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.

only true if the ram is taken by cache not some unknow process/bloatware.

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, if the captivate had more ram, I'd still be using it.

+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!
Sent from my I897 using xda premium
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.

There is about 128Mb of swap.
What's your opinion about this?
would it be a big deal?

Actually I don't like the idea of swap in O3D
It may cause lags because we already have a dual channel 512MB ram
Is it necessary to have more 128MB of swap but slower? Also vm have to decide which is swap which is not swap...waste more cpu
Pls correct me if i was wrong
I added some "#" in /system/bin/swap_enable.sh...check it out
Yes it can cause some lags when dropping things to swap etc.
but maybe it can be sometimes useful?
Why lg did it in the stock ROM?
Do you notice any speed up after disabling it?
Yes before add those # I had some lags when finish an asphalt6 round, now lags gone.
On the other hand I thought because LG had a lot of bloatware in stock rom so they wanted to make sure there are enough memory, and they used swap.
I removed a lot of things that I don't need, tweak the minfree, vm, disable swap and everything still fine.

I did the same but it still shows about 36mb of swap after the restart. Strange. I hope there will not be the case when eg. camera app or sth else will crash because of the lack of ram
So there is still 36mb swap script somewhere.

probably you need to add 3 # in the beginning of each line. i did it that way and now have no swap at all.
I was mistaken. It's Ok now.
So what should we, inexperienced users, do?

Everybody can try. You need root explorer. Open /system/bin/swap_enable.sh as text edit. Then just add 1 # before each line (3 lines). Reboot and experience yourself.

As far as i know the physical ram amount will not bechanged. Only it will be re-emptied earlier than it is with swap, which is practically no change in total.
wow this is really quite an eye opener, to think that lg opted to use swap because they new 512mb wouldnt cut it is quite bad in my eyes. i wonder if we can increase the amount of swap and see if that makes for more free active ram? as i find games like GTA3 it bogs down as its quite a memory hungry game
it was much better if LG added 1gb of ram to our phone from the beginning thought. i decide to exchange my optimus 3d for a atrix, photon or galaxy s 2 because im a heavy multitasking user, 512mb is not enought.
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.
Well I'm using ES Task Manager and it shows 0.91 gb of total memory

I don't think you can download RAM.. I know you can add RAM cards on computers and laptops but they have certain limitations(plus, they are hardware which you have to buy and apply correctly).. and on an android phone I'm not sure.. so if you could provide more details it would be great.

Sewrizer said:

You can't increase RAM without the hardware (again, as far as i know). the only thing you can do is to use less RAM, thus making the device faster and more effective. try freezing the apps that you are not using with titanium back-up. a lot of apps work on background and you don't even need them. by freezing them, you prevent them from auto-starting. you can unfreeze them to make them work again. (you need to be rooted for this)

And then we get into the old falacy that "Free RAM is good". This is simply NOT true on Android. If you start running too short on free RAM then the Android system starts to kill applications to free up more RAM, but RAM is there to be used.

@OP I don't know if this'll work on your phone but on the HD2 at least you could create a swap partition on your SD card then flash a zRam script to increase RAM.

So you are saying it is bad/useless to kill/freeze unused background applications?

Useless? Not necessarily, as long as you know what you are doing and are 100% certain about the apps you are freezing. However, I have never seen any real benefit in doing so. The Android built-in task manager normally does a failry good job of managing the memory without any real intervention.

Manually killing them is something I do as well. I just don't buy into the task-killer type apps.
Sewrizer said:
I was suggesting freezing and killing unused apps on background because on phones with low RAM (his gio has less than 512 MB of ram) system is laggy, mostly because of pre-installed software which users don't use. He said he has just rooted his phone, therefore he can't have uninstalled the network carrier apps/social networks apps, which may be running on background. And in my experience as an android user, if anything is laggy or stops working, i restart the phone. And after restarting it always works smoother.
About the android built-in task manager, it does indeed do a good job, but on 2.x android versions is a little harder to find and use. thanks for replies

Freezing / killing the apps as root can be useful, but as I said you need to be certain what apps you are freezing and why. How many times have you read on XDA from someone who has frozen a load of the 'Background' apps, and then finds their device won't even boot up and they have to do a full flash to recover, often losing a load of data as well?

Hello,everyone!
I have a Nexus 5 whose ram size is about 2GB. Now, I want to change the ram size to 1G or anything else below 2.
Do you have any idea? If so, please share with us now. I'll appreciate that very much!
Someone told me that I might try the bootloader, but I havn't figured that out yet. Please help me out! Thanks again!
Hi,
But... Why do you want to reduce your RAM size????
RAM is allocated to user apps, system, GPU, etc... it's possible (for some devices) to re allocate the RAM for the GPU (a little more) for example at kernel level, but here you want to re allocate 1 Gb of RAM, seriously? Why? Even if it was possible, here what do you expect?
For other devices with an unlock bootloader it's the system partition size (I don't remember the exact name) you re allocate to be used for the user (apps), maybe it will be possible in the future for the N5?
But here, honestly, I don't uderstand why you want that

Firstly, thanks for your response!
Now I'm doing a series of experiments on swap partition. For the ram size of N5 is a little too large to make use of the swap area I created.
So I want to make the ram size small enough so that the device could run out of memory and would swap things out to emmc(swap area).
Have I made it clear to you? Looking forward to your reply!:fingers-crossed:
Hi,
Yes it's a little clearer, maybe, but why do you want that? What kind of experimentation are you doing? It's totaly counter productive...
Some apps like Ram Manager for example (Play Store) can create a swap file, there is also some kernel like Faux123 with, grrr don't remember exactly the name, something like Zramswap or... not sure...
But you don't reduce the RAM size, on 2Gb, you have about 1,8 Gb free for the system, apps and that's all, you can't reduce this part. At the end with a clean and light system booted you have about 1,6 Gb free. What you want will virtualy increase the RAM size (with the swap file).
In any case with the app above, use it to create and use your swap file, open one or two "big" apps, a game and you will see that it is used...
Tweak also the OOM settings to run Out Of Memory earlier, see Google.
You want reduce the amount of free RAM not reduce the RAM size. For me it's not the same thing.
Or I don't understand again, and I'm sorry. But I don't see the point...

Well, actually it's quite simple. The Nexus 5's RAM size is too large(ok, it's about 1.8Gb free or less). Even After I have run a lot of apps, there are still serval hundred Mb RAM free(Maybe I can run more apps, but it doesn't worth. Or I should choose another device with smaller RAM size. But that's out of my budget). Yes, as you said I want to reduce the amount of free RAM. But reducing the RAM size can also work for me.
All in all, I want to see the benefit of swap area through the experimnt?
Ok, my friend, you have got that right? It's ok, if you still feel confused. I'm glad to tall with you!
