So I went into "Running Services" under Settings --> Applications, and I found numbers that didn't quite add up.
Other: 124MB in 4
Avail: 220MB+170 in 44
What does this mean? I understand not having the FULL 768 available, just like storage cards don't really access all 32gb, but this number seems far more off than expected. Is this normal?
My gut says that it is reporting the RAM availible after the CORE system usage. So 768 less what the system uses gives you the total you are seeing.
I could be wrong, but that's my 2 cents.
Haven't seen any Android devices report proper memory.. its gotta be after core services.. I can get my available memory up to 430 meg or so.. so it's definately much higher than 512mb found in most phones.
Only see about 330meg free on my Galaxy Tab which has 512mb.

Well that could very well be true... that just means SENSE and Bloat are really chewing up RAM... oh well. Root will be here before we even know it..

The EVO 3D is basically the same phone as the Sensation with the addition of 3 extra Gb of RAM. The spec sheet for the Sensation on HTCs site lists 4Gb of RAM with a note that only 1Gb is user accessible.

I remember when T-Mobile's version of the HD2 came out and it had 768 Mb of RAM vs the 512 in the European HD2s and there was a way to unlock the remainder of the RAM with a hack for the Euro models.
I'm sure given HTCs track record that they've used the same hardware (makes sense) to cut down on costs so it's just a matter of a hack from the community to unlock the remaining 3Gb of RAM.
What say ye?

I guess you mean ROM and not RAM...and I've read that it is not possible...
Sure just buy a couple of DDR3 sticks and jam 'em in the microSD slot.

No, said RAM, meant RAM....
You can do the research, I was going by memory but it actually had 1Gb of RAM vs the 448 in standard HD2s. The Euro HD2s had an unlock that at least gave them 576 Mb, I'm guessing the same will be true here.

As you said in your first post, the Sensation is listed with 768 MB RAM, 4 GB Internal Storage (1 GB user addressable). Some of the 768 is then used for Android and Sense, with the remainder being open to run other applications. The 4 GB with 1 GB user addressable is NOT RAM. RAM is volatile (non-permanent) memory that is VERY fast and used to store the data for a currently running process. The user addressable space is non-volatile and is used for permanent storage of applications, contacts, photos, etc. It is not possible to use this as RAM as it is flash memory instead of using capacitors like the RAM found in cell phones (which provides the speed needed).
Some of the remaining 3 GB might be open in the future after the bootloader is unlocked and custom ROMs are flashed as they would be less memory intrusive than Sense. This might also free up some extra RAM from system use, but there is no possible way to increase it beyond 768 - whatever vanilla android requires to run.
Everything I have seen on the internet (including HTC's own specs page) shows the EVO SHift having 512 MB of RAM. However, it seems as if my system only has 368 MB (as detected by V6 Supercharger and a couple hardware info apps I downloaded from the market). Does anybody know why this would be the case? My phone is newer (just got it a little over a month ago). Could HTC have lessened the amount of RAM in the new Shifts?
Also, I am running MikShifted-G v1.6 if that makes any difference.
Mine says I have 367,haha, i believe it might only show total available after all the system android stuff... I am probally wrong because I have AOSP which is so much smaller and less bloated that your sense and i have less.. Haha.. But idk... Just speculation

Thanks for the link, but I'm just talking about total RAM, not amount free. Everything indicates I have 368 MB of RAM (not internal storage or ROM or anything, but actual RAM). The Evo Shift supposedly has 512 MB, but I know the HTC Merge has 368 MB, so I was wondering if they lowered the RAM on the newer Shifts.
To check the RAM, download the app Android System Info. It is not Internal Memory, but RAM. Mine says Max 368 MB.
My mistake

They're talking about internal memory on the phone. Are you talking about an sdcard?
Its possible the gpu has an amount dedicated to it that will not be shown. Sort of like checking the ram on a laptop will show less than the stated specs
So every spec sheet I've seen for this shows it has 768mb of ram. however, I was just looking through the ram use of an in store model through the "running apps" tab in the applications menu, and noticed that the amount of ram listed under "used" plus the amount under "free" added up to far less than 768, more like 500 or so. at first I thought maybe Sense/Tmo modded the menu to hide the RAM that Sense and some of the bloat apps eat up, but then I noticed many of the bloat apps were listed.
I also notice that my phone at this moment lists 149 used, 172 free. 149+172=322, yet my phone's spec sheets all say it has 512 RAM. so where is the rest? does Android itself hide its own use or something? or is it another reason I'm totally missing?
I believe some memories are shared with the graphic card and some reserved for the camera.
And memory is partitioned too.
Cedde is right, some memory is dedicated video memory and not available to the rest of the system.

