Increase free Ram Allowed for program

Good Day ,
in my S200 , after installing many Programme , i have :
18.37 Mo free allowed for program & 35.54 Mo Free for storage
ca we increase the the total Free allowed for program and decrease for the storage ?
Many Thanks

S200 have 47.5 Mb flash ROM for Storage and 44 Mb RAM for Program running. When we install the program, it implicitly going in flash ROM (if ‘device’ was chosen) or explicitly in Storage Card (if we choose so). Unfortunately, boundary between FlashROM and RAM can not be movable because they have different nature. In the previous version OS (like in PocketPC 2003) this boundary between Storage and Program was movable because they all reside in the RAM.

there is any chance to have more than 18.37 Mo free allowed for program
Many Thanks

Without making changes in hardware - NO.

Thanks :wink:

Keep in mind, you have 18.37 Mb after some program installations and those programs runs already (like SpbPcketPlus and so one). So 18 megs RAM left are good deal chunk, it will be enouge to run few more huge programs, if you need them all same time. Ask yourself, how meny and how big programs do you realy need same time to run?

Program Mem (RAM) getting less&less

Dear All,
I run the O2 XDA as is w/ 4 heavy add applications, Navi, PIM, Wallet and Blackberry.
I start w/ 50% RAM usage after soft-reset. After some days I see 75%
There is either a memory leak in the applications, or DLLs are sitting there and are not unloaded from mem.
IS THERE ANYWHERE A TOOL TO MANAGE AND REVIEW THE DYNAMIC MEMORY ALLOCATION (RAM) ??
Thank you for info.

I am not aware of one. The Sktools application has some useful clean-out stuff and has an option to manage running processes. It does not sadly show their %Ram usage figures.

Ram usage
Hi, thank you for your reply.
May be somebody else from the R&D side has something to say.
I recognised that the sum of RAM usage, as indikated by tools like SK or Taskmanager does not at all come close to the RAM usage indicated by System resources.
Hans Kurscheidt

Sorry to post to myself,
but I found out that after soft reset, Task manager tool and mem maid show significantly different memory allocation for the processes running after reset. For example filesys 2,85 Mb versus 2,4 Mb.
What to believe ??
All in all, I come close to 8 Mb mem usage for the processes. with 49 Mb free, I count 56 Mb. If the total RAM is 64Mb, where are the other 8 Mb? Can this be other code, copied into RAM for execution ?
Does somebody know, if the display has its own memory ?

you are really someone )
Trinity have only 64MB build in , how come it have 64MB program memory ? DId you have brain ?

--yes,
if the device has 64 MB SDRAM, why is it that most cooked roms
generally present approx. 50 MB of that?
is this a limitation or is missing 14 MB used for a special purpose?
Thanks for any advice.

?? because it takes up space to install the operating system.. even a 'bare bones' operating system is still an operating system..
did you ever wonder why there's space missing from your hard drive after you install windows xp?

http://www.htc.com/www/product.aspx?id=470
Memory ROM: 128 MB
RAM: 64 MB SDRAM
What is the ROM 128 MB designated for?
Thanks for your patience with me.
--kara

if i understand him correctly, he is referring to the program memory i.e. RAM not ROM. the 128MB ROM is meant for installation of OS (WM) where the 64MB RAM is the execution power. we normally get ~20MB-25MB RAM free out of 64MB total. i believed the rest (64MB - 25MB) was used for other services once WM started.

yes, that is what i'm trying to understand..
in this p3600 specification from HTC:
http://www.htc.com/www/product.aspx?id=470
it lists>
128 MB ROM
64 MB RAM
=================================================
for the 128 MB ROM
I assume the 128 MB ROM contains the OS installation, with
some component of this ROM hidden/reserved.
E.g. some cooked roms released have 'Big Storage'
~70 MB available to the user for NV storage
the remaining 58 MB comprises OS installation and a reserved
area.
=================================================
for the 64 MB RAM
This is the volatile memory available for the OS to boot & run, and
for program execution.
However, on most cooked roms I have used, under
Settings -> System -> Memory
'Program Total' is reported as ~50 MB.
So my question is - where is the remaining 14 MB RAM??

as dum as it sounds i've wondered about that too
even formatting issues aside (like how hard drive capacity is always lower than reported), 14MB seems like a lot to 'go missing'.
why doesnt WM even report it? because its being used by the system for services? so then why does it ALSO report itself using around 20MB of what's left?
that way, it's like 14 MB used (hidden) + approx. 20MB reported (shown) = approx. 34MB total? :/ hmm

