AMD Ryzen AM4 processors override the Plug N Play feature of Kingston FURY Beast and Impact memory, forcing them to run at slower speeds or timings out of the box. To enable the advertised speed, Profile 1 must be selected within the BIOS. This will force the Plug N Play speed and timings. Note that not all AMD Ryzen processors will support all speeds. Check with your motherboard manufacturer for a list of tested overclock speeds.
