[Q] Change graphics memory size

As I previously read, out of the 512 MB of our O2X's, some 128-140 MB are reserved for the Tegra chip-set, and the rest of 380 MB are available to Android and applications.
With Froyo, there were usually 180-200 MB of memory free after booting/killing all apps, and like 90-130 MB free after normal usage. I'm not sure, but if I remember correctly, in the running apps screen, the sum of the used/available memory summed up to about the previous stated 380 MB.
After applying the GB update, after booting/killing all apps there are only 140 MB free and about 60 MB after some usage. If I go to Manage Apps -> Running apps, the sum of the used and available memory is around 310-320.
My question is: why is there less memory available in GB? Has LG increased the graphics memory from 128 MB to 192 MB? If yes, is it possible to change this allocation? Or is there a ROM that uses less graphics memory?
Maybe GB reports available memory differently, but it's definitely noticeable that there's less RAM available. If switching from browser to another app, with Froyo the page loaded was kept in memory, however with GB the page always has to be reloaded even if the switch lasted like 20-30 seconds.
Edit: I'd like to use less graphics memory and have more RAM so my apps run faster.

No the Vram is the same. The phone still has 380 mb ram to use for the OS and apps. Also free ram is wasted ram since apps are not cached so they will not launch faster.

Not completely true. Android kills automatically unneeded processes, that's true, but sometimes it happens that an app remains in background and uses the 100% of the CPU, so i use the task killers to terminate it.

Try Super charger, very efficient and not as resources consuming than apps. Search the dedicated thread.
And I don't think there is a way to free graphical memory. I don't think it's software driven but physical...
The only thing that had been made is to free the reserved memory for OTA LG service, that leaves you some more memory, but only available in some roms.

Its possible to give the GPU less memory, different defs have done it (i.e benee). But as far as i know most of them removed that tweak since it was causing alot of bugs.
And yes, free ram are most likely wasted ram.

If ya want to change vram look at this: https://raw.github.com/gist/1170959/73e5f41b1ad8b3bb65c8bd22d422a4fd877204a3/CarveoutMemory
It contains a little info about the things you need to change. Some skills required though

Hi kiljacken !
I remember that you've made some times ago a kernel with 64mb more of ram...
Also for the stock rom...
butI can't find it anymore...
Any help?

Thanks for the replies guys!
It seems like if possible, it's very complicated to change the video memory allocation, so I'll leave it like that.

hey all!
i have question like that! im working on electronic factory and have no problems with solder out and in BGA chips even the smallest ones! now the question! if i will solder out the ram chip and solder back in 1GB ram chip of the same tipe and company(i have acces to all the part available on the market)?

I'm very unsure. I am sure though, that both kernel and boot image changes would be needed to run with the added memory

i think it's impposible to change the graphic memory size, maybe RAM hack? if you want to free RAM just use supercharger, i already used that and my free ram about 117-130 MB

It's completely possible, it's something that's controlled by the kernel.

Such kernels already were in the spring which reduced video memory by 64 Mb

so if I'm understanding correct if i will solder in new memory chip all i will need is to find how to change the ram value from 372 to 872?

I suppose if LG's programmers were careful enough not to hard-code any values, the phone should detect the memory like a computer detects new RAM. However ROMs which target multiple devices with different RAM, like CM, shouldn't have such issues...

I would LOVE 1GB ram! What would such ram cost?

Guys, RAM amounts are hardcoded into the kernel, so a custom kernel would be needed to use the ram. IF it's even possible to use such amounts of RAM. There migth be limitations in the bootloader, which will cause problems, but kernel changes should be enough. If you try it on your device I would be glad to provide a kernel that supports that amount of RAM, but I don't think it's doable. AFAIK the RAM is tightly packed in the device with many other components. It might even be built into the SoC making it impossible to change. But IDK, feel free to try what you want, but remember it's your device that gets destroyed if something goes wrong.

Do it OP!

How RAM are allocated in Droid 3

I know there are 512MB RAM in Droid 3, in addition to 16G internal storage. However, I don't know what go to the RAM. Are the bloatware going to take part of it, or they are simply stored in the 16G internal storage? What about the OS?
Hope I can get some insights on this. Thanks.

i dont understand. your post sounds as if you think programs are installed on the RAM. they arent. RAM is random access memory, programs arent stored on here, they use RAM to run commands. The 16gb is what your programs will be installed to

Not all 512MB will show as total memory its around 370-380 I think that is because the graphics use some of the RAM. Some bloatware will preload into the RAM as well as some of your apps. But when RAM is needed for the program you are currently running lower priority apps preloaded will close. So even if you see bloatware running in the background it cannot take away RAM when you need it.
The 16GB is flash memory for installing programs, etc. Android is not like older versions of Windows Mobile where apps were installed directly to the RAM so the 16GB of memory and the 512MB of RAM are for two totally different tasks.

Thank you.
After I posted the question, I did some research on google. Basically your replies are pretty in line with what other say. The 512MB RAM is used when running program, and OS too. Motorola says there is a 1.5 secured storage space in the phone. I guess that is where the app are stored physically. When being run, the app will be loaded into RAM.
Yes, the sum of used RAM and free is less than 512MB. I guess the difference goes to the OS and graphics. That's what I learn after posting the question. If there is anything you think might help understand these terms, please share.
Thanks for all the feedbacks.

