Hi,
How to extend memory product?
This product have 128 mb of RAM and 64 mb of RAM in technical fact sheet but only 37.63 mb for storage and 48.02 for program in use
Where is the memory missing?
Thank
Some observations:
HTC say 192 MB on their page
Settings -> Device Information says 192 MB
So I guess we have established there's physically 192 MB.
Now... This is where it gets confusing:
Settings -> About says 113 MB. Why is the rest hidden, and what (if any) is it dedicated to? That's 80 MB gone. On my P3600 only 15 MB is subtracted here. VGA screen can only account for a few MB.
The task manager also says 113 MB, and with no applications running except TF3D after a soft reset only 55 MB is free. 30MB more than my P3600. Killing TF3D and soft resetting nets another 10 MB.
Naturally there can be differences depending on kernel versions, hacks and so on.
Some interesting math:
192MB (total) - 64MB - 15MB (value from p3600) = 113MB.
To me it looks like 64MB has been swallowed, or dedicated to 3D (why on earth would it need 64MB), or something else. The 15MB portion I assume is for kernel memory. As a side note, current HaRET version reports 128MB.
Thoughts?
My thought would be "What does this have to do with ROM Development?"
Wrong forum. Let's try and keep the place tidy.

IMO this has a lot do do with ROM development, seeing as custom ROMs strive for more free memory. I did debate putting it in the "Diamond" forum, but most posts are less technical there. If a mod disagrees feel free to move it.
Also, the only way you could possibly do anything with the ram setup would be a ROM modification.
I don't own the diamond, but couldn't this 64 mb be some video memory, like some pc embeded controlers?

It could, but 64MB is a crap load for a barely capable chipset and a 640 * 480 screen. I have not seen any details on what kind of 3D hardware is actually in there, as they're holding the inner workings pretty closely wrapped.
My guess, and correct me if i'm wrong is the 80mb preserved for the cab files?
Settings-> Device Information says 192MB Ram, 256MB Flash.
I can give you the right answer:
The 64MB are reserved for the opera browser! I've read that somewhere else,
unfortunately I can't remeber where.
So I guess there would be cooked roms in the future without opera
and 64MB more ram...

what do you mean? like an old extended rom?

yes..................
i dont think that it would make sense to waste so much RAM for the cab files,
because they would only be needed once in the customizing process at the
first start of the device...
as i wrote above, according to my findings the 64mb are reserved for opera!

The cabs file or the extended rom takes up storage memory and not the program memory. I read it in some review that 64MB of the program memory is dedicated to the GPU for graphics rendering of the VGA display.
Quallcomm CPU with 3D graphics requires 64MB RAM dedicated to 3D functions. No other data can be placed in thise 64MB and it can not be freed.
that's why Diamond (and Sony Xperia X1) have so huge amount of RAM.
64mb just for the 3D? That explains why there weren't any 3D drivers in the kaiser and the polaris then.....
ok this is ALL BS, the 64MB isnt "reserved", Windows Mobile reports the RAM and ROM differently then a usual PC / Windows operating environment.
It falls back on the NAND partitions and whats allocated to what. So in future this still has nothing todo with "ROM Development" so please post this in the General diamond forum.
PS: ET did partition the NAND and he ate 45MB of the ram
jesus you rarely see this load of BS
opera, noo, say that was meant to be a bad joke.
and please do not confuse ROM and RAM. cab files for RAM, when the ram contents get lost on battery removal?!? also the nand partitioning doesn't matter for ram, nand is rom.
not sure about the 3D, but it is quite unlikely it'd want 64MB ram. (I can check later if it accesses that much.)
what is for a fact is that there is an extra RAM shared by the radio and the SPL. the OS does not access any of it normally - but *you* can programmatically access it if you really want to, or even by using pmemdump . (except you are less free to access some parts that the radio restricts access to)
however this RAM is present in all the MSM7xxx, but not reported in deviceinfo on kaiser etc, and seems to be 32MB only (though on diamond I saw indication that it might be 64, I will have to re-check that, probably my memory is failing).
but, what appears in deviceinfo is just a hardcoded value that HTC decides on. maybe for marketing reasons they chose to add this in the total RAM.
one last fact - the OS on the diamond only has access to 128MB of whatever this 192 is, this is easily seen (in nk.exe, romheader, etc), the rest is definitely reserved (either radio, or 3G, etc..). so it isn't WM itself that is eating it up.
that's the best I can say so far without specifically looking, but this is an interesting question and I'll look into this.

