Hi, Sure I am missing something but in my BIOS my RAM only shows it running at 2133. Both XMP profiles show 3600 but the speed doesn't change. On CPUID it lists it at 1600 (which I presume is 2133 in reality). What am I missing? I'm on a B550 MSI Tomahawk with latest flash etc. Thanks in advance - it's winding me up no end!
