Yes, the bios has limited settings for use with K chips; see the service manual. No LLC and a fixed xmp1 of 2933. Alienware Command Center has pages for fans/monitors, win 10 modes, and O/C, with two preset O/C profiles of X46 non-xmp and X48 xmp1, or custom profiles to X50. Also has a stress test. Lacks some settings and limited ranges for others, probably to minimize potential damage. Big Brother Is Watching You.
XTU works in place of ACC's O/C page, but profiles with avx different from 3 and X settings above 50 don't survive reboot; the X51 setting I am using still looks right, but is not in effect, and requires resetting.
