MOBO not letting me confic ANYTHING

i have this as my stock CPU stuff:



and i go ointo my BIOS to change up some stuff, and it wont let me edit ANYTHING. EVERYTHING that controls O/Cing is greyed out.

note: model=ASUS A7V-400MX

this is only a cpu to mess around with (refer to my signature)

thanks. also, if any other mobos do this...why is it?

did you enable the overclocking feature (if there is)? Maybe try updating the bios.
