MaxxMem2 PreView is a handy, free program to rate memory performance. It can be downloaded over here.
The 2133MHz Viper 3 memory offers the best overall MaxxMem2 performance when overclocked. The 2400MHz G.Skill TridentX and 2133MHz Patriot Viper Xtreme Division 2 kits achieve slightly better memory copy results; whereas the overclocked Viper 3 kit shows chart-topping performance in both the memory read and memory write tests.
A healthy latency decrease was provided by the higher frequency of our 2261MHz 12-12-12-27 overclock.
Nice looking memory, so much of a selection now at this speed, it has to be all about the price. unless you were aiming for overclocking. The low profile samsung memory has to be the b est for overclocking, some people have got it to 2700mhz from 2,133
