I tried to overclock my intel core 2 duo E8400 @ 3,00 GHZ.my motherboard is gigabyte G41M-Combo with DDR 3 1333MHz (bottleneck to 1033MHz).i increased the FSB from 333 to 350,multiplier = 9.0 at volt which is my default voltage. the new frequency would be 3.15 GHZ but when i tried to restart my computer it refused to.i can't even get to the BIOs after doing this.i heard that someone overclocked the E8400 to 4GHZ but why can't i . did i do something wrong .
