That q6600 B3 will do 3.6 on air but needs more voltage than the G0.
you don't have to worry so much about the termination voltage or north bridge as you would the 45nm quads so you can push that higher if you like the 8X multiplier and higher FSB , otherwise I would use that 9X and go for 400 FSB ,leave the ram at 1066 pushing the nothbridge to 1.4 - 1.45 and FSB as high as 1.36(or a little higher )
your pll can come up a little more also.
as long as your cooler can remove the heat from the CPU you can push the cpu to 1.45 - 1.48 and drop it down until you loose stability ..raising it up small increments at a time until you regain stability.
you can go after the ram later