OK - You have a PC with 1GB of RAM say. Once say windows xp has booted up - your AV started etc. you probably have 684MB say of RAM left, so Where did the other 340MB of RAM go to?
Think about it.

wtf i still don't get it... dont be mad
i mean mine reports 2096236 KB... a full 2048MB of RAM
BUT of course 100-300 minimum will always be in use for the system itself
whereas in WM, it reports like 48MB total, AND say approx. 20MB in use
ok so the 20MB minimum in use will ALWAYS be in use because of windows mobile itself. FINE.
but why does it only represent 48MB as available?
and if that is the case, there's that missing unreported 12MB, PLUS that minimum 20MB always in use
that's what im curious about

Just think that Windows XP takes 250/300 mb of ram space....
PS: Please edit your title... Someone could understand that you really have a 64mb free ram rom......

Maybe it is for the Radio Rom etc...or maybe Microsoft are stealing Ram and stockpiling it....lol

This is actually a valid question.
The system has 64MB of ram, some how 14MB of this ram is allocated away before the OS loads. This leaves 50MB of ram left for the OS, which uses about 20 MB and leaves 30 MB of ram for applications.
I think everyone understands this part.
The question is, what part of the phone is pre-allocating 14MB of ram.
My only guess is the videocard, if not that then it might be the pagefile.

Does it really matter where it goes? Obviously if that memory hasn't been exploited yet by the excellent cookers etc in here....then it can't be of any benefit.

I concur with tetsuo55.
The reasoning proposed by Andych and others still does not quite
correlate.
i.e. 64 = 14 (OS) + ~20 (progs) + ~30 free
the ~20 is supposedly attributed to basic progs,
e.g. phone, filesys, mail etc..
A listing of such process summates to approx. 8 MB total.
That still leaves 12 MB of unaccounted for basic function
and userland process consumption.
Regarding the ATI video chip, general investigation and
settings check of tcpmp would suggest at best it is a
4 MB chip (whether dedicated or shared)
I cant see the 'remaining ~14 MB' that I'm searching for
being used for paging. Paging is part of overall virtual memory,
and involves page outs/ins to a location on some type
of physical media. Additionally, with the usual ~ 30 MB
ram free, in the context of these devices, a swap requirement
is unlikely given the 'free' memory available.
Although 14 MB may seem peanuts compared to standard desktop
ram configurations today - with a p3600 + WM, recovering the
14 MB (if possible) would provide a much welcomed bonus to
the trinity.

ahh now we're onto something good work ks1781...
i fully agree with the need to just find out the answer to this... most likely it's something that will be perfectly explainable and make sense and we won't be able to do anything once we find out
but it sure would be nice to know

OK I have the 'answer' - straight from a Windows Mobile blog - I'll post it here cos it's all straight to the point and interesting (somewhat) Link is HERE
The Page Pool
Applications use RAM in two ways. There is code that runs, and there is data that is created while it is running. On a NOR device, the code can run directly from the ROM and not be loaded into RAM first. This process is called XIP (eXecute In Place). NAND devices can't XIP, so their code is loaded into RAM and executed from there. If you don't have a Page Pool, this code is loaded into normal RAM. The Page Pool is a mechanism to limit how much code is loaded into normal RAM. With a Page Pool, we can unload code that hasn't been used in a while and reload it later if we need to. We can't do that without a Page Pool.
On a typical NAND-based WM5 device, the Page Pool is 4.5M.
The Radio Stack
Devices with a Cellular Radio have a complicated bunch of code to make their radios talk to cell towers. On some devices, the radio is a self-contained module with its own RAM and ROM. On others, the radio code is stored in the normal system flash. If so, it either needs to XIP, or it needs to be run in RAM. If it's run in RAM, that RAM is taken away from the system.
A typical radio stack takes 4M.
DMA Buffers
Some hardware can write directly into RAM without using the CPU to do it. This is called "Direct Memory Access" or DMA. DMA is very efficient and lets you get a lot more data transferred in the same amount of time, usually for less power. But it's best to set aside your DMA buffers before the system boots. This guarantees that they're there when you need them. PocketPCs have been doing this for a decade. But, back in the old days, the main use for DMA was audio capture. Audio data is small, so the DMA buffers are also small. Video, on the other hand, is big. More data requires bigger DMA buffers.
An OEM will tune the size of the pre-allocated DMA buffers based on what the device is intended to do. If the main goal is still photos, you can use a much smaller buffer. If the goal is recording video, it needs a much larger buffer. If the goal is video conferencing, it needs a bigger buffer still.
DMA buffers range in size between 300K and 6M. For a video capture device, it's likely to use around 4M.
XIPKernel
There are portions of the deepest parts of the OS that have to XIP. If you're on NOR, that code just XIPs like everything else. Not so on NAND. For a NAND system to boot, it needs to load this code into RAM first and then run it from there. When the system is running, it can't really tell if it's running from RAM or ROM, so it assumes it's running from ROM and doesn't count this space.
The XIPKernel region tends to be between 1.5 and 2M.
The Frame Buffer
There is a chunk of RAM set aside to hold everything that's on the screen. (If you want to know more about it, read this.) On most devices, every dot on the screen needs two bytes. A typical Pocket PC has 240x320 dots. That would be 300K. If you have a 640x480 screen, it's 600K. Sometimes, for performance reasons, devices will have two frame buffers. So this could take up to 1.2M.

