Is it possible to extend RAM in my Archos 80 G9? I'd prefer 1GB instead of 512 MB, I run out so often from available memory and the whole system stucks for long seconds because of this.
Thanks.
Unfortunately not. Tablets are not like desktops or laptops where you can simply add another stick of ram. They run off SOC's (System on a Chip) where everything is integrated onto 1 chip for convenience. There is no way to upgrade the ram chip on these.
You can add swap, but the performance isnt gonna be as good as 1 GB ram.

Yes you can...
But don't swap if you don't have HDD model... (Or swap on network or USB hard drive...)
Write cycles are too limited with flash, internal or not, memory and your tablet (or SD card if you swap on SD card) will wear out quickly!
I have a HDD model, but I don't know how to add swap...
Can anyone explain it?

First : You have to be root
You can do that with a few commands (in a shell script)
You can find scripts that can do that searching on this forum...
You can also download a Swapper on playstore (Swapper, swapper2 etc...).
Thanks everyone.
Great! I hope will work on my 101g9 250gb.

Hello XDA forums,
Recently I installed Urukdroid 1.0RC2 on an A43 8GB model, and I noticed how my device only has up to 7GB of space. I was just wondering where the other 1GB is because I don't want to have wasted space sitting around doing nothing.
Thanks for your time.
This "problem" isnt a problem
its always the same: if they write 8 gb, there is formatted only 7-7.3 gb
look at your hdd on your computer
Hello and thanks for the quick reply.
Actually I do understand the deal with the 1024mb = 1gb, but are you sure that it is supposed to read 6.95 gb (that is what it says in Linux when connected)? I'm pretty sure it should more or less be around 7.4-7.7.

Okey thats pretty much
hm.. than its because urukdroid's formatting
what did you select in urukdroid installation progress?
EDIT: You said thanks, psst... push the "Thanks"-Button don't hurt
@denwaotoko:
What do you think where the system itself is hostet?
Right it is on that 8GB internal memory.
It has 3 Partitions ( without Uruk ) which are for System, Data and Rest.
@fzelle correct.
as far as I know, the kernel splits the 8GB in two "virtual" devices which of one is 512 MB large and the other one 7,5 GB.
The first virtual device is /dev/block/mmcblk0 which contains rawfs (boot), swap, system and /data partition while the second (big!) virtual device is /dev/block/mmcblk1 and contains only one fat32 partition (internal storage)
so you only get 7,5 GB which in the end is about 7,x GiB formatted storage that can be used (don't have my A101IT with me so I can't give exact numbers)

Yes I do realize that, so is the 1gb of "lost" space just hidden?

Jap, exactly
We can be proud of the fact that android uses only little memory space,
Windows for example use 20 gb
Alright, I was just expecting that it would show up in a partition manager when connected to a Computer.

No, it doesn't because the device only shows /dev/block/mmcblk1 and mmcblk2 to the computer, where 1 is the internal flash (the last 7,5G of the internal mmc as I explained before) and 2 is the external microsd.
Hello anybody who can help me and other people understanding what we see in applications which show memory info.
I want to understand why "meminfo" shows total RAM 335Mb and Internal phone storage: 420Mb (it is on my phone).
Official info from http://developer.sonyericsson.com/wportal/devworld/phones/phone-overview/xperia-mini-pro?cc=gb&lc=en says it should be the next:
- Internal phone storage: up to 320 MB
- RAM: 512MB !!!
One of my thoughts is that the part of memory is used by video-card
Please explain me why it happens
Some is dedicated to the graphic and some more is reserved from the system. The total is 512, don't worry.

Think of the Android Operating System as a Virtual Machine on your phone. It needs some RAM in order to work.

Can you modify the values besides a VM usage ram ?
No. What you need in order to have more "system memory" which actually is part of the RAM itself is swap. Swap creates a partition on your sd card which then is used by the system to store temporary data. The thing is that its a double edged knife. NAND is 100 times faster than your typical SD card, so loading apps and/or part of the system on your swap partition might end up in a slower overall phone. But we wont have such a problem with our devices, because the system itself doesnt take all that much storage itself.
The only device so far that i know, which had a problem with storage was the Desire Z i own, when you wanted to flash a custom sense 3.0 rom. Then it needed different partitioning in order for the Sense 3.0 to fit into the device.(the device isnt a sense 3.0 device by default).
If you have many apps that you cant seem to fit in the 320mb of free memory, i recommend you install an app2sd application.
I bought an Archos because I thought I could install Linux. I have a problem with the ubuntu.img which is 1.9GB and the /data is only 1.5 at its max (800mb after installing some Android applications). The question I have is how can I increase the /data partition? Does it come from the 250GB, if so, how come it is so small? If not, where do I get that space from? I saw some postings on how to increase but the procedure does not work for this particular model: Archos 101 G9 1.5gh 250GB hdd. If somebody needs a tester please contact me.
...
I have the same problem and I can´t figure it out!
The flashversions don´t have these problem, because they have all of these space, but the HDD version, just 1,5Gb... In another thread I try to figure out how to mount the HDD for more app-space, but the HDD is slow and it would be very inefficient, soo you should change the HDD to a SSD...
If there is any option without modifing the hardware let us know
Other Thread
This would be the other thread...
We´re trying to get more app storage at the HDD version!

