why storage ,not ram increase ?

Hello everybody ! I have a question for the smart guys around here : i have read a lott o this threads and it seems to me that you have an obsession with the storage memory. Why is so important to have a big storage when you can put on your device a micro sd card ( mine is 2 gb) . I hope someone to work on the running program memory on a rom. is it posible to unlarge this memory from a rom ? sorry for my bad english

There have been a couple of devs that have tried to utilize storage (ROM) as a cache for RAM to increase performance, and it dosen't work (impossible really, two different types of memory). If you search in the development and hacking forum (use google) you can find the threads (they are kind of old). Really there is not alot of trickery you can do to get RAM up in a cooked rom.
The reason the devs try to free up more Rom storage is that apps loaded on the internal ROM generally run faster then those coming off and SD card, also certain programs do not run well if installed on a sd card (dialers are a great example of this).
There are several lite roms available in the forums and generally these roms will have much higher available RAM (they are loading less programs at startup). If you like you can take a full rom and disable some of the programs at that automatically startup (ftouchflo, htc home, etc.) and this will generally result in more available RAM.
However besides having less apps running (and thus less funtionality/ease of use) there is very little you can do to free up extra RAM on a PDA. I would recommend use download OXIOS hibernate and close apps,google xda oxios cab and you should find it. This app can be run (I assign it to button 5 and hold) to free up extra RAM that closed programs have not realease. Also make sure that you are completely closing programs not just minimizing them (take a look at memory or task manager once in a while) if you have a problem remembering to do this change your settings to completely close apps when you tap the X button. If you do these two things you should not have an issue with running out of RAM.
As a note you can run lots of apps with as little as 22MB or RAM at startup, in fact several Rom's (notabley Kin0kins and to a lesser extent Farias) set aside free ram to speed the device performance (it is no longer available to run apps). These Rom's generally use 6MB page pools and have file caches setup as well (I'm not sure if farias has a file cache). These types of roms (or other roms with the page pool and file cache changed) are generally much faster than other roms and I've still never run out of RAM (as long as I use task manager to close apps I'm not using and run oxios once in a while).
Hope this helps

I second what aaron said.
When I was deciding how much pagepool to set on my new ROM, I ran tests to see just how low my FREE RAM could go before I had problems.
I had to EXAGERATE the number of simultaneous applications + run IE with tons of webpages to go down to 2mb of free ram. Only a bit later while browsing on IE did I get a "LOW RAM" error.
Before the LOW RAM error, my phone was running just as fast as when it had 20mb of free ram.
What makes the phone slow is mostly CPU processing time. Low ram wont slow down your phone, it will simply stop you from loading anything more.

thank's guys, i am a little smarter now than i was before . i promise i will make a donation soon coz' you are the best there is...

Benefit from 128 MB upgrade - Speed?

I am thinking to tweak my Universal to 128 MB, but what exactly is the benefit?
I think the speed will go up because the os can put files in the ram but it is really noticeable?
Thanks

Apps like Opera and Navigon will greatly profit from more RAM as they eat our measly 30 MB free RAM (best case) alive. You might see more speed on previously slow tasks like opening the Windows folder if the ROMs cache settings has been tweaked to suit the available RAM. But other than that programs just give you a message once you run out of memory and as there is no page file no slowdown occurs.

diamond main storage problems...

iv seen many ROMS show free storage as 50 mb but what baffles me is what they shows as how much main memory really is... example many newer builds shows as max main memory as + - 90 mb or close thus the titanium 6.5 endup using half of that and remaini9ng 40 50 mb is not enough if i then install tf3d 2.1 tachi and other stuff say R33 theme. and ill endup at 2 to 4 mb only and annoying warnings.
now if i see many builds thats includs tf3d 2.1 still ends up at 40 50 mb free how come? when it still shows 90 mb or so main memory.
but then few like benko's, boggysoft's, Don Salary's ROM shows 130 mb main memory storage and then it uses half of it giving more then half of that free. benko's even 100+ with tf3d.
why im asking many good newer builds like 23071 when used from many cookers, shows less then 100 mb max storage to start from and all are clean titaniums only, thes doesnt work for my uses.

i got tired about thinking about the main storage space, so i installed the clean version of http://forum.xda-developers.com/showthread.php?t=553844.
At the moment i have 135mb free storage space on the main storage.

u didnt get my point... thats exactly what im asking why this benko's ROM have so much space left when it has tf3d 2.1 + a lot of stuff, and why a clean titanium only ROM doesnt?

