Product is fine, but there is no manual in the box.
The seller poisoned the goods very quickly. Delivery from the Russian warehouse to Voronezh took 5 days. The product is fully consistent with the description. The board is used in conjunction with a Xeon 2680 v4 processor and regular UDIMM memory. It works stably and shows expected results in tests. I recommend thoroughly cleaning the plaque from the contact pads with an eraser on used processors before installing it into the socket. Thanks for this advice from the seller. The seller responds to messages very quickly. I recommend the product and the seller!
