[Q] How to recover lost RAM after removing ZRAM - Optimus One, P500, V General

Hi all.
How much is the actually Total RAM on Optimus one.? I have 74 used and 323 free . Totally 397
I remember having more than 410 MB Free Ram before flashing Franco's zram. As the latest kernel doesn't require zram. I removed it using the remove-zram.zip . Expecting to get Back the lost ram. But I still don't get more than 397 . Please help to get back all the ram and can any body please post their running apps screen shot
..to compare it with mine

You're lucky dr.notor isn't here or he would have come up with some sarcastic reply to this question.
Having 13 MB of ram less than normal is no big deal. The system uses the difference (512-397) for its use. And the system usage keeps varying, so you will never have a constant amount of free ram available. I seriously doubt zram is the problem. Also, our phone has tons of ram so stop obsessing over it. I'm quoting a paragraph from an article on lifehacker.com:
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

Total ram is always 418mb or a bit higher regardless of zram

Quick RAM question

Quick question here, something that's puzzling me.
It might be because I'm just totally wrong, but our X10's have 384MB RAM correct?
Now, I thought I had heard before that Android 1.6 limited RAM to 256MB. Since the update, shouldn't I have around 100+ more free RAM than I had before, due to 2.1 allowing for the full 384?
For example, I would have about 110mb free at most times in 1.6, and with the same apps/widgets/etc running on 2.1, should I have around 210mb?
Answers appreciated
(P.S. anyone know why search never works for me on these forums???)
I'm not quite sure, but I remeber reading that it uses 256 mb of ram memory and the remaining is for the graphics.
I was wondering about that. Quadrant shows I have 280MB plus 128MB 'inactive'.

That'd make sense, never really thought of that.
I'll have to read into it a bit more, I'm pretty new to Android so some of the more technical stuff is still unknown to me

[Q] Real RAM size

Hello, as we know, Galaxy S1 was advertised with 512MB ram, but in real there was only ~340MB of usable RAM! So i want to ask, how much ram is usable for applications and how much is free after fresh boot? Can someone check this? You can see this informations in task manager.
I think its about 800-850 RAM.
The original SGS had 512mb of ram as advertised. For some reason people assume that their phone behaves different than their computer. The operating system and everything like that needs to use the ram as well.
AS stated though I understand the SGS2 to have approximately 850MB of ram free after running the OS etc.
If I continually hit advanced task killer it will give me about 445MB free. In the standard task manager it says /833MB.
I don't really think this is all too relevant. You will never have anywhere near the maximum amount available just as you won't in a modern PC either and with phone OS's getting more power hungry and complex this is unlikely to change.
If the amount of ram bothers you check the video of the guy doing heavy multitasking on the phone and that will clear your mind.

Thank you for usefull information. I'm just interested in real numbers, because HTC phones have all advertised ram available to system, instead of samsung, which is cheating about this. Yes the OS is using ram... but from 833MB, not from 1gig. How can system use ram which is not visible to system? Android is linux, you can easily see how much ram is available and usable for system... it's 833 not 1gig. I believe that there is 1GB ram chip, but some memory is dedicated to other components. However 833 MB is really enough for mobile phone.

It did have 512MB of ram in hardware, but a pretty big part of the 512mb was actually dedicated video memory for 3d and movies. The Galaxy Tab 7" which was advertised with 512MB actually had ~600MB of ram in hardware, with extra ram outside the 512MB being for the dedicated video.
With the SGS2 it seems to be as the original SGS with dedicated video ram being taken out of the 1GB. It's easy enough to check by looking at the kernel config files. (And you can even tweak the numbers a bit to get a bit more free ram, as was done in the SGS)
Hope we're not heading down the old line of trying to run with loads of free RAM... I'm of the philosophy that if you have the RAM available, you should use it, rather than have to load things up from storage due to removing it to make a number bigger on a task manager...

Your philosophy is absolutely correct. In Windows that might be a good thing, because it starts buffering to the HD when you run out. But Android will just close some background processes automatically to clear ram as needed.

Unfortunately people these days only know about ram management from that poor excuse of an OS called Windows.... excluding 7.

