Test Rig
For our tests, we used a new test rig which is comprised of a MSI MPG Z390I Gaming Edge AC Motherboard, along with an Intel Core i7-8700K at default clock speed of 4.3GHz, as well as 16GB of TeamGroup Xcalibur RGB DDR4-4000 ram in dual channel mode.
All tests were conducted at default clock speeds at a resolution of 1920×1080. High or Ultra settings enabled.

BIOS Setup
We used the MSI MPG Z390I motherboard … Setup in the BIOS was super easy. All I had to so was to select the XMP profile and made sure the Memory Frequency was set to 4000 MHz. All other settings were left untouched on AUTO.
CPU-Z and SPD Information
CPU-Z reports the DRAM frequency at 2015 MHz which is about right for DDR4-4000. Memory timings is also correctly reported at 18-20-20-44.
Although the memory timings seem to be quite high, the increased speed of DDR4-4000 should counter balance any latency. And of course, higher memory speeds means higher overclocking ability.
AIDA64 SPD Info
Memory chips are made by Samsung and supports XMP 2.0 profiles. Memory speed is DDR4-4000 @ 1.35V
