Avec un Ryzen, les FCLK (fr\u00e9quence de fonctionnement de l&#8217;Infinity Fabric), UCLK (fr\u00e9quence du contr\u00f4leur m\u00e9moire) et MCLK (fr\u00e9quence m\u00e9moire) fonctionnent id\u00e9alement avec un ratio 1:1:1. Mais le FCLK ne peux pas monter \u00e0 l&#8217;infini pour suivre la fr\u00e9quence des barrettes DDR4 les plus rapides ; il plafonne \u00e0 1800 MHz (id\u00e9al pour de la DDR4-3600), m\u00eame s&#8217;il est possible de l&#8217;overclocker avec plus ou moins de succ\u00e8s. Pour utiliser de la m\u00e9moire plus v\u00e9loce, il faut alors d\u00e9synchroniser l&#8217;Infinity Fabric du contr\u00f4leur m\u00e9moire et de la m\u00e9moire elle-m\u00eame, et utiliser un ratio non-optimal augmentant certaines latences.
