Not sure if it's a problem with the 1660 Super or what but PPD seems way down on these WU's. Getting less than half what I was usually getting at only ~400K-ish PPD . Been considering a 4060 for power draw/performance reasons for the farm but this MSI 1660S is very quiet so it's not unwelcome. That is the performance my old 1060 was getting during the annual TAAT challenge but it's not really economical to keep it in the line up if this continues.
