Please my ignorance on this matter. I'm attempting to unlock a 3rd core my AMD phenom II x2 565 black. I've found a vid on youtube for the 555 which is very close in the bios looks wise but not the same. I attempted an unlock using the 555 vid with no luck. I've search and googled for intructrions. All I've found are useless reviews telling me the stats and how easy it is to unlock. I'm a lil' frustrated so please excuse my demeanor. I'm using an asus m4a79t deluxe board. Thanks in advance to any help given.
