Hi guys. I was thinking of overclocking my already unlocked athlon II X3 (now phenom II X4 B45) when my aftermarket cooler arrives (Zalman CNPS9900 MAX). So just unlocking the 4th core upped the TDP to 126W (says CPUZ), now i was thinking of overclocking it and i want to how high can i go with it? Is it possible to reach 4ghz? As for the other specs you can see them but i'll just type the motherboard make and model here in the post: MSI 970A-G46
