Memory in WM6

When i upgraded my Himalaya to WM5, I think I used used the 64 MB RAM version. I used the himaDOC tool to partition my device and give 64 MB to the RAM and 64 to storage.
Will that partitioning persist after I have upgraded to WM6? Ever since I installed WM6 my device is very very slow and it is because there's less than 3 MB of RAM left available. Here's what my machine says about its memory:
The ABOUT menu shows "Memory: 61.28MB"
The Hardware tab in Device Information shows RAM 128 MB, Flash 32MB, Storage Size 30.53MB
And when I go to Start > System > Settings > Memory, it shows Storage Total: 30.53 and Program Total 61.25MB
I am a little confused about what all these different types of memories mean. If anyone can clarify, i would really appreciate it. Also is there a way to increase the storage memory because with the total 30.53, 27 MB is always in use and with the remaining 4 MB, the device is painfully slow.

If you have used DOC partitioning tool, you have 30.53 MB of storage ROM. The rest of ROM is your system and radio stack.
Your RAM is divided into 3 parts: program memory (actual RAM), RAM disk and page pool. They sum up to 128 MB. So, for example, if you have 32 MB of a RAM disk and a 32 MB page pool, you have 64 MB of a program memory left.

So from the numbers I see on my device, does everything seem good or is there anything I can do to further improve memory performance/allocation so that the things will be faster?

Do you have a RAMdisk enabled?
You know, there's no simple answer to "what configuration is better". If it were, you wouldn't have a choice It depends on how many programs you have installed, what exactly programs you're running, and so on...

What's the page pool for?

Ok, i know maybe is a noob question, but i don't understand whatthe pagepool is very well...
I know it has something to do with the system performance but i don't understand how it does work.
What would happend if i set the pagepool in 5mb (i think the smallest)?
If that's bad for the Pda, is better as much as possible?
I'd like to know because it seems to loose that memory asigned as pagepool.
Rom 30MB + S.O. (The hyma got 64mb)
RAM 128 MB
Ramdisk 40MB
program 61MB
Pagepool 24MB
If aplying 5 MB would leave more memory for running porgrams (up to 80MB) and the performance wouldn't be affected, Would be that the best choice?
Sorry for my english. Regards!

The Hima does have 64 MB ROM, part of it for Radio (AFAIK GSM, GPRS, Bluetooth), part of it for the bootloader, about 32 MB for the operating system, part meant to be used for EXTrom I believe (I'm a relative noob myself).
AFAIK pagepool lives in RAM and works like cache, low pagepool makes your device noticeably slower.
RAMdisk is a place to store any kind of files just like storage card, just not removable. It's a bit more volatile, shorting the battery contacts will remove its contents.
Program memory is where active, running programs and data reside just for the time being. It's blank right after any hard or soft reset.
I don't know what you mean by S.O. but the most important area for most of us is the area our device calls (a bit confusing) storage. It's where most cab's install programs plus their data and settings by default. It is normally limited to 14MB, by pulling unused EXTrom area to it, you can expand it to 30.5MB.
Still not much but the best we can do. If you don't know how to do this, there's a sticky.
Did I cover it all? No mistakes? (it's late and under these conditions I recently did make a mistake on the same subject...)

ram disk are soft-reset resistent

rom&ram size

i look in the specification of kaiser in htc site, and it shows 256 rom and 128 ram.
when i look in my memory section at my device i saw
storag 153m and program 101mb
can anybody tell me what is missing, im using the originall rom.
am l anderstaning it wrong or there's another reason

The devices OS and applications take up the space not listed in this case 103 and 27 MB, respectively. The missing space is being occupied or used by the installed OS and applications. The space you see is what is left and available for you to use. If you were to erase everything and look at the space then you would see truer values (not that you can).

