Memory Module Testing
First the modules are tested and, at the same time, their SPD chips are programmed. SPD (Serial Presence Detect) chips hold all info about the memory module, like its speed and timings.
After the SPD is programmed, the modules are tested in another station to make sure that the SPD was correctly programmed.
After that the modules go to compatibility testing, which is a huge lab with hundreds of motherboards from several different manufacturers to be tested for compatibility with several different platforms.
After that the module is ready to be marketed, so the modules are labeled, packed and shipped to Kingmax’s costumers.
