But how does this effect performance?
With ASICS we are still in the age of performance over power savings.
This is with
zero impact to performance. Hashing at 760-770GHz, clocks all at 1000MHz, errors at same level as before tune, just less heat and less power.
Actually for me it's "improved" my hashing performance as I had one PSU kicking off on hot days and now the PSU also runs cooler.
