Dual-slot configuration [Auto]

When set to [Auto], the BIOS automatically sets the configuration for
either single or dual graphics cards. Configuration options: [Auto]
[Single Video Card] [Dual Video Cards]

If you set this item to [Single Video Card], you will not be able to enable
the Crossfire™ function even if you installed two Crossfire™-enabled
graphics cards. For optimum performance, we recommend that you keep
the default setting [Auto].
