"Where's my RAM?!"

SetCPU and "RAM Usage" only show 408MB of total memory (I'm using ShadowFrost kernel).
Where is the rest? Is it just reserved for the system and the gpu and it's not visible to the user?

Yes that is correct, the remainder of the RAM is reserved/used by the Android system and i would imagine that some of that is also utilised by the GPU.
Your total ram usage should only show 400 Mb, but because of the modified kernel hack, you get the extra 8 Mb

I'm not sure,but its impossible to get 512mb ram...most I can get is 220mb free ram =\

You can't get more RAM than 330MB or so, the rest is for the radio and possibly other system stuff. Why is it a problem though ? Typically (running 2.3 at least) there should be lots of free RAM.

I saw 512+ before as total ram

That's very interesting because I saw 512MB too but now I have 368MB. Don't remeber when was it probably before rooting and flashing. Is this correct that task manager reports only 368MB as total memory?
Now I have Virtuous Affinity 2.05 and HBOOT from virtuous page. Is this could be the reason?

I always get around 250mb ram rarely 310mb :O

If its the value in About Phone - Hardware Info, i think that can be set to show anything you want in the build.prop file. The most accurate method to check RAM value and free RAM is using "free" in Terminal Emulator.
As discussed, the 512MB is shared between the phone, radio and graphics

New app in Market!

Guys.... I love multitasking and love memory available so ...
I was looking into ram manager app and suddenly came over this app named SWAPit.. It's supposed to expand ram by making a swap file. Any opinions? Or other suggestions?

Did you dowload it??
Maybe you could give opinions so we all can learn...and not download if it's ****e

Since setcpu and juice defender fall into placebo apps category, me thinks this falls into the same category as solar charger.

how to use it
Sent from my MB525 using XDA

I don't think this will improve performance. Usual Linux based OS use a swap partition. You can use one in Android too, but no devs recommends it. So i think devs don't recommend to use swap, because it doesn't improve performance.

Yes, swap partition will "extend" the RAM but the truth is Android has its own mechanim to manage apps, so if you're low on RAM, instead of killing an old app you'll slow your system as it will use the swap partition (or file) which is much slower than RAM.
So, let Android do its job !

I will give it a try and report back.

Free memory problems on One X

I don't think this is a problem but I would like to know if there is a way I can keep the used RAM on my One X below the 700 mark without having to use the task manager to close apps. Even when I have closed all apps and nothing is open I still have 600mb used. I'm running latest version of viperX and it runs perfectly.
If there is a way I can clear some memory I would appreciate the help thanks

Welcome to Linux. Free RAM is wasted RAM.

[Q] increase RAM capacity

Hello frnds,
Is there any way to increase the available RAM on our phone, means we have got around 700mb available whereas its actual announced capacity is 1Gb,
In a latest Xperia, Xperia C, being the same 1GB, its showing around 900Mb..!
Don't ask why to bother about 200Mb, because it does matter a lot for me
Thanks in advance.. :good:

Try to use this app: RAM Expander

Dont do anything like ram expander. That works fine but decreses the life of sd card.
Sent from my LT26ii using xda premium

You need to do some reading on RAM. Unused RAM is wasted RAM.
As for why you're "missing" some of it, blame it on Android and the GPU.

Add some memory managment-init.d scripts then!

Anyone got a performance boost by using any of the swap creating apps out there? I tried a few apps but all of them eventually led to my device slow down and lag to no end!
