I noticed in the "about phone" that my Droid 2 only lists 475MB of total RAM. The Droid 2 is supposed to have 512MB. Anybody know why that is? Are all Droid 2s like this? Where did the rest of 512MB go?
Droid 2 - Rooted
RevNumbers' CM7 GB
It does have 512mb of RAM. Every device that has RAM does this, even your computer. I believe it's used for the operating system (Android).
I figured maybe the OS had it set aside for something thereby reducing the amount of RAM that can be used. But I just looked at the system on my Nook Color running MIUI and it shows 512MB. CM7 on my Droid 2 and MIUI on my Nook Color are both GB based ROMs so I would think they would treat RAM the same.
Available RAM or storage capacity is always a bit less than total.

Hi all,
I am getting this phone on July 21 when it's avaible through T-mobile. However, I ran across an issue while reading on the vast number of threads about this phone regarding the available memory.
1. Is it true the Android 2.1 is limited to 256mb of ram unless "hi-mem" is installed/enabled by the rom?
2. Is hi-mem enabled on the SGS stock rom? From my reading it doesn't appear that it's properly enabled.
3. If hi-mem isn't enabled, does that mean the SGS is functioning with only 1/2 of it's ram?
4. If so, how much free ram is showing on the stock rom and how much should we see once hi-mem is enabled?
I'm assuming that since many Android phones come with 512mb of ram these days, that hi-mem has been properly enabled on some of them. How much free ram does a typical android phone running 2.1 or 2.2 have after bootup?
I'm currently using a Touch Pro 2 which runs out memory all the time and would rather not have to deal with that on Android as well. I assumed that 512mb is supposedly to be more than enough to run 10+ programs at the same time should I choose to.
Thanks in advance.
It doesn't appear to be using 512MB I only ever have around 100 meg free. I used to have a touch hd and know what you must be thinking but i can assure you even with only 256 available it is fast and hasn't run out of memory on me yet. be sure to download a memory freeing app like task killer.
It runs quake3, something i could never get my hd to do with out practically killing the os
Kernel supports 512M RAM.
with the new Gingerbread specs it REQUIRES 512MB .. now if its 256MB , that's something to worry about

Don't worry, it has 512mb. It's just that some older kernels didn't support more than 256mb of ram, so the phone simply didn't "see" all 512mb.
My concern was that the kernel out of the box was too old to support the full amount.
The phone physically has 512MB of RAM. However, I think Android 2.1 is limiting the availability to 256MB.
Froyo 2.2 will correct this issue.
My tw taskmanager shows only 340mb ram instead of 512mb, after some research I found that the rest of the ram is used for ramdisk,is that true?
If so,is there a way to use all of 512mb for ram?And does this make Epic inferior to Vibrant,Captivate and Fascinate or better?
All Galaxy S phones have 512 MBs of RAM. And I do believe all are the same. At least the i9000 and the Epic are.
The phone has a physical 512MB of RAM, but I don't believe that the stock kernel currently supports more than 340MB.

Check your built in taskmanager(by holding home button),it only shows 324mb total ram,so no they not all the same.Yes we do have 512mb but only 324mb(give or take few mb) is used for actual ram,the rest is used as ramdisk(cache).Vibrant and Captivate uses whole 512mb as ram and internal rom(hd) for cache,im not sure about original Galaxy or Fascinate.
Believe me extra ram not being available has huge impact on performance,i owned MT3gs with 512mb ram and 600mhz cpu and it felt just as fast as my Epic if not faster even with Sense.
This could explain big lag im getting with 4-5 apps open,i could have 10 apps open on Mytouch slide with no lag.

There is a reason why. There is no dalvik cache push to sd for our devices yet. If we could get an ext2 or ext3 or ext 4 for our sd cards and move the cache there, it would be a whole new ball game. But it's no availible for us yet
Maybe to balance the phones out because epic has 2 cameras and keyboard

I wonder if other models have same ram or they have full 512mb of usable ram without ramdisk,and does that makes epic faster or slower?
I know my MT3gs was way faster with stock sense 600mhz cpu and 512 ram(without sd cache),sounds like this phone needs that extra 128+ram because extra ram makes more difference than faster cpu,324mb ram I dont think is sufficient for 2.1 to run smoothly.Hope someone comes up with something so we can use whole 512mb as ram and internal rom or sd for cache.
The reason why we have only 320 showing is because samsung moved the cache there to prevent the lag some people here talkming about the galaxy s having.

