@Snow Tiger, you should post a link to where you got your 28core. Now that you tested the waters, let the floodgates open for others!
eBay from China . User zhpenn got his from taobao .
But there is a lot of risk in making a purchase like this :
The seller also sells ES / QS versions of this chip , so the buyer might wind up receiving something they didn't order and might not catch the mistake in time . So , at the very least , verify that the chip's serial number and other chip markings match via the method detailed in a previous post in this thread .
And while my seller appears honest , a dishonest seller could easily swap IHSs turning an ES / QS chip into a production chip , visually .
And , the seller categorically refused to send actual pictures of the item being purchased . A red flag .
And , if the processor doesn't work properly , sending the item back to China expedited and insured will be expensive from the American continent .
And Intel will not warranty this item , as it is a Tray version . So if it dies , you're out of luck . It's unlikely , but an expensive situation all the same . There's a reason why I burned my chip in for a week ...
And because this silicon is heavy and large , the buyer will have to carefully inspect the SMC and lands before installation . Its common to see damaged silicon offered for sale on eBay , being sold "as is " . So , use the posted pictures here of an undamaged chip when performing a visual inspection to verify all the tiny SMCs are still intact - it's easy for them to get knocked off . The lands ( the 3,647 little gold contacts on the reverse of the chip ) also can come loose , which would make the chip worthless until repaired .
And the chip needs to be cleaned properly , before installation . The installer needs to be immaculate about this .
