ASUS ROG Zenith Extreme X399 Motherboard Pictured Some More
More pictures emerge of ASUS' flagship socket TR4 motherboard for AMD Ryzen Threadripper processors, the Republic of Gamers (ROG) Zenith Extreme X399. Halfway between the width of a standard ATX and an E-ATX motherboard, the Zenith Extreme doesn't appear as crowded around the CPU socket as some of the other socket TR4 motherboards showed off at AMD's Computex 2016 reveal, this June. The CPU is powered by a high-current 8-phase VRM, and to preempt VRM overheating issues as seen on Intel X299 platform motherboards, ASUS deployed an active VRM cooling solution. Heat drawn by the VRM heatsink is transported to a secondary heatsink under the rear I/O shroud by a heat-pipe, which is ventilated by a 40 mm fan, which vents hot air through the rear.
The TR4 socket is wired to eight DDR4 DIMM slots, supporting up to 128 GB of quad-channel DDR4 memory; and four PCI-Express 3.0 x16 slots. Interestingly, these slots are wired x16/x8/x16/x8, even though the Ryzen Threadripper processor features 64 PCI-Express lanes, according to AMD. Other expansion slots include an open-ended PCI-Express 3.0 x4, and an x1 slot. The board draws power from a combination of 24-pin ATX, two 8-pin EPS, and an optional 4-pin Molex input. Storage includes four 32 Gb/s M.2 slots (two under the detachable chipset heatsink cover, and the other through the included DIMM.2 accessory), a 32 Gb/s U.2 port, and six SATA 6 Gbps ports. The metallic chipset heatsink cover features thermal padding, so it can draw heat from at least one stacked M.2 SSD.
USB connectivity includes twelve USB 3.0 ports (eight on the rear panel, four by headers), and two USB 3.1 ports (of which one is type-C). Networking is care of a WLAN card with 2x2 MU-MIMO 802.11ac and Bluetooth 4.2, an add-on card with a 10 GbE interface, and a GbE connection driven by an Intel i211-AT controller. The latest generation SupremeFX onboard audio solution features a 120 dBA SNR CODEC made by Realtek, paired with two headphones amplifiers, ground-layer isolation, and audio-grade capacitors.
ASUS could launch the Republic of Gamers Zenith Extreme motherboard alongside AMD's market-launch of the Ryzen Threadripper processors, by 9th August, 2017.

Where do you see the two M.2 slots on the board? There's one, but that's it, even the spec on the back of the box says as much.
Not that its a problem :D
1x DIMM.2 slot with 2 M.2 Socket 3 with M key
1x M.2 Socket 3 with M key.
Why do AMD boards not have a digital debug LED?
