 AMD Processor Memory Guidelines

​Third Party Tested Memory

In addition to our own memory testing, AMD works with independent third parties to provide a broader range of tested memory solutions for our customers. Computer Memory Test Labs (CMTL), an independent testing company, is able to test RAM modules from different module suppliers. System builders should access the CMTL website at www.cmtlabs.com and view the recommended memory module list for the specific motherboard manufacturer and motherboard model.

Note: The CMTL website is provided for informational purposes only, and AMD recommends that a system builder conduct its own testing and validation to confirm that the memory modules are suitable for its systems.
