Looking here:

and here:

It looks like your board will only handle 95 watt TDP and the CPU is 105 watt TDP. Also, this CPU is not on the list of compatible CPUs for this board. In looking at the pictures of the board itself, it looks very anemic in power phases. My guess is that the board is already at it's power limit before your attempted OC.

***Edit*** I also see that the built in video takes system RAM. It is also possible that any fsb OC could foul the GPU.