Finally, someone who seems to know what he's talking about!!!
It's amazing how many fake problems arrise in this forum because of the lack of knowloged of people, which leads to "theories of conspiracy" and sometimes to funny jokes...
64MB RAM for Opera is a good example of a joke...for the love of God, my Opera on my PC, while working with torrents, emails, thousands of favorites, browsing history older than my great-great-grand-father, only takes 40MB RAM...so why the hell would a **** program like opera mobile would need 64MB RAM?...
Anyway, if you're not sure about what you guys are writting, it's better to stay shut up, instead of inventing things and inducing other people in error...
HastaSSSS

As fun as conspiracy theories are, I'm happy to get an answer that makes a little sense
Hi everyone,
After a Soft-Reset with TF3D disabled this is what I get:
Program Memory
Total: 107.71 MB
In use: 56.13 MB
Free: 51.58 MB
I am using the EnergyROM for my Touch Diamondm build date July, 22nd.
The HTC Task-Manager shows the following Processes:
HTC Task-Manager said:
gwes.exe --- 11565kb Memory Usage
device.exe --- 3137kb Memory Usage
shell32.exe --- 1749kb Memory Usage
filesys.exe --- 1598kb Memory Usage
services.exe --- 1445kb Memory Usage
cprog.exe --- 822kb Memory Usage
dotTaskMgr.exe --- 96kb Memory Usage
connmgr.exe --- 88kb Memory Usage
NK.exe --- 1kb Memory Usage

All of these running Processes are using added together 20,541 MB of RAM.
But remember what Windows Mobile said:
Memory in Use: 56,13 MB.
Less the 20,541 MB, which the running Processes are using, there are 35,589 MB, which are reservated or used, but not by running Processes. So my question is:
Who uses the 35,589 MB of RAM, without being shown in the Task-Manager?
Maybe some of you guys knows the Answer
Greets,
Felix
Its the ROM itself which is loaded in the RAM (i guess)..
i also want to konw
Services and things are also loaded into the RAM. There are more than just those processes running. And along with those processes are the images and extra files they use etc which are also loaded in the RAM.
For example the phone canvas - It runs off cprog.exe which says it only takes up 822kb of RAM when in reality it uses up about 8-10MB because of all the images it has to load.
Not to mention the page pool - If the chef runs a higher pagepool then you're RAM usage is going to be higher on boot.
OK, thanks. Is it possible to view the running services and deactivate some of them?

Yes use dotfred's taskmanager. You can then view the services.
If you really want to save a sizeable chunk of RAM. Disable the HTC dialer and enable the Windows default one. You'll get about 10% back.
allready did that
felix you mean Kb not Mb. 20,000Mb = 20Gb and the phone cannot have that much!
, stands for 20MB and 541 KB
We dont use . or , to show "1000s" here.
we use it to show post decimal positions

