What CPUs can you identify with this one picture?

So I just purchased this lot of CPUs on fleabay... if I am right about what some of them are, the price was absolutely amazing.... even though this was an "I accidentally on eBay" buy as I mis-typed my max bid a few minutes before the auction ended.

What CPUs can you identify from this picture of the underside of them?

I do not have a picture of the topside.

One hint is that they are supposedly all XEONs.

God, I'm glad I cant answer that lol.
I feel kinda sane.

well I recognized couple of Xeon Westmere, Bid dies Xeon sandy Bridge and Big dies Xeon Ivy Bridge..

Those E5 26x0 are easily recognizable, the X5xx0 are also very popular, so I see they may be mostly 6c/12T - 10c/20T xeons..

really really hard to know that way lol..

Ok, so the one 2011 that has the 3x3 arrangement that is further spaced apart is an E5 16xx or 26xx (Sandy) from what I can find.

The one with the closer spaced 3x3 arrangement seems to be a v2 (Ivy)

The 8x 2011 with the single row of large caps look like E5 1680v2 to me... only one I can find that has that specific configuration. (Ivy 8-core unlocked).
