The ROG Zenith Extreme is ASUS's flagship motherboard for first-generation AMD Ryzen Threadripper chips on the TR4 socket. It stands out with eight DDR4 slots, four PCIe x16 slots, three M.2 slots, a U.2 port and a bundled 10G LAN card, plus an EATX-class ATX layout built for multi-GPU workstations. It suits Threadripper owners who want maximum expansion and overclocking headroom rather than a compact build. Against later TRX40 boards it lacks PCIe 4.0 and newer USB, and its passive chipset cooling relies on case airflow. Reviewers rate its power delivery and slot count highly but flag the board's size, its early BIOS quirks and the fact that it is tied to a discontinued platform.
