I had the EXACT same problem. I left my machine running for 30 minutes after turning on EXPO after hearing about “training”. Hard reboot, CPU code error… uh oh. Clear CMOS, boots again at 3000mhz. Decide to install Windows first, and then after I turned EXPO back on and have had zero issues at full rated speed. Even ram memtest to be sure. Im running a MSI MPG x670e Carbon Wifi for what it’s worth.
