The NBIO area holds the overdrive features offered by gigabyte. For whatever reason.. P4e bios I cannot see them. I know the p4d bios can but currently I cannot and I think it's my bios revision. Anyone else with P4e who can check? It should be in the Peripherals section. Under AMD CBS section.. you should find an option for NBIO which leads to Precision Boost Overdrive configuration. Setting this to manual and 10X is supposed to yield some performance gain.
