Yep and I agree that its best to upgrade your BIOS to the latest edition.
Thats a pretty hearty processor youve got there as well. Yeah its a little long in the tooth but its a good overclocker and you might even be able to unlock a core or two. I had a X2 555 and it would hold 4 GHz all day long and unlock to a 3 core. 4th would unlock but wasnt stable. It should be fun to play with for a while.
