The goal for Design Validation Testing or DVT, and the entire test flow is to detect defects in memory at different steps of testing. The most common defects found are structural defects related to DIMM assembly, component defects, and timing defects. Certain DIMMs are marginal at certain parameters, mainly because of signal integrity sensitivity, and such marginalities could lead to subtle application failures. Through this thorough testing, Viking Technology screens out bad components or DIMMs or marginal DIMMs making sure only the highest quality DIMMs are shipped to the customer.
