The Corsair is faster memory, however I have run 16GB of the 1333 HyperX Blu above for over 12 months now. My PC is used for home working and it's switched on well over 12 hours per day.
The HyperX Blu I ran overclocked at 1500mhz at 1.3v (yes 1.3v) with stock timings. I am now running the memory at 1550 at 1.4v as recently overclocked little more.
The fact the HyperX Blu ran so quick at so little voltage shows it's very high quality memory. Computer is rock solid stable.