Where is my memory?

My AT&T Tilt2, using Energy Rom now:
on the Hardware information tab, I see RAM Size: 288 MB， Flash Size 512 MB，and Storage Size 241.6 MB。
But, on the Memery/Main tab: Storage Total is 241.6 MB, and Program Total is 183.47 MB。
I think the RAM is used for Program, while the flash mem is for Storage. Then, my question is where the other memory is?

If you have a stock rom, the at&t bloatware takes up the majority of it.
I flash mine with a custom rom, which rids the phone of the bloat/crapware.
I also flash to a no manila version, which takes out the touchflo3d graphics, which I don't use, and that gives you more ram/memory/storage.

Those Storage and Program Totals are more-or-less the same with most ROMS....not that I've tried most ROMs but a sampling.
For example, on my Valky ROM the Storage Total is 271 MB and the Program Total is 181 MB.

I am not using the stock ROM now. Originally I thought it was the Stock ROM that has some function like ghost, which enables the OS to restore completely. Obviously I was wrong.

You are right. But where is the missing memery? What are they used for?

What is it you think is missing?
The Hardware Information tab also list OS Program Memory under RAM and OS Memory under Flash size. The Memory Main tab doesn't list these totals, but they are in use by the OS.

The 288MB of RAM does indeed exist in your device, but the way the OS uses it makes much less of it appear in the Memory dialogue, as much of the RAM is not usable for programs (so there's no point in displaying it). 32MB of the 288MB is part of the baseband, and cannot actually be used for programs. Anywhere from around 8MB to 24MB of RAM is part of the Page Pool, which is somewhat like a HDD memory cache in Windows. In addition, some RAM is used for the framebuffer, the radio stack, and the XIP (OS kernel), among many other things.
There is an article on MSDN, written by the Windows Mobile team, which goes into slightly more detail about how RAM is actually used on a Windows Mobile device. But the short answer is that Windows Mobile uses a lot of RAM for critical, low-level functions which have RAM reserved for them. Windows Mobile decides it shouldn't display RAM that will never be used for running userspace applications, so the RAM displayed on the Memory applet is often much less than the actual hardware RAM present in the device.

Thanks much for the explanation and the link to more explanation. I knew I'd read months ago...somewhere...that there was a good, non-mysterious explanation, but didn't spend the time to find it.

[Q] What depends on how much RAM your device have free?

Hi,
i have used sevaral ROM, with difrent storage mods and all different roms have difrent size of free RAM - (after app killing), all betwen 200 - 260, now i use a data++ rom and i have only ~200ram avilable and 95% of apps are on SDcard, my prewios rom was a D2SD and it had ~250 RAM free after killing.
From what depends on how much free RAM your ROM have?

It depends on the apps and services running in the background.

Sure, but in both roms i killed all runig apps with task killer and end up proces under Running services, i only left (obex, touch input and killer service), but the result was different in different roms.. (250 vs 200 free), whats the reason for the difference?

How much space did you have on both ROMS after the first initial boot?
By their nature, Data++ ROMS require modifying the system partition to allow for more internal memory (so you are relatively limited in how much you can assign- upto about 330MB using the Oxygen Hboot table), whereas DataSD ROM's available space is largely determined by how much space you allocate on your SD card to it (anything upto 1.5GB with some ROMs).
Generally you will have less internal memory available on a Data++ ROM than a Data2SD. But on the Data++, performance is far better than D2SD.

I dont know the space after the first boot, but the internal memory in the data++ rom is larger because of the costom MTD, than the stock MTD.
But i still dont understand what depends on the RAM mamery size avilable after killing and stooped process?
For exemple:
AraxTsenseHD had ~250 free memory after killing
RCMIX HD data ++ has ~200 free memory a. k.
LeDroid had about ~200 free and also RCMX S had ~200 free
Depends the free ram on the setings of each ROM or what makes the difference?

It depends on the services running and the ram needed by the system.
