Tested Memory

3rd party tested memory occurs as requested by the memory vendors and is tested at an independent memory house that is not a part of Intel - Computer Memory Test Labs (CMTL).

Vendor self tested memory
Intel supplies the memory vendors that participate in this program with a common memory test plan to use as a basic checkout of the memory stability. Memory listed here was either tested by the memory vendor or by Intel using this test plan. These part numbers may not be readily available throughout the product life cycle.

The table below lists parts which passed testing conducted using Intel's Self Test program for Intel® Desktop Board DG33BU.