How do you do that?
I also had a go with this version of EnergyROM but gave it up for now due to a lack of memory. When closing apps etc. the memory was never freed back up. I also found TomTom had problems after running for a little while. If there is an answer to this, I would switch back as it's the nicest ROM i've tried to date.
How can i see the detail of rom/ram & cpu in my htc hero
I wan to know whether my htc hero is prefect or not!
So i want to see the detail of rom/ram & cpu in my htc hero, but i did not see it. So how can i do?
the same about up
I just want to see the hardware detail in htc hero.
I just recently got my TP2 in the mail yesterday am I'm new to everything especially window mobile phones. It says that the TP2 has 512 MB ROM and 288 MB RAM but when I check my memory settings it says:
Storage:
Total 285.44MB
In use:52.77MB
Free:232.67MB
Program
Total:188.21MB
In use 89.37MB
Free:98.84
Someone told me that this is right and that the rest of the memory was hidden memory can someone confirm that for me? Thanks!
Welcome to forums
That is correct
The important is the free RAM you have and that will depend in what ROM are you using, as some of them take a lot of RAM and some others leaveyou with more space.
To give you an idea, I´m running Energy ROM and I have free RAM of 60-80Mb
and before I had a clean ROM with no manila and I got 90-110Mb free.
Hope it helped,
And don't forget to vote!
Yeah, quite a lot of that memory is part of the baseband (so it can't be used as regular RAM), a lot more is part of the pagepool (a program memory cache), some by the radio stack, some by the frame buffer and some by the XIP (kernel), so that 288MB of RAM turns out to be much less for practical uses. If you're interested in learning more about how RAM is used in Windows Mobile, this MSDN article helps explain things a bit.
In light of recent discoveries about the HD2's hidden 128MB RAM, I've written a small application which uses the native Win32 API to allocate as much memory as it can (up to 2GB), and verifies it.
Notes:
This application is designed to test the limits of your device's memory. In particular, to test if the HD2's additional 128MB is actually usable or not.
This application will attempt to allocate as much memory as it can, OS limits notwithstanding. The application allocates memory in the OS's shared memory space, which means that it isn't privy to the usual 32MB address space limit.
Because the application isn't limited to 32MB memory usage, you don't need to run multiple instances to consume your memory. Just one instance will do.
This application does not use .NET, and instead uses the direct low-level kernel memory management functions (VirtualAlloc and VirtualFree) to reserve, commit, and free virtual pages. This means that the application has much more precise control over memory, and can consume memory until only a couple of megabytes remain.
This application verifies the memory it allocates, by writing a byte pattern to the memory, and reading it out again. This is necessary because the Windows CE kernel does not commit pages to physical memory unless the memory page is read/written from at least once. This also guarantees that the memory is, in fact, usable and valid.
The attached zip file includes an executable file and source code (C++, requires Windows Mobile 6 SDK).
hi! i've tryed it in my rom without the hidden ram enabled and the result is:
Success:could not commit pages
memory eaten:132MB
and after the programs close my free ram is 145, i guess last 10mb are not usable for some reaso? (WM6.6 memory management?)
regards

also when used with rom with hidden rams avaliable it closes before it the 1mb is filled
hm, got 180 on my rom
Memory eaten : 276 MB
after 290 MB free
Sorry. This is not working for me... It did not constantly allocate any ram on my device...
with a modified version of my "old" program, i was able to eat up 99% of ram... Still, I think in my first attempt i did proof the existance, cuz i definetly used more then 448 MB of RAM....
greez
Soft-resetted my HD2, run the app. and got 204 MB. So does this proove that I don't have any hidden RAM or not?
everyone has 572mb- stop bothering...
We don´t have the 1. of april, but carneval is still going on, so this may be the reason for this joke i think.
I'm interested if this will work for X1?
it is for HD2
but onyone tst this for X1?
sorry for my bad english
Is 25 minutes to long
I have the htc touch pro with mightyrom and i am running this now. it has been about 25 mins. is that to long or can i assume it does not work on my pro.
Do you think this would work on Rhodium too?
Thanks,
Im getting 272-276mb eaten fairly consistently after the os has been up for a few hours.
and 280-284mb after a soft reset on my HD2

It's odd, it should work on any WM6 (or higher) device.

i try out but i don't see any change in ram memory... stil 179mB..
Keep in mind that the application frees up all the memory it chews once it's done. So after the application exits, your amount of free RAM will not be changed. The application should report how much memory it managed to allocate once it's done, and if you open up the memory screen in settings (or whatever) you should see the amount of free memory drop as the program runs.
Sounds like some pretty heavy stuff. this is gonna be huge
I think, this program can be used for cleaning ram
thank.
