[Q] Possible to make 512 Rom 1024 Rom?

I have a TMOUS HD2 1024 from the US go live release (red reset button). I have been using various Android builds for a few weeks now and love the MDJ's CyanogenMod 7 v2.2 (11 JAN). My question is this:
If I use one of the builds made specifically for the 1024 ROM will I see better response times? I know they are compatable since I am already using a 512 but more importantly would there be any benefit using a ROM designed for the 1024?
If there is a differnece is there a way to modify this build so it takes advantage of the full 1024 ROM? I have seen discussion related to changing the size of some spicific files that modify storage sizes but am very novice to phone edits and quite cautious. Any help would be welcomed and if this has already been discussed a simple link would be most appriciated.

With 1024MB ROM, there are no advantages in terms of speed performance.
However, you do get space advantages.
If you flash a 350MB ROM, 350MB is being used by the system partition, a small amount is used by the boot partition and cache, then the rest are all userdata partition, which gives you around 500MB free space to install apps and store user data. (SMS, etc)
People with 512MB ROM, 350MB is being used by system partition, minus boot, cache, you have like around 50MB to 100MB left which isn't much for apps and user data. Which is why they need to use A2SD+ or DATA2EXT or similar methods of increasing userdata storage.
Try using Clockwork Recovery. You will have ALOT of free space. Even if you don't do A2SD+ partition, since MDJ's Gingerbread Cyanogen uses less than 150MB for system partition.

it would be usefull if you told us exactly which desire hd rom, how you are running it (daf, cwm, sd card), and whether you have an ext partition on your sd card. Oh, and which phone you have, regular or tmous.
Sense roms are big, they take up a big chunk of the nand, so it is almost always essential to use app2sd and/or data2sd. (read the thread for the rom you have to know which it supports)
More accurate info = more accurate help.
rubbish info = rubbish guesswork help.

Thanks for your reply...
here is my details..
ROM : LeoRCMix S v.1.5 (RCMixS v.2.0) [Sense 2.1+3.0]
Running using : CWM
Phone : HTC HD2
Im using : TMOUS
I know i have to use app2sd/data2sd.. but im not sure how to config it.. even i tried to do but im struck with boot screen..

ok, so it should only need a 200 meg system partition, so my guess would be that you haven't set up the 1gb ext partition? you can do that through cwm (backup your sd card first, it will get formatted) and
but im not sure how to config it

you dont have to. it does it itself so long as you have the ext partition properly created. I also think that if you DONT have the ext partition set up yet, you will probably need to reinstal the rom after you DO set it up.
So, summary, , , question 1 - do you have an ext partition set up?
(Also, and this causes a lot of confusion, , , when the system uses an ext partition, it DOES NOT show the extra space in the available memory count, but it does get used, , so for example my phone shows 210MB or so free internal space, , , i install a 10MB probgram, that goes down to 200, BUT after i reboot, it goes back up to 210, , because the prog has actually installed to my 512MB ext partition, not the 210 internal space.)

Yes i have ext 1GB partition and i created using CWM and i have 400MB patition layout.. but still i am having low memory issue.. can you please tell me how to use data2sd with respect to thr above rom..

then you are wasting 200 meg, , that rom says in post 1
EU and TMOUS: 200M system + 1GB EXT partition
Click to expand...
Click to collapse
that means you have 200 meg empty in your system partition, not being used.
Stuff that you install do not get installed to the system partition, nothing (or at least not apps / settings) gets put into the system partition, except the system at installation.
Do a full cwm backup, reflash using a 200MB partition layout, reflash the rom to teh new layout, restore your data and sd-ext partitions from advanced restore (in cwm) and you will recover the 200MB

Thanks a lot... now i understood wht is system and data memory.. now i got 200mb internal memory.. thanks again

same problem
i have a nand of 4.1.2 in my hd2 its pacman
it shows system memory only 13mb, i have removed all apps i installed earlier but still no space freed, can i atleast get the same 150mb back which i had earlier i.e any way to wipe all data on it/hard reset it?
is there any way of expanding the memory? because after i have installed 10-15 apps the memory vanished(even though i moved the apps to sdcard using app2sd) does that means i can not install more apps any way??
p.s i am a new user of android dont know how to install new rom etc so please explain the solution in simple steps.

