Yearly this year AMD launched its triple core (X3) Phenom-II line up. It was not long before many overclockers around the globe discovered that Phenom-II tri-core processors were actually quad-core processors, in which the fourth core was just disabled.

It was not official till MSI came up with an official news bulletin this month.

X3_to_X4_01

MSI now allows X3 users to enable the fourth core with a (virtual) switch under its BIOS. All Phenom-II X3 users can upgrade their CPUs to X4 given they are using a supported board and BIOS. Below is the list of given motherboards, which supports the upgrade / hack.

Infact this mod / hack /upgrade / overclock works with most of the AMD 785 / 790 chipset based board. You just need to play with the option called “Advance Core Control” under BIOS option CPU features and control.
