1Why testing matters before day one
A Bitcoin miner is a specialised computer, called an ASIC, packed with hundreds of chips on several boards. It travels by sea or air, gets loaded and unloaded several times, and then has to run flat out, 24 hours a day, for years. Most faults show up early: a loose cable, a board knocked in transit, a fan that will not spin.
Finding those faults on day one is far better than finding them on day thirty. Every hour a unit is offline is an hour it earns nothing.
| Burn-in | Running a new unit at full load for an extended period to expose early failures. |
| Nominal hashrate | The hashrate the maker lists for a model, for example 563 TH/s for the Antminer S23 Hyd. |
| Hashboard | A circuit board covered in mining chips. |
| Rejected share | A piece of work the pool did not accept, often due to delay or errors. |
2The five stages, step by step
| 1 |
1. Unboxing inspection Technicians check the box and the unit for shipping damage: dents, loose screws, bent fins, rattles. Serial numbers are matched to the order. Hydro models get their water fittings checked. |
| 2 |
2. Physical setup The unit is placed in its rack, connected to power, network and, for hydro models, the cooling loop. Cables are seated firmly. |
| 3 |
3. Burn-in test The Bitcoin miner runs at full load for an extended period, often several hours or more. Weak chips, faulty boards and poor connections tend to fail here rather than later. |
| 4 |
4. Spec checks Hashrate, power draw, temperatures, fan speeds and error logs are compared with what the maker lists. |
| 5 |
5. Pool connection and monitoring The unit is pointed at the right mining pool and wallet, accepted shares are confirmed, and it joins 24/7 monitoring. |
Hydro Bitcoin miners add a few extra checks. Before power-on, the cooling loop is filled and pressure-tested so there are no leaks at the fittings. During burn-in, technicians watch coolant temperature going in and coming out, because a weak flow shows up as hot chips long before anything breaks. Air-cooled units get the same attention on the air side: clear intakes, every fan spinning, and no hot exhaust being pulled back in.
3What the spec checks look for
| Nominal hashrate | 563 TH/s |
| Measured average during burn-in | 548 TH/s (illustrative) |
| Hashrate ratio: 548 / 563 | about 97.3% |
| Listed power | 5,349 W |
| Measured power | 5,420 W (illustrative) |
| Power gap: 5,420 / 5,349 - 1 | about +1.3% |
| 97.3% |
| 90% |
| 66.7% |
4Why uptime is the real test
Testing does not stop at go-live. Professional hosts typically watch every unit around the clock for drops in hashrate, temperature spikes and lost pool connections. Every hour saved matters, because a Bitcoin miner earns only while it hashes.
Good monitoring works on alerts, not on someone staring at a screen. If a unit's hashrate drops below a set level, a board goes quiet, or temperatures climb, the system flags it and a technician can restart, reseat or swap a part. The faster a fault is spotted, the fewer hours are lost, which is why the size of the on-site team and the quality of the alerting matter as much as the building itself.
| Estimated revenue: 563 TH/s x about 3.5 cents | about $19.71 per day |

| 30 days at 98% uptime | about $579 |
| 30 days at 95% uptime | about $562 |
| Difference | about $17.73 a month |
