Hey All. I recently built my first computer (start to finish, no piecing together over time like I always did). I have the ECS A780GM & Phenom II X3 720. I currently have it OCed to 3.4GHZ on stock fan/heatsink. I want to unlock the mythical 4th core to see what's going on. Is there any way to change my ACC settings on the 780/700 chipset or would I need to upgrade to the 790/750 chipset? I like my current board A LOT, but would be willing to part with it for a new board that is "guaranteed" to open the 720's 4th core. Feedback?
