Atom Life memory capacity - iPAQ rw6828, XDA Atom General

According to the spec. of Atom Life, ROM/RAM should be 1GB/64MB.
But actually on the system it shows, 795.28/48.36MB.
Anybody know why it's so much diffrent from spec.?

I don't have a Life myself <snicker>, but the same thing happens on the Exec.
It's rated to have 128MB/64MB ROM/RAM but it comes out as 98.26MB and 49.89MB respectively. I don't get this either. Could someone explain?
I was trying to compute it with the idea that 1MB = 1,048,576 bytes but it doesn't work.

Actually, atom exec is rated to have 192MB ROM. A part of it is used to store the OS

Ah, I see.
Well I can see the OS (or parts of it) stored on the accessible part 98MB part (when I go into the Windows directory), so I take it the "non-accessible" part is where the back up of the OS is stored? The one that you can restore from when you do a hard reset?
And are you sure it's 192MB ROM? That means WinCE 5 takes up like 100MBs?!

HTC & MS are Cruel & Manipulative!I know u visit thi

The new Dell Axim X51v has 256MB RAM on WM5.0. Why the hell didn't the 'Worlds' Most Powerful fu..ing phone' get this? :evil:
HTC..you are are truly wicked!!! :evil:
You build the Dell Axim don't you? :? Microsoft..you test your software don't you? Stupid question.. you obviously don't, but are quick to charge for incomplete and unpolished software. In contrast you are quick to prosecute people who actually copy your buggy software.
HTC...how can you make new geneeration devices with under-powered bits? 64 MB RAM? C'mon!! Couldn't you have at least given us 128MB RAM so we don't all worry about memory management? Are you listening? Aaarrghh... who cares right :evil: ??!!??
I can't make up my mind if the Universal is an excellent technological achievement or an overpriced, overhyped piece of poorely stiched together meta-technologies. :roll:
So now, I have to learn to become a technology guru, not because I want to, just so I can use my bloody phone. :x
I give up.
No need to have a fit mate!
You've got your numbers mixed up. The Dell Axim has 256MB of ROM, and in fact has 64MB of RAM (same as the Universal).
Windows Mobile 5 introduced persistant storage which basically means everything is stored in ROM, rather than RAM as with WM2003. This means you now have the full amount of RAM available to you, and 64MB is loads!
There's also the issue that if you double the RAM size you double the memory power requirements which affects battery life.
Take a look at this article which explains it all a lot better than I can, and you'll see it's actually a really good idea to have 64MB:

Persistant Storage
no: 1
Thank you for your informative reply & I found the provided link very useful too. Well, they should have still given us at least what the Dell has got. Except for the keyboard and phone, we've not got much more and we pay more than double! Anyway, thanks again.
I'll discuss these issues with my shrink at our next meeting, I just can't control myself.
What is in the Dell vs. other PDA's that HTC makes is not really something that is comparable. Dell pays HTC for making the Axims. I imagine that if Dell is willing to spend the money on higher specs, they can do that. HTC doesn't decide what's in the Dell Axim, Dell does (for the most part). HTC then engineers and builds the devices.
On the other hand, HTC makes the JasJar for i-mate. i-mate decides the specs they want (with some input from the phoner companies I'm sure) and they pay HTC to make their PDA's. So, just because HTC makes the PDA's doesn't mean they are all going to be same spec-minded or the same cost. It's up to the "brand" (HP, Dell, i-mate etc) what HTC makes for them.
As far as deciding whether the Universal is an excellent technological achievement or an overpriced, overhyped piece of poorly stiched together meta-technologies, it's a little bit of both. It is an excellent technological achievement AND it is overpriced

The motherboard and software was designed
for 128MB RAM, but they put only 64MB into
Universal. Saves THEM money and reduces
power consumption.

