wow so what about previous posts claiming that there should be around 196mb or ram?
say its only 128mb ram are we going to be affected by that? say not being able to play 3d games or even say compass is slow coz of lack of ram?

 

[Rastaman-FB]

someone did some checks early when i made this statement last week as people believed it to be 192 but they found it was 128

dont know why samsung have done that or what implication it has as most devices for android now house 288

people made assumptions on what the hardware was as most if it is similar to the g1/dream

gsm arena and many other sites also show this as being 128mb ram

Hmm no it is 192mb. There's 128mb ram external to the MSM die, and 64mb internal to it. I don't know how whoever it was checked, but maybe they only saw the 128mb bit.

Its _definatly_ 192mb, i've checked myself.

what is caching used for if not keeping libs in RAM? preload all of them when you're already low on resources doesnt sound like good idea.

i've seen many distros, back when 64mb ram was very much and never seen anything like that.

This seems to suggest that mtdblock1, 2, 4 and 5 are part of the flash that the system uses to store the os on (As suggested by the naming convention). This is separate from the 8gb built-in memory. So there is no ram mount here.
