Many E7500's will reach 4 GHz, just not with a G41 motherboard.You will have difficulty reaching past about 3.8 GHz or so because of FSB limitations. It will be difficult to push the FSB freq past about 350 MHz.
Using stock cooler will limit you to about a 20% overclock.
After that, you will need a better cooler and you will need to learn how to use the BIOS.
yeah - I'm running it at 3.5MHz with stock cooler now.
