while i tried to make int array[1000][1000][1000] compiler gave error, 
with array litlle bigger than [510][510][2] compiler halts. why so? if i 
want to use arrays such big, do i have to use malloc?

Maybe because static arrays are created on the stack, your application
doesn't have enough stack space? Creating a dynamic array might work.

  int[][][] X;
  X.length = 1000;
  for(int i = 0; i < X.length; i++)
  {
    X[i].length = 1000;
    for(int j = 0; j < X[i].length; j++)
        X[i][j].length = 1000;
  }

Or maybe you can create one dimensional array and do your own indexing...

  int[1000*1000*1000] X;


Just out of curiosity, and this is not a criticism, but why does one need
such large arrays in RAM?
