so where did all the memory go?

So we got 512 rom & 512 ram. Does the OS take up 400 some odd megs? Dang I thought we'd have a ton of space left! What's eating all the mem?

Missing ram?

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.

Ram question

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.

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?

What's your maximum available ram and how to increase it?

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..
