I activated XMP in UEFI, and the available profile claimed to bump the bandwidth of my hardware (two 8GB sticks) from stock 1600Mhz to 2133MHz. In the OS, software like Speccy, as well as the plain old command-line, report a speed of 1600MHz (e.g. CPU-Z = 800MHz Bus = 1600 MHz). Does that mean the XMP isn't working?
Tangentially, why does activating XMP change the SATA protocol from AHCI to RAID? I had a few minutes of panic dealing with a master boot error until I noticed what had happened and restored the setting to AHCI.