Agreed, as long as there is a big line between FREE RAM and TOTAL RAM. More total RAM is always a very very good thing regardless of how good the ram management is.
This thread is about total RAM available to Linux/Android, so it's good imho.

Are we getting ripped off with our RAM?

So, I just played with a friend's SGS 2 and when i looked into his App Manager, it would say he had 500-600 MB of free ram. Now, no matter how much I wipe or how many processes I kill, I cannot go over 450MB from the "1 GB" we are supposed to have.
I thought It was android reserving some RAM for himself but with this comparison it doesn't make sense anymore. Any recommendation on this? Might be because we have webtop running on background and SGS doesn't?

I usually have between 500 - 600 mb of RAM available... all depends on how many apps & process you have running.
Webtop does not run unless it is being used. As far as the difference in usage, I think Motoblur just uses more resources. I use Bloat Freezer and i can get up to 600MB free like when I reboot but then processes start up and it goes to about 500MB. Then I'll use it for awhile and it will get down to 200 to 300MB but never any less than 200

I don't have that many applications installed. And even so, the installed applications shouldn't be taking up RAM unless i run them, right?
I just did a restart and checked the RAM and it was just at 471 MB. I might mention that I'm using Go Launcher and the stock launcher is running also, because if I freeze it with Root Uninstaller, the calendar widget won't work.
Any guide on how to optimize RAM usage or what bloat should i freeze/uninstall?
using CM7, have around 400MB free out of 820 or so at any given point in time.
879mb of ram doesn't = 1gig. I would like to have that extra 120mb in free ram. instead of 600, 720 free. When I go into "About Phone" it used to say the current amount out of 879 but now it seems I've lost 100mb of ram. I've wiped/flashed/rebooted countless times to no avail. Even used Aura deblurred and CM7 with almost the same results.
On my phone it shows 471/816. Yes, would have loved to have that extra 208 MB of ram... But still Swiftks, could we have some info on your mods/apps? 600 MB of free ram is a LOT compared to what we have.
I have used ROMs that showed 575-620mb free but usually after rebooting. I'd say most ROMs will run from 400-500 free. But if you could, look on your phone under running apps and add up your used and free ram and post back.
I've heard that Go Launcher is a resource hog. Might want to try it without that just to see if there is any difference.

There's a huge misconception about how much RAM should be free at any given time. Honestly, the less RAM being used is actually better. That means processes are cued up for multitasking and it uses less resources to start them back up when used. Also, if you have any RAM left then that means you don't need any more because the phone will only use what it needs so if you have like 100MB of Ram available then that means you don't need it, but if you were at like 10 to 20MB free then I'd worry. But most people say they have like 200 available so there really is no reason to worry/complain. Plus, it's better for the battery to have the processes stored in RAM because it takes more energy to start an app back up then to keep it idle.

If I add up the mb's of apps running right now it's less than 90mb but its showing 190mb is being used. That is including the media/motorola/stock junk on a fresh install of ninja. I haven't even opened market or added my google account yet.

I understand your point, but it makes me wonder... Devices like SGS 1 for example, only have 512 MB ram. Based on how the Atrix and Galaxy S2 are said to have 1GB but in reality it only has 800ish MB, the SGS 1 will also have 400+.
Now, my atrix goes from boot to a usable state leaving me ONLY 471 MB of free ram, taking up 380+ (rounding numbers of course). Since the SGS 1 also runs on Android 2.3, the same thing should happen right? taking up 380MB out of it's 400+ MB of ram, leaving only 50 (rounding again) MB of RAM? Highly unlikely, if that was the case, only opening up the browser would take up those 50 "free" RAM.
I don't have a SGS with me to corroborate this theory but I'd bet the SGS starts up to a usuable state with 100-150 of free ram, using up only 250-300 MB of ram, why can't we pull that off from our devices?
It's not that I'm not against using the RAM on our devices, but only comparing how much RAM my device is using I can tell whether it's running efficiently or it has a resource Hog somewhere.

your phone is like a fat kid with a birthday cake. he's always going to take a few extra slices for himself and not share with anyone.
(system taking RAM and not sharing with any other processes)
I think it has to do with Motoblur using up more resources. It is so integrated into accounts and everything that it can't help but take up a bunch of RAM which is why they probably went with 1GB of RAM to begin with, they probably couldn't pull it off with just 512

So deblur is the way?
I use Bloat Freezer and the paid version of TiBu freezes apps too. I think there is a list of "safe" Blur apps to freeze somewhere. I'll see if I can find it.

