The OP said earlier he has an Intel D975XBX motherboard.  Intel boards 
are very conservatively engineered, and don't have tweaks for 
overclocking, out of spec memory voltages, or any of the rest of that.   
They just work, if the parts meet their spec.  If the parts don't meet 
the spec, then all bets are off.
