A year of 7 ago I owned an IPAQ 3780. On that device you could change the amount of memory and storage. More memory and less storage or otherwise.

According to the HTC website, the HTC diamond has:
ROM: 256 MB
RAM: 192 MB DDR SDRAM
Internal storage: 4 GB

Most roms with TF3D enabled have around 60MB ram left after booting.

Still it makes me wonder why we can't change that amount by making the internal storage smaller and add it to the memory. The device comes with a 4GB internal storage, so what is the point of having a large 'standard' storage. It is not that difficult to move pointers to 'my documents' to 'internal storage\my documents' etc.

But asking this, i think Rom builders already know there is a reason why the RAM can't be enlarged.

Please enlight me with the answer or start discussing how to build such a rom.

That's impossible, absolute different technologies in RAM and storage.. And btw, 64MB of RAM is used for video acceleration, and 60MB goes to Windows Mobile..

In your old Ipaq storage and memory were the same. When the battery was empty all your data was lost. Only the os was kept in the rom. Since Windows Mobile 5 all your saved data is in the rom - and cannot be lost when the battery is empty.

so you can not enlarge the rom by decreasing the ram - its completely different hardware.

Yep, those were the days of WM3 where that was an option to the end user. Even if such an option existed today, how many would actually subtracted the storage for more ram? Well, every user is different. The way I use Ram vs. Rom on this device is basically straight down the middle.

To each is own! The trick here is to work with what we have. I think we aren't doing to bad at all!

Oke, that answers it.

Though 64MB for video acceleration is a huge buffer for this 640*480 pixels screen. Stealing memory there?
