    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.

    Got the chip back FINALLY today. Checked the serial and it matched. Flipped it over and took an eraser to the black pads. The black removed but those pads were now silver. Slapped it in the most ghetto test setup you have ever seen. (My fiance's box and mine all have the cables routed specifically for our boards. Therefore I wasn't going to pull the hardware out of any of them to install the test board. Instead I set my test case next to my fiances box (hers is the easiest to rob power cables from) I connected one of her monitors, keyboard, and mouse along with stealing a stick or ram from it and connected a spare evo ssd.

    Powered it on and viola what was claimed it wouldn't do was just negated to a nice and pretty post screen. I set the basic bios settings that have to be set on a new computer to get it to bypass the F1 screen then plopped in a win 10 usb stick and rebooted to install windows and all updates. When the updates were done I downloaded and installed cpuz and the Intel Integrity test program to once again PROVE there isn't a single fucking thing wrong with this chip. Flying colors pass as I figured it would.

    Either he had bent or missing pins, didn't have the memory seated properly, Neglected to reset his bios on the chip change, or didn't actually have the newest bios installed for his board which was required to run a 3570K on an old Gigabyth 68 series 1155 board.

    Neither here nor there I'm out the shipping cost of getting him the chip in the first place. I'll be cancelling the sale to recoup my seller fees and then putting it back up for $10 more then I sold it for to make up for the lost shipping cost. I'm just damn glad the chip works considering what I tested and sold him was a working chip so if it didn't work anymore then he trashed it. Thankfully this wasn't the case though. My real guess is he was hoping for a delided golden 3570K and it just didn't perform as to what he wanted so he claimed it was doa and blamed the black pads on the bottom which for all I know he put on there himself with a pen or something.

    Black stuff on fhe pads.. hmm arching from weak connection? As in bent pins probably.

    Good for you! Glad it will all work out in the end.

    Another possible reason it wouldn't post for him. He had screwed pins and the chip wouldn't boot but as you said arching was going on while he was trying to get it to work. Hence the black soot or what ever on the pads. I sure didn't notice it before I sent it to him.

    With how uniform those black marks where, I feel they are intentional. They look placed there.

    LOL Yea well hopefully the next buyer has common sense and knows wtf they are doing. It's been a long long while since I had an issue with someone on ebay and computer parts. I didn't get to 808+ 100% FB and a power seller by selling shit that doesn't work. ;)

    I sell big end computer parts on ebay because people there are too stupid to know about hardware forums where "most" members are cheap asses. I would be lucky to get half the price here or any other hardware forum and especially over at hardwareswap. Those guys want everything and the kitchen sink for nothing.

    I was flipping Asus P8Z77-I Deluxe boards on Ebay for $270 for a while. Tell me I could get anything over $175 here. LOL
