ROM and RAM confusion

I know that JAM has 64 MB ROM and 64 MB RAM. You cant install application in the ROM (unless you cook your own ROM and flash it).
It has also 7 MB Storage, so 64 MB RAM minus 7 MB Storage = 57 MB for Main Memory PLUS program (installed application).
There is a setting in the "Memory" where you can allocate how much to Main Memory and how much to program.
I believe that if you have a lot of main memory your PPC will run faster, just like in PC.
So thats why I use this approach :
- Important (daily usage) applications should be installed in the 7 MB Storage.
- Unimportant applications should be installed in the SD Card
- In the Settings -> Memory, I allocate as much as possible to main memory.
What do you think ?

First of all: The 7 MB \Storage is ROM, not RAM. When you use the bigstorage ROM the \Storage area is approx. 27 MB.
Daily usage in RAM or ROM, unimportant apps/large apps on SD.
Fiddling with the memory slider has only a temporary effect.

so then the big storage is using 20mb from a redundant part of the rom then? as in unless you do the big storage upgrade your have 20mb sitting around doin nothin? and that could be used for programs without using a SD card or puttin them into main memory and therefore allowing you to free up ram while runnin at main memory speed + reliabilty?
Speedn
sorry it was confusing me too

The 20 MB ROM you get extra with a bigstorage ROM contains cabs that are automatically installed after a hard reset, so you have to back them up first if you still want to use them with a bigstorage ROM. Instructions can be found on this forum...

The internal ROM (Storage) is slower than RAM. I'd recommend to use the RAM for very often used programs and today plugins. This is onyl an issue when loading the application (because it's then loaded into the RAM).

Alpine

The HTC Alpine is a faster Himalaya with a better camera (but the pictures are the ugliest ever seen) and with Wi-Fi support. The device contains a 64Mb ROM, and a 64MB DiskOnChip, and 128Mb RAM. The rom contains the OS, Extended ROM, BootSplash and some Serial Numbers. The DiskOnChip contains the Storage directory.

192 MB Memory on Wizard?

Dear All
Please excuse me if my questions look silly:
I bouth a Wizard and read it has 64MB RAM and 128MB ROM total 192MB
The manual also confirmed this.
At startup, evening after hard reset and pressing soft reset within 3 secs, I have:
Storage 47MB Program: 44 MB
Total 91 MB
Where are the remaining 100 MB?
Thanks
Saulo

128MB of TOTAL ROM = 64MB for OS/ROM (not available for user) + 64MB for file storage that is available for user
64MB of RAM = Used like RAM on a PC, Windows Mobile has to load itself into RAM in order to run so that's why you'll never have 64MB free.
In any case, what you are seeing is correct

Thanks a lot
Is there any way to oncrease the total availble memory?
There are several programs I never used, in the original package, such as
- file explorer
- pictures and video
- modem links
- sim manager
- terminal services
- power point mobile
- zip
- power excel
I would love to re-install a streamline version of the OS and have back 110 or 120 MB free usable memory!
Thanks
Saulo

nope, there's no way at this moment

So does this imply that little is gained by installing to the external storage card? I've seen both opinions on this.

if i use a memory card to store my songs and videos etc can i use botht the storage memory and program memory for the device itself. e.g. ringtones that have to be placed in the windows/rings folder and alarm and message tones which have to be in the /windows/ folder?

Dear All
Does anyone know how to free more memory?
Is there some special page on wiki (I cannot find) that explain how to tweak?
Or alternatively, is there a way to increase internal memory to 256MB.
At the moment, since most of my apps does not work on mini-SD, I need to increase internal memory
Thanks and waiting for any suggestions

ROM and RAM

What does ROM and RAM means related to the HTC TyTn ?
HTC TyTn ROM = 128 MB
HTC TyTn RAM = 64 MB
When you install application to the "Storage Memory", where will it be installed ? in the RAM ?
What are installed in the ROM ?
Where the default application from the provider (e.g. T-Mobile) are installed ?
Thanks!

The 128 MB of Flash ROM is broken into two parts:
- 64 MB for "Storage" (think hard disk space)
- 64 MB for "Program" execution (also called "RAM")
Programs reside in storage until they are activated (at which point they are also loaded into RAM). The amount of RAM you have available is what's left after loading the OS.
The carrier apps are also stored in ROM/RAM.

RAM is used to run applications. Its content gets lost on power off.
ROM (Flash RAM indeed) is used to store firmware, to install user applications and to keep data. Its content is kept even without power. "Extended ROM" is also a part of 128MB "ROM".
As I understand, HTC TyTN has NAND flash, and so no XIP and PagePool consumes a lot of RAM, though making things to run faster.
A good reading for beginners is here and here.
I don't like the tendency to call flash memory that is writeable as "ROM" (=Read-Only Memory). IMHO it provides a lot of confusions.

Very good explanation Lurker0, and both articles are worth reading for anyone!

Only 44MB of RAM instead 64MB

HI!
I have a Orange SPV M600 and I'm wondering why there is only 44MB of ram showed in memory aplet, but when i look at the product information there is shown 64MB, same goes for storage memory in product information it says there is 128MB but in memory aplet it says only 42MB.
Thanks for all the information.

Well, first of 64 MB on the package is always less on the system, just like with hard drives.
It is in fact around 61.3 MB because in real life MB is not 1000KB but 1024 and KB is not 1000 BYTES but 1024.
Then there is the part taken up by the system when its running .
As for storage, keep in mind that half of it is taken up by the ROM (the OS) plus 10MB is taken up by your extended ROM. (Which you can reclaim if you search for the reg settings in the WiKi)

what does mean UNLOECK AND USED FOR STORAGE in ur tagline?

prob means that he removed it to use it for storage space, the way he described to you...

Extended ROM is hidden by default and used by Cell companies to store their customization installation.
In my case (imate ROM) it contains Backgummon, eTrust and old Skype version.
Using reg settings found in the WiKi the ext ROM can be shown and the files can be removed / added through the file manager.
I use it for some stuff I do not want in main storage but can't put on SD.

where can i download the orange mpv600 rom?
i wanna try.
