Mainboard
Mainboards for AMD AM5 and sTR5, from ASUS, Gigabyte, MSI and ASRock. Choose by socket first, then chipset, then the things you will actually use: memory slots, M.2 slots, rear ports and Wi-Fi. Workstation boards for Threadripper carry more PCIe lanes and memory channels than desktop boards. Each board's page lists the processors and memory it works with, so you can check fit before you order.
