Hey everyone,
I've been working with my Avalon 1166Pro 81th for a while now, and one of the hashboards is acting up. It's displaying this error code:
I took a closer look at the hashboard and noticed that a capacitor, marked as C481, is missing near the A3201FPV3 ASIC chip. I checked my other two hashboards that are functioning fine, and they also don't have that capacitor. From what I gather, it's close to a chip that keeps the rest from working.
I suspect it could be due to some soldering issues during the PCB assembly.
Could anyone let me know what the value of that capacitor should be?
Thanks!
If you talking about the ceramic capacitor it should work without that capacitor I think there is another reason why it gives you more hardware errors according to your logs.
If you have a multimeter try to check the resistance on that section where the ceramic is gone and maybe there are some shorted parts that cause some parts to fall off.
Can you tell me which hash board is it the first or the middle hashboard?
Just a bit confused about the logs because MH shows the first hashboard has many hardware errors and the PVT_T1 shows abnormal values which is the middle board.
There are many problems in the middle board, some chips have abnormal temperature and abnormal domain voltage, and this board has no hash rate. If you have an Avalon tester, recommended use the tester to test this middle board separately to find out the specific cause of the failure.