Well, you can use a swap partition. CM7+ also has ram compression.

For me Ramexpander say is not compatible with Ace.

I heard swapping partition from sd card to increase the ram, sd card might get damaged!!, is it true?

Reduces SD Life so yes.
Sent from my iPhone

but i guess you will change your sd card before it gets damaged so much, that you will notice.
i only had this once on a USB pendrive. it loses data since some weeks ago. but its about 8 years old.
lets say that todays SD cards have better lifetime than years old USB sticks. lets also say that you use your sd card more often than i used this stick (backups later car-radio). so we can say your SD card might have a bit less lifetime. lets say 6 years. in 6 years you will (most likely) have a new phone, sd cards are "oldies" and if not, 1TB cards are state-of-the-art.
so....yes you loose lifetime but i dont think you will use it till it "dies"

It really depends on use. When I swapped i ate through my sdcard in less than 6 months.. so there you go. Keeping low swappinness will increase sd card life, but it does depend on use.

increasing ram by swapping sd card is effective to what extent...can any body tell me....does it bridge the gap of our low ram...

That why the requirement need class 10 SDcard

You can use CM7 that uses less RAM!.. I just went from CM10 to CM7 and it really is an improvement for ACE as it uses a bit less RAM and that is noticeable.

thanx but no cm7

there are quite a few apps for increasing the ram like ramexpander and swapper...
but before using these apps remember that the read and write speed of sd card(which is secondary storage) is vey less as compared to that of the internal ram.. and probably thats why ram is very expensive as compared to sd card...
so if you use these apps may take a bit longer to start and even the best of sd cards i.e. the class 10 one won't last longer than 6 months...

Increasing ram
Hi i install ram manager pro apk on gts5830i then i create a swap file 128mb using this apk, then on sd card i see swap file img does it mean my phone ram increased.... i didn't install any kernel for it... plz does tell me if it increase ram or not...

I tried something on a other phone from my neighbor. is a huawei with same specs than the galaxy ace..
I moved apps to SD card with link2SD and created a Swap file in the internal storage.
The internal storage is much faster than the SD card and much better for swap file.

What is RAM
Random Access Memory (RAM) is temporary data storage that the CPU uses during calculations. The more RAM a device has, the more calculated results the CPU can store - which means less time the CPU has to do the same thing over and over again. In other words, the CPU can check RAM to see if it has already made a particular calculation in the recent past. If it has, it can use the pre-computed results instead of wasting processing time recomputing the same calculation. In short, more RAM means a more efficient (and faster) device.
SWAP
What is SWAP
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

[Q] is there really 2 gb of memory in this phone?

Hi,
I'm a bit surprised that if I add free memory and used memory from the Settings app the total is about 1.7 gb. Ain't we supposed to get 2gb? I hope sony didn't do the hdd trick (see wikipedia page on Kibibyte, I cannot post link as a junior member) and even so 2000000/1048576 = 1.907 ... where's my ram?

Under CPU-Z that show : 1.732Mb.

yes it does but I thought it will be included in the "used memory"... if the OS takes 300 mb that's ok but why I only got 900 mb free when I kill all apps? I used to have a nexus 4 and with the same amount of memory on chip there was a *LOT* more available in the settings menu.

That 900MB figure is about the same I normally have free. Various apps and services take up about 800MB on my phone, which seems excessive but I've turned off all background stuff that I can (some Google and Xperia services just won't go away, however). The only good news is that Android will free up memory if it's needed so that 900MB is not a finite figure (at least that's what I assume).

Hmm. I generally have no more than about 300 mb free memory at any given moment. Even just a few minutes after reboot. No weird apps or excessive widgets. Do you guys really have 900 mb free? You can check your memory on the fly using Cool Tool from Google Play.

The Z3C has 2GB of RAM, don't worry. What you are missing is used by shared graphics memory. BTW: This is exactly the reason why the Z3 has 3GB of memory (instead of 2GB) for its screen resolution is full HD opposed to "only" HD on the Z3C.
Anyhow, is it really necessary to start another thread on the same topic if there already is one?

I have never had any doubts about the two gigs. But how much free memory do you have on your Z3C after a reboot and after a few hours of typical usage? My other phones with this much ram have generally had a lot more memory available at any given moment. Not that *free* memory is of any particular use in android, but I'm still curious to see whether your Z3C's are the same.

When I boot up the phone and immediatly check it shows some 800MB of free memory. About 500 to 600MB after a couple of days, fluctuating though. However, don't think these numbers have any meaning for Android keeps as much in memory as possible in order to increase responsiveness. It also depends on the Apps installed and the bloat disabled/blocked. Further, comparing it to other phones you had earlier might also be misleading since the version of Android could be a different one, hence comparing apples to apples would just not be possible.

More RAM?

Does anyone knows how to swap sd card for expand ram to 4GB with stock rom or any rom. Is it possible on z3 compact. Samsung's phones can do this. Can we add more ram with storage on Z3Compact ?

bookworth is right, the difference in speed between the internal memory and the sd card with make it go slower not faster.
You could use Kernel Audituor to increase the Z-RAM size, this will give you more page file on internal memory, but I doubt very much you'll see any difference in performance. Unless you're getting 'out of memory' errors, I'd leave it alone.
