Now, this overclock is with the stock Intel HSF included with the socket 775 CPU. I started upping the FSB in small increments, waiting for a "BSOD" or some strange behaviors in performance. I was very surprised but the only system changes I noticed were increases in temps. I used the program AiBooster provided with my ASUS board to overclock. I verified all overclocked speeds with CPU-z. As you can see below, my system was able to reach 4.0Ghz with no problems.
