Just a little something I thought I should share with people. The Dangerden 775 RBX block does not clear the caps on the Gigabyte P35-DQ6. You need to file a tiny amount of the copper away from the edge of the waterblock to get suitable clearence. Only takes about five minutes careful filing to do.

I should be up and running in the next couple of days, just waiting for the waterblock for my X1950XTX.
