The performance of AMD's Ryzen chips depend heavily on the frequency of the RAM installed thanks to how Infinity Fabric works.  TechPowerUp decided to see how sensitive Intel's Coffee Lake processors are, testing the performance with RAM speeds from 2133MHz up to 4000MHz as well as modifying the timings.  Not to spoil the results for you, we can reveal something else their tests revealed, G.SKILL's Trident Z DDR4-3866 16GB kit is impressively flexible, they were stable at 15 different combinations of timings and frequencies.  Check out the full results to discover the sweet spot.

"We take a close look at memory speeds, latencies and command rate on Intel's latest Core i7-8700K with Z370. Scenarios tested include fail-safe 2133 MHz, the platform default of 2666 MHz and overclocked memory speeds from 3000 MHz to 4000 MHz – at various timings."
