"Patriot tries to make the choice very clear with one of the fastest memory kits currently on the market. Specially designed for the high end 790i chipset, the Viper PC3-16000 kit sizzles at a stock speed of DDR3-2000. You read that right, 2000MHz! It also weighs in at 2GB (2x1GB) with timings of 9-9-9-24. Sporting an nVidia inspired bright green paint job, there is no mistaking these sticks among the sea of RAM choices available. If you are looking for a memory kit that can help push your system to its limit, you'll definitely want to keep reading as HardwareLogic throws these Vipers on the test bench to see what life at 2000MHz is really like."
