run QDR 1600 and ram at 800 or 1066Mhz, might need a small increase in chipset voltages for the Nb and a bit more Vcore for the CPU , estimating around 1.2Vcore if you got a nice CPU

Just adjust CPU Vcore , FSB QDR and Ram speed and voltage, leave rest on auto for the voltages, should work out of the box...

There's no need to mess with HT, or follow this guys stuff, covers it all ::
