Patriot Viper 3 Black Mamba PC3-19200
 

OverClockers Club has 16GB of Patriot's Black Mamba PC3-19200 strapped to the test bench for a few rounds of benchmarks. What I found on both of my CPUs was that anything greater than around 4250MHz on the CPU would not run the memory at 2600MHz or higher. The G.Skill Trident comparison modules would run just over 2600MHz at 4.4GHz, but the Black Mamba Viper 3 modules would cause a lockup at that speed. After plenty of trial and error, I was able to push the modules up to 2800MHz by relaxing the timings to 13-15-14-35 and letting the motherboard assign the rest of the parameters.
