[skipper847]

Hi all new here and to gigabyte motherboards. I got a new Pc 2 weeks ago and is running fine and fast but could run even better as all bios is set to default. My memory is RAM0336 Corsair Vengeance Low Profile 8GB Kit which is 1600mhz but in the bios it shows its running at 1333mhz. In the bios in 3d veiw i have set now the E.M.P to profile 1 and pressed save. Now the PC is alot faster and websites loads instantly where be for they took half a 2nd more which was i noticed.  If altering the XMP do i have to change anything else such as voltage or is it alright leaving it as default?. Is there anything else i could change what i dont have to change the voltage to?.