I didn't notice this in my first 16GB Tab, but on the 32GB tab, if I open the Task Manager through the minibar, it shows 775 MB total ram I know we are supposed to have 1GB ram, so I figure the 225MB missing is due to god knows what, that's not an issue.
If you go to Settings, Applications, Running Applications, it shows you have only 512 MB ram......the real question is, which one is it?
I also noticed that in the 16gb, but ignored it since the usage of ram in the ram manager exceeds 512mb. What's bothering me is why do the usage of ram differ between the ram manager and the one in running applications.
This was the first thing I noticed when I turned on my 7.0 plus for the first time when I got it on Christmas day. I just disregarded it but I am happy I am not the only one who is curious as to why it is saying 775 MB of ram.
If you take a look at /proc/meminfo you can see the kernel only recognizes 775 MB of memory. Guess that explains why it felt like apps were closing more frequently than on my 1 GB phone.
Question is, why are we getting less than memory than was advertised?
On mine:
Code:
# cat /proc/meminfo
MemTotal: 794900 kB
We are getting all the memory "adverstised", but you have to remember that things like the kernel itself and certain other things take memory before hand. The same thing happens on android phones.
Well wouldn't that still show it as being "used" so to speak out of the total 1GB or 1024 MB? Or does the kernal just allocate itself and then let everything else take over from there?

I honestly don't remember. I wouldn't be concerned, however, about the lower number. It's perfectly normal on the few android devices I have.

I believe it's RAM reserved for GPU and a few other things, like the Samsung MFC and camera interface.
On Captivate, some of the "speedmod" kernels changed the reserved memory sizes to free up user RAM - but often reducing the reserved memory can break stuff. (For example, trying to port those changes to Infuse caused the camera to stop working, along with video decoding acceleration.)

Keep in mind this is the Linux kernel plus android.
In this case the system shows how much memory is available after the Linux kernel and android overlay are loaded. the galaxy 7 plus has 1GB of ram.
Now if this was straight Linux without android you would see the full amount of ram listed.
When I go to Antutu or Ram Booster they say I only have 1794 mb of ram what happen to the other 250 mb?

Nothing wrong, the rest is for system, GPU (in short)... Not all the RAM is available for the userspace.

As far as I know, at least for all devices I owned, it's always the same thing (some devices with 1Gb RAM had something like 768 Mb available stock)...
There is absolutely nothing wrong with the available RAM detected from Antutu or RAM Booster or another apps.

It is like that for absolutely everything. PCs/Notebooks, Tablets, Phones, etc. It's normal.
Just remember one thing that with a build.prop edit (by adding a line) you can fake the available RAM in Settings/About phone (like you can show some CPU info), but I don't know if some apps detect it (I think but... not sure ).
Maybe something like "ro.product.************" .
Maybe a Google search will give you the trick, just a cosmetic thing since the real available RAM is "hardcoded"

Yes, but those are dedicated "add-on" cards and are generally limited to PCs and gaming notebooks. The OS would still be using the main system memory. If you had 16GB RAM, the OS and any other processes would be using it regardless. You would never have 16GB available to you. Also, even if you had dedicated memory on the graphics card some of it will also be used regardless without your knowledge.
Any SoC uses the systems main memory.
If you want the full 2GB available to you, have fun never turning on your phone. If you want 2GB only for you, then the system has nothing to run on.
Memory is there to be used. Having a separate section for the OS and 2GB only for your choosing is pointless and inefficient.

I think what the OP is trying to ask is why is the hardware only detecting 1794mb of total actual RAM? Not how much ram the OS utilizes.

I don't have a problem (well I do but not as much) with the OS and GPU use the 2GB of ram I have available but it should be something like like 300mb out of 2048mb (300/2048) of available ram not just cut my 2Gb of ram to 1794. What if the OS only needs 200 I still would not have 1894mb my max available ram is always 1794.

its not out of 2048MB for one
its 2GiB, not 2GB
from wikipedia
Although most manufacturers of hard disk drives and flash-memory disk devicesdefine 1 gigabyte as 1000000000bytes, software like Microsoft Windows reports size in gigabytes by dividing the total capacity in bytes by 1073741824 (230 = 1 gibibyte), while still reporting the result with the symbol "GB". This practice causes confusion, as a hard disk with an advertised capacity of, for example, "400 GB" (meaning 400000000000bytes) might be reported by the operating system as only "372 GB" (meaning 372 GiB). Other software, like Mac OS X 10.6[5] and some components of the Linux kernel[6] measure using the decimal units. The JEDEC memory standards uses the IEEE 100 nomenclatures which defines a gigabyte as 1073741824bytes (or 230 bytes).

2 GiB is 1024x1024x1024. HDD / MMC / SSD use GB (1000x1000x1000) not GiB, however this is for storage. RAM is usually binary 1024... so it most likely is out of 2048.

Oh, well don't worry, you have 2GB RAM. It might just be the way it is displayed in Antutu. CPU-Z displays the total amount of RAM as 1855MB. Not exactly consistent between programs.

I will just try to ignore this and I will be happier I guess, my cpu-z still says 1794MB total ram.
The device has 2GB of RAM but you the "BIOS" or whatever controller is in there allocates some for itself and the hardware in the phone (mainly GPU) and the rest is left to the OS.
Sharing RAM is good in general but many systems require X amount of RAM whether it's actively being used or not as it's designed to be able to use it. if it were to call on that memory address and it's full the system would crash (or a STOP error).
So instead of sharing it and allocating it as needed, it's locked off totally from the OS in the event it's ever needed by the hardware.
