I want to try overclocking this board and don't understand what\njumperfree mode is. I can't find any jumpers to change to go from auto\nto jumperfree. When I change cpu speed from auto to manual, the cpu\nmultiple\nspot is greyed out. Does this mean I have a locked processor and can't\noverclock it? It's a Northwood 2.4\nGhz. Please excuse my stupidity but I'm just beginning to learn about\noverclocking. Any step by step help would be appreciated.
