No, it's not necessary to worry about hitting 4000MHz with a 5900x.

Your current build uses a ROG Crosshair VIII with a Ryzen 5900X and 4000mhz RAM. The recent video mentioned Linus's All White Build, highlighting performance limits of AMD's Infinity Fabric when running at higher ratios like 1:2. You're considering whether to replace the RAM with slower speeds or switch to the NEO series. The Crosshair claims it can be overclocked up to 5000MHz, but the CPU's Infinity Fabric is likely the bottleneck. If you boost the CPU speed, will your RAM speeds drop? This could impact stability and longevity of all components. Since you haven't built the PC yet, think about how much this will influence performance beforehand. The 4000MHz was chosen for those specific speed targets—adjusting it might affect them.