It's a big shame!!!
They promised us heaven, and I find myself in hell!!
This device is a dream, but without minimum 128MB, better 256 MB of RAM, becomes hell, and useless!!!!!! :twisted: :twisted: :twisted: :evil: :evil:
256Mb of Ram?
I have a (old) pentium 4 laptop that works well enough with 256Mb of Ram. Doesn't that seem a bit excessive for a PPC, especially as your battery would only last for about 93 seconds?!
As i said, 128mb, or 256 MB, do you have a JasJar? Do you know how it feels, to spend 1.094 euro plus 174 for and SD card ultra speed 2 GB, an not being able to use it at all, with the very simple applications? My Treo 650 runs much better!!!
And then, I shouldn't cry for at least 128 MB??? :twisted:
@trendstyle,
Sell the device.
Anyways, what is it that the 64MB RAM of the JJ does not permit you to do? Why on earth would you need 128MB of RAM? I multi-task extensively with the device and yet face no memory errors. Are you trying to run Photoshop or something like that on your device?
As another forum member has rightly pointed out, what on earth would you need 256Mb RAM for??? It wouldn't even last those 93 seconds!!!
Word of advice to other people who want to crib about the device. Before you start getting all nutty about spending this much and that much on a device, do a thorough research or wait for some reviews. You will save yourself and others the agony and disappointment.
My 0.002.
I entirely agree with Universaldoc.
While listening to the media player and running two processor and memory intensive applications Planmaker and TextMaker simultaneously I still have 10MB of RAM to spare. Why do I need more RAM. I am to use my JJ practically and not to see what amount of applications I need to open simultaneously to kill the JJ. More RAM is technically possible. But do I need it at the expense of battery life. A big "NO" for me at least.
Regards
Do you?
10 Mb are enough?
There are some games, that requires 15 MB of free RAM!!
And in a super top device, this should be acceptable???
Give a look here....

I change a mobile phone every 4 months, buying always what is the top of the technology...
And believe me, at the moment, jasjar doesn't deliver what I-mate promised...
I look forward to a new rom, solving memory problems!
A new rom that came with 256mb memory with it, now there's something....
The universal is a good device and memory is fine on it you can have loads of apps running and it still runs faultlessly. This is not a lap top, if you ned one of those buy one nor is this a mobile it's a great device that tries to accomodate both, sure it could have more memory but then you'd be *****ing that " it's primarily a phone, why is the battery life so bad, it runs out half way through the day and i miss loads of important calls"

Yes, I do thanks, and if you "can't use it at all, with the very simple applications" then I'd suggest there's something actually, properly, really, honestly, very wrong with yours?! (Especially if your Treo 650 runs much better)
I know people are now used to computing with 3Ghz AMD64's with 1Gig RAM, and 100's of Gigs of HD space, but let's be realistic here, for a device of it's size, it's fantastic.
Given 128Mb RAM, I'm sure some people would only move on to bemoaning the fact that it 'only' runs at 520Mhz, it 'only' has 128Mb Rom, it 'only' has 802.11b, it's 'only' got 1.3 megapixels, etc, etc, etc.
The JasJar is not perfect, and there's a thread in this forum where people are already posting their JasJar 2 wishlists, but in my personal opinion (and I'm sure many agree), it's currently the best PDA/Phone available, it has near flawless performance for my purposes, and I for one am more than happy with it.

Concerning this, I have a Dell Inspiron, 9300( a laptop), 2.14GHz Centrino Sonoma(equivalent to a Pentium 4, 3,8 Ghz), with 2 GB of ram, and Nvidia 6800 go with 256MB of video memory,I like my tech stuff to be the top, and this is why I bought right away the Jasjar, as all the review I read on the web they were screaming it was great!
My Inspiron is great, Jasjar, not at the moment...
In my point of view I assume 64 RAM are enough but if we had a big DOC storage well lets say about 256 MB this could be something for us, but the facts and the sad parts, which it's the 128MB of DOC :evil: !!!
I was reading the Universal hardware specs, we could upgrade the DOC to a bigger size!!! But we need a hardware techy to solder it.

More RAM for G1, possible???

do you know how windows vista can use external memory and make it into additional RAM? well can the G1 be programed to take memory from the SD-Card and turn it into more RAM?? I know that it might not work but its worth a check!
IF your not sure about it check this it will explain ((http://articles.techrepublic.com.com/5100-10878_11-6039379.html))
I believe you're thinking of Swap - check out http://forum.xda-developers.com/showthread.php?t=531988
Also don't forget using your SD card as swap partition will thrash it and could shorten the life of your SD card due to alot of writes.
If you really want to do this look for a program called 'swapper'.
oh ok thanks for the heads up !

