Is it possible, to have much more RAM available in Roms

A year of 7 ago I owned an IPAQ 3780. On that device you could change the amount of memory and storage. More memory and less storage or otherwise.
According to the HTC website, the HTC diamond has:
ROM: 256 MB
RAM: 192 MB DDR SDRAM
Internal storage: 4 GB
Most roms with TF3D enabled have around 60MB ram left after booting.
Still it makes me wonder why we can't change that amount by making the internal storage smaller and add it to the memory. The device comes with a 4GB internal storage, so what is the point of having a large 'standard' storage. It is not that difficult to move pointers to 'my documents' to 'internal storage\my documents' etc.
But asking this, i think Rom builders already know there is a reason why the RAM can't be enlarged.
Please enlight me with the answer or start discussing how to build such a rom.

That's impossible, absolute different technologies in RAM and storage.. And btw, 64MB of RAM is used for video acceleration, and 60MB goes to Windows Mobile..

In your old Ipaq storage and memory were the same. When the battery was empty all your data was lost. Only the os was kept in the rom. Since Windows Mobile 5 all your saved data is in the rom - and cannot be lost when the battery is empty.
so you can not enlarge the rom by decreasing the ram - its completely different hardware.

Yep, those were the days of WM3 where that was an option to the end user. Even if such an option existed today, how many would actually subtracted the storage for more ram? Well, every user is different. The way I use Ram vs. Rom on this device is basically straight down the middle.
To each is own! The trick here is to work with what we have. I think we aren't doing to bad at all!

Oke, that answers it.
Though 64MB for video acceleration is a huge buffer for this 640*480 pixels screen. Stealing memory there?

More ram?

Is there a app or a way to partition the internal memory to use as system ram? I use Swapper for root but it just doesn't work as well as I'd like. I know they loomed into a while back and concluded that the speed of the memory wouldn't work for processing ram. Anyone know?

Scientifically impossible. However, there are apps which use memory "like" ram, to enhance performance(they are not really that much of improvement) but I believe 1GB is enough for doing anything possible on a phone.

Using a lot of RAM... for some reason?

Ok so I was running an app to check on CPU speeds (unrelated research) when I noticed that this same app was saying I only had 340mb of RAM free...
This seemed a bit strange, considering this tablet has 3GB of RAM on board, and I'm not really running anything at the moment.
I went into the storage setting page, and looked at running processes, and it says that I am using 2.5GB of my RAM.
but... if I add up all the ram usage on all the running processes, it only adds up to about 500mb....
So what is using up the other 2gb?
If anyone has any suggestions, it'd be nice, as at the moment it seems I only have 1gb of usable RAM in this device...
EDIT:
Nevermind, I think I solved it... sort of. I found that the ram clearing button is in a different place than I remember, and I have managed to clear out some more space... though even after a full reset 1.5gb of ram is immediately being used. Seems a lot.
Though this is a stock rom etc so I suspect thats normal.

You probably aren't using all 2.5GB for actual running programs.
Windows 7 does a great job of managing money. If it has any unused memory it will hold often used programs or data in memory in case it's needed. If a running program needs that memory it's quickly shifted. Otherwise when you reopen that program you recently closed, it may load quickly from memory rather than from the drive. I suspect Android does things similar.
Modern systems programmers consider "free" memory to be wasted, so they put it to the best use they can anticipate. That gives you the benefit of all memory as often as possible. If they only allowed the memory to be used for what's needed right now, your Note would only have about 1 GB memory, and would be considerably slower.
It's a little like having the cook wash your car while waiting three hours for the turkey to cook. You get both the turkey and the car wash.

I'm guessing you mean android, not windows 7
Though I imagine both do the same thing lol

I used Windows 7 as an example because I know how it works. Like you, I imagine Android 4.3 does the same thing.

I was wondering about this as well. On my Note 2, when I clean the ram, it will go to 480-500 / 1.75g on this tab, ext I could get is 1.33/2.75.......
I went through and turned off a lot of the apps, it helped free up a little bit.
Does anyone have a list of the apps that are safe to turn off?

I have LTE version with Snapdragon and when I start the tablet, it uses about 890MB of 2,35GB available (yes, it has 3GB RAM, but graphic processor uses some of this RAM)... When it loads all apps to RAM (about 50 of them, we know android do this) and I start few apps(FB, Gmail, Chrome, Hangouts for example), I still use only about 1,3GB of RAM... So almost 1GB is still free

In Android having too much free ram is not a good thing. Let your apps use it, you don't have to worry about not having enough ram, OS manages it well for you.

Android is a mobile OS which means that it can backup and restore not needed apps if necessary and the 3GB are only the runtime memory beside this it can use the whole internal memory for "running" apps. So long Android got enough memory it holds all apps in memory which speed up the whole device. Therefore it is positive that the Note use his whole 3GB memory and don't think that killing apps or free memory will be a good idea. It will slow your device and produce lags.

They are both right. Android is based on linux. Linux uses ram very effectively to cache apps and data to speed up your system. When something needs ram it removes a different app or data from the ram to keep moving. It works totally different from Windows. Check out this article.

Every day since Android came out someone asks this question somewhere... Is Google offline?

