I know that the 875P chipset does not officially support 400Mhz-bus processors, but will this mobo refuse to work at all if a 1.6 Northie is installed or can it be made to work anyway? My 1.6 Northie has been running with a 533Mhz bus speed for the past 2 years overclocked, so I know it will work at the minimum supported 875P speed. But will the mobo refuse to boot up and complain with the 1.6 installed?
