Does different brands of RAM in a workstation make problem in its performan

I just bought a HP 8710 mobile workstation with 2GB 667 200 pin DDR2 ram. I’m going to upgrade it to 4GB and at the moment just CORSAIR Valueselect is available in my region, which is of course have same specifications with genuine HP module. Does different brands make problem in WS performance or I am worry for nothing?