[Q] Simdo D98T fake RAM size

I purchased a Simdo D98T from Pandawill. While the phone isnt pretty and the touchscreen is not well calibrated, I was impressed with the antenna quality: best wifi and GPS I have seen in any phone.
The phone reports 1G of RAM, but the lowest I have seen free RAM has been around 639MB. Programs are closed as soon as you put them in foreground and Firefox even closed on me while working, while still reporting around 640MB of free RAM.
Can the manufacturer reportan incorrect amount of RAM and tweak the kernel to use only part of it?
>...
The RAM might have been used by system.. Actually 1GB RAM should be 800MB+ available for users.

Thats the issue: the kernel closes programs and available RAM never goes under 640MB.

How much ram your idle phone use?

Hi, i just wonder why this phone use ram so much high? (mine: usually at 1,7GB). At first time i use this phone it was used about 1.1GB of ram.
I'm trying to compare this phone usage with my previous tablet, samsung galaxy note 10.1 and it just consume about 700MB of 2GB ram it have and at first time i use it consume about only 500MB ram.
For your information, i use almost same app running in my booth device. But..
Why it come so much different? Z2 for sure have 3GB ram (bigger than other) but i think the system at least consume much more ram too than others. Are I'am right? Can u tell me what do you think? And tell us about your idle ram usage too if u can..

I think nothing of it
Linux is healthy to use ram unlike other OSs when ever you open an app your phone will free ram if needed, its not to hard seeing as how its managed
Your actual free ram is always 15mb but freeable is usualy always %90 of your total ram, ignore how much ram is avaliable
If you want to know more, look up linux ram management

Looking at RAM usage is entirely pointless.
Apps allocated RAM as they like but the operating system makes all kinds of predictions ahead of time to preallocate blocks of RAM to increase speed, eg when an app requests to allocate some memory the OS gets to instantly go "here you go; hehe sucker I already prepared that earlier".
The OS will more or less allocate as much RAM as you throw at it up to realistic limits. Eg once a tiny app has 1gb of ram the OS will take the educated guess that will be more than enough for it and not allocate any more.
If another app opens up and the OS is running low on memory it will rejig how much it has allocated to apps that never actually requested that much memory.
This happens on any modern OS and is why you should never really care how much RAM things are using.
In Windows under process manager if you looked you would find there is about 10 different ways to look at the RAM usage per app. Unless you really know what the numbers are saying they will all means basically zero in the real world.
Woa.. I never know it before.. Thanks for the info..

How do I see this?
Skickat från min D6503 via Tapatalk
mine is usually about 1.5 to 1.9GB
keep in mind it caches apps too incase you reuse them, at the top right of the usage screen hit the menu to see the cached apps.
Mine is usually 1.5 to 1.7GB, even I don't run any app...
BTW, I install the app Clean Master ( like CC clean on Windows). And I always do clean Junk file and Boost ram once a day.
Is it good to use this app everyday?

If it's another generic 'ram booster', it's next to useless, but it won't be dangerous to use unless the app is programmed poorly. As others have pointed out, if there's no problem with the system (e.g. memory leaks), the RAM it allocates is used for caching apps so they may load quicker. Simply put, this behaviour is intended.
Cleaning junk files will probably have next to no effect on perceived performance as well untill you've hoarded enough junk files that your internal memory is almost full. But I see where you're coming from; it's very satisfying to see memory freed.
And while I am at it, I'd like to recommend SD Maid for this purpose. It's one of the few apps that actually do something useful. You can delete orphaned folders by apps that are no longer installed, delete junk and duplicate files, bulk clean app caches as well as optimise internal app databases.
