Micron Server Test

View recorded test results

Two motherboards are used to perform the qualification tests; the minimum load is run in a system equipped with a single CPU while the maximum load is run in a system equipped with dual processors. Both systems use the latest BIOS revision.

  • Tests performed use both the minimum and maximum memory configurations supported by the motherboard.
  • The testing of each motherboard uses 8 hours of power cycling in both a Windows and DOS operating system.
  • Verification of memory configuration, size, and type ensures that the system has detected the memory properly.
  • The testing of each motherboard uses one complete loop using comprehensive memory diagnostics at ambient temperature and nominal voltage.

The testing of each motherboard uses comprehensive memory diagnostics at the following temperature and voltage conditions:

1.

High Temperature
Low Voltage

Full qualification testing uses the fastest CPU supported by the motherboard as well as the latest BIOS revision.

  • Tests performed use both the minimum and maximum memory configurations supported by the motherboard.
  • The measurement of signal quality may occur on critical signals to ensure the memory module meets data sheet specifications.
  • The duration of the memory diagnostic testing is 12 hours for each corner. Total test time per board is 48 hours.
  • Verification of memory configuration, size, and type ensures the system has detected the memory properly.

Basic Qualification Test

View recorded test results

Initial evaluation consists of multiple boot-up testing into two different operating systems, as well as a minimum of 4 hours of comprehensive memory diagnostic testing. The qualification test uses the fastest CPU supported by the motherboard as well as the latest BIOS revision.

  • Tests performed use both the minimum and maximum memory configurations supported by the motherboard.
  • The testing of each motherboard for one complete loop uses comprehensive memory diagnostics at ambient temperature and nominal voltage conditions.
  • The testing of each motherboard uses typical and graphics-intensive applications in at least one O/S environment for a minimum of 24 hours to ensure system compatibility with memory.
  • Verification of memory configuration, size, and type ensures the system has detected the memory properly.

Custom Qualification Test

Micron's test conditions, used to qualify Micron memory products, meet or exceed Intel's Full and Basic Functional Test Procedures as defined at Intel's "Desktop Board Component Functional Testing Levels" Web page, http://developer.intel.com/design/motherbd/genqual.htm.
