Burn-in testing
Burn-in testing runs new hardware at sustained full load before deployment to catch early failures before a customer sees them.
Burn-in testing is the practice of running a newly built system at sustained, often maximum, load for a fixed period before it ships or goes into production. It targets infant mortality, the higher failure rate defective components show in their first hours of operation. The load forces marginal parts to fail on the bench instead of in the field.
Integrators commonly run burn-in for 24 to 72 hours, pairing CPU stress tools like Prime95 with memory testers like MemTest86 and GPU load generators like gpu-burn. They log temperatures, clock stability, and ECC error counts throughout the run. A multi GPU server might run 48 hours at full tensor load to confirm every card holds its rated clocks without thermal throttling or driver crashes.
When buying integrated systems, ask whether burn-in is standard practice and how long it runs. Systems that skip it push infant mortality failures onto the buyer's first weeks of use instead of the vendor's bench.
