It could be if its the only thing thats not default.

Btw I haven't had any luck at all overclocking this board I think I am either doing it all wrong or I cant get a result from any clock other than default settings... all I get is black screen and have to reset bios to defaults to get back in, im sure its me doing something wrong, so could you put together a quick procedure of how best to overclock on this board to preserve my sanity?

Cheers
