Hi,
I have a noob's question :
I'm using Qtek Magic 32B rom, I want use virtual ram then I use recovery 1.5 to partition my 4gb class6 sdcard to 3 partition. I see that my phone faster but when checking memory status in Advance Task Manager, I see that no change after do that. I tried resize swap partition and having no change. How to check all memory in my phone ? And why increasing size of swap partition doesn't increase virtual memory ?

Is it possible to change Storage/Program Size without Upgrade or change the OS?
Current Storage is 40MB and Program size is 43MB.
Change it to 25 for Storage and 58 for Program.
So, is it possible using any utility?
See u all.
No way its a hardware issue
well thats ur defalt storage cant mess around with the phone mem
The program memory area (or RAM which is 64 MB for Gene ) is fixed you can not change it any way. The storage memory (or ROM which is 128 MB)is the area which is left after your device is flashed it with a ROM image. So IF you flash your ROM with some other custom ROM, the storage area will be different. but program memory will be unaffected
hi there
hope u people are fine...
my question is what is the max size we can keep on ext. partition on sd card
i have 8 gb card
currently i have 512 mb on my ext partition but still whenever i install more apps it give error memory is very less and phone works very slow it is always aroung 54- 72 mb only to before starting any app or game i have click on task killer
is there any solution to this...
or any rom which can solve this isssue currently running 1.5 froydvillain
because of this issue i have started hating my hero
please let me know any solution to this
Simple solution back up ur EXT - partition & format it. Otherwise Download Quick system info App from the market & Check your App2sd is working correctly or not ..
thanks for your reply
what should be the size of ext3 partion if i have 8 gb memory card ???
512 mb or more
i think it doesn't matter you can make 512 or 1024 Mb also .. but just too not sure
the size of the ext-partition should not be the problem...
format your sdcard (back it up first)
and be sure to create an ext2 partition just to be on the safe side
some kernels do not support ext3+
(not sure if ninpo's kernel does)

Should support it, but use EXT2 to save the life of your SD card
Your dalvik cache is filling up your on board memory.
okay, so i just flashed Kyrillos' ROM (7.0, then upgraded to 7.1)
now i want to partition my SD card to create SWAP, and also to create a partition to add extra space to the internal memory (what is it's name, again?)
i don't know too much about what type of partition to do, so can you guide me through the process or give me a link where i can read further?
also, what are the recommended partition sizes?
PS : i have a 4GB, class 4 SD card. and i just downloaded minitool.

you can flash g3mod kernel and do partition in uer sd card.mine is 8 GB Card, Class 4...I have 1024 as Ext Size and 256 as SWAP. so the choice is uers.

I've been looking for that too , Thanks
okay, i didn't know i'd need a card reader :/
i don't have it. any way to partition it using the CWM?
and what sizes do you recommend? i was thinking maybe 128 MB SWAP and 512 as the internal memory size.
and do i have to flash the g3mod kernel? i'm currently running 2.6.32.9. this came with Kyrillos' 7.0.
wait, i'm getting confused now. when i flash Kryillos' ROM 7.0, does my kernel also get changed? or am i running the stock kernel?
and the CWM i'm talking about is just.. recovery. the one that i access using vol up + vol down + home key + power key.
that also has partition SD card option under advanced > partition SD card.
will this do or do i have to flash g3mod kernel?
Once you flash Kryillos' ROM you are no longer running the stock kernel
CWM is ClockWorkMod Recovery and it comes with the ROM and so it's different (Google it)
And about making a SWAP, well , you might wanna read this -
"1. An Android swap partition must live on your SD card. SD cards are very, very slow memory. They are 100 to 1000x slower than a SIM. They are 10 to 100x slower than a hard drive. They are marginally faster than a network connection. When an application is “swapped out” it is copied into this very slow memory, and copied back to physical memory when it needs to run. On the other hand, when an app needs to be restarted after being terminated by Android, it is loaded not from the SD card but from the device’s (relatively) fast physical memory.
2. When an Android app is terminated because of low memory, it decides what information must be persisted to represent it’s state. This can be very, very small. For example, it might be an integer index into a database. When an app is moved into virtual memory, the OS has no idea what’s important. It just moves the application in whole. It can’t be smart about it.
3. Having swap actually prevents the native Android memory management scheme from activating. The system sees memory and doesn’t distinguish between physical and virtual. It will therefore prefer swap over the native Android memory management scheme, and won’t activate the native scheme until swap is full.
4. Having swap requires some overhead of system resources."

