Gskill Flare X 5 2x16GB EXPO 6000 CAS36 (Samsung) kit I have has issues on both a Gigabyte B650M Aorus Elite AX with both a 7950x and a 7600 .. and on an ASRock B650E Steel Legend with the 7950x. Booting with EXPO enabled is hit and miss. Once I can finally get it to boot into Windows with EXPO enabled, it's as stable as a rock though
