Oppsss, sorry, I have tried to allocate using pointer, direct array 
var and pointer to type array

a)
var
     p : pointer of byte;
...
     GetMem(p,100000000); //100 MB
b)
var
     a : array[1..100000000] of byte; //100MB
c)
type
     a = array[1..100000000] of byte; //100MB
     pa = ^a;
var
     p : pa;
...
     GetMem(p,sizeof(a));

Also tried changing 100M of byte with 25M of cardinal but got the same error.
