I bought a Chelsio T520-SO-CR off ebay. What showed up doens't look anything like pictures I've seen. I cannot find any info when I put in what I think is the board revision number or the Part Number. (110-1188-50 Rev A or PT2170820) MAC:00:07:43:3E:AC:C8 I've included some pics and I was hopping this is the right sub to post in. I know the likely hood of this being a fake is small, more likely they sent me the wrong part but I wasn't sure how to title this post. Thank you to anyone who can tell me what I have because I've been searching all morning for a chelsio card that looks like this and can't seem to find it. I thought the T520-SO's had a bigger heat sink and from what I see in pics it looks a third larger than this card.
