Antminer Z9 Mini - OpenBenchWoodCube - ! Case and Firmware – News !
CASE changes:
Have again changed the placement of the hashboards and this also improved the cooling.
Complete “z9-Mini-Cube“ again rewired and made new grid for the boards.
I have also reinstalled the controlboard, now there is a more even exhaust air at the rear.
FIRMWARE changes:
A few days ago i have made a complete "factory reset" at my machine. Then I had to fix the controlboard. Now the miner is running the standardconfig. All values are now displayed correctly and all 4 boards are working.
A friend of mine has again built my own GUI. Here I have the opportunity to monitor the CHIP, PCB and KSOL.
CHIP view:
PCB view:
KSOL view:
At the moment my z9-mini is very stable at 4x618 mhz. However, I still have the problem with further overclocking, that the first card, sometimes without "error" (pcb ~ 48-50 degrees, chip ~ 65-70 degrees) turns off.
She stops mining for about half a minute, then she starts normally again and keeps counting. There is also no HW error which is normally marked with "XXXX".
Very funny especially because this is the "coldest" card. Maybe I get the problem still solved. Currently, the overclocking remains at 600-618 mhz.
I hope you like my setup? If someone can help me with the "first hashboard" error or has a tip, I would be very grateful for some advice.
Happy Mining to you ALL !!!

Amazing work! How exactly did you manage to enable the 4th chain? I can only get 3 boards working on my z9 mini :(
