We received new kits from five manufacturers for this test. Crucial and Kingston sent us respectively five and six DDR4 sets, while G.Skill and Team sent us one set each that were both mainly aimed at overclockers. We also included a new kit with LED lighting from Corsair.
All memory modules in this test support XMP 2.0. This means you can apply the correct settings in one click via your BIOS and therefore you don't have to adjust the clock speeds and timings manually. Some motherboard manufacturers even notify you of this function if you enter the BIOS for the first time after building a new PC.
A large part of the tested modules is mainly compatible with Skylake, which means you can easily achieve higher clock speeds for the memory. The Intel X99 platform are a bit pickier though. Memory kits up to 3,000 MHz usually work without any problems, however if the clock speeds go any higher you might run into some problems.
We test DDR4 memory with the ASUS Maximus VIII Impact motherboard and an Intel Core i7 6700K processor. The clock speed and uncore of the processor are set at 4 GHz, with turbo mode turned off. In the graphs we compare the kit with the sets from our last big test. We only tested two modules if we were testing a quad-kit, since the Impact only has two memory slots.
Initially we run our tests at XMP settings, in other words the standard speeds of the modules. After that we overclock the memory as much as possible with XMP timings and voltages. We use the memory multipliers to overclock the modules. Then we try to achieve higher speeds by upping the voltage. Lastly we also try to optimize the timings to achieve scores that are as high as possible.
