    Sold a working delidded 3570K to someone they are claiming their board won't post with this chip but will with another. They are claiming it has damage to several pads under the cpu.
    Below is the photo he sent.

    Looking around online so far I found only one place that talks about the contacts and which actually has a picture showing the same exact thing as the above. This article doesn't mention the one spot but does mention when the contacts are actually fried further down in the article. Which makes me think what is pictured above isn't actually damage to the cpu.

    That guy damaged it somehow and is claiming you sold him a defective chip. Here's another photo from google:

    Well I'm not so sure it's damaged after doing more searching online. I'm seeing different remarks on different forums. Some are saying chips with marks (or whatever they are) on the pads are from too many volts and they are fried. Others are saying it's from moisture, some say to use an eraser to remove the darker spots. Who knows lol. I was referring to photos of the same issue though not a pristine chip.

    Many that have chips with dark pads still have no problem with the chips working as they should either.

    I don't know if I should file with Ebay/Paypal against this guy or just tell him to send it back and I'll test it myself. I sure as hell don't want to tell him to take an eraser to it just in case it is still good and he didn't fry it which in turn would mean he is just having a hardware issue with his own stuff. That way I can take an eraser to it myself "gently" and see what happens. Sure wish I still had the board it was in so I could test it when it comes back.

    I'm going to be out the shipping to him and the purchase of a board I will have no use for once I do test the chip since no one is hitting me up in my area for my thread in the FS/T forum.

    Ahh, I gotcha. When I had my Z77 board and 3570K, I never noticed those marks on the pads on my chip. Though I had that sucker clocked @ 4.7Ghz with 1.32v, none of the pads ever had markings/burnt markings. I also delidded using the vise/wood method. The person I sold it to is still using it to this day at the same clock speed.

    I saw other pics showing burnt markings along with fried sockets. I know this is a dumb question, but did you take pics of the chip and underside before you sold it? Might make for a good case against the buyer.

    It's better not to sell electronics on ebay(assuming ebay). Too many of these threads pop up.
