Wow I really suggest you turn your overclock down and voltage levels now (if you are using anything higher than ~1.65V). Intel's specified limit for memory voltage is 1.65V, 1.7V is fine but 2.5V?? Seriously you'll fry your Core i5's memory controller in a few weeks or months. Keep the RAM speed back down, there's not much of a difference between 1600 MHz and 1950 MHz. Otherwise for voltage keep it at 1.65V or the maximum that G.SKILL recommends.
