Hey guys! Nice to see others getting 4.3 - 4.6+ ,depending on circumstances, with air! I was a little surprised at first when I was first able to get my rig to 4.7 on air, but later it turned out to be too much b/c under full loads doing distributed computing I ran into stablity issues! But so far 4.5 is doing well(1.38v)! And I enjoy reading this thread too, since I have joined up!
