change the graphic memory size, maybe RAM hack? if you want to free RAM just use supercharger, i already used that and my free ram about 117-130 MB

It's completely possible, it's something that's controlled by the kernel.

Such kernels already were in the spring which reduced video memory by 64 Mb

I suppose if LG's programmers were careful enough not to hard-code any values, the phone should detect the memory like a computer detects new RAM. However ROMs which target multiple devices with different RAM, like CM, shouldn't have such issues...

I would LOVE 1GB ram! What would such ram cost?

Guys, RAM amounts are hardcoded into the kernel, so a custom kernel would be needed to use the ram. IF it's even possible to use such amounts of RAM. There migth be limitations in the bootloader, which will cause problems, but kernel changes should be enough. If you try it on your device I would be glad to provide a kernel that supports that amount of RAM, but I don't think it's doable. AFAIK the RAM is tightly packed in the device with many other components. It might even be built into the SoC making it impossible to change. But IDK, feel free to try what you want, but remember it's your device that gets destroyed if something goes wrong.

Do it OP!

How RAM are allocated in Droid 3

I know there are 512MB RAM in Droid 3, in addition to 16G internal storage. However, I don't know what go to the RAM. Are the bloatware going to take part of it, or they are simply stored in the 16G internal storage? What about the OS?
Hope I can get some insights on this. Thanks.

i dont understand. your post sounds as if you think programs are installed on the RAM. they arent. RAM is random access memory, programs arent stored on here, they use RAM to run commands. The 16gb is what your programs will be installed to

Not all 512MB will show as total memory its around 370-380 I think that is because the graphics use some of the RAM. Some bloatware will preload into the RAM as well as some of your apps. But when RAM is needed for the program you are currently running lower priority apps preloaded will close. So even if you see bloatware running in the background it cannot take away RAM when you need it.
The 16GB is flash memory for installing programs, etc. Android is not like older versions of Windows Mobile where apps were installed directly to the RAM so the 16GB of memory and the 512MB of RAM are for two totally different tasks.

Thank you.
After I posted the question, I did some research on google. Basically your replies are pretty in line with what other say. The 512MB RAM is used when running program, and OS too. Motorola says there is a 1.5 secured storage space in the phone. I guess that is where the app are stored physically. When being run, the app will be loaded into RAM.
Yes, the sum of used RAM and free is less than 512MB. I guess the difference goes to the OS and graphics. That's what I learn after posting the question. If there is anything you think might help understand these terms, please share.
Thanks for all the feedbacks.

The ram is memory, the internal storage (both the 16gig and the secured partition/the 1.5 gig) are hard drives

[Q] HTC desire C storage problem!!

when i read at this page.... gsmarena.com/htc_desire_c-4759.php
at the storage it has "4GB include" but the device has 90MB rom and 940MB memory...
anyone please explain that
p/s this is my first post and i'm from vietnam, sorry for my bad english.
hello all you guy :good:

Welcome to XDA
I don't exactly know how it works but you only get around 1GB of space you could actually use!

Usuasable memory..
You are right. Both the websites and the box in which the phone is shipped shows the internal memory to be 4GB. But in reality this storage space is also used to store the phone's software. So the 4GB is actually partitioned into two parts, one storing the software and another part as the actual usable memory which can be used by the user. So you get a little less than 1GB of internal memory.. around 935mb or something. To know more.. go to HTC's website.

actually its split in three parts
1 part for the OS,sense,etc
2 0.94 gb for apps
3 ~90mb for storage (media,pictures etc)

apparently ICS+Sense 4.0+bloatware=3gb
it's like the galaxy s4, from 16gb you get ~10gb of user storage
imo this is just a marketing scheme something like internet speed ads. they say "internet speeds up to 150mbps" not 18mBps(even though it's the same thing) because ppl like big numbers ;the difference is you still have the same internet speed while with the phone the 4gb mem is a lie ....unless you format the whole internal memory and use the phone as a throwing weapon....
