i8000 has 256mb of ram... but where is it?

When I check the amount of free ram after I start my Omnia II it shows that I have somewhere around 70mb free, with half of the ram showing as "reserved".
I feel like I was cheated into buying a device which only has half the advertised amount of ram. Sure, it might be there... somewhere... but why can't we have it? Why is half of the ram "reserved" and what is the purpose of this exactly? Is there anyway to set it free?

it is possible that Samsung reserved it for Touch Wiz or samsung apps included in Rom?

Hi guys! I have the same problem. Over half RAM Memory is "reserved". I hope somebody can help us in getting more available RAM. Thanks!

"Sorg" over at modaco has determined that approx 100 is reserved for the radio, camera and hardware accelerated graphics.
currently the page pool is aprox 20 mb but the newest release from "secany" over at modaco has Samsung reducing the page pool to 15 mb to give us an extra 5 mb of ram.

maybe omnia II case is similar to the HD2 case where some geek find out how to increase RAM memory... seems that HD2 also had reserved memory for ie. radio and other functionalities and it was solved how to release it.. don't know the case in details but read over net that someone did that creating new kind of rom.

i hope xda devs can fix this issue. This is one big issue why the omnia is not so great if this gets solved then all the problems would go away. I would glady give up some space from my storage if need to et maybe 128MB free. after a cold boot i get around 60MB free thats with spb and mskip both running

Rom and Ram(random access memory) are two diff things, you cant give up internal mem as ram.

We hope one day our brother inside xda dev or modaco can create the Tools & ROM to reFormat the RAM and Hidden Store in My Storage, so we can get more storage with workable ROM, tq

Omnia 2 has 256 MB RAM as per tech spes, but only ~140 is usable, the rest remain for radio etc. so maybe this remaining ~100 MB could be accessible somehow as on HD2

if camera has reserved ram then why does it have to shutdown everything else or complains about the memory and won't start :s

good question. Anybody knows how it works or how it is supposed to work?

64mb - radio (radio chipset has no ram so it uses system mem)
36mb - os crap(pagepool,etc..)
16mb - graphics mem
256-64-36-16=140mb available to wm

64mb for the radio is... kinda too much. Seriously, what does it need that much RAM for?

easiest way to solve it is to go back to 6.1 rom you get aprox 110-120 mb of free ram. theres a few on modaco.
Or personaly i find if i use titanium + disable lock screen(usetouchlockpro), diable default dialer(use PhonEx for dialer/contacts) you get 90 mb after boot. which settles down to aprox 80-85.
This is useing Sonblack rom from PDAViet
it can be found at PDAViet or Modaco!

Not true, my one is 6.1 and yet less than 25m I can use this space even though so call factory default after reset. The bloody main storage has 512m, almost 500m has been used. I have not install any program yet. The 8G is used about 0.6G which wasted so much space. Samsung designers really screwed up!
Looks like even thought upgrade to 6.5 also did not improve much of the main storage space, that really sad..

I was shocked by these amounts of free memory too.
I was found only ONE solution...FLASHING some LITE or ULITE (Ultra LITE) ROM.
I personally flashed rom by Speedfrog: http://windows.modaco.com/topic/323437-lite-roms-by-speedfrog/
Free main memory about 300MB and free Ram about 110MB...I'm using it for more than one year with great success.

is it really advatage with hacked RAM size?

hi all,
it seems no change in speed by using 576MB hacked instead of original 488Mb (for my personal experience after using 2 cooked roms).
Can anyone help to give me more info for this such as advantage/disadvantage for these size and will it harm system or not?
Actually, it just happy me with bigger free size of ~300mb
thanks

This issue could also have other reasons.
Imagine you have a car
On the speedometer max speed is 200 km / h
Now you build a speedometer with a top speed 300 km / h
each now looks in the car assumes
that you have a tuned car which goes really fast

WM apps usually consume something between 0.2 (Outlook) to 10MB of memory (TomTom), so having 200MB free is more than enough for some serious multitasking. So, it is definitely not needed, but does not make any harm either.

I don´t agree, I had a Diamond with 192 mb ram and a touch HD with 288 mb ram, and both just powered, the HD was a lot faster, just because of the 100 mb extra ram (both had more than 50% ram free)

extra ram wont make the machine faster per say... it just increases the ability to handle more

If there was no advantage, then HTC would have probably not reales a HD2 with twice the amount of memory as the first release.

as johnc says... they havent done that.
What they did do is release the T-Mobile Us version with twice as much ROM.
nothing to do with RAM. get your facts straight.
The T-Mobile US version however does have an extra 128MB RAM. But like i said above... there is no increase in overall performance. Extra RAM simply means it is able to handle more multitasking.

i think this is the best answer. Yes, it just bring us the feeling.
some of you misunderstand my question. Of course, bigger ram size is surely faster but in this case, it is just a tweak from original 488Mb (hardware) up to 567Mb (fake ram )

