Missing ram? - Droid Eris Android Development

I recently got my Eris, and downloaded a free ram widget. It tells me that I only have 186 MB of total system ram, and I run at about 40 mb free.. usually. So I'm wondering where the other, about 120 mb is at?
Edit: Can a mod please move to the correct forum? Sorry.

288MB is total. We already went thru all this on the G1. First off, part of that is shared memory. The baseband requires something like 40-50MB, then there is another 10MB or something for kernel, then another 30-40MB that is shared for camera, audio, gpu, framebuffer, command line buffer, and all kinds of neato things. We also realized that about 2MB just disappear into the ether. The G1 has 192MB total RAM, but only 96MB is available to the kernel, and with the RAM hack we get 107MB total.

[Q] Locked RAM - is it possible to unlock?

Hey there!
I've read, that the gt540 comes with 256mb ram, but you can only access ~160mb on stock roms. Is there any way I can unlock the remaining ram without installing a custom rom? (I have the 2.1 stock rom) Thanks for any replies
Sorry, It only has 128MB of RAM.

That's wrong. It has 256mb. You can only access 160mb, because the rest is used by system I think.

If it had 256mb ram
LG Would of Released Android 2.2 if the GT540 had 256mb of ram. Proof, LG Optimus One
Our phone has 256mb of ram, but we are able to use only 160 beacose the rest of it goes to video chip for rendering. In lg optimus one video chip have his own ram.

It does not have 256MB of RAM, otherwise we would have well over 100MB of free memory w/o odexing 2.2.

Lear to read system can use only 160 beacose rest is reserved for graphic and other components. You will never see this ram. In our phone memory chip is 256MB and that is a fact.
its possible to hack into the system and change the amount of MB's. but it can only add like 5 mb, and i am not gonna spend my time hacking my hardware to add 5 mb

Actually, there is no way to physically hack the RAM to give you more, it's just not possible. Although it is possible to add virtual memory, but this will kill your phones Internal NAND Memory or SDCard quicker as the read/write cycles will increase dramatically.

576mb RAM?

I am wondering what is the deal with our HD2 (TMOUS version I have), supposedly our phones have 576mb of ram internally, but on every rom I have tried I am limiting to something much lower according to running services or quaddrant system info, I have flashed 2.15.50.14 radio which is supposed to have the 576mb of ram, from my understanding the phone shares 128mb of ram for video which leaves 448mb to use but I don't even have that according to running services. According to my phone I am using 90mb of ram and 292mb are free which is a grand total of 382mb of ram my phone has access to, where is the other ram?? I am getting really frustrated searching google and stuff trying to find answers, I know its a difference of about 64mb that I think im missing here but its the principle that our phones should have 576mb of ram and im over here getting 382 on every rom I try. Anyone have some ideas on this??
I would like to add that I just checked quadrant system information and this is what it says.
Memory:
Total: 421004 KB
Free: 172356 KB
Inactive: 46692 KB
Doesn't this mean about 50mb of ram is inactive? I don't understand the deal with that.
The missing ram is taken by the GPU.
Please reread my post completely, I think you missed something, I covered the gpu using some of the ram in my original post.
i would say those figures are 421MB total ram, 172MB out of 421MB is genuinely free, and 46MB is loaded with apps that have stopped but not been unloaded from memory.
Example, mine says
421004
80228
85188
i start a few programs and go back to quadrant, and it changes to
421004
85140
88916
As mentioned, the graphics chipset takes up 128 meg, and it grabs it before the OS has even loaded, so it never sees it, so you start with 448MB total. For some reason Android loses 25 or so MB, and so we all (tmous and regular) show total RAM as 422 or so.
As said the system and the GPU takes it. Come on do you think the guys who made linux would really be as stupid as to just leave out some ram for no one to use or for it not be used? Or any person who makes an operating system?

Only 528MB of RAM? [Solved]

Hi, I've just noticed that if I go under Settings>Applications, I see 144MB used and 386MB Free, resulting in a total of 528MB of RAM, so I am wondering what is going on with the almost half gigabyte of RAM missing, is this allocated for the OS?
Buddy, what you're seeing is free ram and ram used by your apps. The ram you are NOT seeing is being used by the actual OS.
thanks buddy, that is what I was actually thinking.

Get use of full ram on sd build

I use American Android build and I want to use all my ram, we're supposed tohave 512 mb but with almost everything but the essentials closed I only have 250 - 260 available at best. I have some apps that use a lot if juice to run like gta3 and I can't get it to run smoothly. What can I do?

250-260 is very good. I only get around 250 straight after startup, and generally 180. Think about it logically, how the hell are you supposed to get 512 mb of free RAM when the entire OS has to utilise it? Have some common sense
( its not 512mb starting total, its 576 less 128 gfx less the 20/30 meg android somehow loses = 411-420 meg total ram, and then subtract whatever the system components use)

[Q] (Q)T-Mobile hd2 shows 403 MB RAM

I have T-Mobile HD2 with T-mobile logo and colored buttons. But ram size and device memory size shown low in hardware info. I have 2.0.8 HSPL.
Is this a fake T-Mobile..
Hardware info:
RAM: 403 MB
Device Memory:663MB
SD:14,2 GB
running android? all hd2's show around 400 - 411 meg ram when running android.
Also, the first 128 meg is taken by the graphics hardware, so it is only showing 40meg lower than expected, not 160+
Yes andoroid is running on it, I read about 128MB ram but still 40 MB is lost. and why device memory is 663MB . mgldr and clockwordmod is also installed , is it related with them. Is there a way to see the physicall memory from android .
thanks for the replies

yep, same for us all.

only the data partition gets counted towards internal storage memory
