[Q]RAM 288 or 195.59 MB; ROM 512 Or 322. 67 MB?

Hi,
In the specification sheet of HTC HD, it is clearly said that Ram is 288 and Rom is 512. But when I turn on the device, I saw that the memory for storage is 322 (71 in use) and for program is 195.58 (80 in use).
Where are the missing part?
288-195=93 MB of RAM
512-322=190 MB of ROM?

Yes, because if your ROM was empty, your device would not start up. If your RAM was empty, you wouldn't have an Operating System loaded into it to run it.
The figures you have quoted are the factory / in use figures... i.e. Once you have started your phone up, some of the RAM gets used up by loading the OS from ROM.
I hate to sound patronising and pedantic, but if you had to ask that question, you should have probably bought an iPhone.

I knew this. But I am surprised that the OS takes such a large mount of RAM and ROM.
Do you mean that 512-322=190 MB of ROM is used for storing OS and other default apps like manila; and 288-195=93 MB of RAM is for WM 6.1?
After a soft restart, there are already 80MB RAM in use so I only have 100 MB for other apps out of 288 MB!!
I guess there should be a way to reduce the RAM and ROM usage by deleting some default apps. There is wm PPC comes with 128 RAM which gives user <100 mb to use. I am expecting that since HD has 288, I should have at least 200 mb instead of 100 mb to run my apps.
PS: I dislike the way apple manages iphone and mac. So no thanks.

Lots of the cooked ROMs in the ROM development forum cut out a lot of the fat - there are varying degrees between completely minimal to fully functional - depends on what you want. I think you will find it very difficult to fill the ROM on your device with programs etc - and media is what the Micro SD slot is for.
Could maybe do with a little more RAM at times but you can kill stuff with the taskmanager if you find your phone getting a bit sluggish.

I agree with you on this point.
Are there any tweaks to do this?

You could always use CleanRAM which does as it says, cleans RAM. Some apps or games like Xtrakt or NFS Undercover sometimes won't run due to insufficient RAM. After using this app on setting 2 they work.
Other than this your best bet is to use a lite rom with little or no apps installed on it so you can choose what you want.

Thanks.
The lite rom, 6.1 or 6.5, does a lot to reduce Rom, which is not so useful, but not that much to the Ram.
The available ram is still 190 ~ 195 mb.

However, it does cut off the Ram in use from 80 to 45 mb so finally one has 150 mb. but where is the missing 288-195?

I think you might need to just get over it matey. In proportion, it's actually not a lot of RAM usage at all. Not when you consider Windows Vista is happy when it has 1GB all to itself and then another GB for programs to run in. That's about 50% for the OS. You're moaning about the OS using about 35% of your RAM.

for PC or laptops it's fine with that usage because you can buy rams at very cheap price.
I just dont understand why there is a missing 100 MB ram for wm 6.1 os. the other phones, such as htc nike with 128mb ram give program mem of 100mb. so the os takes only 28 mb.

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!

Available Memory

So when im not running anything, when i open Advanced Task Killer it has like 125M is this right???
So what the other 387MB doing?

what I see
when I 1st start I have about 230MB, after a few minutes it goes down to about 90mb...without opening anything...seems many programs on the Samsung "open" by themselves...also, I see that the CPU goes down to about 100Mhz so I keep it at 1000Mhz with setcpu....plus deleted many Samsung apps(about 30MB)...helps with the lag...

Don't worry so much about it. This isn't windows, you don't need to worry about free RAM. Android will kill tasks as needed to free ram when it needs to. Some of that is likely used for disk cache as well. That will also be released as needed. Let the OS do its job, it's quite good at it..
Killing some of the bloatware will help as well, but you need root.
I also think that this phone, like the G1, has some of the speced 512M ram dedicated to the camera, GPU, and other stuff. In the terminal, free shows about 388M as total ram.

is it a good to create a swap partition on the SD card?

Why on earth would you want swap with this much ram? You likely can, with root and swapper, but why? This phone doesn't need it like the G1 did. Swap could help keep more apps open in the background, but there are already a lot of them there. I don't see any benefit to swap right now. What isn't working for you that you think is related to low ram?

As with the nexus one, not all 512mb can be addressed by the system right off the bat; we may need to wait until a newer kernel comes out

[Q] RAM manager

Hi,
I looked at my free ram and on daily use I have 1 GB of free ram.
So is there any sens to use ram manger to allow android use more ram (mean to not kill app and has less free ram)?

Unused RAM is wasted RAM (just before anyone else says it )
I have 1.3GB of RAM free on my N4. I wouldn't recommend a 3rd-party RAM manager, and just trust Android to handle it
Unrelated, but I have some weird memory leak issue on my N10 that basically causes all RAM to be taken up by something eventually, and all apps end up Restarting. Quite annoying, but the only thing I can do in this situation is reboot the tablet. Can't say I've seen or heard of this on the N4.

i cant say i like the way android does it, even though it does do it. i use greenify, and autostarts to prevent apps from starting in the background. also, i change the numbers to androids ram management. now im happy

But greenify make some apps start slower, yes? (because they have to start again)

If you have widgets on your lock screen or on your home screen they will use up ram. Uninstall any apps you rarely use to free up ram.

Don't see why you're worried. You have as much FREE ram as an s3 does on the box
On a more serious note, I doubt you'll see any difference by freeing up ram. 500-600 mb of free ram = smooth experience generally

I'm no expert, but what I've read on these forums, it's best to just let Android take care of it. Android has come pretty far with memory management, and third-party apps might just end up taking more RAM/battery.

You're wasting your time worrying about it.
