I bought this 16x2 = 32GB of RAM from MDcomputers. This module uses Micron memory IC and it overclocks really well too. Mine is running stable at a relatively tight timming of 16-18-18-18-36 with super tight sub timmings all running at a clock speed of 3800 @1.35v. Those who want even higher clocks say 4000mhz+ is easily possible provided you loosen the memory timmings little bit and bump the voltage towards 1.40-1.45V which is still a safe overvolt. One can buy this Corsair RAM with eyes closed as it offers a nice balance in price and performance.
