Lga 1151 with DDR 4 two memory slots USB 3.0. Excellent starters game board. Like new ATX Form motherboard nothing at all wrong with it, comes in the original packaging and drivers. Bought just recently off Amazon 3rd party and didn't realize it was the full ATX Form instead of a Micro Form. So returning to the 3rd party would have cost me a 25% fee plus shipping. So my loss and your gain. Priced to sell!
