IP35 pro overclocking

Ok I just switched from the rig in my sig to and IP35 pro, Q6600, 8800GT, corsair 520hx, and 2x2 gig G.skill DDR2-1000. i've read the c2d/c2q overclocking sticky but i have a few questions on this board. I easily got 333x9 3.0ghz, but i can't reach 350 FSB and I do not know what all the different voltage options in the BIOS are for. I'm used to NF4 939 boards where it's pretty much Vcore and base clock adj. I did test with a 6x multi and ram @700 so it's not the cpu or mem holding me back.

i'm currently running the same basic setup except i only have DDR2-6400 (not a problem though, its not even running at stock until i hit 400 fsb). My chip has a VID of 1.3250 and i knocked it up to 1.3450 and i'm now running 356x9=3.204Ghz. Also, don't install uGuru. i wasn't even using it for overclocking, just monitoring voltages and it still held me back heavily.
