ASRock has just launched a micro-ATX variant of its flagship socket LGA1151 motherboard that is targeted at professional overclockers. It is the Z170M OC Formula, but unlike most Z170 motherboard it only has two DDR4 DIMM slots. This is because ASRock wanted to use the extra space for stronger electrical components. The board features a 14-phase VRM for the CPU and a 2-phase VRM for the memory. It draws power from a combination of 24-pin ATX and 8-pin EPS connectors.
ASRock is making use of a 10-layer PCB to minimize electrical interference. This is of course an overclocking motherboard so you have onboard clock fine-tuning buttons, voltage measurement points, DirectKey auto-overclocking controls, lots of diagnostic LEDs all over the board, and manual switching between two redundant firmware EEPROM chips. This board also features HyperBClk technology, which is an external clock generator used to give users finer control over the base-clock.
As far as expansion slots go you have two PCI-Express 3.0 x16 (electrical x8/x8 with both populated), and a third PCIe 3.0 x16 slot that’s electrical gen 3.0 x4, and wired to the PCH. Storage is made up of a 32 Gb/s M.2 slot, and eight SATA 6 Gb/s, from which four ports can make up two 16 Gb/s SATA-Express connectors. There are also two USB 3.1 ports (1x Type-A / 1x Type-C), as well as eight USB 3.0 ports. The board also features ASRock’s high-end Purity 3 Audio solution and an Intel-driven Gigabit Ethernet connection. No word yet on pricing.