It requires a tweak to 'unlock' the extra RAM as it has been 'hidden' by the ROM software.

a tweak or change the rom

From the technical point of view. When an application is started the operating system loads the application from the ROM into the RAM memory, this process is slow because ROM memory is slower to read than RAM memory. So in order to take full advantage of the CPU 1GHZ processor, the operating system needs enough RAM memory to load the full application. RAM memory sits right on top of the CPU and communication between the CPU and RAM is very fast. If there isn't enough RAM memory the operating system will load part of the application into RAM and the rest will remain on the ROM. This will make the operating system to constantly read ROM memory which slows down your application. In some cases when an application is stopped the operating system might not release corresponding RAM memory, this is called a LEAKING POINTER. In this case you will need to reboot your system to release the memory. Having too many LEAKING POINTER will make your phone run slower because operating system constantly has to go to the ROM memory instead of using the full potential of the RAM

lol...
Nearly as funny as RAMAROM!
With over 448MB of RAM, I really doubt that any WM app is going to cause problems with memory leaks to the extent that an app cannot run properly. Bear in mind that WM apps are tiny, compared to Windows (PC) applications, so the same rules don't really apply. Yes, they do, okay, but these things simply don't happen.
You really shouldn't notice any difference between 448MB of RAM and 576MB of RAM. If you do, it's in your head, probably because you want to believe it. Perception is not always fact.

I agree with you but if you are a browsering the internet and listening to music and have couple of other clients/apps running you might see a jump in the memory usage.

Yes, of course, but still not to the extent that we're talking about. I've never seen the memory usage on my HD2 over about 60%, and I use it very heavily.
Like I said, the (PC) Windows rules don't really apply to WM.

I guess so, my professional exprience is working with windows server and unix mainframe systems. Which could be different from a phone architecture.

If anyone manages to max out the standard 448MB of RAM then i would like to know how the hell they managed it with winmo!

actual 576mb performance increase?

Probably this is a an old topic. I've read numerous post on weather this 576mb is real or just a trick and the logic behind it. Now it seems this is indeed a real thing but I couldn't find a good post comparing the increased ram vs the old one.
My question is does this actually improve the performance? If so, how come some chef here are still cooking not utilizing the increased ram? Or is it like many have said that releasing the hidden ram actually slow down a little due to the fact this "hidden" ram is exclusive used by certain process to speed up the system overall?
thanks

Well it doesn't increase the preformence since the 448 mb is al more than enough. It actually decrease the preformence a little bit but that is also depending on rom. So its only useful when you 15 apps running that together is using more than 150 mb of ram normally that never happens. So the hole trick is only useful for
-very very exclusive situations
-To show your friends he you see I got now 270 Mb free.

How come it decrease the performance?

I read somewhere on this forum that theextra ram is allocated for some graphics usage, and i think that this is what he means...

has anyone actually done some sort of bench mark comparing the increase ram vs stock one? Graphic test in particular.

No difference to minimal difference in graphic performances from user experience. It's not noticeable.

no the graphics 128 is already taken before the OS alocates the rest. You cant touch the graphics 128 even with the 576 hack.
When 576 is enabled, you still only have 448 to play with, just like when it is not enabled, and you have 448, you only really have 336 that you can use.

Based on what you said, so the 576mb hack is really just displaying the numbers out? With this hack, even it shows 448mb available, you will get maxed out after 336mb. Is this what you are saying?
There is a thread some one made a 448mb page pool and HD2 can still boot up. Doesn't that mean the 448mb can be used freely if needed?

no, what i am saying is if you get a stock hd2, and look at the hardware info, it will show 448MB Ram total, and when you look at total program memory, it will say 336 (or there abouts)
Thats because there is 448 MB Ram, and 128 is taken by the graphics, leaving 336 for the system to use.
In contrast, if you activate the 576 hack, in hardware info it will show 576MB, and in total program memory it will show 448MB for the system to use.
Again, this is because the graphics takes 128MB

I just want to ask u all who think 576 is a trick a question, why do all the chefs here enable 576 in their roms? Are they not smart and intelligent enough, than most of us, to know that 576 is not a trick?

You have to use one of the T-Mobile US Base Roms and use certain radios to enable the hidden ram. Some chefs may use different base roms. It's not really a matter of deciding to enable it or not.... it just depends what base rom they want to use for their rom.

About that decrease wgere I am talking about it is something that windows have to adress more memory. Thats why it is slower. Well actually it isn't a very huge decrease.

