Hello guys  I´v been using D3 for some time now with custom firmware i never had any problems i was OC it for 3 months but tempratures were ok all the time. but now one of my chains didn´t show up so i reseted and noticed i get around 80HW per sec on 1 chip which normaly had 60 ASICs but now it shows 54   , tryed to reflash firmware , reconent cables and now i get 55 asics : the thing is the hashing board is working fine had it running for 2 days with bilions of HW before the chain ddoesnt show  up , i just reboot it and its running again but with shitloads of HW it seems to be hardware problem with hashing boad  my D3 is not under warranty anymore so should i just let it run with those HWs waiting for the chip to burn ? or is there any way to fix it ?
