Do you know if the board can physically support the CPU?

Do you want to run the board with a mixed setup of both CPUs?
(i have no idea if that works, but i would bet on: NO)

and to 65nm quad cores

Possible, it is unclear if the microcode patches are needed, but with them it 
does not work.

Is your shanghai a CPU from a store? (= no engineering sample)

The terminology is that the northbridge is in the CPU and the chipset is the 
I/O hub.
