Will OC remain? Will gains be better if I close it after applying my OC?

When the 30 series first came out I was getting like 700+ points lower in port royal with x1 open. Since then it's supposed to have been fixed but I still keep it closed. When benching I set fans to max, set clocks, voltage, and power, then close x1.
