has anybody tried to overclock with a GA-P35C-DS3r gigabyte board?

i'm trying to get some extra power out of a e4300 with an arctic freezer 7 pro on top, but can't seem to get it to work. i've clocked a e4300 at 3.15Ghz on an Asus P5K board with the same cooler, and it was a piece of cake.

but for some reason the bios on the gigabyte board just won't do what i want it too

anybody got any suggestions? i'd be very happy to try any ideas. thanks
