A CPU swap from Ryzen 9 5900X to 5800X3D silently reset RAM from XMP/EXPO speeds back to slower JEDEC defaults, going unnoticed for weeks. The author shares how this is a common but overlooked behavior — BIOS updates and CPU swaps can both revert memory settings. The impact was subtle (lower 1% lows in competitive gaming) but real, and the fix was simply re-enabling XMP/EXPO in BIOS. The takeaway: always verify XMP/EXPO is still enabled after any CPU swap or major BIOS update.
