I don't remember the time frame but it was a Slot A cpu that I bought from some russian owned company in Irvine in the early 2000's that was doing exactly this practice. Since I was planning on overclocking it myself, and had taken steps to record as much about the transaction myself (because I knew this scam was going on), when reported to AMD, they had their lawyers contact me to provide an affidavit because they we're attempting to sue the shit out as many of these sellers as possible. They also replaced the cpu with the one I intended to purchase so at least the story ended nicely but what a pain in the ass it was.