EPIC FAIL ...325 for me :-(
2012 the Evolution of Human Consciousness
supposedly the GPU uses 128mb of the ram
All 5 galaxy s phones have 512mb but the epic and fascinate are limited to the 300 and something because our phones are the only ones that don't have a massive amount of internal sd like the others. We ours uses the more typical smaller amount of rom and the missing ram is used to stop touchwiz from lagging! Why do manufacturers and carriers keep ****ing up android!? Love this device but I can customize it myself just fine without the extra tw layer eating my resources and slowing my upgrade releases!

We have 512mb rom which can be used for cache,i have all the apps I need installed in /system/app folder and still have 400mb free,how much should be dedicated to android swap 128,256?So there is plenty of room and for those people that have about 100 apps on they phone they need to wait for a2sd.
Still no one has answered if its possible to use whole 512mb for ram,this phone really neads it,most of the time I have 3-4 apps open and about 80mb ram free-thats not good.Epic has fastets rom out of any model,now if we could use it for cache and a2sd for apps,plus whole 512mb as ram,than this thing would fly.128 for swap is a waste,plus I think that this 128mb actualy takes away from GPU's vram.
I agree that we need more RAM. There has to be a way to edit the kernel and get more out of our hardware.
just a quick question. after reading about the specs the iconia a500 should have 1gb of ram. in application settings it looks like it adds up to 512mb? is this correct?
This is not correct. Go to Settings> About Tablet>Device Information and scroll down to RAM size.
okay thanks. I'm actually at staples now and. Checked the xoom and the iconia displays and they have the same issue
I believe the 1 GB advertisement (on Xoom and actually all other Honeycomb models), is 512 MB of onboard ram, and 512 MB for the video card.
Thus adding to 1 GB.
I believe this is a "standard" (yeah, frustrating, but true). All Honeycomb tablets advertising 1 GB of ram actually mean 512 MB onboard, and 512 MB on video.
thank you so much for clearing that up!
I believe it is 1gb of system ram (possibly shared on demand with the video hardware)... Using Advanced Task Killer when I clear the running tasks I see 445MB free. There is no way the system is running on just 55MB. I'm guessing Honeycomb just uses a lot of ram in background system processes.
The running applications on mine are using 149MB with 455MB free right now but I don't think that number accounts for all of the background services. Anyway it's not a dedicated 512/512 ram split.
I'm only getting 1.58 GB and after the reboot my ram usage is like 1.31/1.58. I know it's 2GB device. So the question is why only 1.58gb can be used and how to increase it to 2.0gb? Anyone?
Cause probably the rest of the ram is used by core (not Android os) and hardware
Mine is 1.82 GB. Which is normal due to the conversion discrepancy between MB/GB.
1.82 or 1.72. Can't remember and don't want to look right now
The only way to increase it is by using swap. Either with an app like the rhoesoft ram expander (I think thats how it's wrote), or with a rom feature. But the ram you get with swap is not as fast as real ram. It will also degrade the life of the storage in that it is being stored. You can google more info about swap.
Are you sure you're reading it right? I usually have 1.2 GB ram free.
If you have 1.31 from 1.58 free then maybe you should consider uninstalling some apps. Cuz that's an unusual lot of ram usage

2000/1024 isn't 1.82. And I don't know why mine shows 1.5. That's a 300 missing. I'm on 4.4 tw.
It's just like HDD's. You buy one with 500 GB storage and when you set it up it shows only 480 GB or so.
And yes, samsung kinda ripped us off. 9 GB of internal storage is not 16! and 1.82 GB ram is not 2 GB! It's basically false advertisement what they are doing..
I saw this phone has 2.5 GB of ram and i read that it is because it has the other part for the system but i have also a Nexus 6 and it runs smoother.
This phone doesn't have better multitasking and i think it is for the missing part of RAM memory.
Moto X Pure has 700MB of Android OS
Nexus 6 has 478MB...
I have tried CM13 and Stock and truepure.
No.
That is not...
Just no...
Our phones have 3gb Android pre allocates as much RAM as it can the best solutions to your issue is just load a custom ROM if you go with asop based 6.0.1 it will mostly make this phone a Nexus
One way to look at it...
Why does your GB variant (16, 32, 64) not actually have that much available storage? The system is allocated some of this storage. RAM is no different.
As far as system allocation differing between different phones, there are potentially several reasons. Remember that the MXPE is not pure vanilla with Moto having some of their stuff baked in. This can make the difference. Also differences in Android version can be a culprit along with differences in any custom ROMs.
Some is likely allocated for the GPU, also there is zram (think swap in RAM or compressed VM, much faster than disk r/w), etc...
yes , i am with stock rom and just rooted , there is 2.5gb ram and free available always around 350 to 500mb maximum available , it does restart apps in 5 or 6 apps multitasking
