You should be able to get a few hundred mhz out of that chip pretty easily, especially with such fast RAM. As you overclock, go slowly. Bump your FSB up by smally increments, 5-10mhz, and check temperatures and stability. If temps are hitting over 50C at load, you should probably stop. Also, after each bump in speed run a program like Prime95 (
