Latest working BIOS, updates and drivers were used at the time of the review. Each test was conducted at least three times for accuracy. UEFI defaults are loaded for stock settings and XMP profile is loaded.
Overclocking the Kingston HyperX Fury kit was fairly easy. While I could not just change the multiplier and jump from 2400MHZ to 2600MHz, I was able to bump up the CPU gear to 1.25x. I kept the CPU at the stock speeds. In order to do so, I dropped the multiplier on the CPU to 24 and the turbo to 28 which maintained the stock speeds of the Intel i7-5960x at 3.0GHz/3.5GHz. I also manually set the uncore for the CPU. The goal was to only overclock the memory, and not any part of the CPU. I also bumped up the voltage from 1.2v to 1.4v. With these settings I was able to hit 3000MHz 16-18-18-44 CL2 with this kit, but could not go any higher. Any attempts at this point to either increase the speed or tighten up the timings would send the motherboard into a reboot loop.
After I finished up the overclocking tests, I wanted to see how far I could tighten up the timings. At 2400MHz I was able to drop down to 12-15-15-33 CL1 at 1.3v. You’ll notice in the performance graphs this will be labeled as 2400MHz – BT (best timings). My attempts to further tighten up the timings would result in a Windows 8 Blue Screen.
