EVGA 680i Overclocking BIOS Settings

Nemisis, why have you set your sata spread to downstream? The NV guide advises disabling all the spread spectrum settings when OC'ing. Does it offer some sort of protection against data loss? Just curious.

so ya my board hits a wall at 425 wich is really BS for a 250$ board.
having a 6550 doesn't help either. even with the p31 bios its still no go.
my mushkin seems to do fine with the board.

im really tempted to sell the board and get something els

Spread Spectrum is a setting that reduces EMI being emitted from electrical components. This is done by varying the frequencies that are being transmitted. Turning the setting off allows the device to work at a fixed frequency which increases stability. Spread Spectrum is commonly referred to in wireless and radio devices.