So whats the difference between ROM memory and RAM memory?
When I install a program on my device (not storage card), am I utilizing space from ROM or RAM?
And is storage ROM or RAM and program is ROM or RAM?
Thanks

Assuming the same terms appy with my TyTN II as with full sized PCs, ROM = Read Only Memory and RAM = Random Access Memory. ROM is Non-Volatile (ie data is not lost when the power is switched off) where as RAM is volatile (why you get a message saying data may be lost if you continue to run down your battery when it's very low. ROM is generally (much) slower for read and write speed than RAM (hence why RAM is used).
In the case of the TyTN II ROM is what is known as flash memory (because it can be overwritten using a process called flashing). It can also be written to in more general use such as when installing programs so I prefer the term Flash rather than ROM because it's not strictly read only in this case.
When the programs are installed into main memory (rather than a card) they will be stored on ROM (so it's not lost when the power is removed) but will be in RAM as well when the PPCs CPU is working with the program.
If the OP nndd12 looks in Start =>Settings => System tab => Device Information => Hardware Tab the RAM and ROM details are in there but the ROM is termed Flash.

Diamond: Far from 192 MB DDR RAM?

Hello,
I bought my Diamond yesterday from PDA plaza in Montreal. I am very puzzling with the memory I have on my unit. By clicking on Setting and Memory, this is what I have:
Storage: Total: 83.06 MB In use: 26.41 MB Free: 56.66 MB
Program: Total: 113.08 MB In use: 61.20 MB Free: 51.88MB
Very far from the specifications, which are ROM: 256 MB
RAM: 192 MB DDR RAM.
So is my unit defective? or this is normal.
Thanks in advance, because if I need to replace it, it need to be done as soon as possible...

This would appear to be either a Grey Import or Pre-production specification? You should double check:
Go to - Start> Settings> System Tab> Device Information> Hardware Tab>
There you will find all the information about the physical memory?
If your correct then you may want to return it to the supplier or ask for a price reduction if your happy to keep it?
Hope this helps?

Thank you,
Yes, it is written Ram size 192 MB and Flash 256 MB. But why is that so different when I check on setting and memory?
Philippe

A chunk of memory is taken up by the Rom (System Software) and other system resources as they run. As you see new "cooked" roms become available you will see an improved level of memory usage - its nothing to worry about as long as performance is as expected?
I am incredibly envious that you already have the device though - looks like we here in the UK are going to have to wait a while longer unless we want an imported model?
Again - Hope this helps!

Because of all application running on your PDA...I heard that, with the 3D touchflo, there is "only" 90 Mo of Ram available !!

I'm using the Diamond to post right now. Touchflo 3d is a memory hog. only about 30% is free with no other applications running. the browser uses another 10%.

Thanks for all your comments. So to compare with my unit, please could you tell me how much memory you have for Storate and Program. So I will know how my unit compare to others...
Cheers,
Philippe

**** ME! How can it only have 50 MB of RAM free? Ive always got at least 60 free and I have 60 less to start with. Maybe TF3D is a massive hog?
But looking at the things you said, something like 113 available, 50 in use and 60 free, thats a good thing, you must have 192 built in, usually with 128 build in, you'll get figures of 80 available, not 113.
The one thing I dont understand is why the program memory never says that available is the amount of RAM you actually have. Because on startup I've usually got about 20 in use, and thats by the OS. So, when you take available program from the RAM you're meant to have, and get a number, lets say 80MB in this case, whats that used for?

With 128Mb RAM in machine Touch Dual shows 101Mb total, but Asus P750 120Mb. so adding another 64Mb we only gaining 12Mb total? Is that what you are trying to say???

83+113=196 is more than 192MB. Isn't the 256MB only for ROM (so WM6.1 OS+pre-installed programs?)

83 + 113 should not equal anything
Storage is the free space after a rom has been installed and is basically the free part of the ROM. With a lite made rom, it should be as large as possible, and the used storage on first boot should be near zero.
The 113 part is the RAM.
What I'm trying to say is where is the other 79MB of program memory (RAM)?
Because its not like on soft reset, you have say 113MB program free, no you have that available and about 60MB free. the approx 50 that is used up in this case is by startup items, and the stuff windows needs to rum. So where is this 79MB?

