How much RAM has this phone got and how much is free?
The phone is giving me conflicting information and I just don't understand it.
Settings - About Phone - Hardware information - 768MB
Setting - Applications - Running Services - 188MB used, 310MB free (498MB)
Task Manager - 558MB total, 451MB used, 107MB free
Loving this phone so far, but this memory thing is just confusing me.
Well you have to understand that ALL android phones, despite saying they come with 512/768/1024mb have to reserve some memory for the GPU. After you just boot, the memory available to the user will always be less than the advertised memory merely because of the GPU taking up some.
I would imagine there's 550mb or so after the GPU takes up some, then Sense 3.0 probably takes up a decent amount... so 300ish after a fresh startup sounds about right.
Keep in mind that having "free" ram isn't very efficient but having more memory in absolute is better since you'll be able to have more applications open before the system starts closing some to free up memory.

Thanks Dinan,
So android works like a PC motherboard with integrated GPU and shares RAM between the two.
It still doesn't explain the difference between the 'Task Manager' and 'Running Services' though? Is this just a software error?
Yea it seems like the android running services free memory counts "idle" apps as free ram where as a task manager will not.
For example my phone says 150mb free in running services but a task manager says I only have 44mb free which is pretty accurate since I set my empty app space to 40mb.

Ah, ok that makes sense now, was confused by all the different figures, thanks for the response.
Ram confusion
+1 thanx for the explanation.
had the same questions when i saw the taskmanager on my freshly received sensation
I Dont get it!
I have a New Phone! Nothing installed, Clean!!!
I just Bought and got my Sensation..
it says 558 ram and free 117 mb!
NO apps are on, and None installed by me!!! How can that be possible?
I have a DHD alssow.. and its aloways 300-500 mb free!
The phone dosent lagg! but mem makes me crazy

REAL available RAM is shown on "Running Services". Task killer is inaccurate.

well you can always run Launcher pro instead. And that might free up more. Let me know if im wrong though. but i think running Launcher as the default and not htc sense would free up some ram. if some one has tried it let me know what free space you get after fresh boot

Thats odd. I have all of my apps installed and have over 275mb free on a fresh boot.
Does anyone know how the internal memory of the Sensation is distributed?
The Sensation have 4gb of internal storage. 1.1gb is available for installing apps.
That leaves 2.9gb. What is using the rest of the space? I guess Sense 3.0 and Android takes up some, but surely not over 2gb.

yeah, I would like to know this too...even with a hidden partition for a backup ROM over 2GB is way to much...
The memory is 4gb but with mmc itends up being 2gb for back protection and the system/rom is about 800mb so that leaves you with 1.1gb for apps and about 100mb formating. Give or take a few mb on those numbers.

Sorry mate, I think I lost you. What does "back protection" mean in this case?
I mean the g2 had 4gb of memory too but the other so its split up into to 2gb secoins for backup. So you really only get 2gbs user space and that has your android system and your 1.1gb for user apps

take a look at this the sensastion memory is very similar
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#The_Missing_2GB
Ohhh now that makes sense! Thanks for the wiki link of the G2. G2 is a problematic name - I mostly think of the HTC Magic when referring to G2, not the T-Mobile one (Desire-Z).
So if I got it right, basically the eMMC is partitioned in a way that utilizes only half the amount of voltages - thus utilizing only half the theoretical space - in order to increase performance and reliability, right?

yes and the htc sensation rom is around 800mb so with formating it should leave you around 1.1gb give or take a little.
and the emmc is partioned that way permently so no why to change it to gain those other 2gb once we crack the bootloader

Well, trying to do so (which is impossible either way) kind of defies the goal for which we root in the first place - optimizing performance.
It looks like KJ3 ROM on captivate uses more RAM that KH3. To confirm this can I reuest guys to post their RAM usage for KH, KI and all KJ versions. Please use TaskManager to clear memory and note the base RAM......it may not be accurate but will give an idea. In my experience KH3 runs around 170 MB and KJ3 is at 230 MB.
Thanks for any input
im on a kj3 rom using about 230 myself.

Yes, but if you follow peoples comments on KJ3, like I am doing, KJ3 is using a much larger RAM amount, AND when further customized by adding apps, live wallpapers etc, is actually SLOWING the phone considerably. This making the phone real sluggish........which is new for a android ROM......??
EDIT: would you mind sharing your ROM and RAM?

I agree with this especially on the KJ3......Something is different in what is running in the background, and I hope I can investigate if this turns out to be true for other people.
I agree and went back to fatsy ki rom and it stays faster longer without lag.
I also monitor free ram and once it gets below 40, it lags badly, over 50 it flies.
I think this phone really needed 1 gig like the gs2

+1 I myself am willing to agree..........if this RAM usage is a consensus on KJ3 then maybe the cappy is reaching its last usable ROM update? This is important to know......
EDIT: Of course, since this a leak release, then ATT/Samsung are fooling around with this build........., and maybe come back to normal on next leak ?? As a captivate owner, I would like to know what life my phone has as a "advanced" device........

Fusion x beta kj3 267mb Ram used ATM. But no lag whatsoever.
If you find that the ram does get bogged down just on this firmware version then perhaps the lmk settings in the kernel aren't as aggressive, which would be easily fixed by SOURCE CODE.

