Many want to use 4GB of memory and not the 2*2GB combination. Many memorycontrollers don't like this as it seems. Some motherboards does run it quite good.
I'm not an expert in Intel motherboards. I wanted the GA-X38-DQ6, but it fails with 4*1GB hardly with Ballistix PC8500. The ASUS Formula does some better, but really enought?
What is the best chiose? Maybe wait for the X48? The make motherboards with 4 DIMM's, but not to use them
