What Is TR4 Motherboard?

TR4 motherboard refers to a motherboard with a TR4 CPU socket.

Socket TR4, also called SP3r2, is an LGA (Land Grid Array) CPU socket designed by CPU manufacturer AMD for its first and second generation of Zen-based Ryzen Threadripper desktop processors. Those processors were launched on Aug. 10th, 2017 for the high-end desktops and workstation platforms.

Tip: When it comes to the third generation of Ryzen Threadripper CPUs, the TR4 Socket was succeeded by socket Strx4 in 2019.

Socket TR4

After Socket 1207 FX (short-lived), TR4 Socket is AMD’s 2nd LGA type of socket for a consumer product. It is physically identical to, yet electrically incompatible with AMD Server Socket SP3 (also called SP3r1) and its inheritor Strx4. A TR4 socket will prevent the usage of CPUs designed for SP3 sockets with an ID pin.

Socket SP3 does not require a chipset like many other CPU sockets. Instead, it makes use of a system-on-chip (SoC) mechanism. While TR4 Socket and its successor Str4 socket need a chip to provide improved functionality similar to most processor sockets.

AMD X399 chipset was designed for the TR4 socket. The chipset supports a total of 64 PCI Express lanes for quad SLI/CrossFire configurations. PCI-E x16 slots are usually set up on most X399 motherboards with such arrangement: slot 1 (x16), slot 2 (x8), slot 3 (x16) and slot 4 (x8).

Tip: Socket TR4 is made by both Lotes and Foxconn.

About sTRX4 Socket

From the above content, you can know that socket sTRX4 is also an LGA CPU socket, and it is known as SP3r3 (compared to Socket TR4 known as SP3r2). The sTRX4 socket is developed for AMD’s Zen 2-based Castle Peak Ryzen Threadripper desktop processors. It is released on Nov. 25th, 2019 for the high-end desktops and workstations.

Socket Strx4 is physically identical to, however electrically incompatible with its predecessor TR4 Socket and server socket SP3. Still requiring a chipset unlike SP3, sTRX4 is compatible with the TRX40 chipset that offers total 88 PCI-e 4.0 lanes, 22 more lanes than TR4 Socket.

sTRX4 socket no longer features a built-in High Definition Audio controller like other new sockets. This feature appears in every new platform since 2004 and serves as a replacement for AC’97. Instead, sTRX4 motherboard manufacturers embed separate USB audio controller on the mainboard to provide audio functionality like Realtek’s ALC4050H controller + ALC1220 codec.

Tip: AMD promised to support the sTRX4 socket for the long-term.

Socket SP3 Overview

Still, socket SP3 is an LGA CPU socket launched by AMD for its Zen- and Zen 2-based Epyc server processors on Jun. 20th, 2017. It’s a system-on-a-chip socket whose processor includes all features needed to make the system function fully like PCIe, SATA controller, memory, and so on, instead of requiring a specialized chipset.
