Great board, just worked out of the box with 8 gpu's and the most recent Win10 (6/2018) version. Nice layout, way better than the ASRock H110 and it's silly, way too close PCI slots.

Amazing motherboard, i currently have 19 connected gpus on risers. It took a little work and a bios update as originally i couldnt get past 12 gpus. Currently we have 3x 1500w power supplies connected and a mixture of gtx 1060 and rx 480s attached and for the past month we have had a few teething...

This board is quite minimalistic except in the one place that counts, PCIe slots, makes for a great cost effective choice (especially when on special) if that's what you're after and the slave power headers make life a little easier too.

up and running right away with 12 gtx 1060s installed, have had no issues. Not worth it at all at $300 micro center is price gouging at. They had an entire shelf of mining boards to sell you at double msrp but won't sell you more than 1 graphics card, also at gouging prices.