250GB is hdd storage, Android uses it to store your files only (videos, music, documents etc). Data partition (system files, apps, app data) is in flash memory which is much smaller.

Is there any kernel (GB, ICS) who supports a swap partition on xperia ray to get more ram? I am wondering why not all ROMs support swap by default
Thanks!
PS: I know the disadvantages of swap partition on a slow SD-card.

Few good reasons why swap is not enabled by default:
swap=amazingly slow (even on a fast sdcard)
swap makes your sdcard dead soon, as it read/writes a lot
So if possible, please stay away from swap, manage your memory in another way, like minfree settings or by disabling memory hungry programs.
If you are in ICS, than don't forget the light GB alternative...less memory consuming and really fast.
Also a good thing is to use the tool : autostarts
With this tool, you can disable triggers that automatically startup application in the background, like gmaps and other crap.

Easy sollution - Swapper for Root
I found a app who installed a swap file:

Could you define 'soon' please? Due to the wear-levelling on cards it would take years for this to happen. Each time something is written to the card it's written to a different free location to ensure that you don't 'burn out' one section of the card prematurely.
From a report done by Toshiba on flash memory you could: “completely write and erase the entire contents once per day for 27 years, well beyond the life of the hardware.”
Unless you've completely filled up the card and are swapping data continuously then it's a safe bet that your £20 card will still be working perfectly when you've thrown away your £200 phone.
And one more downside of swap partition: battery consuming. Try zram instead.

How can I enable ZRam?
Do I also need a special Rom/Kernel?
I use GB with Aire Kernel.

The kernel doesn't support swap by default.
I would like to ask u,my bro K900
I don't understand Swapper2, I look tutorial for swapper2.
But they said
" Swapper preferences: (for kernels that doesn't have swap partition support)
Run swapper at startup (put a check)
Swap place: /sd card/swapfile.swp (you can place it in a folder if you don't like a messy sd card structure )
Swap size: MIN: 10 MB MAX: 256MB RECOMMENDED: 32MB (choose any)
Swapiness: RECOMMENDED: 10MB SYSTEM DEFAULT: 60MB MAX: 100MB (choose any)
Safe unmount (put a check)
Safe remount (put a check)
Advanced preferences: (for Kernels that supports swap partition only)
Use swap partition (put a check)
Swap partition: /dev/block/mmcblk1p2 "
Plz, i don't know about this. sorry for my english bad.
Why do you need it? Besides i've never heard creating a swap partition on the internal storage given that the U has no SD card slot.

But It can create swapfile.swap on internel storage. I would like to ask more memory on my XP U ( I also used RAM Manager & Super Manager ).
My memory always 80 MB to 100 MB. How to do ? Plz. my bros. Other App?
80-100 is fair enough. Remove the bloatware and it should be~150mb free at all times. Anyways free Ram is wasted Ram. I still don't think you need swap
Sent from my ST25i using Tapatalk 2
I have usually 170mb ram free.
have you ever heard of v6 supercharger?
anyway I don't think creating a swap is necessary since 512mb are enough for the heavier task this phone could do, I usually have around 150mb free ram, and that's enough to keep browser, music player, and another whatsoever-might-be-needed application

Close the running services. If you're rooted block apps from re spawning on their own using rom toolbox. This keeps the RAM free

I think it isn't a good idea. The swap can kill the sd cards easy, but U have internal storage, so you can't replace it. So it could be an expensive fun.
Services are restarting itself again if I stopping them. And I don't have root.

swapping? i dont think we need it even i have 80mb of free ram even after reboot and less than 40mb without clear memmory, i use my phone heavily playing game HD browsing music watch movie etc etc etc and i have not reboot my phone for a week, 122hours exactly there is no problem i found
yep this is smart phone and it should be know how to manage it's own ram
