I checked BKDG for both Family 10 and 11 
(http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/41256.pdf
 and 
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/31116.pdf,
 and didn't find the related info, Can you share more info like the URL and the 
section number?