Thanks joncgde2 - good find which provides a sufficient explanation as to the 'hidden' 14 MB.
There is still another question.
WM reports ~24 MB in use (per earlier screen captures) - where 'in use'
is attributed to running applications.
Checking a process listing via task manager shows the total
apparent RAM in use by these 'running applications' to be ~8 MB.
Can anyone provide an explanation to account for the
remaining ~16 MB??

2 Hardware related questions

hi guys!
i just received my HD2 and i already have 2 questions:
1. isn't supposed Hd2 to have a microUSB conector? it looks thiner and wider then connector i had for my old HD. i didn't have guts to stick the old cable in to check if it works. can somebody confirm the compatibility?
2. what the h**l is that 200Mb (more or less) storage memory? on my old hd i never had the memory problem? HD2 isn't supposed to have 512Mb RAM? isn't all available for instaling things omto them? i am totaly confused
thanks a bunch for enlightning!

mini usb - micro usb..... two different things.
512 ram is for programs and the system to use to run things, like ram on your pc, 200 rom is where programs get installed to, liked the hard disk on your pc. don't forget you can instal to your sd card too.

thanks for answers
mini vs micro = ok
the other one is not ok. i am not refering to RAM but to ROM memory. my bad!
so, again - ROM memory should be 448Mb (or 576MB on some custom ROMs)
how come is not all available?
i said before, on my old HD i never had a memory problem and it took me by surprise

incorrect, there is 448(576 with the right cooked rom and radio) ram not rom.
there IS 512 rom on the device,yes, and windows plus the other pre installed stuff takes around 250 meg leaving around 200 for user stuff.

No, RAM is 448 or 512. ROM is always 512MB. But, about 200-300 of those are used to store the system components (OS).

you guys are right. i am too new with hd2
however, the question is valid - how come is not enough?
i used cooked 6.5.x roms and same apps in my hd with no memory issue

I must say I don't have a problem. small apps get installed to main memory, anything large like sat nav software I instal to memory card. most apps are very small, not much more than 1 or 2 meg, difficult to fill all 200 meg.

Who said it's not enough?
I have around 70MB free now with quite a few apps, no problem so far. But yes we need to think about putting big programs on the storage card indeed (games can be 10-40MB each, typical "big" apps 1-5MB), so yes with a few you can easily fill the internal memory.
But it's also like always, people always want / "need" more even if it's useless... mostly about RAM in this case and the sooo popular 448->512MB fix. With 448MB, you have about 185MB free RAM upon boot. On my previous WM device, I had 80MB free on boot... and never came even close to filling that even with more running programs you'd want to have. So with 100MB more, I'd want to see someone who actually *needs* the extra 64MB...

Its actually an extra 128 meg, not 64, 448meg standard (with 128 set aside for graphics = 320 useable) and after the tweak its 576 with 128 set aside for graphics = 448 useable.

Indeed... seems I can't use a calculator at 1am anymore

100 mega of memory are used for system process other 100+ mega are hidden in all the rom not based on 2.0x t mobile rom

that's correct, phone has 448, 128 set aside for graphics = 320mb.
how much did you think it had?
if you want the hidden 128 you ned to flash different rom and radio.

ok but what about the space? only 200 mb, where are the whole 512 mb of space? and how can I disable some services, because my free ram is only about 190 mb?
THANKS!

alot of the space you lose is taken up by the programs that come preinstalled (copilot etc...) as for freeing up space etc there is a good thread on here somewhere in the ROMs section that tells you what you can delete to free up space. Also SK Tools is pretty good. As for the missing storage i dont know where this goes either. We should have 512 but it never seems to get more than 250 - 300 at a push. I think some will be set aside for Core stuff and some will be the way the OS reads the space anyway (look at your PC HDD for example)
If you need more Ram then you will need to flash a cooked ROM. There is not that much you can do to the stock one to free up that much more.
