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.
Does the 768 RAM on the MyTouch 4G allow installing more apps or is the memory reserved for apps/data the same as for a 512 device?
Thanks.
I think you are confusing the memory used for storage (1gb available internally) with the memory used for running apps (768mb).
You have 768mb of system memory (for running apps). 1gb of internal memory for apps/storage along with 8gb on the removable SD card.
What are you talking about man?
RAM = random access memory.
ROM = Read only memory.
Ram is what used to allocate the programs/app that is already installed on ROM, so it can run on the phone. In simple ROM is where you install it and to run the program when you load it then its allocated in RAM, I hope it make sense to you.
I've currently got an Acer Liquid E which has 512 MB RAM but I need an AWS phone now.
The phone has 512 MB RAM but only part of that is allocated for storing apps and their data. I believe after a clean wipe only around 70 MB is available for apps (I could be wrong about that number). I believe the rest of the RAM is reserved for the OS and various caches. Even though many apps can be moved to the SD card, there always remains part of the app taking up memory in RAM so if you install too many apps you'll eventually run out of space and things get ugly.
So my question is whether the larger amount of RAM (an extra 256MB) is (at least partially) available for a larger amount of app space, or whether the amount of space available for apps is the same as on a 512MB device, with the additional 256MB being used only by the OS...
I'm sure I've got some of the details wrong, but still the basic question: can the MyTouch 4G have more apps installed before going wonky than say a Samsung Vibrant?
Thanks!
No wonder you got confused I just looked up the spec for Acer Liquid E. It has 512MB ram and rom. Now you are saying that you installed alot of apps and its becoming sluggish? In that case disable some of the service and close some apps you don't use. Normally you won't have 512MB or the actual ram in any device as OS itself and other things use some memory some even used for accelerated graphic depending on the phone.
What you should look for is first remove all the boltware and run the phone barebone without running many things then you can see how much actual memory is available to you to run other service/apps. Also you can save the app as in installing in SD but that has nothing to do with the RAM which is just saving in SD and not in NAND. But when you run the app it will still have to be allocated on RAM thus enabling you to use it.
On my system the RAM appears to be partitioned into /system, /data, and /cache. It seems the /data partition is what's available for use by apps. When this gets low (around 20 MB or so) performance is seriously affected and some apps don't even work right. On my system there is 200MB available for data. I assume it's similar on other devices with 512 MB RAM.
One way to check is install the free app "App 2 SD Free" and on the "On phone" tab at the bottom it will give you total and available memory. (I'm sure there are lots of other ways to check, but it's one app I've got installed that has this info. Here's a link: whoop's it won't let me post a link...)
Anyway, what I'm trying to find out is if there's more available memory on the MyTouch 4G. If someone with this phone could run this app let me know what the "total" memory "On Phone" is I'd appreciate it!
Thanks!

