Burn-In Process

Any time you use new computer components, you are subject to the risk of manufacturing defects, shipping damage, and many other possible sources of hardware failure. A “burn-in” process stresses the components in a system, so that if they are close to failure, we can make sure they break here – allowing us to fix or replace them before the computer gets to our customer. It is much like the way Boeing puts huge stresses on aircraft wings before flying the aircraft: if the wings have a defect, and are going to fail, they want that failure to happen before the aircraft leaves the plant. So, a burn-in test helps ensure that only hardware without defects leaves our facility.

What exactly do we do? The first test we run is very targeted, with a rigorous memory verification tool that makes sure the proper amount of system RAM is detected and that it functions without error for an extended period of time. This test also hits the CPU pretty hard, and depending on the amount of memory in the computer can last several hours. It is critical to make sure that the RAM is rock-solid before moving on, though, since misbehaving memory can cause a whole host of issues once the operating system is up and running.

Next, Windows is installed and all driver and OS updates are applied. Afterward, we run several benchmarks to collect performance data which we use to make sure the workstation is performing as expected for its particular specifications. Toward the end of that process we use a combination of utilities at the same time, with the specific intention of pushing the hardware to its limits – putting the CPU, RAM, and GPU(s) under heavy load for several minutes to ensure stable operation, before considering the PC ready for quality control. A similar system-wide stress test is run again as part of QC, where we can also monitor temperatures to ensure adequate cooling and power draw from the wall to verify that the included power supply will be able to run the computer safely.
