Intel views memory's role in the server as crucial and began its memory validation program in 1999. Memory suppliers wishing to validate their
memory modules must submit them to Intel's validation lab to complete a suite of rigorous tests while undergoing changes in voltage and temperature.
Upon passing all tests, Intel will post the validated part number along with details about the module including the specific DRAM used.
