SPD burning, testing, and inspection
After cutting, modules end up in black trays looking pretty much ready to go. But there's still much to do. Oh yes.

Modules go into an SPD (serial-presence detect) burning machine, which programs information about the module, its rated speed, latency timings, etc. Without SPD settings, customers or end-users would have to configure each new memory module manually.

With their SPDs configured, modules move on to the testing farm. There, real PCs put the memory through its paces to make sure it doesn't throw up errors or fail to work as advertised.

Not pictured: the high-temperature testing room, where modules are put through the wringer at temperatures of 55-60°C. The guide told us that Kingston tests a staggering 120,000 modules each day at this factory.

Factory workers also examine modules for cosmetic defects. According to our guide, only 0.4% of modules have such imperfections. By the end of this year, Kingston expects to have automatic inspection equipment in place to "assist" employees with this task.
