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.

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.
Bought a 16gb card and it only has 14.8 on it, after a google search i see that they are all llike that.
Trade descriptions act?
It's the way its formatted, every hard drive you buy comes like that...they always state the unformatted capacity
For marketing 16GB = 16'000'000'000 bytes, which is usually written in small somewhere on the package, while for your system 16GB would be 16x1024x1024x1024 = 17179869184 bytes.
It's the same for every storage device, be it memory cards, hard drives, DVDs,...
I'm, sorry for being thick and a noob
can you get the full 16 out of it by re-format or is that just the final size

You're being neither thick or a noob mate.
As described by kilrah, when selling stuff they call 1GB 1,000,000,000 bytes, whereas any computer type device calls 1GB 1073741824 bytes. It's because 1KB is actually 1024 bytes, 1MB is 1024KB and 1GB is 1024MB, but in the "normal" world 1KB is 1000 bytes, 1MB is 1000KB and 1GB is 1000MB.
This always bugged me until I thought about the fact that it's actually a missuse of KB, MB & GB on the part of computers, not sellers. There's 1000 metres in a KM. There should be 1000 bytes in a KB.
In short, you can't get any extra out of it because it is the size they advertised.
thanks, you ask you learn
Can someone confirm the amount of RAM that is available to the user? There were rumors that only 512mb was available (leaving the other 512 for the laptop dock). However, I've also heard that around 800mb was available to the user (meaning the full gig, essentially). To easily see this, download Android System Info from the market, open it, and on the first page/tab you can see RAM (total available, etc.)....
Thanks in advance!
I, too, would like to know the answer to this. It would be pretty weak of Motorola if it only allowed 512 of it to be used.
+1.
I would like to know this as well.
Bump
It says 425M available + 172 if I'm not mistaken.
From android system info there is 818MB RAM available, but after killing all threads the free RAM is no more than 510MB
motoblur/android cant be gobbling up 512mb worth of RAM. perhaps some is allocated to webtop? i would be very dissapointed if that were the case.
Thanks guys
Mine says 818MB with 432 available.
Sent from my MB860 using XDA App
Bit advanced task killer only shows 394 + 111
Sent from my MB860 using XDA App
Mine says..
Max: 818MB
Free: 280MB
Maybe it allocates 512mb for webtop and when the other 512mb (or whatever size after format) runs out it starts using the 512mb from the webtop
Jesus i hope that's not true, there has to be a way to disable that.
Hey guys, those of you with the device, go into the "tasks" tab of Android System Info.....here you should be able to see EVERYTHING that is consuming memory.....in a task killer, you likely won't be able to kill everything (and you shouldn't). For example, on my inspire, there are a lot of core processes and things that wouldnt show up in a task killer (like phone, etc.). A close look in this tab should give us a clearer picture. It does, however, appear that the full gig (essentially) is available. My inspire's ram is 768 and my max ram is 623, so the atrix seems somewhat comparable in the proportion of available 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?
Hello all,
did anyone calculated memory in our Notes?
2Gb - / "system disk"
11Gb - /mnt/sdcard
But we should have 16Gb. So, 3Gb is missing. Where is it ?
When 16 GB is indicated it's never the full 16GB, the same goes for 32GB...64GB....ext, they always round up to the nearest increment. It is deceptive, but that's just how they do it with solid state memory.

Rounding ?! 13Gb <> ~16Gb

Yep. When the last time you saw increments other then 4,8,16,32,64,128...for solid state memory.
when manufactures advertise 16gb, theyre going as in 16,000,000,000Bytes. but most OS will read it in terms of binary, and the nearest number to 1000 is 1024 (i suck at phrasing).
so 16,000,000,000bytes divided by 1024bytes per kb = 15625000kb divided by 1024kb/mb = 15258.8mb divided by 1024mb/gb = 14.9 gigabytes. now subtract the 2gb for the apps partition and thats 12.9gb. now i dont know too much about the little things to do with android/linux, but i would assume that maybe 1gb or so would be reserved for the android OS itself, or some of it is used as virtual memory.
