ECS unveiled two socket LGA1151 motherboards based on the Z170 Express chipset, under its L337 line of gamer-centric products - the ATX Z170-Claymore, and the micro-ATX Z170-Blade (pictured in that order). The two pictured below are pre-launch versions, the company didn't finalize their heatsink design or color-scheme. The Z170-Claymore features a 12-phase CPU VRM, four DDR4 DIMM slots, and five PCI-Express x16 slots. Of these, three are wired to the CPU (x16/NC/NC or x8/x8/NC or x8/x4/x4); and two are gen 2.0 x4, wired to the Z170 PCH. Storage connectivity includes six SATA 6 Gb/s, one SATA-Express 16 Gb/s, one M.2, two USB 3.1, six USB 3.0, Realtek-made gigabit Ethernet and HD audio, and 2-way SLI support. The Z170-Blade, on the other hand, is a micro-ATX board with a 9-phase CPU VRM, two PCI-Express 3.0 x16 slots (x16/NC or x8/x8), one PCIe 2.0 x1, six SATA 6 Gb/s ports, an M.2 slot; 6-channel HD audio, and gigabit Ethernet, making up the modern connectivity. Two USB 3.1 and six USB 3.0 ports make for the rest of it.
