Here are my specs

All I have done is set it to xmp and put it to Msi unlimited settings instead of intel default settings.

I also enabled slow training and disabled memory fast both when oc fail so the oc does not get reset when I boot up. I’ve gone a week with these settings then today when I boot up it took longer then normal and was stuck on a black screen for a second until it eventually loaded into my desktop. Went to bios to go do a cpu oc and noticed my ram is set back to default.

I did not change anything in bios and I did not update bios. What happened?
