Kingston HyperX Red - 8GB (2x4GB) DDR3 1600MHz Memory Kit Review (KHX16C9B1RK2/8) - Benchmarks - AIDA64
AIDA64 is a 64-bit benchmarking, monitoring, and diagnostic suite which proves useful for a large number of applications. The benchmarking side of the suite allows testing a wide range of CPU performance, disk performance, and for this particular review, memory benchmarking. For more information on the AIDA64 Extreme Edition we're using for our tests, see Finalware's Website.
Memory performance will be nearly identical for any two sticks at a given clock and timing setting. The trends here are similar to most kits, where the bump to the next frequency step will provide a more substantial increase in performance than going to a second higher step. The reason for this, as we mentioned, is that the timings tend to have to be relaxed enough to offset much of the frequency gain (and you're seeing a smaller percentage change from the already-higher setting). With that said, the 1866 MHz overclock delivers a performance increase of about 20%, which is also consistent with the increases we've seen in 2-step overclocks in other kits.