This is pretty much the function the swap file provides. There is a differentiation on a desktop because on a desktop files are stored on a hdd, whereas a portable device usually uses flash as its storage and swap.
And just to clarify, Vista readyboost is completely different to RAM or swap partitions.
Flash memory is limited to a certain number of writes, it is a very large number so in normal use you will probably never hit it. Reading however will not affect the lifetime of your flash memory.
Hard drives do not have any such limits.
Readyboost uses an SD/USB memory card/stick as a cache to quickly load frequently used files, this is because it's generally faster to read from flash memory than from the hard disk. Readyboost DOES NOT write very often, this is why it is suitable for use with flash memory.
Swap/Paging/Virtual memory is completely different, it is an area on a disk, a file on windows or a seperate partition on linux, where the operating system can dump some of the data that is in RAM if it runs out of space. If you have low RAM or are using high memory applications this will do alot of reading AND writing, therefore will reduce the lifetime of your flash memory. This is why swap partitions are normally on hard disks.
Hope this helps explain it!

Sure they do. Just considerably longer. Also, hard disks, for quite a long time now, have been capable of dynamically remapping around worn out sections and come with a decent chunk of unused space that is used for remapping. Hard disks also suffer from gradual demagnetization -- over time, the differing magnetic fields on the platter will interact with each other, causing data loss. You can generally expect a finite life time of any hard disk before large sections of the platter become unusable. I have noticed this particularly to be the case with winvista, which by default likes to catalog and recatalog your disk (they say for fast searching), but the end result is writing and rewriting of the same small portion of the disk, which causes it to wear out VERY quickly, though leaving the balance of the disk perfectly functional.
there might be a way to physically remove (with a soldering iron) the 192MB ram chip, and solder on a 288MB ram chip like those on the newer HTC phones.
I really want more RAM, but I also want a keyboard. and with Android, you can't have both right now
That would be an impressive waste of time and energy but kudos if you could manage that. Best bet would be to buy the Hero when it comes out and get a bluetooth keyboard.

Does hero even work on tmob 3g in the US? Looks like its geared for at&t.
I'd say replace the memory chip if you can and report back!
I would definitely try it (I'm an Electrical Engineer, and solder at work all the time)
But i'd rather buy a 288MB chip from somewhere, rather than rip it from a different device.
I don't wanna throw away money.
if someone knows a supplier for those chips let me know and I'll try it and post screenshots
The last 2 smartphones I have owned there has been a discussion on upgrading the memory with huge threads and a few people trying. The end result has always been it is by far cheaper to get a new phone in another year which will have a faster processor, more memory, more storage etc...
Sure it can be done but with how fast technology changes it probably isn't worth it.
So is HTC HERO worth buying for more RAM and speed??
Only if the HTC Magic also is, because they're exactly the same except for the shape of the plastic.
I wouldn't give up the keyboard.

the htc magic isn't exactly the same. Some htc magic models (like google ion and tmobile mytouch) only have 192megs of RAM.
My understanding is that apps are limitted to 16mb of ram anyway. The real problem is the data rate of the ram. Some have hinted that a class 6 sd card is just as fast at read/write as the phone's ram. So more ram in theory won't really help if it's still limmited by read/write rate speed. More internal memory would be nice but again won't make the phone any faster, just help with our 'out of room for apps issue'.
Perhaps on the hero motherboard buss speeds themselves are faster but I doubt there's much we could to speed up the dream :/ someone please correct me if I'm wrong tho..
You are probably confusing internal FLASH with RAM. A class 6 uSD card is NOWHERE NEAR the speed of the ram. The RAM is orders of magnitude faster.

Reminds me of the days when people soldered on extra RAM on the XBOX1 to increase performance when using XBOX Media Center!
I thought there was a technical manual out for the G1 somewhere that listed parts... Not just the service manual which showed you how to open the device for repair. Could be worth running a decent google search for the motherboard and parts and then find a supplier for the RAM if you're game in trying to solder more on.
Thanks to the flexibility of Android as well, I'm pretty sure it would be able to read and make use of the extra RAM too.

Memory Difference?

I do not understand why the Toshiba Tg01 uses so much more memory than my HTC Diamond with Windows Mobile 6.5.3 and Sense 2.1? Why does the Toshiba use so much more?
I think Toshiba is not suitable for Sense like HTC devices, RAM is still our mostly problem. Maybe Win 6.5.3 is more stable for Sense.
been thinking the same thing since i got the phone... can think of about 3 possibilities...
1)bad optimization in toshiba additions
2)the ram in locked out and shows up as used to make us buy their newer models...
3)the phone has actually less ram and and its ram information is faked...
but thats just me...
Memory Usage does not add up
I used Memaid to check the running processes and they added up to only 41 MB. If the total is 205.1 and the processes running are only 41 MB where is the other Program memory allocated to?

