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

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

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

Operating system is  WinXP SP2. AthlonXP 2000+ and 1.25 GBRam
