Chain 8 has a higher freq than 6 and 7.

Would there be a reason why someone would have modified the unit to run higher on one hash board?

Can I change this one board back to match the others?

Unit runs fine on pools

Solo via BFGMiner on Stratum proxy it restarts every 15 minutes - Also solo R/T hash rate is 13.5 while AVG hash rate is 4x that around 53 any ideas why that would be?