I'm sure it has some use. Hard drives are never quite as big as they say because of things like pagefiles, file allocation tables, etc.
Maybe that hidden 80MB is being used by system processes that are kept hidden. That's the only explanation I can think of, because computers don't seem to have a similar problem.

I'm going to agree with you on that! No way they released all these phones with bad chips in them!

Some Clarifications About Memory

Hello,
I would like someone to clarify to me some things about the device memory. My current mem readings as shown in the Control Panel are:
- Storage: 299.01 MB (210.27MB free)
- Program: 183.73 MB (72.87 free)
According to the official specs, the Topaz has 512 MB ROM and 256 MB RAM. How are these two types of memory related to Storage and Programs? Is there a way to mess between RAM, ROM, Storage and Programs in order to achieve optimum memory usage? For example, in my device there seems to be a lot of free Storage Mem available, as compared to Program Mem... Should I need to do something about this big discrepancy?
I would be grateful if someone clarified all this to me.

To be very short:
ROM (Read Only Memory) is where bootloader and Windows resides:Beside this there is more room to install applications (Programs) and to store personal files such as pictures,videos,mp3,docs etc.(Storage). ROM is non-volatile memory, this means that data will remain in the device even if power is cut off and will be available the next restart.RAM (Random Access Memory) is volatile memory that your device needs for ordinary functioning (loads into it programs that are running).RAM wil be emptied if powered off. It does not have sense to compare these two values and try to make them similar. An advice would be to install and store all you can in the Memory Card.Note: some apps/cabs need necessarily to be installed in the device (Programs memory) otherwise they don't work.Note 2: Access timings to memory cards are higher than internal ROM, take it in consideration if you have to decide where to store/install.
...Well I wasn't so short..I'll try it again:
If someone asked me:""why do I have so little free Program memory compared to Storage memory?"
I'd answer:"It's beause of many useless Microsoft programs embedded into Windows that cannot be uninstalled, only cooks can do it"

Thanks a lot for the (not so short after all! ) reply! So, if I get it correctly, the so called Storage Memory is the ROM after all: In other words, these 210 MB that are free cannot be utilized by me in any way, unless of course, I switch to a cooked ROM that contains lots of programs that currently occupy my RAM, and which they will not be needed to be installed there any more.... However, I am not in the mood of flashing and setting everything up from scratch, right now....
The storage card is indeed a solution, yet it has the two limitations that you correctly mentioned... So, I will basically have to stick with the RAM that is left...

In the same order as your arguments:
-Those 210 MB CAN be used by you, by installing apps in it, but I adviced you to possibly install them in Memory Card unless inevitable.
-Cooked ROMs generally free up Programs Memory area (or maintain same memory and upgrade embedded apps).
-Storage card is simply VITAL,access timings and transfer speeds are good enough to support everyday use.
-Then you talk about RAM: You "have to stick to RAM that is left" as anybody,but RAM usage is variable, depending on how much intensive is your device work in runtime. To optimize RAM memory use CleanRam, you can do it manually or schedule it (like I do)...and of course don't run too many apps at the time (check Task manager)!!

I was talking about these 210 MB, which are reported as free in my Storage memory, which if I understood well is the ROM... So I can't use them to install apps in it.
On the other hand, the Program memory (which I have 73 MB free) is the RAM, right?
Or I've got it all wrong?

210 MB is part of the ROM and it is free space in which you can store personal files (mp3,pictures,videos,contacts,docs etc.)--->same as Memory Card but smaller and quicker.The free memory in which you can install programs is in your case 72.87MB and is still part of the ROM(I want to better check this last statement,update coming soon).
RAM is another memory module,physically separated from ROM,it's another chip. RAM values vary with the device workload.
Update: I confirm,to simplify we can say that both Storage and Programs memory is part of the ROM, in no ways it can be considered as being RAM.

Thanks a lot for all the clarifications, sualc! Now everything has been sorted out to me.

You're welcome,cheers
