Updated to 1809, for the past two days. Update failed after first reboot during installation. Studied the fault code and decided it might have been the OC. I defaulted the BIOS and started again and 1809 installed.
Only one issue, and is actually a repeat from initial 1809 initial install a month or more ago. Samsung Magician Over Provisioning is broke and I can no longer set an OverProvision.
