At a speed of DDR3-2400 timings of 11-13-13-30 @ 2T are more than impressive and hint at the overclocking potential of these DIMMs.  They also come with two XPM settings, the one just mentioned which runs at 1.65V and a 2133 MHz mode which runs at 1.6V and similar timings.  Once TechPowerUp got their hands on the DIMMs they managed to hit 2634 MHz and tighten up the Command Rate to 1T.  Keep in mind those pretty heatspreaders may make your life difficult if your motherboard is crowded around the socket and your heatsink doesn't have much clearance.  That exact kit does not appear at NewEgg but a very similar 16GB kit does.

"A rabid animal hungry for food, the Kingston HyperX Beast stampedes into the overclocking scene, ripping through our benchmarks like no other. Clocked in at 2400 MHz out of the box, these beasts are ready to take on whatever you want to feed them."
