Meminfo ?

I may be missing something, but on my Nexus One, doing `cat /proc/meminfo` shows Memtotal: 217812 kB
Huh? I thought this phone had 512 MB

it does. alot of the ram is reserved for the Android OS. Similarly, the mytouch 3G had 192MB RAM but only 97MB were usable by Applications.

That's a lot of reserved ram, Odd that my friend's Droid shows MemTotal: 230860 kB
Can you confirm that my value is correct for the Nexus One? I want to be sure before I root and void the warranty (In case of bad RAM)

its correct, theres been at least 2 other threads about this. also if you had bad ram you wouldnt be seeing a lower amount of ram, you simply would experience alot of crashes (assuming the phone even started up)

I apologize for the duplicate thread. Seems my searching skills are not up to par....
Thanks for your help.

xperia x10 hardware ram

i heared that the x10 only have 256 mb ram , and the asian version is the version who has 384 ,not the worldwide version ,so what is the truth

Well, gsm arena has 384Mb in their spec list.
Unfortunately android 1.6 can "see" only 256Mb so, no idea how much really has.
We will know for sure when we will get android 2.1.
Also at that point we will know if the display has 16mil colors or only 65k

I'm also curious to know howmuch RAM does that beast actually have. Somewhere I read that only the Japanese X10 from DOCOMO has 384 Mb RAM

The japanese version runs android 1.6 but still has 384 mb ram.
but the x10i and X10a versions are said to have only 256 mb ram. may be SE has locked some ram in the x10i and the X10a just like Htc did for the leo european version.

this nearly 384

256MB RAM
128MB video memory or VRAM

i mentioned it b4
here
&
here

And how much ram the Nexus One has? 512mb all for the system?
IMO the ram is VERY important, and if the X10 only has 256mb for the system and the HTC Desire or de N1 has the double (n1) or more (HTC desire) i think i will make the change...

Don't clog up the dev forums with this stuff this is exactly what general Is for

Nexus one has a full 512 for system. I also thought the x10 has 384 as mentioned by gsmarena. Might return mine for an acer liquid e now

Only a mod can move the thread can't they?
Since its not moved yet - I've done a test with my X10i.
Using the system panel app with 51% of memory used there is (49% left of course) 130.2MB available, so there must be at least 260.4MB free to the user, and there is a lot used by the system too.
130.2/49 = 1% of user available ram = 2.657 MB (to 3 decimal places)
2.657MB x 100 = approximately 100% of user available ram = 265.7MB
265.7MB is more than 256MB of ram without system memory added to the total.
With my old t-mobile pulse which had 192MB of ram, only 90-something MB was available to the user, with 102 used by system etc.
So there is probably 384MB of ram in all X10's.
EDIT:

the X10i look like have 384Mb RAM, but it's not detailled :
http://www.gsmarena.com/sony_ericsson_xperia_x10-2964.php
The Nexus One have 512 Mb, not detailled too :
http://www.gsmarena.com/htc_google_nexus_one-3069.php
But the X10 is look better than Nexus1 in fact... better Photos, better Videos, better pretty... speed look a little bit the same... perhaps more slowly with much applications executed at the same time..
In France, the Nexus1 is cheaper than X10, but i decide to buy the X10... more design, better photos, Videos, ....
I use to have an iPhone 3G, photos and videos are really poor... but applications are really GOOD... but i'm not a player...

MOD EDIT - Moved to general forum as not related to android development

Apparently the donut limits the ram so once an upgrade appears we'll have it all

Sorry, that I post in an old topic...
Android system info and Quadrant are showing 280MB RAM. Quadrant shows also 100MB unused, it's not the free RAM, I had 50MB RAM free when I locked at it, so my question is:
Can we activate these 100MB somehow? That would help big games and when a lot of apps are running simultaneous...

only if you crack bootloader.

Htc hd mini only 256 RAM??

true or false?..all aplications show about 256 ram and all the time memory usage is about 70 % who can suggest something?

its 297 corectly... check yourselves...

And in fact it is 384. But the 87MB that you can't see are used for PagePool, radio and so much more

576 mb and Leo_RADIO_2.12.50.02_2

This is the best radio for me, tha latest has bad signal reception.
Typing free on terminal reveals 423816 RAM
Subtracting 128mb out of 576mb gives a greater number.
From what I have read, only the latest radio gives 576mb, so what can I do?

It all depends whether you (or the system) are displaying 'the number of megabytes available' or actual megabytes.
The discrepancy comes from 1 Meg being 1024 k,, 576 Meg should be seen by the system as 589824 kilobytes, but rather than give you free memory manufacturers sometimes actually give you 576000 kilobytes which converts to 562.5 Meg, but they can say '576 meg' because we all know that a thousand kilosomethings are a megasomething, so 576000 kilophants is obviously 576 megaphants, right? course! not.
Also, the way it is displayed to you makes a difference, because one app may say 'you have 100 megabytes free' whilst the next program says 'Free RAM 102.4MB'
both are correct and the same, 100megabytes = 102400KB = 102.4MB (but not really 102.4MB, thats just maths taking 102400 kilo and turning into mega, , its wrong, but it happens a lot when a display converts a large number into less digits, )
Hard disk manufacturers do something similar, when you buy a 1gig hard disk you actually get 1000 x 1000KB which is 976.5MB, or less often 1000 x 1024 = 1000MB but we THINK we are buying 1024 x 1024 kilobytes to give 1048.5MB, or 1 actual real gigabyte.
Also, your current radio should unlock the ram so long as the rom is compatible.
Your figure of 423816 ram converts to 413MB, and my phone shows '412MB ram', which is as close as i need.
Im sure ive made some glaring maths slip up there (im a little ston,,err distracted, , but the point is you never really know if you are looking at real megabytes or marketing megabytes, or mathematical megabytes, so figures around what you expect are generally ok.

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?
