That is correct people, there is now a new way to unlock the 4th core on AMD's Phenom II X3, and that is by going over to the green camp. What do you need? You need the GIGABYTE GA-M720- US3 motherboard using the Beta BIOS F3F, along with 4th week 2009 AMD Phenom II X3 (batch code 0904). If you are one of those lucky users with this combo of motherboard and CPU, head on over to HWBOX.gr now! Note that other motherboards and chipsets may work as well.
