I remember there was a method to partition part of the external sd card and use it as extra RAM.
Can anyone explain how to do that with the GS3?
I seriously doubt there is a way to do that. Even if there is, why would you want to!? The SD speed will be horribly slow when compared to the RAM, it'll just not be useful in the slightest.
I don't remember how but you can set up a swap file. It would be better to mount it to internal storage but that is still going to be slower. I screwed around with this quite a bit on my N1 and never was able to get better performance than not using the swap file at all.
This was useful and a major feature in the early device custom rooms G1/Hero etc. There is simply no need for it on the handsets nowadays. It was used due to the limited ram in early Android handsets to cache apps to free up main memory for the running apps. Which up until the N1 the was at Max 128MB of in built ram. You have nowt to worry about with 1/2GB of ram.

Wallaby has a 32 mb built in memory. How can this be increased. If so How MUCH & How?
Note i have installed a 128 mb SD card and have installed most of the softwares on it but my system shows low memory while the SD card is nearly 50% empty.
I have tried to use the slider in the settings to increase the momory but it slides back and is not releasing more memory for the system.
kindly advise how to increase the momory

There is a company that adds physical ram to the phone but now that prices for the xda 1 are so low I would not consider that as a realistic option. You could maybe buy an xda 1 with 64 megs of memory and a broken screen and transplant the mother board to your phone.
I think he might not know that he might free up some memmory on his devices rom. If I were you sir, I would sync my data (not backup), hard reset, reinstall everything into where I wanted it, and resync. If you have experience with hot air rework, or have a friend, you might aquire the chips and do it yourseld. THen again, if you didn't know you could add memmory to a wallaby, then you probably shouldn't do that. Be careful and good luck!
PS I'm not responsable if you junk your device, I am only giving suggestions of what could be done, not telling you it should be done!
Even by physically adding the memory chips you can get only 64meg, anything above that has to be software driven paged memory I think, bit like using a fast sd card.
I know that 128+ mb requires a driver.... I wonder if you could get in 96 somehow???? anyone done that?
I think the hardware limits direct memory access above 64.
can the chips be stacked? I thought I had read that somewhere; cut a certain pin(s) and solder/joint a second chip ontop of the origionals?????
are the user accessable ram and rom on the same chip or are they seperate chips?
could the rom size be increased? (never looked into it)
Where would one acquire the chips?
I couldn't see any swap being used on gs2, so I assume it don't have at the moment as 1gig is plenty, but if it needed in the future is it just the matter of simply creating a swap on the sdcard and android will use it automatically? Or is there a more to it.
Could andriod have a swap for phones with low memory?
there wont be a single app this year that uses ram in excess of 1gb.
goodness sake, a vmware image doesnt even use a gb !
Hello
I have an A70 250 GB HD. Is it possible to increase in some way the RAM ?
I red something about SWAP on Hard Disk , but I think is quit difficult to follow the guide.
thanks
If you device is rooted you can use one of the many swap apps in the market. But swap memory is much slower than ram.
As far as upgrading the ram you would need to solder a new ram chip I guess

Has anyone been inside their Archos, and looked what memory it uses? I know on my Dell Streak it's just a microSDHC card, and that can be changed for a larger one, following some already defined steps.
Short answer: NO
> Has anyone been inside their Archos, and looked what memory it uses?
y - there is a thread about the mainboard in general-forum - CPU+GPU+RAM are all in one chip (SOC)
So u can't do anything else then use SWAP / CompCache - it's not possible to upgrade ram sadly.
Really the only thing I miss at my archos.
> I know on my Dell Streak it's just a microSDHC card
don't believe that - the microsd card is propably NOT for ram usage but just for memory extension as it's used on our archos devices too.
sdcards are not fast enough for acting as real ram.
Also it would destroy the sdcard in a short time as they just have a limitet count of read/write actions till they die. And ram reads/writes data like all the time...
> I red something about SWAP on Hard Disk , but I think is quit difficult to follow the guide.
Well if u use UrukDroid its quite easy - go to UrukConfig -> Swap or CompCahce and activate the service / start it.
Be aware that u can't use swap values much greater then 64MB without setting swap to a file... as its on a seperate partition by defualt wich is not much bigger (don't know the exact value)
Also keep in mind the memory u gain is MUCH slower then the normal ram. so Don't set values too high as u will slow down your device.
Hey guys,
I have an HTC One V, which is a pretty low-mem device at 512MB RAM. I've been using a normal 256MB swap partition on my SD card with swappiness set to 100 and default minfree settings. This has already given me fantastic results, now I can switch between 4 running programs without having to reload any of them. Before the swap script 2 was the maximum, and even that wasn't always true. Basically I had no multitasking.
Now, I've been checking my memory usage in detail. It seems that when idle, there is about 80MB of free RAM, and around 80MB of swap space is being used. It seems that even though I have 256MB of swap space available, Android never really goes above using ~80. Is there a setting I can fine tune somewhere that would lead to better use of the swap space? From my limited understanding, it seems that in theory Android could store at least two or three more background apps on the swap partition instead of killing them. Which, of course, would lead to much better multitasking.
I'm also aware that using the full 256 megs might actually hurt performance, but I still want the OS to use more than 80.
Please don't flame me if this question has been asked before, I tried to search, but I only found threads discussing the value of vm.swappiness.
TRY TO USE KERNEL TUNER.
AS WELL AS INCREASE SWAPPINESS TO 128 MB.
BUT OS TAKES ONLY AS MUCH RAM IT WANTS U NO NEED TO WORRY THAT IT IS NOT PROPERLY UTILISED.
Hit thanks.....

Disclaimer: This is somewhat speculative.
The vm.swappiness is in principle what you are looking for, talking about Linux swap. Unfortunately, for you right now, the Andorid uses "application level swapping", i.e. the Android ActivityManager (userspace task) kills of app's when the memory gets low. Since Android normally don't utilize swapspace, there's a possibility ActivityManager doesn't looks at the size of the total virtual memory (including backed by swap), but only the physical memory installed. If so, it will continue killing app's at the same memory threshold as before, despite of the increased virtual memory size, hence not utilizing the increased virtual memory particularly well. This sounds as what you are describing.
You'll need to check the source ApplicationManager.java to examine the internals here.
Hi all! Running PAC ROM JB 4.2.2 LOVE it.
I utilize a root-only app, a swapfile RAM expander. Utilize my extermal SD to create a 1.8GB swapfile that the system uses as VM.
Any thoughts on this, does any other DInc developer/modder use this as well?
My phone's memory capacity now reads at 2.5GB. Runs that way too!
Bring on any and all feedback.

sounds like a bad idea to me. flash memory only gets so many writes before it cant be written anymore.