You have your definitions messed up:
You are talking about ROM (read only memory) which is like hard drive in your computer. MT4G has 2gb of memory with about 1gb available to end user. SD card can be used to supplement ROM, if app developers enable it (most do) so you have the potential to have up to 17gb of storage space for apps.
RAM (random access memory) is what used to actually run those apps (i.e ability to multitask) and so far this phone has more RAM then any other phone on the market (768MB).
In short: you have roughly 5 times more available memory for apps then on old phone and that does not even include SD card.
Does that help?
Ignore this post: read the one below.
OK, I think I've been confused because the Acer has 512 MB RAM and ROM. So as I understand it now, there's some amount of ROM on the phone that is available to install apps and separate from this is the RAM used to run the apps. I'm guessing the amount of RAM taken up by apps depends on the apps and services currently running, not on the total installed in the ROM?
So having more ROM will let you install more apps but having more RAM will be better for multitasking and speed since more apps can reside in RAM before being swapped out?
From what I've picked up on this thread and Google:
MyTouch 4G: 758 MB RAM, 1 GB user ROM
Vibrant: 512 MB RAM, 2 GB user ROM
Liquid E: 512 MB RAM, 200 MB user ROM
The Vibrant can have more apps installed but the MyTouch should be better at multitasking (and 1 GB space for apps seems like plenty). Either phone should be far better than the Liquid which is seriously constrained by the small ROM.
Is this generally correct? If so, I'm definitely leaning towards the MyTouch 4G.
thanks!
Yes thats some what correct. In this case you might want to go with MT4G due to superior hardware capabilities. Vibrant has issues and you will need lagfix before you can work it fully but on MT4G is good to go out of the box if you are android normal user.
If you look at quadrant benchmarks for Vibrant against MT4G. The MSM8255 (2nd gen snapdragon) CPU and Adreno 205 GPU blows away the Hummingbird CPU and SGX 540 GPU. ATM MT4G and DHD is the fastest android device in market. With MT4G you have elegant balance in ROM/RAM for nice performance. BTW MT4G has 4GB ROM but 1GB user accessible.
Thanks. I'm going to try and get the MT4G.
Hello,
I recently bought a Samsung Galaxy SII and I have a question about ram usage.
When I boot up my Galaxy and open task manager it says I have about 200 - 210 ram in use but after a while I see it uses 260- 290 mb ram.I kill all apps and clean ram with task manager ( and task killer pro ) but I never get back to the 200 mb. It's not bothering me too much but I would like to know why this happens and how to possibly fix this
Thanks in advance Cédric
Your system apps (which would be very dangerous if you killed them) are using up the ram. You could possibly fix this by checking out this thread and doing what is says: http://forum.xda-developers.com/showthread.php?t=1111145.
Hello Epson,
after booting, I get nearly the same values, like you: 297 MB used / 837 MB free / 0 active applications
With regards, Michael
Hi I have galaxy y and I read it's phone specification online before buying it. the online specification all says that it has 512mb of ram. But after I bought the phone, task manager shows that the phone only contain two hundred something of total memory.so where is the remaining gone? Is there any way to gain them? Like uninstalling what from system? I have rooted my phone but I don't want use swap as well. I want the original ram memory to the maximum available. Any help would be appreciated.
It's used by all those system apps running in the background. Like launcher, phone, messages and stuff. 200mb is a decent amount of RAM (considering it has oly 512 mb). If u want more ram try using a light weight launcher, a custom rom helps too (as in stock rom they put a lot of unwanted stuff into it).
I own a samsung galaxy tab 2(GT p3100), which initially had 4.0.4 ICS with 687 MB RAM(but specified as 1 GB RAM, as some developers claim that it is being reserved for system). I updated my firmware to 4.1.2 and now it showed me 770 MB RAM. later i rooted my device and installed the latest CM(cyanogenmod) 10.1 (jelly bean 4.2). To my surprise this rom which has less bloatware and is smoother, it showed me 691 MB RAM, less than 770 MB as displayed by the STOCK jelly bean OS.
i would like to ask, which OS(custom/stock) displays the MAX RAM for GALAXY TAB 2 7.0(P3100)???????
as i don't ve enough internet downloading capacity(limited downloads), i can't just go on downloading all the firmwares and keep flashing everytime, SO EXPERIENCED USERS, PLEASE SUGGEST.
for more info(for my knowledge), do please tell this also--------->tab 2(my device specifies 1 GB RAM and the same does galaxy s2, but why with ICS(4.0.4) installed both the devices show different MB RAM. tab2 shows around 680 MB wheras S2 shows around 880 MB, wheras HTC one X shows 1 GB.
why is this so????? i know some developers claim that this RAM is being consumed by system or reserved for system, but why is it different for different devices, when the OS is the same?????
again if you claim that it is reserved by the android system, then WHY DO , WITH NO APPS INSTALLED TOO, I SEE AROUND 300-400 MB RAM BEING USED(300 MB WHEN I DNT USE ANY WIDGETS AND ALL, AND I STOP ALL THE PROCESSES, BY CLICKING FORCE STOP ON ALL APPS LIKE GMAIL AND EVERYTHING EXCEPT ANDROID SYSTEM AND PHONE AND SOME NECESSARY RED MARKED APPS IN THE DEFAULT TASK MANAGER).
if android process is being displayed here with this 770 MB ram, then where has the 230 MB ram gone------------>do you mean the android process consumes the hidden RAM and also a part of this RAM too???????------------------>this sounds too unpleasant, when htc one x displays all the specified RAM but my tab fails.
really disapponting
You are getting too excited about available RAM. The OS system manages available RAM so each different ROM will use it a little more or less.
The amount of free RAM has nothing to do with how many apps are stored, ONly how many apps are RUNNING. Android system efficiently manages RAM and tries to keep it about 80% full all the time. So called Bloatware (one mans bloat is another mans useful app) has nothing to do with speed , they do nothing if you don't run them.
The system RAM usage contained OS buffers, temp storage and system routines that are always loaded for speed.
1GB is a ton of RAM for android.
You do not have a RAM issue.
You can run out of SD storage space for downloaded apps if you store too many. But you have several GBs of storage so that's hard unless you are a real pack rat.

Right Sir,
well, regarding storage i dont ve any issue as some data like pics and vids can be kept in ext storage card too,but i also wanted to know which ROM provides user with more RAM, so that it will be good for multitasking or if i play high end games like NFS MW

The amount of difference between one kernel and another (which is what really matters here) isn't large enough to make any real difference in the performance of any application. The available RAM after the kernel grabs its stuff varies around 10% from one kernel to the next.
If you want to make a performance impact, make sure you minimize the number of running applications that compete for the available RAM. However, that won't make much difference as Android is very aggressive about grabbing memory back from idle applications.
Basically, you're obsessing over something that in the end will make no difference in how your tablet runs.

Irrelevant. Android will clear apps from RAM if it's needed by an app with high memory usage. This isn't windows

well, if this is the thing, and android can kill apps automatically then why do some people prefer custom ROMs like CM or AOKP.
even for installing custom ROMs they need to root their tab/phone, and if they root and want to get rid of so called bloatwares and make their OS lightweight, they can uninstall it using root uninstaller(available for free in google play)....
but why do they prefer custom ROMS?????

More features generally. Some roms will manage the memory better than others, ie at what point it starts to kill apps to free RAM(although this can be adjusted in any rom using rom toolbox or a similar app). many custom roms include a theme engine allowing more customiza. They may make better use of resources to decrease battery usage or because it has better cpu governors which will increase performance. They may flash a custom roms because it's kernel includes modules that aren't in the stock Kernel. There are many reasons besides RAM usage, since as you say you can root and remove bloatware and change memory handling(called minfree or oomut of memory)