Filesystem mirrored from ROM to speed up the device. That's a common use on WM devices, but has some counter effects. With 100Mb free RAM, you have almost all you need, but with just 30Mb, things become a little more complicated. Toshiba setted up RAM in order to preload files and packages from the OS into the RAM. That's my thinks arround it. Maybe the true history is another one.
is the worst thing at tg01.
i bought a phone with 256MB ram not with 100MB. i expected a healthy 150Mb free not 60Mb.
I had no other bad experiences with it except bad quality with orange robot chick. The funny thing is that the Vodafone robot is (almost) crystal clear.

The size of Pagepool is 15Mb. Maybe we can set it to 6-8Mb, but would 7-9Mb be worth of it? :S
If we can find 2-3 methods to gain 7-9Mb, a 24Mb more free would be awsome. But just 7-9 won't make a true diference.
I've checked this myself but it looks odd to me when I see 15mb PP size... so it's not PP fault... When I'll have more time I will take a look into dumped rom maybe I'll find what takes so much memmory ...
Hi all,
I understand our TG01's constantly show a low amount of free Ram but can honestly say i have never experienced any slow downs or Programs shutting down on me. Since the last update with the Radio fix mine runs great it's fast responsive and i really have no issues since changing back to the Windows Classic lock even playing Music over Bluetooth in CorePlayer is perfect with no more annoying cut outs.
At one point i was going to replace my TG01 with a HD2 but since the last update and all the fixes it brought i just can't see this as being worthwhile. I even tried one of the new Roms with Sense 2.5 only to discover as much as i really like the Weather app in Sense i actually prefer SPB Mobile shell with the Espresso theme over Sense.
The TG01 may not be perfect after all what device is but for me now it gets pretty close, i still think the screen is if not the best one of the best out there. I also love the fact that even with a 4.1" screen it's only 9.9mm thin and not exactly heavy either it does all i want with ease my Music sounds great and my unconverted DivX files play and look stunning on it's screen as does Web browsing using Opera.
Having had the TG01 since launch i have been looking at an upgrade as have one due from VodaFone but honestly can't see anything that can replace my TG01 and offer anything more or better. Of course i wish we hadn't had any initial issues and the fixes would of come quicker but i still think the TG01 is a great device and one that hasn't really been surpassed yet.

326MB of RAM?

Just got a Samsung Vibrant.
I noticed the phone says I only have 326MB of total RAM. I thought this phone was suppose to have 512MB of RAM? Is 326MB normal or did I get an odd phone?
No that's right. It's all the kernel will allow us to use. Even with the unofficial froyo roms out, we only get 341mb.
Friends don't let friends flash drunk...
Cool. Thank you for the information.

I would say it is more like on your PC. You may have 4 GB installed, but when you look at it it will tell you you have only access to 3.5 GB because other hardware is using the memory, like a shared GPU etc.

I'm getting tired of people making these retarded f****ng comparisons. Hard Drive capacities go down due to formating. Also, a 1 byte file takes up the smallest allocation unit on the drive, so space is wasted there as well. Better file systems are better about it, but unless you're writing raw data to the hard drive there's no way to avoid formatting it and losing space or writing data to it and losing space due to allocation boundaries. I've never heard of anyone Formatting RAM, have you? If the smallest allocation unit on the HDD is 4KB, then a 1Byte file will really take up 4KB on the drive's FS.
RAM is totally different. If there is 512 RAM there's 512 RAM. The only time you will see less than your amount of RAM on a computer is if the computer is allocatting a certain amount of RAM for use by an integrated graphics card (or something else).
Problem with our phones is that they're set up like the latter.
We don't have 512 RAM. We never have, and we never will. We haev 340'ish and the rest is GPU RAM. You're never going to run general applications on that RAM.
Oh. I had edited my reply because I had assumed I found my answer from this...
developer.android.com/sdk/android-2.2-highlights.html
"HIGHMEM support for RAM >256MB"
I had assumed that mean the official Froyo when we got it would have 512MB available.
So I guess I misunderstood their meaning there. So the 326MB is pretty much the max my applications will have to work with on this phone?
I guess I'm puzzled because I was in T-Mobile a couple days ago and I was going back and forth between getting this Vibrant and the MyTouch 4G. The MyTouch 4G advertises 768MB of RAM, while the Vibrant advertises 512MB of RAM.
So now I'm back to my original confusion. Why would HTC put 768MB of RAM in the MyTouch 4G if Android can't even use 512MB? *confused*
Ya'll compared it to the Windows XP limitation with only seeing 3.2-ish GB of RAM. But Dell doesn't install 8GB of RAM in Windows XP computers either. I guess I could maybe understand the 512MB phones if some of the memory is going towards video. But the 768MB phone doesn't make sense then.
This is my first Android device, so I'm still trying to figure out these things. Sorry for the dumb questions.

