This support-focused topic in CPU/GPU Bitcoin Mining Hardware is for hardware troubleshooting. Good replies should cover overheating, fan problems, PSU instability, board issues, thermal throttling, and how to separate a real fault from a temporary condition.
My experience has been that many mining problems are not one big failure but several small issues at once. A setup can look almost correct while still underperforming because of heat, weak airflow, bad assumptions about variance, or poor monitoring. Threads like this are helpful when people explain not only the fix, but how they reached the fix and what signals pointed them in the right direction.
I agree with the general advice here, but I would also check the wallet address, worker naming, and temperature at the same time. A lot of people focus only on the connection and miss something obvious.
I had a similar situation on a smaller setup and the lesson for me was not to assume profitability or stability from one short test window. Watching behavior over a longer period gave me a more realistic picture.
Thanks for posting this. I was trying to figure out the same thing today.
This is exactly the kind of question many new miners search for before they commit money or hardware.
I think the most helpful answers here are the ones that explain what to check first, not just the final fix.
A practical comparison with real setup details would make this thread much more useful for future readers.
It helps a lot when people include what symptoms they saw, what they tested, and what actually changed the result.
This is a strong SEO-style topic because it matches the real questions miners keep asking again and again.
