Hello @ all,
as you might know we have only 343MB of RAM available to the user on our Arcs, but we have a total of 512MB RAM.
I did some research and found out that the most phones with 512MB RAM have 370-400MB or even more RAM out of the 512MB available to the user.
I know that there is something reserved for the system, but normally it's less.
But sometimes I'd really like to have a few MB more RAM available when I do multitasking or a lot of stuff is running.
So the question is if we can unlock more RAM for us and an even better user experience? And if yes, how to do it.
Regards,
Flo
May be a mix from a swap partition and the supercharger script is the right for you
The supercharge script optimize the memory management of android
Already have SuperCharger V6 installed.
Does a really great job and fixed the problem with LauncherPro Plus redrawing often.
But still I'd like to have more RAM available...
For example the X10 with 384MB has ~280MB available, so we should have ~410MB available on the Arc. And not just 60MB more...

No you can not unlock the RAM or ROM for further use, you however can optimize it by using external scripts and the reason for 343 megs being available is because around 150-170(approx) megs of RAM is being used by the graphics (GPU).... u did not account for that now did u... . Now maybe just maybe u can use a custom made kernel to squeeze some more juice out of the RAM...but no major RAM increase
Ah, okay.
But somehow it's possible.
Today I saw a review of a custom ROM on youtube for an Evo 3D...
And other phones with the same GPU have less memory reserved.
E.g. Desire HD, Desire Z
Strange that SE reserves that much

Your phone reserves memory for hardware, camera for example. It works the same way as reserved memory for integrated graphics on computers. We have HD recording in the arc now that has to come from somewhere, and just where would that place be?........the RAM. SE has tried very hard to squeeze in some very good features into the arc and that's why I guess they made a trade off with the RAM, and all these features require RAM and its not a luxury that SE has to reserve all that RAM but a necessity so we users can enjoy some great HD recording and amazing resolution.
One more thing even though the Desire HD and Xperia Arc do share the same processor (MSM8255 SnapDragon) the HTC Desire HD has 768 MB RAM and 1.5 GB of internal flash memory data storage and the Desire Z on the other hand uses a MSM7230 SnapDragon even though the GPU is the same the processors differ the MSM8255 is 1GHz and the MSM7230 is 800MHZ and in the overall equation of memory reserving other than the GPU the CPU has its part to play too and a very imp one...hope ur getting the idea and the GPU in the MSM8255 is a marked improvement over the GPU the 'Z' has. Now even though HD does have lesser memory reserved its not that big a difference. However on the arc, the camera is way much better than on the HD (camera-->RAM) so SE has used some more memory for better features.
I think everybody want to have more ram and more ram
but only thing that we can do is tweaking our system again and again.
I´am for example using the supercharger v6 option 4 and a swap partition and its great to see some improfment
I am looking for tweaks all the days but i am not so good in android so it need time
Ok, then.
If it has to be like that...
Just want to get the optimum out of my Arc.
Maybe a dev will come with a kernel that unlocks just a little bit more with keeping all the features

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?

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) ..
Hi guys
Quick question, i see that specs show the nexus has 1gb of ram.
But my ,"system apps," so it only has 632mb can any one explain?
Thanks
I think that some of the ram is reserved for the gpu. That's why you see less ram.
Just wanted to make sure
Still thou 400mb on gpu?

I was in looking at the Rezound and did a hard boot and checked available memory. It only had 250Mb of the 1 G available. The rest must have been taken by Android, Sense and whatever bloat Verizon is loading.
Have a quick look at my screen shot - ( if they work)
I beleive that is should be 1GB of Ram, i understand if some is used for system processes. but 400mb.... far to high i would think.
Any one care to explain?
Some is reserved for the OS to function at all times. Some of it is reserved for the GPU, and radio to use. It is done this way to ensure you have the maximum needed for these to run.

That makes sense.
Nothing is reserved for the O/S, that uses whatever is available. It's probably for the GPU, same as the Nexus S has 512MB, but only 384MB available due to the GPU being allocated 128MB.
my DhD has 621MB Ram. I wannet to know Is It possible to add ram to DHD and increase its RAM to 1024MB?
Anything is possible. But generally speaking, no.

I mean is there RAM Slots like Computer or not?
Not physically, Generally mobile devices like phones and tablets have SoC (system on chip). Everything is built into one chip, including CPU, GPU, RAM etc. It is possible, however it is not cost efficient nor is it a do-yourself job Other possibility is diverting some of the RAM used by the GPU to be used for some app. This is a kernel thing. For example: if You use a 3D heavy app => the kernel dedicates 256MB to the GPU and 512MB to the CPU; if You don't use the GPU much, the kernel would dedicate lets say 64MB to the GPU (more than enough for smooth internet, but not with videos browsing) and 704MB to the CPU and system. I know it is possible, but haven't seen anyone do it so far.
PS btw why the hell would You need more RAM than the DHD has? Currently there are no more than 5 devices with more RAM.
Thanks a lot
there is not a an important reason to extend my ram.but i thought it's good if is possible
HI
I want to increase my RAM because 1GB ram is not enough for some new games like Cypress Inheritance and as you know nitro HD has only 774MB available memory on stock ICS
I have been searched XDA and found these topics:
http://forum.xda-developers.com/showthread.php?t=1864732

but these methods are for Sony Ericsson XPERIA phones
I will be grateful if someone could provide a way to increase ram amount on our NitroHD

Seriously though, my assumption would be that the topics referenced aren't device specific. All you're really doing in either is setting up a swap space on the SD card that is used as if it is RAM.
can anyone confirm this method working on p930 and which one is better ?
I messed with various swap scripts and swapper configs back in my days on the G1, EVO 4G and even a little on the EVO 3D. It almost always ended up causing stability issues and laggy performance. It also wears out your SD card 10x faster than normal. Swap space just isn't anywhere near as fast as real RAM, no matter how you tweak it. It is only in very rare circumstances that you will notice any gains by using it.
Your best bet is to find the ROM that leaves as much free RAM as possible and run with it.
Hi all
My Xperia m dual become too slow sometime in such way that I can't even text properly and it become normal when I restart my phone
Why it is happening so
Is there any alternative solution except restarting??:banghead:

This is something to do with RAM. The longer you used your phone, the more RAM is consumed. Now don't blame Sony for bad RAM management, all Android kinda suffer the same... except higher ends have more RAM which helps those phone snappy.
IPhone on the other hand can literally outperform 2 or 3GB RAM Android smartphone, why? It's because Android chose to use a 'garbage collection' solution for memory management. Well it's not something bad if you have enough free RAM and is actually quite an efficient memory solution, but as the RAM usage increases, the performance drops dramatically and thus explains you're Xperia M to lag. IPhone uses another solution for memory management which is far more efficient as compared to Android's.
