Shame on them! But they're not experts and apparently someone ripped them off by swapping lids. I had to be sure, so I searched on Ebay for every Ryzen and than the 939's finally ID'd it as an FX series or AM3+. Shows how well they look at returns, very scary. Now if it was indeed a good say FX 8350-70, and you could prove it, well they sell for a good buck still! lmao! Just a joke, still not even close to what a 3700X costs. Unless I'm buying used, I always want one that comes in a sealed box.
