Notes

The simplest way to examine the effect of memory speed and timings is to look at the relative performance of the 2,133MHz and 3,200MHz kits.

Overclocking

We've chosen three arbitrary speeds and timings in order to evaluate the overclocking potential of the Corsair modules. Voltage was increased to 1.45V.

  3,333MHz
(16-18-18-36-2T)
3,400MHz
(16-18-18-36-2T)
3,400MHz
(17-17-17-39-2T)
Corsair @ 1.45V

Jumping up to 3,333MHz is easy at the specified timings but going any higher is problematic. The precise reason for this is unknown - it could be due to a memory ceiling or inability of the integrated memory controller on the Core i7-6700K to service higher speeds.
