The circuit board is so green.. and the heatspreader looks so plasticy and simple... I don't think that thing has ever worked... I would indeed recommend you to contact Amazon to get you a new CPU or refund.
So, I bought this Xeon E5 2650 v4 from Amazon (sold & shipped). The only SKU for it that turns up on Google has 2011-v3 socket type associated with it, which is the kind of server board I have for my application. Here's the issue, the processor that I got sent has the right etchings on it, but it's NOT 2011-v3 as can be seen in the attached picture. The sticker at the bottom of the cpu box says "LGA2011V4" on it. The question is, what sorcery is this? And what's LGA2011V4?
