Good news today, the temperature dropped by 7 degrees, but the DH rose in more than one device by 30%. What effect does this have on the hashrate?
DH = Average error rate, it shouldn't be more than 1.5%, max 2%, it has been a while since I run any Avalon (never liked them, didn't have good luck with them, maybe because I bought them used/abused, but ya) IIRC the GHSavg which is the hourly rate will show the actual hashrate the unit runs at after taking into the account the DH, DH and HW are usually caused by incorrect voltage/frequency settings, too high or too low would increase DH and HW.
Most important however would be your pool hashrate and the reject rate at the pool, if your miners are expected to run at 100th and you get anything above 97~th with say 1-2% rejection rate on the pool, ignore everything else you see on the miner GUI, if that isn't the case -- you got a problem, start by lowering the frequency.