Oh. I had edited my reply because I had assumed I found my answer from this...
developer.android.com/sdk/android-2.2-highlights.html
"HIGHMEM support for RAM >256MB"
I had assumed that mean the official Froyo when we got it would have 512MB available.
So I guess I misunderstood their meaning there. So the 326MB is pretty much the max my applications will have to work with on this phone?
I guess I'm puzzled because I was in T-Mobile a couple days ago and I was going back and forth between getting this Vibrant and the MyTouch 4G. The MyTouch 4G advertises 768MB of RAM, while the Vibrant advertises 512MB of RAM.
So now I'm back to my original confusion. Why would HTC put 768MB of RAM in the MyTouch 4G if Android can't even use 512MB? *confused*
Ya'll compared it to the Windows XP limitation with only seeing 3.2-ish GB of RAM. But Dell doesn't install 8GB of RAM in Windows XP computers either. I guess I could maybe understand the 512MB phones if some of the memory is going towards video. But the 768MB phone doesn't make sense then.

First of all. There are no dumb question. Second. Android uses all of the RAM. But as the phone reserves memory for hardware and other system essential services, you will only be able to use a certain amount of the memory. In this case around 345 out of the 512. The rest is put away so that the OS can run stable etc.
So for the MyTouch 4G it says that there is 768 MB installed, but you won't see all of that. The phone will reserve certain amount for it's hardware and you will never be able to free it unless you know how to change the kernel.
Hope this clears any confusion up.

for xp, the memory limitation is due to 32bit memory addressing. 32bits can address a theoretical 4gb, however due to also addressing gpu memory and probably some other reasons xp can't address the entire 4gb and so you see 3.xGB.
i can't really speak to android or the vibrant, but i'm guessing (like others have said) we are losing some of our ram in a share with the gpu.
I think most people are missing the issue here.
The phones are advertised as having 512 MB RAM.
When you buy a computer, and it says 512, it comes with 512 (only exception is the one I stated - integrated graphics cards sharing system RAM - but that is usually listed on the Computer Spec sheet).
So, when they get a phone and it says 512 MB RAM, they expect for there to be 512 Application-accessible RAM on the device.
HTC adds more RAM to put the user closer to the advertised specs. Most other manufacturers do not.
So users end up with 326 MB RAM wondering if they got what they paid for.
Which... they really didn't if you use you common sense, but companies will always use technicalities tand semantics o defend their decisions and/or actions.

I completely agree with you. In fact some of us in xda have discovered that sgs indeed has less than 512MB of RAM. We are still somehow trying to defend Samsung by say Galaxy TAB has more RAM (when Samsung advertise 512MB only for TAB)!
On a side note - Hard Drive capacity is measured in millions of bytes hence 500,000millionbytes
will be around 465GB only (unformated)!

I doubt ~170 mb is being allocated for the radio and for hardware addressing space. It's my opinion that the phone actually only comes with 384mb ram.

Many do list that but what makes the drives smaller is formatting. The raw size is what it is, but the formatted capacity is much less. You can ser this on sf cards easily. Format it as fat32 then ntfs, and the end (formatted) capacities will be different. Then play with allocation sizes as well ;p
If you have hordes of small files it can really eat inyo the space on ut hard drive, as well, since a file can only be as small as the smallest cluster size in the filesystem.
Even if they made the drive 1024mb x however many gb they say it is, that will be instantly cut fown tje minute you format a fs onto the drive. There is also space the fs reserves for system use, as well. Mft and such.

He's right hardware addrrssimg shouldn't need that much, and graphics in a phone shouldn't need that much either. Maybe so,eone should sue Samsumg for false advertisement and see what they say.

You can "no." all you want, but unless you have proof to the contrary, I'm going to stick with my OPINION that the phone has 384mb.
There's no way in hell the Radio, hardware addressing space and/or GPU frame buffer use 170-180mb of the ram.

