hi guys. This is worrying. My S11 is hashing at around 3T average but the advertised rate is 3.83T. Support hasn't been very helpful and I'm told to wait for the next firmware update.

Anyone knows why the S11 Sia miner is underperforming? I tried to update my firmware to the latest on their website below but it didn't help. Only brought down the temperature a little.
