To be honest, you didn't go very far, 1.225 is about the highest undervolt for these chips I've ever seen, on an 8320 with 1.32V stock voltage you should aim lower for the 1.150-1.200V range. Mine can do 1.156V with all 8 cores enabled on 3.5GHz and I even got it to work at 1.118V by going one core per module ways (which, if anyone is even interested, makes it nearly capable of running passive on a Mugen 4 heatsink in a system without a single fan in it
), going lower makes it fail to boot. As I said, you can't damage the CPU/mobo by reducing CPU voltage, you can only extend component life.
By the way, which temperature gets to 65C, CPU itself or something else? In that AIDA64 pic you posted, my guess is that "Motherboard" value is the Northbridge, "CPU" is actually the socket, and "1. CPU / 1. Kern" is the CPU temperature, my 970A-UD3 has similar designations. My guess is the socket.
Also, as some have already said, put a fan to blow over the VRM area (between the CPU and rear I/O) unless you want to blow up the board, it's a must on un-sinked 4-phase boards and 125W CPUs. And one behind the CPU socket, to make sure the socket doesn't overheat either.
