[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.

You posted CleanRAM v1.1, v1.7 is out dude

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.

I am definitely believing the 576mb is real and just want to know the performance difference and reason why HTC wants to hide this part of ram

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.

Only 256M RAM?

I read on another forum that the advertised RAM is 512M RAM but the Kernel on the SGS can only see 256M RAM.
Can current owners confirm this is indeed the case?
This might be slowing the phone if this is indeed the case.

Crap. Since it is running Android 2.1, there shouldnt be any problems whatsoever. Why dont you download Advanced task Killer and check out the amount of free ram yourself?

I don't own the device but am considering it.
I was wondering if one of current owners could check this and let us know.

Until 2.2 (froyo) isn't the most ram Android can read 256mb?

Nope.
The EVO reads 512M and is on 2.1
i believe the Desire too.
The N1 got a modied Kernel on 2.1 that was able to see 512M.

Ahh my bad sorry

I believe i read in another forum that it's using an outdated kernal. Someone can make a custom rom and fix it eventually.

First of all it does have 512 MB of ram. The problem is that the current kernel can only use 0x50000 KB of it. After reading a bit of the dpram module it seems that samsung report to the kernel that 0x50000 KB is the memory size of the device. I think they did it due to the aforementioned bug.

Do we know if 2.2 will fix this ?

2.2 should but i hope some talented dev can unlock the additional memory before that

I'm using Android System app to check and its showing me...
Ram: Max: 325Mo Free: 132Mo 40% (i have seen higher FREE Mo).
and when i run like almost all the apps i can think of, right now i have like 20 apps running I checked on (Advanced Task Killer) to see what is running, than I went back to Android System and now its showing me
Ram: Max: 325Mo Free: 35Mo.
I can notice lag but it still runs faster than my last N95 8gb. (With nothing running).
Hope this helps.

[Q] Honeycomb TO Froyo ?

Hi there,
I just got my Acer A500, and Iam very happy with it except for one thing which is the use of RAM.
Honeycomb uses half the RAM to operate, so i get 400 mb free only.
I have Htc HD2(448mb ram) with Froyo, i get 320 mb free.
​
So if I change my Acer to Froyo will it give me more free ram than now?

Why do you feel you need more free ram? In a Linux environment free ram is wasted ram. Do things not work as expected, are you noticing any performance related issues that make you think you need more ram? Or, is this about getting a bigger number that doesn't really relate to actual enjoyment of the device?

if you are really that obsessed with your free ram...root your tab and rename/remove any app that you do not think you will ever use. that way they do not run in the background. i have done this with quite a bit of apps and i hover around 450-500mb free.
Sent from my DROIDX using XDA App

yes, things not work as expected !
I thought with 1 gb of RAM I will be able to move between apps without the need of klling them, but now when I move from app to another it become slow in many ways for example, using the keyboard will be depressing each time i press, i have to wait, also, some time it frezez for 2 or 3 seconds, last example is the AutoCAD need 300 mb to work, so i cannot check my email while playing the AutoCAD, i have to kill it then check my email.
