    Intel T7600 SL9SJ have pins?

    Its already confusing as it is....
    I was looking on ebay for a T7600(specifically SL9SD, micro-FCPGA). And I found a T7600 SL9SJ. According to seller, it has the same specs as the SL9SD, which they are correct but SL9SJ is a micro-FCBGA. However, they have pictures of the processor and it shows that it has pins and with marking as SL9SJ. They even state on their description that it has pins, and for socket M (479m).
    How can this be? Intel listed SL9SD as Pin Grid Array, and SL9SJ as Ball Grid Array, how did they come up with a T7600 SL9SJ on a micro-FCPGA?

    Does anyone have an idea?

    You talking about osstore1 ? lol, they definitely have the labelling wrong. I dunno how one can replace the balls with pins. Probably they are screwing around with CPUs....

    FCBGA is gonna be like this

    I would just stay away from it, and get a SL9SD for a few extra bucks....if necessary.

    Unfortunately, I have already sent payment before I was able to notice that I had overlooked the packaging type of both chip. SL9SD is micro-FCPGA, while SL9SJ is micro-FCBGA. Technically both chips are the same, that is why when you have CPU-Z check, it will report as Socket 479mPGA even though it is a mBGA. (I could be wrong, I am not sure if CPU-Z would be able to differentiate between the two packaging type).

    I just received the chip this morning. Upon close inspection, everything what they put on their description was correct, T7600 SL9SJ with PINS!!!

    From the looks of it, they manage to solder PINS onto the T7600 mBGA chips. That is what they did not indicate on their description, that these mBGA chips has been CONVERTED to mPGA.

    Some other people were able to order these chips from them earlier and was working great after installation. No doubt about it that these chips would work when installed. I am just a little bit concerned regarding their durability and reliability.

    Wow, I am surprised that one can solder pins on the back of a FCBGA chip.

    AFAIK, soldering pins that way is literally impossible, and it could be that the processor's labelling has been tampered. Just thoughts....but according to documentations, etc....conversion of that sort is impossible....

    You can stress test the CPU for a while using Orthos (Small-FFTs)

    You can reflow solder a pin header onto the BGA. If you look carefully, you can probably see the adapter on the CPU.

    My friend bought one of these converted cpu before. It looks like that they solder another thin board with pins on the cpu with BGA (acts like an adapter). So it's thicker by < 1 mm. maybe it doesn't work with some laptop?
    He used that on a mac mini, so the height restriction is not a big issue...

    Noterev and Chapmanenskog were right... They did solder a thin board on the mBGA to put pins on them. At first I have not noticed this, but upon close inspection, I came to realized that they did just that.

    I installed the processor and put some Arctic Silver 5 on them as well...
    So far so good... I had them do the orthos stress test for about 2 hours now while i do a bunch of stuff and also write this post. So far no errors yet.
