If you can’t change the FSB of your mainboard but wan’t to overclock this CPU with 133 MHz FSB you have to cover up pin A14 with a adhesive tape or nail varnish to pretend an 133MHz CPU. It’s easy to locate this pin – over these pins are some small numbers like A1, A73, A74, A121.
just count from the left Pin on the frontside 14 steps to the right pin.