I agree just checked and vibrant shows similar ram to htc aria, which has 384mb ram stock.

There is a thread in the i9k forum that details the amounts of ram reserved in the kernel source. Just about every feature on the phone has dedicated ram, weather or not it's currently in use. That plus what the kernel shows as available adds up to 512mb. It's stupid, but that's how it is. Poor and lazy software engineering, IMO. Unfortunately, doing the allocation in a sane way and having it work in android properly is very difficult without all of the source, which we will probably never have.
It's not really any better with other manufacturers. They all do it. I think they ought to be required to disclose user available ram amounts, but nobody cares what I think.

I'm getting tired of people making these retarded f****ng comparisons. Hard Drive capacities go down due to formating. Also, a 1 byte file takes up the smallest allocation unit on the drive, so space is wasted there as well. Better file systems are better about it, but unless you're writing raw data to the hard drive there's no way to avoid formatting it and losing space or writing data to it and losing space due to allocation boundaries. I've never heard of anyone Formatting RAM, have you? If the smallest allocation unit on the HDD is 4KB, then a 1Byte file will really take up 4KB on the drive's FS.
RAM is totally different. If there is 512 RAM there's 512 RAM. The only time you will see less than your amount of RAM on a computer is if the computer is allocatting a certain amount of RAM for use by an integrated graphics card (or something else).
Problem with our phones is that they're set up like the latter.
We don't have 512 RAM. We never have, and we never will. We haev 340'ish and the rest is GPU RAM. You're never going to run general applications on that RAM.

I had 326 RAM .After installation of FROYO 2.2,my Galaxy can see only 304 RAm.Why?I expected to get more RAM with FROYO 2.2 Why did this happened?

Maybe you should do it. You know, since you know exactly what you're talking about.

So 2GB RAM are only 1,8 GB, Sony uses its own values for marketing and counting?

Just seen that.
They advertise the compact as a 2GB RAM device, knowing that they only deliver 1,8 GB.
Anyone else seen that before?
I do not think it s a way to free up to full 2GB as advertised?
Other brands deliver 2GB if they tell their devices have, why not so z5 compact?

Where's the source on what you're talking about? The RAM is always going to be used up by something - the OS, launcher, etc. You're not going to turn the phone on and have exactly 2GB of RAM available.
Sure, but it says 1,4 out of 1,8 used, 3xx free.
That means Limit is 1,8 as shown under Memory, not 2 as advertised. Never noticed that on a phone before.
As soon as the device is running memory is used, but it should say out of 2,0 not 1,8?

https://en.wikipedia.org/wiki/Timeline_of_binary_prefixes
Also - not sure why you'd want to specifically blame Sony for this
Coming from the technical, developer background:
you have to consider that device drivers also eat up quite some memory/storage (best example: the Galaxy S, GT-i9000: 512 MB advertised, at best 300 [384 at best] available)
it's only the device drivers, it's the kernel (system) itself that also needs memory
so you'd basically have to advertise e.g. 2 GB but plug in 3 or even 4 GB to have full access for e.g. apps
All companies define a gigabyte to be 1000MB, and a megabyte to be 1000kb, etc etc. In reality it's 1024KB per MB, and 1024MB per GB.
You never fully get 2GB, just check your computer eg. your hardrive might be 1tb big, but in reality its only somewhat over 900gb? 16gb ram might only be 15.9 gb!
Well, nice, not sure since when vienna is germany?

derailing the topic like a pro
Home Country vs. Service Provider vs. City
you'd know that if you had taken a look at your own profile
(I moved back some time ago)
Thanks for the notice though
The topic is...that in Windows the full RAM without any convertings of bits and bytes is shown.
Only Hard Disks have that "exchange" from 2TB to 1,8 e.g.
So I was not awaiting that on mobile RAM too.
Really ?
I gotta take a look next time I booted into Windows,
Android sort of is Unix, Linux - so that is more to be expected
yep
BIOS: 3096MB a 4GB Bar
Windows too
But I got an explanation somewhere else as smartphones use flash memorys equal to SSDs so its the same 1000 isnt 1024...thing there )

3096MB ?
that looks more like a 32bit OS limitation though

Plus, on android some ram is reserved by GPU. Unlike dedicated graphic card on PC/Mac which got their owned ram but our GPU shared with system memory.
Same thing as onboard GPU on desktop systems so?
Well 3096 per slot, using several 4GB bars, no 32 bit limitation)
