Our take on the ASUS Alpha STR4 Extended ATX AMD Motherboard

The ASUS Alpha STR4 is an extended ATX workstation board for first-generation AMD Ryzen Threadripper chips on socket TR4. It stands out with eight DDR4 slots for up to 128 GB, four PCIe x16 slots with SLI and CrossFire support, three M.2 slots and onboard Wi-Fi with Bluetooth. It suits workstation and content-creation builds that need many cores, lots of memory and multiple GPUs. Against later TRX40 boards it is older: PCIe 3.0 only, no U.2, and just two 4-pin fan headers, so cooling planning matters.

Questions and answers

Which CPUs fit this board?
It uses socket TR4 and supports first-generation AMD Ryzen Threadripper processors. Later Threadripper generations use different sockets and will not fit.

There are three M.2 slots (2242 to 22110) and SATA III ports for 2.5-inch and 3.5-inch drives. RAID 0, 1 and 10 are supported.
Does it have Wi-Fi and Bluetooth?
Yes, both are built in, along with an RJ45 LAN port. You do not need a separate wireless card.
