ROM & RAM Usage & Reporting

I am having a tough time getting my head around how WM5 reports ROM & RAM uasge. I believe the system has 128MB ROM and 64MB RAM, so...
-----------------------------------------
I would expect the memory usage to be reported like so:
Storage
Total: 128 MB
In Use: 38.54 MB
Free: 89.46 MB
Program
Total: 64 MB
In Use: 31.73 MB
Free: 32.27 MB
-----------------------------------------
But instead I get:
Storage
Total: 47.46 MB
In Use: 38.54 MB
Free: 8.92 MB
Program
Total: 44.01 MB
In Use: 31.73 MB
Free: 12.28 MB
-----------------------------------------
So what happened to 80 MB of ROM (Storage) & 20 MB of RAM (Program)? The image file (nk.nbf) in the OS installer is 80MB in size so it seems that maybe the system subtracts that amount of space and just shows it as not even being there. Am I correct in that deduction? Does that mean that the 38MB of Storage in use is all due to applications that I have installed?
If the above is true, then is the system doing the same thing with the program memory (RAM)? It caculates how much RAM the base system uses, subtracts it from the 64MB total and reports that it isn't even available? If this is the case, why doesn't the system just report 64MB total and show what the system is using? Also, when I use MemMaid to check running processes, it only reports around 11.2MB in use by the running processes. What is using the additional 20MB (in addition to the 20MB that is not even being reported)?
So...
Is there a better way (instead of MemMaid) to see what is eating up the RAM?
I have removed as much as I can find (plug-ins and such) and have it up to around 20MB free with just the essentials running. Of course there may be standard OS stuff & T-Mobile stuff running that isn't really needed, but I cant seem to see any of it. What can I do to free up as much RAM as possible?
I am running the official T-Mobile 2.26 ROM. I assume the cooked ROM images eliminate the "junk" and free up storage space, but do they also free up program memory? If so what can I expect to gain in available RAM over the T-Mobile ROM?
Thanks in Advance,
Dave

Yea I posted part of it a few days ago in a thread someone else started, but wasn't getting any responses. I figured I would add more detail and see if anyone has any valuable information to help me out.

Thanks, but that wasn't any help. It would shows what is being used in "Storage", but didn't show anything in the way of "Program" (RAM) usage. Even though it let you choose between RAM & ROM, it only is only looking at Storage. For instance when I selected to show only RAM it still showed the contents of my SD card.

If you look real close windows consumes almost 78MB itself that's where a good junk has gone!

[LEO] HTC HD2 576MB Ram not what is seems

Hi,
I've been using a cooked ROM with the 576MB RAM enabled. Clearly the total available memory increases 457.4MB.
The concerning thing is when I begin to test the memory. Presumably this extra memory means more applications can run simultaneously. However when i open multiple applications the OS will automatically close applications to conserve memory even when it has not reached the 457.4MB limit.
In previous ROMS I recall the memory would go upto about 290MB - 300MB before applications would automatically close to conserve memory. However with the extra RAM there is no change in this behaviour.
Another issue I have noticed, is when the memory reaches over 330MB, this then stops applications like YouTube and HTC Album from running (this NEVER happens on the roms without 576MB enabled). Clearly there is atleast 100MB more memory available which the HTC HD2 is not making full use of.
Can I please have your views and whether or not the 576MB is actually beneficial and not just a way of stopping other apps running when memory usage is high. Although I believe the extra memory is available, i'm not convinced certain applications can handle it correctly.

I'm using the Energy ROM with Radio 2.08, which gives you 576MB memory. I have no issues with programs losing, I have 7-8 programs open at once. Also I have noticed a noticeable speed increase with the extra RAM unlocked, and of course with the new ROM.

people want to believe in the 576 mb ram trick
truth hurts

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.

Abolisher, to test if the 576Mb Ram trick works, you can make the following test.
Create a 128Mo Ram disk, fill up this new storage with data (internet cache for example) and run agin your tests, you'll see that you could fill all your ram and your data on the storage will be OK.
Some tests were done to prove that the 576Mb trick was real.

Actually it is even more complicated with even more limitations. This article series gives you more insight into memory subsystem in WM/WM:

Well, it's real. But absolutely useless unless any real life working scenario is found.

576MB does increase performance.

The mass hysteria on this subject and tons of noobs lurking for "576 RAM" effectively make this story a worthless hoax.
I know. I've misread his question regarding LEO1024, just missed the "MB" point.

i am going to clear this up once and for all
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)
end of story
G

I've tried to load a lot of programs to test 576mb ram. After 10min test i loaded ~20progs and: In Use 372mb ram free 86........so i think 576mb is REAL I also tried memory test program that used all ram except last 10mb....

Real life tests with documented results. Please.

