    You can run CPU-Z and check the mainboard tab to see what BIOS version you have if you are up and running in Windows. The second BIOS listed is a Beta BIOS and likely doesn't ship with the motherboard.

    You can unlock additional cores of the AMD 550 BE in the BIOS:

    Advanced Clock Calibration
    Allows you to determine whether to enable Advanced Clock Calibration when using an AMD Black
    Edition CPU. It is recommended that you enhance heat dissipation for the CPU VRM area if you
    enable this function.
    Disabled - Disables this function. (Default)
    Auto - Lets the BIOS to configure the settings to defaults.
    All Cores - Configures Advanced Clock Calibration for all CPU cores.
    Per Core - Individually configures Advanced Clock Calibration for each CPU core.

    Value (All Cores)
    This option is configurable only when Advanced Clock Calibration is set to All Cores.
    Options are: -12%~+12%.
    Value (Core 0), Value (Core 1), Value (Core 2), Value (Core 3)
    This option is configurable only when Advanced Clock Calibration is set to Per Core.
    Options are: -12%~+12%.

    AMD OverDrive Utility (Provides insight to monitor your system settings)

    Be prepared to clear the CMOS if unlocking the additional cores of the CPU causes the PC not to boot up.
