I wanted to start a useful buying and setup thread for CPU/GPU Bitcoin Mining Hardware. What should miners check before buying used or new hardware, and what are the most common mistakes with efficiency, heat, power, and reliability?
What helped me most was writing down the exact symptoms before changing anything. Once I compared the dashboard, local logs, and power behavior together, the real cause became much easier to spot.
For anyone still troubleshooting this, the most useful sequence I found was: confirm the wallet and worker format first, then verify the stratum target, then check miner logs, then look at temperature and uptime, and only after that start changing firmware or network settings. Doing it in a clean order saved me a lot of time because I stopped guessing and started isolating the real problem.

Thanks for posting this. I was trying to figure out the same thing today.
I appreciate topics like this because they help newer miners avoid expensive errors and give experienced users a place to compare methods.
This is a useful topic because it gives miners the kind of practical detail that is often missing from generic advice.
I think discussions like this are strongest when people share exact setup details, what they tested, and what changed the result.
It also helps to separate theory from real-world miner experience, because many problems only show up under actual load and uptime conditions.
Threads like this can become excellent references when members explain the mistake, the symptoms, and the fix in a structured way.
