what kind of firmware do you have?
if it is later firmware, you don't overclock by ssh, instead you go to the advanced tab in web gui, then choose one of the options :250, 237.5 or 225
save and apply

Can you please tell me how did you do that?
Because on Antminer's web
it say
Frequency
and
Voltage

Thanks!

you have newer firmware  leave volts at stock,  i think 725 for the volts is stock


  243 or 237 freq is the key

if you have a cool room and a good psu some make 250 freq some do 243  try both for an hour and look at your errors.

I have owned around 25-30 of them  most like 237 or 243 not 250 but I had a few that did 250

yeah  errors of 1 in 100 are okay.  1 in 500 is good

A very fast error check is this (it is an estimate and close to correct the real formula is longer but they are almost the same number)

 HW/DiffA

so for the one below :

433 errors in 30 hours

433/11,907,200 = 0.00003636    or 1 in 27,500  =  super good or great.

 also
 freq 231  mines at 460 gh
 freq 237  mines at 475 gh
 freq 243 mines at 490 gh

so if you are doing 485-495gh  and 1/500 errors you are good