Something to keep in mind if you are opening loads of apps to test the memory:
When i have Opera 10 running in the background, it sometimes stops me opening HTC albums saying there isnt enought memory when there clearly is. As soon as you close it, it opens again.
So maybe you have opera 10 running when you try to open HTC album, causing the error. Close opera 10 and see what happens

That Ram bonus would be usefull if we were using ALOT of apps simultaneosly . But never in my experience with this phone needed more ram . So If you plan on installing a long list of apps and running them all in background(just to boast) maybe more ram is required. But aside the app that eats ram to check if it is valid i do not know of anyone to have reported to reach the limit with even pro usage.
If the phone hardware recognizes the extra ram and uses it then it is there. The extra tmous radios enable the phone to use more of its hardware perhaps? Remember PCs...? Windows x86 works up to only 3 gigs of ram even if you have 16 gb of ram installed onto the motherboard. Using a higher functionality operating version in x64 mode (for dual-core proc) enables the " hidden ram " . The ram was always there but the system needed a better programing to use it . I am not much of a computer expert but i guess its not fake, only that u do not need it !

It is my personal thinks:
The fact:
- ROM that show 448 MB run smoother than ROM that show 576Mb as I fell and some tests.
The reasons may be:
- HD2 (Leo) have enough 576Mb, it is real.
- With basic ROM, the manufacturer hide some part of RAM to use it for permanent applications/programs that may support for WinMo run faster and smoother and that apps/progs do not need to start/stop usually. The hidden part could be set to priority access mode (may be). And the RAM shown for you is 448 Mb only and you could do every thing with this part of RAM.
- The ROM that hacked RAM side to be shown as 576Mb open the hidden part and make all off RAM could be used randomly by user. In that case, top necessary applications run by Windows should start and stop many times, it may make the OS be slower a little.
It is my idea.

The question is not If 576MB RAM is real (its proven to me), it's the question if there may be 1GB ROM also.. as I don't see any reason why they would do that little change if they alrdy didn't change the 576 RAM thing
The only question is.. why don't TMOUS roms unlock the (may) hidden ROM?
I guess it could some realy deep coded software thing.. not sure if thats even possible..maybe others can tell
We will see alot more clear if we can boot into linux =)
Cheers

the actual chips are different for the rom. cotulla posted the two chip model numbers. one has 576ram512rom onboard the other has 576ram1024rom.

[Q] "cheated" RAM?

Hi,
I got new phone dual sim from China on wm 6.5, and in the settings/system/device information it shows 128mb of RAM, while in settings/system/memory it shows only 77. I checked 2 independent applications (cleanRam and advanced task mgr) and both of them show 77mb.
Did chinese manufacturer cheat me?
Thanks

No, you just don't understand how RAM works.

Can you please be more specific?
In my pc, running on xp I have very clear and reliable information about total ram in task manager (total, used, free), so I compare this to windows mobile. And it's different.

it means your phone is using 51mb of the memory and has 77mb free memory left to use. when you scan your phone with clean ram it shows you the free ram available. same do the task manager.

I've seen this similar problem on my iPhone4 (china/clone).. it showed, 16Gb of internal/phone memory but when I tried to put a song (more or less 5mb) it showed that I was already using 60% of the total space.. and the annoying part was that it still showed the same information before I transfered the song..
I really have to agree that we are being cheated by these manufacturers..

Hi,
come on, I am not so "newbie"...
it shows 33 used+44 free=77 total, while in specification says: 128mb of RAM

I don't know how WinMo works (never used it), but on Android there's RAM designated to the Dalvik VM and another lot designated to the system/kernel.
I guess it's similar on WinMo, 51mb is probably being reserved for something useful.

Since it's a Chinese clone it's probably using really dodgy flash memory, which is acting up, rather than an intentional modification to show a larger capacity.

I just read that WM 6.5 on start takes around 40 mb of RAM, so something independent from WM is eating my RAM, or simply does not exist physically... any idea how to check it?

They are being reserved as "pagepool" Windows Mobile caches frequently accessed files in there for quick access.
You can decided how much you want to reserve for pagepool when you flash a new rom with tool called PagePool_Changer

There is 128 MB of ram, but you don't get to use all of it for program memory. Some is reserverd for the page pool, the radio, hardware buffers and for the kernel/OS. The task managers just don't report the ram that you have no control over. This is how it is with all devices.
Edit: try reading this.

I am not sure how their phones work, but I do know that awhile back, I purchased a 16gb flash drive when they first came out and when I plugged it into my computer it read 4gb and even after formatting it still is only 4gb. It says 16gb on the drive itself but there is NO way that is correct. Be careful when you buy some of this Chinese garbage.

First off, quick question. Anyone know why My phone RAM is Completely spent? It constantly sits around 15MB free of 110MB. Larger games wont load and just crash at the loading screen to the home screen, other games are lagy at times. If this was a computer I would say its a ram issue and I am running out of usable ram. Any ideas?? I just want to get this phone working so I can sell the headache. So far this ROM seems to run awesome and has none of the issues I experienced with the other ROMS except when put under load.

64MB swap and still no change

still curious as to why my RAM is spent..... Installed a RAM app and confirmed 15-20MB available of 115MB. I used this app to kill the running precesses and it brought me up to 45MB free but it gradualy dropped back down to 15-20 free. Even with all services Killed, including the system sevices, I was still at 45MB free of 115MB. What is using the other 70MB? Anyone?

I'm guessing it is just an inaccurate reading and the operating system does not run ~500mb by itself since iPad2's only has 500mb ram and it is still functional.
