A big takeawayfrom our AMD Ryzen Threadripper 1950X and 1950X review is the increase in CPU connected PCIe 3.0 lanes. A full 60 lanes are available to the PCIe slots and M.2 drives, while 4 lanes head off to the chipset where it's muxed for USB, SATA, low-level I/O, and other features. The increase in CPU PCIe lanes is set up to allowfor a lot more flexibilityconnecting devices usingPCIe bandwidth.
Three SafeSlots offer plenty of capacity for multiple graphics cards, and you still get a fourth slot linked to the CPU. Each of those has a dedicated connection, with no sharing between them, and the same is true for the PCIe pathways for storage. The primary M.2 slot shares a heatsink with the chipset to lower drive temperatures under load, and the secondary slot protrudes outward near the DIMM slots, where drives can be cooled by airflow from adjacent system and radiator fans. Factor in the U.2 port, and you’ve got a solid recipe for future SSD expansion or loading up from the start. The diagram shows the two hubs for everything to connect to: the CPU and the chipset. The CPU has 60 PCIe lanes, provided in 3 or 4 PCIe root complexes at x16 each (the diagram above suggests x16/x8/x16/x8). These will often go towards the main PCIe slots to support add-in cards like GPUs, or they could be partitioned off for RAID controllers or fast ethernet if required. In total, AMD has stated that the platform can support six GPUs maximum. The CPU also supports eight USB 3.1 (5 Gbps) Type-A ports, quad channel DDR4, and support for up to three PCIe 3.0 x4 storage drives for 3-way NVMe.AMD's marketing on the left is set out to explain that each product in the Threadripper and X399 line will be 'fully enabled' - none of the chips will be limited in PCIe lane counts or DRAM for the sake of segmentation. AMD is happy at this point to keep segmentation limited to cores, frequency, and L3 cache. Liquid adornments are complemented by comprehensive fan speed controls capable of managing a full system’s cooling through a single intuitive interface. Our FanXpert intelligence can now adjust each fan’s speed based on the hottest input from a group of configurable sensors, including the GPU diode on compatible graphics cards. This allows the cooling to react to a range of different workloads, like gaming binges that turn your graphics card into a space heater, and complex rendering that lights up all the cores on your CPU. All-new for this generation, the Zenith Extreme is the flagship of ROG’s AMD motherboard lineup. It comes with all of our latest features, including innovations available only on a select group of top-of-the-line models. Two RGB headers prime the X399-A to illuminate up to four meters of lighting at optimal brightness. The lighting on the board itself is discreet, with a gentle glow emanating from below the chipset heatsink. Even with the lights turned off, the interplay of angular lines and bare metal makes the Prime stand out.

It has the new BIOS which is pretty much similar to the previous one with few additional features. You can now switch between simple and advanced interface to tweak up the system per your expertise. We observed mouse lag while using the BIOS, but it was still usable. With so much bandwidth inside the platform, we had to give our X399 motherboards lots of ultra-fast connectivity to reach outside the box. For external devices, USB 3.1 Gen 2 ports provide 10Gbps links in all the flavors: Type-A, Type-C, and front panel. The Gigabit networking uses reliable Intel controllers, and that’s just the start. The ROG Zenith Extreme takes networking up a notch with not only a wired 10G Ethernet card, but also a wireless 802.11ad module. Although all our X399 motherboards have four PCIe x16 slots hooked up to the CPU, only the Zenith Extreme is designed for that many graphics cards. Its slots are spaced for double-wide coolers if you want to horde GPU power to leave your mark on benchmark leaderboards. On a more practical note, adding a fourth card can further accelerate compute-heavy workloads like 3D rendering and deep learning. To combat GPU sag, we include our ROG VGA Holder, which is strong enough to keep even the heaviest graphics cards horizontal.
AMD X399 Ultra Durable motherboard with Dual Intel GbE LAN, Triple M.2 with Thermal Guard, 120dB SNR ALC1220, Front & Rear USB 3.1 Type-C, RGB FUSION 2.0, Intel Dual Band 802.11ac WiFi+BT4.2, Base Plated & I/O Shield Armor When PCIe is the game, it becomes time to play with controllers and ports to see what fits. It all starts with the underlying diagram for Threadripper and X399:Bandwidth is a huge part of Threadripper’s appeal. The mother lode of PCI Express lanes stands ready for the multiple high-end graphics cards required for truly cutting-edge gaming and VR experiences. All of our X399 motherboards support three-way SLI and CrossFireX setups, and the Zenith Extreme can call upon a fourth card for record-setting benchmark attempts or an extra jolt of compute power. To protect your investment, SafeSlot reinforces the graphics slots against damage from increasingly heavy GPU coolers. Ready for cooling in any form, the diverse collection of liquid and fan headers lets you run everything from off-the-shelf AiOs to custom loops. With eight 4-pin headers in total, there’s enough capacity to cover an entire build.
