Just had another Z9 Mini that arrived today have a chip blow out (x000) when Oc'd to 668 seems that the late batch 2 machines dont just stop hashing when Oc'd too much they loose a chip
Wow man feel sorry for you. Can you get a replacement board?
thing is it works ar 500 freq fine ... just when i OC it it fails, Bitmain will want a screenshot showing the failure.. and i cant give them a overlocked screenshot ...emmmmmmm

If there is a way to set the freq of the boards individually say board 1 at 675 board 2 at 550 and board 3 at 675 ??... any ideas??
