Patriot Viper 2 Sector 5 DDR3 2GHz @ Bjorn3D

"To take advantage of the full potential of LGA 1156 Core i5/i7 memory your going to need a good kit of low voltage DDR3 capable of giving you the performance you want and stay under that pesky 1.65v limitation imposed on LGA 1156 CPU's. We say ' imposed ' on CPU's because it's the memory controller on the CPU that needs the RAM to stay under 1.65v to prevent damage."
