You just need to go into the BIOS and up the Voltage setting there ( most MOBO's can change it in .05V increments so you want to add .15V to your default of 1.5V) Since it is 1600MHZ. you will also need to change the speed and timings ( Most MOBOs will default to 1333Mhz at fairly loose timings - so that the MOBO can at least get into the BIOS even with slower RAM) - but to get the correct performance from what you bought those settings need to be adjusted manually otherwise you will be running at slower speed and timings and not getting the performance you paid for !!
