The ASRock OC Formula's Layout has been very well thought. Once more practical are the angled SATA connectors as well as the power- and reset-buttons. ASRock even equipped this board with two M.2 slots, where one is wired through two Gen2 lanes and the other through four Gen3 lanes. There is also a debug display, which is always helpful if there are issues occuring with the motherboard itself or one of the installed components. Even the placement of the PCI-Express x16 is well chosen. There is a total of four of these slots and between two slots there is always an empty slot apart from the center. Here you find a full size Gen2 slot. We think this is a good number of PCI Express x16 slots for an overclocking/gaming motherboard altough most gamers will never use four graphics cards in their build. But still it leaves you with plenty of options if you want to plug in other expansion cards. Overclockers will also like the voltage readouts as well as conformal coating layer, which basically makes this board waterproof. In our opinion this board offers a very good feature mix.
