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??
Did you come up with any solution yet?
I'm having similar issue. I haven't looked hard enough to see if one of the chip fails but when I over clocked my second batch to 668, it would give me decent hash rate between 14-16k for few hours but then the hash rate would drop to 9k. So I'm guessing it must be the chip failure. This happened multiple times and I started with 700. Now I have further reduced it to 650. Crossing my fingers. Interestingly to OC, I just had to pick the frequency from the drop down options.
My Second z9 from the second batch, I had to overclock differently because the option wasn't there and that has been more stable at 675 frequency than the one which had the drop down option to change the frequency!
