Kingston 10th Anniversary HyperX 16GB 2400MHz Testing:
Memory is often hard to separate from one kit to another in gaming, but when it comes to number crunching and computing, some memory provides an extra boost in comparison. To see just what kind of performance this kit has to offer, I will be running the modules through a series of benches to see just how they compare. There will be 8GB and 16GB kits ranging in speed from 2133MHz - 2400MHz, tested at native speeds as well as overclocked. Overclocking of course will be dependent on exactly how far the testing rig will allow, but I'll push it as far as I can. The testing setup used for these benchmarks is listed below, where Turbo Boost has been disabled to eliminate uncontrolled clock changes that may skew the results. The CPU will be run with default Boost clock speed of 3.9GHz for baseline testing and bumped up to 4.2 GHz for OC testing, or as close as possible to that speed. All current updates and patches are installed for Windows 7 Professional 64-bit and the latest driver for the NVIDIA GTX 770 will be used.

Overclocking on Intel Haswell processors is quite a bit different from what we are used to in the last few generations, where the CPU clock speeds did not influence the clock speed the memory controller could handle. Entry to Haswell memory overclocking 101 shows that while the CPU may handle a nice overclock of up 4.7GHz to 5.0GHz on really impressive examples, the memory may not scale up past 1866MHz or 2133MHz at those CPU clock speeds, even though the memory modules are rated much higher. 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. That being said, keeping the CPU as close to 4200MHz was imperative if I wanted to push these HyperX modules from Kingston.
During my testing I found that while the kit ran flawlessly at its rated speed of 2400MHz, they just did not offer a whole lot of headroom above that, even when pushing 1.75v+ through them. Seeing how running a 125MHz or 166MHz strap is a bit easier on the memory controller, I swapped to the 125MHz divider and started upping the frequency up a little at a time until reaching the maximum clock speed on the HyperX modules. I left the memory sub timings alone and controlled by the board, adjusted the primary timings to 12-13-13-33, adjusted the DRAM voltage to 1.70v, started up again, and finally reached 1260.2MHz or just over 2520MHz for a 120MHz gain in clock speed. That represents about a 5% gain from just testing and tweaking. What I found was that the Kingston HyperX 10th Anniversary modules performed well even with the boosted clock speed. The low profile heat sink makes sure there are no restrictions to the CPU cooling solution used.
Maximum Memory Speed:
The maximum memory speed for each set of overclocked modules is indicative of how well the modules ran on this test system. As such, your results may differ in either a positive or negative way based on the capabilities of your hardware. In other words, your mileage may vary!