[Q] How create/make bigger app partition Android 4.0.3

I have LEO T8585, and when i flash Android 4.0.3. NAND (http://forum.xda-developers.com/showthread.php?t=1354267) i have only 100MB for apps. I tried this HD2 Android NAND toolkit to make partition bigger but no luck.
No matter what size i choose i'll get same size for downloaded apps - 100MB.
Im not total noob flashing NAND ROM-s , but do i miss something?
Or is it possible to make this partition bigger?
Thanks

First, the space shown as available doesn't include the system, boot or cache partition size, only the data partition size, and since during flashing, the data partition size is set to be whatever is left over after the rom is flashed, the only way to increase data size is by reducing the system partition size, , but then of course the rom wouldn't fit (because you flash the system partition to be only fractionally larger than the size of the system folder contents, if you flashed a larger system partition, the extra space would be wasted, unused by anything, example put a rom requiring 150mg onto a 250 Meg layout and you lose 100mb)
Secondly, if you set up an ext partition on the SD card, the rom will consider that internal memory BUT (on most roms) wont show it on the available internal storage calculation, but it WILL use it as internal.
third, the 4.x roms are still beta, and vary as to sizes required, whether they have ap2sd+ built in or whether you need to manually install and configure it. If you are looking for a rom you can keep as a daily for a while, wait until 4.x is a few more betas along.

Thanks!
Thats what i thougt. I made minimal part. 190MB and got 100 extra. My ext. on SD is 1024. For now its ok. And this 4.0 beta 10 it is very nice ROM, looks stable and smooth on HD2.

[Q] How to flash?

Hello guys i have a T-Mobile HD2. And i know its has 1 gb rom.But the toolkit for hd2 supports only 450 mb max partition. How can i make it 1 gb? Thanks,,

no one knows :/

that 450 is the system partition only, if you made a 1gb system partition, you wouldn't be able to install anything, and you would waste a heap of space. when you setup the partition layout, anything left over becomes the data partition. so a 450 meg partition layout would leave about 550meg as the data partition for your user data, apps and such like..
Also, there's no point making the partition bigger than you need, ,if you flash a 200meg rom to a 450meg layout, you will lose the 250meg difference, it wont be used by the data partition, it will be wasted space.

You can use clk1.5 to increase the system partition to that size in settings>repartition.

[Q] swap?

can someone tell me what is the swap, swap partition? please help!

Android is using SWAP-Partitions like "internal RAM". It is not exactly the same as internal RAM, but very close to it.
So you can increase your internal ram by using a swap-Partition.
Swap-Partition is a separate Partition on SD-Card. Mostly the last partition on sd-card.
For example:
16gb - SDCard---> 1. Partition FAT32: 14 GB, 2. Partition: SD-EXT: 1,5 GB, 3. Partition: SWAP: 500 MB
If you have a swap-Partition on your sd-card AND Android is told that it should use SWAP (e.g. by using an init-d-script or playstore-app "SWAPPER") - Android will use the amount of memory on SWAP-Partition as internal RAM.
But it is not exactly like: 1GB Internal RAM + 500 MB SWAP = 1,5 GB Internal RAM - > that's not true.
If you activate SWAPPING you have to decide which value of "SWAPPINESS" you want to use.
Example:
Swappiness 30 means:
70 percent of all write-actions will be on internal ram and 30 percent of all write-actions will be on SWAP-Partition.
If you set Swappiness 100 means:
ALL write-Actions will be on SWAP-Partition --> Internal ram is nearly not used any more ("nearly" becaus some things in android are using internal ram further on).
But you have to be careful: You need a very fast Sd-Card.

thanks very, very much!! Just one more question.... What is the chache and dalvik cache??

Dalvik Cache is a List in which all apps and the path to find those apps on your phone are listed. With this list in Dalvik Cache, Android
is able to find and start Apps and other files faster than other Operating Systems would do.
You can erase Dalvik Cache, but on the next Restart of your phone - dalvik cache will be rebuilt automatically.
Cache is a partition into which all apps are writing different things when they are started and when they are running.
This data is only temporarily needed. There are some apps in playstore that are able to erase cache in order to speed up system a little bit.

so does the SWAP make your phone little bit faster?

It depends on how you are using your phone.
If there are many apps running in background that must run in background and stay there all the time (e.g. taskkillers, battery-monitoring, antivirus-software, whatsapp and so on) - very much of internal ram will be reserved for those apps.
As a result : For all other apps that are not staying in internal ram all the time (e.g. games, office-apps, and all the other stuff that can be downloaded from playstore) - there is much less internal ram available for.
This may end in lower performance of your phone generally.
In my case - i use a 300 mb swap-Partition and my phone is faster than without it.
But it depends on the speed of your SD-Card and the kind of swap-activation, Swappiness , readahead-value and so on if you want to make your phone faster by using swap.
Some people say, that zram-swapping is better than swapping with a swap-partition.
I can not say that too, my phone is slower with activated zram instead of activated swap-partition.
zram means, that a part of internal ram is reserved for a swap-partition instead of a swap-partition on sd-card.
So during the usage of zram you have less internal memory free for your apps again, BUT android will swap some system- apps to zram.
Sometimes this makes your phone a little bit snappier, but in my case ist slows down everything.
But SWAPPING BY swap-partion is worth a try.
