I just checked on one of my 2 units (both on latest firmware) and all the chips are x's and unit hasing at 0mh
second unit running fine.. did a reboot and will see if this happens again.. im dumb for not creating a copy of orig firmware that it was shipped with to try and flash it back to orig
edit: rebooted and now one chip is x, going to try and downclock from 537 to 531
edit2: still lowering freq as 531 was still getting lots of HW.. trying to find the sweet spot
I've had to drop too 500 frequency and or below to stabilize. Bottom line I think is....These things are NOT MADE to hash at 537. Yeah they can do it but it's redline territory. I'm just gonna run my units around 487-500 and roughly 17,000mhs. Whatever. Who cares if they make $3.85 a day or $4.00 or whatever the fuck it is. Bitmain might have thought if they overclocked these bastards to 537 they would hash fine until the warranty was up I guess they fucked that one up.
