BoT

what brand laptop is it? i would go with bios options over software anyday.
if there are no oc options in bios, i'd probably not do it.
i am not sure what the load was when you took the everest shot but the cpu temp showed already at 62 degrees. getting temps under control is paramount for "save" and successful overclocking but hey, i'd shy away from laptop overclocking anyway.

rivatuner is mainly for video card overclocking and works better on nvidia then ati
setfsb is a pretty good program to overclock. it has a learning curve thou and requires at least some basic knowledge of overclocking. this tool can also cause damage to your componants as all overclocking can. use with care
