[Q] How to decrease RAM usage while creating a ROM? - General Questions and Answers

After testing many roms,i finally recognized that these all roms have 300 mb up RAM out of 490 or something..
So,i am also making a new ROM..How can i decrease ram usage and increase ram memory to 300 mb like only..
Therefore,when people will use my ROM,they will automatically get 300 mb memory.

Where memory goes to?

Hi everyone! Updated to Darkforce's ROM, but have same question for another ROMs.
As I know Universal comes with 64 Mb RAM and 128 Mb ROM. Well, fine. After installing WM6 by DarkForce "Memory" in "Settings" reports:
Storage Program
Total 43.50 Mb 48.88 Mb
In Use 10.13 Mb 27.87 Mb
Total 33.37 Mb 21.01 Mb
I allow that Windows hiding real size of RAM, but is it using 45 Mb real?
And what about storage? I guess that some ROM memory eats up ROM (that I updated), that's nearly 70-80 Mb. And something WM.
My guesses are right? If that so, how working devices with less memory (like 64/64)?
And what does mean Extended_ROM in "Storage card" option. What is it for and how to deal with this? Why on WM5 weren't that?
Sorry for n00b question.

288 MB ram? but where to find it?

Hello guys
I already used the search and looked around on the internet using google and ecosia... but it didn't help me... everytime i am looking for the answer to my question: "HTC says that the touch pro has got 288 MB of ram but there are only displayed 193 MB and my free memory is about 65 MB (used 128MB)" i only find some roms that say that they have a lower pagepool... but that does not help me in finding a solution to my problem that i can't access the complete ram...
is there any workaround for this issue? a classmate found a rom for his touch hd2 which solved the same problem as mine but on his hd 2... now i ask you for a solution on the touch pro.. please help me ^^
i think you didnt think about the fact that the OS needs ram too ... but you can try ROMs without manila that spare ram; which ROM do you actually have?
I'm using the latest energy rom, its all fast and very smooth animations.. really great :]
but no i think you didn't understand me... the hardware ram is 288MB according to HTC. The memory manager shows me that there is in total only 193 MB available. 128 MB of these 193 MB are used... the rest is unsused memory... now what is about the rest of the 288 MB ?
the osram usage is included in the 128MB if you trust the task manager ^^
so what is my phones problem? are there maybe some limitations that can be solved with some registry changes? on windows vor PCs you can disable some parts of the ram that they are not used... can this be a possible problem on my phone? when I was using the O2 branded original rom there were 212 MB usable 80MB used and 132MB free... i really can't imagine why ._.
ok, i see, but what about the memory that is needed to store the files that will be used restore the files after you do a hardreset?
Do you know nue storage manager? Try it and look, how much drives you have installed in your memory... which you dont have in normal use
do you know the difference between ram and rom? operating systems are always installed on roms and the ram looses its data during a hard reset.

Yes, hardware RAM is 288 MB. In your case (with Energy ROM) 95 MB of RAM is used by the OS itself, so you have only 193 MB RAM available. You should know that the rest (in your case 193 MB) depends on the ROM cooker. Energy ROMs are known for not being RAM friendly, actually NRGZ28 stated once that he doesn't care for free RAM. That is the reason you have only 65 MB of free RAM. For example I'm using CRACING ROM and I have about 110 MB of free RAM after reboot, if Sense 2.1 is enabled. If I disable it, I have about 130 MB left. When I was using offical HTC ROM, I had more than 150 MB of RAM - that is with all today plugins (TF3D for example) turned off. Of course, if I disable HTC dialer (that has a video dialer and other options) and switch to ordinary WM dialer, I can free even more RAM. Pagepool is also very important - it is a special area of memory reserved for loading apps into from ROM. I think that the default pagepool is for Raphael 12 MB (that means 12 MB less RAM), but most of the cooks sets pagepool to 20 MB or more - that means 20+ MB of RAM used for faster loading of apps. That is why your phone is so fast with Energy ROM - it has a veeery large pagepool, but you have very little free RAM because of that.
So, to make things simpler, most of the RAM is used by the OS, GPU, TF3D/Sense/Titanium/SPB Mobile Shell/some other UI app, pagepool, dialer, other background services/processes etc. So you just have to decide what ROM to use - there are some ROMs (like yours current) that are very bad for RAM, but there are others with 120 MB+ or even 150+. You can also cook your own ROM and maybe gain 180 or more free RAM.

Great comment! Don't forget that the Radio will also use up some memory and especially with the HD2 there seems to be a Radio (original t-mobile) which uses almost 12 MB less than others.
However, what is your problem? You are concerned about battery life (keeping all that RAM happy and addressed) or you have a specific application which wont run. I didn't check the latest NRG ROMs but he ran pagepools up to 26 MB. It's one of the first things I check with a tool called pagepool changer. I adjust mine to 16 meg which is/was supposed to be the sweet spot for the Raphael/TouchPro and never had any problems, speed or memory issues.

If the question is adressed to me, and not OP, I need at least 90-100 MB of free RAM because I heavily multitask. That is the main reason for being WinMo user. Besides, ROMs with low RAM are usually battery hungry.

My answer was addressed to both. I also multitask though mainly Word, Excel and chat and as long as I don't open iGO all is running well (and you don't multitask while driving anyway ).
Let me check how much free RAM I have. ROM is in my sig, modified the PP from 26 MB (NRG's default) to 18 MB, Manila 2.5 with added Program Tab and Max Manila 2.7SE fullscreen on top. As you see I run the xperia X2 task manager because I too like to know what's left in RAM.
The screenshot is after ~ 4 days after the last boot "active sync'd"

Well, I do multitask while driving. For example, iGo is running along with browser. When I need informations about traffic on main intersections (from the video cameras in my city), I open the link for that particular intersection via browser and then Streaming Media plays that clip. In the meantime iGo is running in the background of course. Lot of RAM is required for these tasks. And what if someone calls me - the dialer is also RAM hungry... Besides, often I use GPS whilst walking. This is just an example - like I said, I'm a heavy multitasker.
humm okaaay... but on my older eten glofiish x650 with only 64MB of ram I had about 24MB of free ram though windows mobile 6.5 (only tried it out ) so windows mobile can be 40MB small... and although it seems to run very well...
humm what do you mean with radio? the music radio or something like gsm radio module for windows mobile? (sry 4 my comprehension issues but i'm from germany ^^)
talking about the radio rom, which can be updated / changed like the OS and make it possible to get better phone reception or gps or ...

I really think that you should read XDA Wiki, as much as humanly possible, in order to understand basic things about WinMo. Cheers, mate.

To increase RAM on Tablet PC

Hi I have BSNL Penta IS701C tablet PC. IT has 1 GHz processor and 512 MB internal Ram,4GB Internal Storage.
But Actually It shows near about 350 MB RAM outof which ony 100 MB free and about 250 MB is used I have no any apps installed. And Also It shows 530 MB internal storage And 4 GB internal storage. When i starts any application ram space decreases and for multitask it becomes less free below 60MB of 100 MB free. For google chrom IT gets hanged due to no free ram. Wht to Do ?

[Q] [REQUEST] "bbm"

Can anybody make a bbm app which is much faster and less ram consuming !
As like "whatsapp+"
The official bbm app consumes more than 50 mb ram, which is too much for a 512 mb ram users !
It would b great if anyone can do it.
THANKS

2.6 Kernel with increased heap size limit for Pico?

Hi,
Simply... I would like to find a way to increase the heap size memory limit for my Gingerbread system, as most applications crash at around 20 MB of memory usage (even though my device has 200 MB free ram).
Do you know a kernel that allows apps to use more memory?
Best regards