Point well taken........
But due you expect LMK to let ~100 MB slip by? It seems a little too much, since the limit on cappy is about 370 (usable). I would think we so much consumption LMK would kick in earlier?????
My KJ3 is using 227 MB. Free memory is ~50 MB. It lags significantly at times. However, I used Auto Memory Manager and set the Android internal task killer to "aggressive" and it keeps ~100 MB free an there is not lag at all now. I haven't noticed (yet) that apps get killed prematurely, which could be an issue with this setting. I'm using the Samurai 1.2 kernel overclocked to 1.252 GHz (no Voodoo lag fix). Other than the occasional black screen on the Gallery, my Captivate has been running pretty fast and seems to have as good a battery life as I remember ever having.
Edit #1: I don't think Auto Memory Manager is needed with Samurai 1.2. This kernel is tweaked already. I set Auto Memory Manager back to default settings, uninstalled it, then re-installed the kernel.
Here's another tip, move all of your apps from the internal SD card to phone memory. Having them on the SD card cause significant lag, crashing, and rebooting for me.
Edit #2: I switched to Pinnacle 1.3 with the latest Boog's kernel, and my KH3 is using 329 MB (the same as KJ3 I was using before (I must have made a typo above when I claimed 227 MB on KJ3 (I verified this before I switched to KH3/Pinnacle)). What governs how much RAM is used? Does it really make any difference? Free memory makes a huge difference in lag, however.
On latest MIUI and i have ~200 MBs of free memory!

Surely not that much... M on miui too n the lowest I get is 80,otherwise I am up there at 130ish... But then I have a crapload of services in the background. But yes, I do get 200 when I clear memory.

Hi All, I have a question. On my Atrix 2, it shows only 672MB of RAM. I am noting that from Manage Apps --> Running tab. E.g., at this moment it says 249MB used and 423MB free. But I thought it came with 1GB RAM. Am I missing something? How much RAM does your Atrix 2 show? Many thanks for your help.

672mb + 423mb = ???
672MB I assume is dedicated RAM for performance, 423MB is available for apps and you're using 249MB of that 423MB for apps. That's my assumption.
I already summed up

Manage Apps will never tell you how much ram is actually on the device.
Much of it is reserved for other stuff and unavailable to the android virtual machine.

Ah, that fits, then. If you want to see what is actually on the device, you have to get outta the android GUI and into the linux shell. Use adb to get a shall and then run 'cat /proc/meminfo' for a full breakdown of total RAM and ram usage. 'cat /proc/cpuinfo' will give you a few tidbits on your CPU, but you probably already know most of that.
I'm going to assume that the linux kernel grabs a certain amount of ram for disk cache, kernel buffers, DMA, and some RAM for the video 'card' as well. I always felt 256MB was rediculously small for a smartphone. Even 512 meant a minimum of simultaneous apps. If yer IOS and don't let stuff run in the background it's no biggie, but not so much for android.

Hi everyone,
I notice my TOTAL RAM (not used RAM) is gradually decreasing. For example, my total RAM started at 1.79, then went to 1.69, not at 1.59. Is this normal? Why is it decreasing? What can I do to increase to total RAM back to out of box (or close thereto) of 1.79?
Thanks for your help.
Uhhh I just checked mine and I have 1.56 wtf. I swore it was 1.79 before I switched to jb tw.
Actual ram available on this device is 1.6gb on touchwiz...aosp roms might be slightly more.

Haven't you accepted OTA's since you first had this phone? The small difference in ram missing is likely because of newer firmware updates similar to, for example, the missing internal storage of your 16GB or 32 GB that is dedicated to TW. Couldn't the same hold true for ram since we don't get a full 2 GB out of the box? If you've used Odin to return to stock and your available ram hasn't changed to what you remember it was at, there's likely no getting that back.
My max has been at/around 1.62 GB of ram FWIW.

Mine is also 1.59. If everyone the same it being used by new OS/firmware. If you are even close to using it all need to kill some apps running apps.. I have 200+ apps on mine and still only using half of it.

Yes I've accepted OTAs. Currently on VRLHE. Not sure what happened to RAM. Just don't like to see it going down like this. maybe future OTAs will help.
They are obviously reallocating it somewhere, maybe the gpu?
1630 ram here on AOSP.
Couple things, touchwiz hogs up a lot of ram, so if you are on a touchwiz rom you WILL have less ram. AOSP roms use far less ram, so if your on AOSP you'll have a lot more (hence me having 1630). Free ram is wasted ram as well, if its not being used then its being wasted. And finally as updates come things can be relocated to other places, just because you can't see it doesn't mean its not there and not doing something helpful

Agreed. 2 gigs of ram (1.6x actual ram) is more than enough ram. The reason why so many phones now that have 1gig of ram run slow is because so much of that ram is used by Sense, touchwiz, motoblur, etc which slows everything down. That's why AOSP is nice to have as an option because you get so much more actual ram to use thats not being sucked up by manufacturer skins. Getting 2gigs is a huge plus solely because of the touchwiz UI, because if we only had 1gig like the international version we'd be stuck with things appearing to run slower than they should.