Nice and informative.
Hi there,
I never dealt with creating swap partition. I'm using latest SwiftDroid now and like to know if it uses swap automatically. If not, would it be advisable to create one? How do I have to do this? Which size should it have and does SwoftDroid ASIS recognise it rigth?
I googled a lot and search in the forum, but didn't find helpful information.
Thanks

using swap isn't the best idea as it kills ur sd card faster.
also a lot of people use about 200mb swap partition to about 300mb swap
partition..
u could get the app from the market ( swapper2 for root users )
or read this thread!!
http://forum.xda-developers.com/showthread.php?t=1317362
Mur4ik recommends swap 256MB for previous versions of SwiftDroid, so I think that is also applies to ASIS. ASIS can use swap automatically (no need to use swapper app) if you create swap partition as third on sdcard (second should be ext - in newest recovery you can create 2MB ext3 partition).

Okay, now slowly. I flashed my phone with Mur4ik's KDZ Method before installed SwiftDroid. So there should be 150MB for system,64MB for cache and 234MB free internal storage. Are the 64MB memory for swap? So that SwiftDroid always uses swap but with internal memory?
Now I don't understand what you say about second and third partition and what exactly Mur4ik suggest for his ROM. They are both an SD, aren't they? I use a 16GB class 4 SD card. So what should I do to get best performance with ASIS?

150MB for system,64MB for cache and 234MB free internal storage <- it's internal storage of your phone, system is just system, cache is for files downloaded from internet, internal storage is for installing your applications.
On sdcard you should have primary partition (fat32), ext3 and swap (linux swap type) partition. The third will be automatically used. See thread mentioned above or copy everything from your sdcard to you computer, reboot phone into recovery and creat ext partition and swap partition (in that order) through recovery. Then reboot phone and copy data back from computer to phone's sdcard.
Ok, i managed to create 256MB swap partition.
So what do you say is the best swappiness value? I read that 60 seems to be to high?
PS: How can I see if swap works?
I leave mine at 60 to see If it works type free in a terminal on the phone
Ok it works. Terminal shows me that the phone uses swap. But I also recognised it by playing some games, which worked laggy before and now run very smooth.
About swappiness: I read that 30 seems to be the best for our phone?
ASIS set swappiness to higher value (I believe 60) - I've changed it to 30 in previous versions but now I just left it as it it. I don't see any difference.
Yay! no more third person software :3, native swap.
Thanks :3
i heard that you can edit a partition on the sd card to Increased the ram since the boot, space and storage is all on the card... i hear you should be able to edit some them but i have no idea if it can be done and if it can what Tool
i was using MiniTool Partition Wizard Professional Edition v7.5

You are confusing ram and rom. Ram is the memory that the system stores the active stuff. It is volatile and loses everything when the power is off. The Nook Color comes with 512MB ram and that cannot be changed. ROM is non-volatile and keeps whatever is written there even with power off.
ROM is what is on the SD partitions for SD installs. And you can change the size of the partitions on the SD, but it is difficult to do with windows applications like Min-Tool once you have added data to those partitions.
If you use my newest image file (rev4) I have set it up to give you larger system and data partitions for larger SD cards so you don't have to do anything yourself.

i know what the ROM and RAM is
to help you out about what i mean........ after the img is burned to the card there are 3-4 partitions on it..... well a friend of mine who has the same set up was saying "Theory-Wise" since all the CM7 &/or CM9 setup and so-on is on the Card/Runs from the card... the RAM that you use to run games when using CM7 is also on the card so that means the card also has RAM on it(since the setup is on the card) you can Increase the RAM by messing with the size of the partitions......... can this be done???
as for the latest img you was talking about... can u give me a link to it?
Not everything is on the card. The ram is still on the device and not changeable. It uses the same ram as the internal rom does. There is no ram on the card.
The link to my new image is in my tips thread linked in my signature. See item B2 in the second post.
