I have an A7N8X DLX Motherboard. I have 256 mb of 2700 ddr ram. I tried changing the FSB to 166 mhz from 133 and changed the myltiplier from 12.5 to 10 so it was 10x166=1666. but when i booted up it said CPU speed incorrect please correct it. I believe that you dont have to unlock the proccessor with an A7N8X mother board. why didnt it work.
