RAM-ROM Doubt - HD2 General

i have been planning to buy a hd2, but feel let down by the launch of t-mobile version which has 576 MB ram and 1 GB rom.
all these forums are crowded with possible tweaks for getting 576MB ram.
but i wonder why isnt 1GB rom making the news? its double of what HTC offers to us.
isnt 1GB rom imporant than say 576 MB ram.
sorrry if my question sounds silly, but would be glad if someone points to me the significance of how 128 MB addiional RAM outweighs the 512 MB additional ROM.

no problem...
U can install additional programs to ROM, but u can also install them to StorageCard. As long as the sizes of the new ROMs coming will not grow up, u will always have enough storage on Rom left to install some little apps and hotfixes that needs to be installed to rom.
But more RAM means u can left more things in memory to get quicker access to them and a more responsive (faster) device...(better multitasking) for example.
Compare a Windows XP PC running with 512MB of RAM to another one running 1GB...u will feel a huge difference.
Now compare the 2 machines both with 1GB of RAM but one running a 20GB HDD and the other one a 40GB HDD, and will not feel any difference. But, if u like, u can add another HDD to the machine with only 20GB HDD (same here like Storagecard for HD2)....

Hi Bimme,
thank you for your simple explanation.
Now i also understood what it´s all about RAM and ROM.
That was very usefull.
Greetings

ya..thanks for the reply. my doubts cleared. but then this makes me ask one more question, why is it that 512 MB rom a limiting factor for win mob 7 as speculated. i mean i can get a decent capacity storage card.
i m really grateful 2 u for answeing my question, i think i will stick to and buy an hd2 this feb. but its jes these small small things that make me reconsider my option.

Or, to make it simpler, I know android can be installed to MicroSD, as a second OS. Does this mean that if our HD2 remains on 512MB ROM, and Win7 requires more, we can install it on MicroSD?
I suppose yes, but we would get in some term slower performances, on the boot, as well as starting applications, but in terms of running apps, it should stay as fast...
Correct me if I am wrong...

Another thing is that it was discovered by accident that the extra ram seems to be available on the euro devices. That caused the hype around that subject, nothing has been discovered about extra rom but that would indeed be great as well...
But yeah, as mentioned. There already was enough ram in the device so the extra ram doesn't give an enormous boost but always nice to have some unexpected extra stuff

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.
Anyone checked PagePool size ? It should be possible to free up more RAM

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.

Available RAM info

Hey guys,
I was watching a demo of this phone from the French blog Frandroid and came across some useful info about the available amount of RAM:
We know the Galaxy S has 512MB of RAM, however, being the owner of an i8000 Omnia II (only 256MB), I can tell you that there are major issues with the very low available amount of RAM the phone actually had (the people over at Modaco were fighting like crazy to bring the amount up).
- Apparently, the phone has 180MB of available RAM (the rest seems to be used by Samsung/Android and not available for apps and all that).
- The phone has 79MB of available RAM with the following apps running:
+ Email
+ Clock
+ Amazon MP3
+ Voice Recognition (from Google)
+ Browser (however I don't know if it's Web or not)
+ Social Hub
+ Video Player
+ MP3 Player
+ "Advance Task Killer Free"
I hope this helps.
Cheers,
Will

That looks pretty good to me. (I can't see what other apps i would be using with all of those running. To use GPS or read ebooks or write documents, etc I would close half of them)
Does anyone know if froyo uses more resources than eclair?
PS. I assume you mean those apps were all running simultaneously, and there was still 79MB free?
PPS. This will be my first android phone, so I hope 79MB free is pretty good. For some reason I seem to think that your post is criticizing these results, but I could be mis-reading. It is so late...
Because they are using the prototype version.
As gsmarena have stated the prototype version does only have 256 Mb while the final version will have 512 Mb

No, the prototype had 512 meg of ram, just the software wasn't reporting it correctly
There are two things to consider here: first, with 2.1, the system can't use all of the available RAM. That will have to wait until Froyo arrives. Second, Android isn't Windows! Its Multitasking is very advanced and specifically designed for mobile devices. Even if you think all these applications are currently running, and the device does its magic to let it appear so, they don't always eat their share of RAM.
Free RAM says nothing at all on Android. Even apps that aren't currently "running" are kept in Memory when they are likely to be started again soon. What use is a large sum of unused memory? If you really need it, it will be there - at other times be glad it is put to use!
That might be true but as an i8000 owner I strongly advice everybody who want to buy that phone to what still somebody realiable got the phone and can report about the total amount of ram that is aviable to the system (OS + apps).
The I8000 only has about of 139 - 156 mb ram aviable to the system besides being sold as a 256 mb device.

I think this is why the I800 was fast because "maybe" samsung came up with away to use some of the RAM space to speed up the device .
It might happen again specially while the Galaxy S looks so fast
For now let's say that Galaxy S will have 412 MB of available RAM .. still this looks too much
goood..

Galaxy S Ram and Himem........

Hi all,
I am getting this phone on July 21 when it's avaible through T-mobile. However, I ran across an issue while reading on the vast number of threads about this phone regarding the available memory.
1. Is it true the Android 2.1 is limited to 256mb of ram unless "hi-mem" is installed/enabled by the rom?
2. Is hi-mem enabled on the SGS stock rom? From my reading it doesn't appear that it's properly enabled.
3. If hi-mem isn't enabled, does that mean the SGS is functioning with only 1/2 of it's ram?
4. If so, how much free ram is showing on the stock rom and how much should we see once hi-mem is enabled?
I'm assuming that since many Android phones come with 512mb of ram these days, that hi-mem has been properly enabled on some of them. How much free ram does a typical android phone running 2.1 or 2.2 have after bootup?
I'm currently using a Touch Pro 2 which runs out memory all the time and would rather not have to deal with that on Android as well. I assumed that 512mb is supposedly to be more than enough to run 10+ programs at the same time should I choose to.
Thanks in advance.
It doesn't appear to be using 512MB I only ever have around 100 meg free. I used to have a touch hd and know what you must be thinking but i can assure you even with only 256 available it is fast and hasn't run out of memory on me yet. be sure to download a memory freeing app like task killer.
It runs quake3, something i could never get my hd to do with out practically killing the os
Kernel supports 512M RAM.
with the new Gingerbread specs it REQUIRES 512MB .. now if its 256MB , that's something to worry about

Don't worry, it has 512mb. It's just that some older kernels didn't support more than 256mb of ram, so the phone simply didn't "see" all 512mb.
My concern was that the kernel out of the box was too old to support the full amount.
The phone physically has 512MB of RAM. However, I think Android 2.1 is limiting the availability to 256MB.
Froyo 2.2 will correct this issue.

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.

It's also strange that hard drive manufacturers advertise a "500GB" hard drive when you really only get about 465GB of actual usable space.
Same concept. Froyo may be able to utilize more RAM than Eclair but you'll never get the full "512MB"

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.

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.

There's no way in hell the Radio, hardware addressing space and/or GPU frame buffer use 170-180mb of the ram.

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.

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?
