I have an S7 that tries to hash gets to 5 TH then gives red light starts beeping. Out of warranty. Please any ideas?

lower the freq by 1000 if

700 go to 600
650 go to 550

check temps
check fan speeds

Thanks for the quick response! 600 stops the beeping and red light but can only get 4 TH.. Tried 650 and 625 and no beeping but Red light flashing

From this point I'd reset it.

Reset and still only 4 TH..