Smaberg did create some rom with new base but have 448ram.
Let me quote some for u to read:

After doing some research I have found out the following information :-
Windows Mobile 6.x is powered by Windows CE 5.2.
http://www.slideshare.net/abhisheksharma/windows-mobile-6
http://www.addlogic.se/articles/articles/windows-ce-6-memory-architecture.html
The memory architecture is divided in to 32 process slots. Each with a capacity of 32MB. However with a little testing of my own I have found that it is not possible to run more than approximately 11 applications similtaneously which equates to 28 processes running on my setup. The remaining (28 - 11) 17 processes are operating system specific processes such as the GWES.exe DLL's etc.
If you calculate the memory required for the max of 11 applications it is 352MB which explains why I never see the memory go above 300-330.
The advantage of having the extra memory (576MB) is possibly to allow the other 21 processes to run with more head room.

1ghz hack = fake
576mb RAM = REAL as conclusively proved by advanced testing when it was first discovered, the fact that it comes as default whena tmous rom is flashed on a EU hd2, and my own testing (i built a rom wiht a 400mb pagepool and was able to sucessfully fill the remaining 50 odd mb of ram before the system gave out)

you're probably on a ROM whose Chef has chosen to differentiate their ROM from All the other ROM's whose Users actually benefit from the 576MB RAM that's there...
How do ALL the Chefs who Enable 576MB on their ROM's know this is NOT a trick? (Aside from the fact that there is nothing changed in the Registry to "Show" 576MB)
We tried creating a Pagepool of 448MB (on 576MB ROM's that's what's left after the 128MB is allocated for the Graphics etc.)... As you know, increasing the PagePool decreases available RAM...
by increasing this (PagePool) to 448MB, the ROM should not even Boot if the 576MB RAM is a "trick"... but it did boot... slowly and sluggishly... but it booted.

there wont be a performance boost. Putting more petrol in a car doesnt make it go faster, and likewise more ram doesnt make a machine run faster UNLESS you are already maxing out the available ram, which none of us are.
Personally on roms with the hack, i use the extra memory to run a ramdisk with opera and system cache on it, and that gives a few benefits.
1 - when you soft reset it is wiped and rebuilt, so your cache folders dont fill up all your rom.
2 - Opera especially definately seems to run faster with the cache there. (especially compared to using the sd card for opera cache)
3 - you arent using rom or sd card space for teh cache folders.
as to why it was hidden, , , who knows? there have been a few tentative reports (nothing confirmed) of more echo/sound distortion in calls using the hack, so perhaps the radio utilises it? (I dont believe this myself, i see no difference between with/without 576 roms, but it has been put forward as a theory once or twice)

@ above me yeah that is correct
Maybe in the beginnning they got issues with it and they wanted to release it fast so they decided to give it 448 mb. This is very good possible since first roms only contain 320 mb of ram. Later they found out the bugs so the TMOUS version could released with 576 mb.

[Q] 576Mb Ram on Android ROM?

I've tried to start android rom, with 576Mb ram Windows Mobile rom like (last Leo rom), but Android view only 448Mb.
Is it possible ram hack android rom? for use all 576Mb ram??
Sorry for my poor english
Ps: thanks to all, I bought an htc hd2 phone, only for install Android!!!

Android splits the RAM of the device between the kernel/system (?) and the dalvik VM... or something, either way all of should be used. I thought the Leo only had 448mb anyway? It does according to hTC.

448 is for the system 128 for the video card.
448+128=576

Hi AdrianK,
but htc Leo has really 576Mb ram, non virtually (like htc g1 ram hack, that move ram from graphic to system).
Htc Leo has physically 576Mb dedicate.

No in windows mobile you get the same. You will also see about 448.
I think there is a way since older kernels where 256 mb and 32mb video memory.
But it is not useful since the preformence in android will slow down very much slower animations etc. But believe me we got more then enough ram.

The leo has 576 mb of ram dedicated and a X amount of video ram. There are roms around that make it posible to use the full amount of ram (like the US T-mobile versions)
I am not sure how android uses the ram u wil need to speak to a Android dev about that.

if you look in the general section there are a couple of threads on this issue

576RAM on HD2 with android, how?

Hello all.
im using 2.2 Froyo on my HD2, to say its great!
but, i have noticed that through the Android Task Manager app, it only shows 411.72 RAM enabled, instead od 576, or 448 the default.
what is wrong?
im using also HSPL3
is there any problem i should do something with?
thank you!

Help somebody?

Nothing's wrong - that's perfectly normal. It's one of the side-effects of using a ported OS, rather than one made specifically for our device. It may get fixed, but it really isn't an issue so I wouldn't hold my breath,

i saw on the nexus one and desire (512mb RAM) task managers sees 412mb RAM, so it seems that at MAX we are under of 64mb RAM, but for 412mb we are in line with device like Nexus and Desire
(on Galaxy s, 512mb and they see at MAX 338mb...on new Galaxy they see 448mb starting from 650!)

I think it starts at 576 then loads and locks the essentials to run the OS in the memory and calculates the remaining after that, if that makes sense.

Its normal. This same app on HTC Desire shows you the same result - 411MB. The rest of the ram is used by system/gpu/etc.
Android have full ram of HD2, not only 448MB !