If you want to change how your ram is managed, and you have root, you can use the v6 supercharger or a simple minfree setting app. V6 is in the developer section of the general android forum on this site. I've found that m ram fills up from cached apps. V6 will let you auto clear however often you want.

How to increase your internal Ram By Swaping

HEY XDA DEVELOPERS
today my thread is about increasing ram
Your phone’s RAM is a very essential component which plays a vital role in the speed and the performance. if you have more RAM, it means the processor have more storage capacity to process more and more temporary functioning files, and hence it can freely work which ensures the device is fast enough. But if your RAM is low, the processing power of the device is affected. Like if you have a low RAM< you won’t be able to play high end games on your Android Smartphone, or even ti might lag while doing simple tasks such as seeing a video, typing a text etc. So if you are suffering from low RAM, and want to get rid, you are at the right place. By reading this post you will be able to know how could I increase the RAM
Things before increasing RAM ::laugh:
Before you actually start out to increase the RAM of your smartphone there are a couple of things you need to know. In this post we will use a app to increase the RAM and this app requires root access to your phone. So make sure you root your phone before starting out. Also note that there are some issues with this app as roof uses a swap file that will be made on your SD card and hence used as ram but as some of the Android smartphones so not support swap file so this app won’t be functional in that case, so before starting out make sure your device supports swap file. You can check the device compatibility with swap file using this app. If it says it fits support follow the steps in the post to increase the RAM of your Android smartphone otherwise you can also increase the RAM of your smartphone using the link below and the link below will also work for unrooted users so in case you are unwilling to root your device to increase RAM you can also follow the below tutorial.
ROEHSOFT RAM EXPANDER :
This RAM expander app is one of the best app available in the play store which allows you to easily increase the RAM of your Android smartphone. So let’s begin with the process to increase RAM using ROEHSOFT RAM EXPANDER. Have a look at some of the features of this app to increase RAM of your device.
1 Swap memory file upto 4 GB ( In simple words it can increase ram by 4 GB depending on your device and memory card too)
2 Widget for PNP swap
3 Detailed analysis of your memory and details about it
4 Swappiness kernel parameter already set.
5 Very easy to use and create swap file and really simple interface
6 It will work with most of the Android devices.
Download from attached files
Pre-requisites :
Here is a list of things we will need before starting the process to increase RAM.
A rooted android phone, so if you haven’t yet rooted your phone first root your device as this method only works with root access to your device.
ROEHSOFT RAM EXPANDER app, you can get this app from play store but you need to know that this is not a free app. (though you can number of apk files for this app but most of them won’t work due to license issues but you can try them, if they worked it will be your luck ).
An external memory SD card installed on your phone.
How to Use ROEHSOFT RAM Expander :
So file the steps below to increase the RAM of your Android smartphone now.
Install the app on your device on which you wish to increase RAM
Now after installing the app choose your default language.
Now to increase RAM create a SWAP file by clicking on the SWAP Active and enabling it
After the process is finished just click on the grey colored box and activate the swap file created.
Congratulations you have successfully increased the RAM of your Android smartphone.
This increased ram will not show in the task manager but you can feel the change with the overall performance of the device which seems to be boost up. If you already have a decent ram them got might need to run some very heavy game to know the difference in performance. So I hope this post helped you in increasing the RAM of your Android smartphone.

Can you lower the ram usage?

Hi there,
I have the ZF2 with 4GB of ram. After a couple of days of usage, it seems impossible to lower the ram usage below 1.8GB even when I clear the cache of all apps.
However, when I restart the device, my ram usage is below 1GB.
I have uninstall or disabled every app I could without rooting. & I don't want to root now.
Nonetheless, I would like to keep the ram usage of my device as low as possible (2GB of ram use seems a lot to me, especially when I have one or two apps open)
Did you find a tricks or ways to keep 2gb or more ram free at all time ?
Thank you.

Simply, there is no clear way and those numbers are normal. The best memory management is with native linux, not yet available on zenfone 2.

What's the point of always having 2gb of free ram? RAM is completely useless if you aren't using it.

It's not a question of useful or useless. It's a question of is it possible and if yes, how.

Yes, keep the phone in deep sleep with all apps closed and disable everything in autostart , better yet, you can just power off the device
p.s: not even custom roms will run that low, I had cm12.1 with lg g3 3gb ram, I disabled basically everything and phone will still boot with at max 2gb free ram, maybe 2.2gb if you start killing launcher and sytem apps lol
4Gb ram with 2.2-3Gb free Ram is plenty for a cellphone. Its even plenty for a desktop unless you run hard core 3d games like crysis.
The lowest I have seen is 150Mb/1Gb usage with Nexus 7 v1 tablet yet it was hell slow. Note that the more Ram you have, the more the system will use it and cache in it. This will increase apps loading speed since they are directly loaded from Ram vs local storage.
I would love to have an app that lets you select what to cache in Ram, e.g. large high-resolution PDFs that take forever to open and load :crying: I have 300-800Mb PDFs that will take 1 min just to open.

Indeed, an option to decide what to cache would be great.
Can we expect less usage and caching with the 5.1 update or with a custom Rom?
