Summary: This article not only introduce Socket TR4 motherboard and its manufacturers, but also its
successor sTRX4 as well as the related socket SP3. Besides, a brief comparison is given among those
three kinds of sockets. Learn more CPU socket knowledge on MiniTool partition magic site.
What Is TR4 Motherboard?
TR4 motherboardreferstoa motherboardwith aTR4 CPU socket.
SocketTR4, also calledSP3r2,is an LGA (LandGrid Array) CPU socketdesignedbyCPUmanufacturer
AMD for itsfirstand secondgenerationof Zen-basedRyzenThreadripperdesktopprocessors.Those
processorswere launchedonAug.10th,2017 for the high-enddesktopsandworkstationplatforms.
Tip: When it comes to the third generation of Ryzen ThreadripperCPUs,theTR4 Socket was
succeeded by socket Strx4in 2019.

2. Alt=SocketTR4
AfterSocket1207 FX(short-lived),TR4SocketisAMD’s 2nd
LGA type of socketfor a consumer
product.It isphysicallyidentical to,yetelectricallyincompatible withAMDServerSocketSP3 (also
calledSP3r1) and itsinheritorStrx4. A TR4 socketwill preventthe usage of CPUsdesignedforSP3
socketswithanID pin.
SocketSP3 doesnotrequire a chipsetlike manyotherCPUsockets.Instead,itmakesuse of a
system-on-chip(SoC)mechanism.While TR4Socketandits successorStr4 socketneeda chipto
provide improvedfunctionality similartomostprocessorsockets.
AMD X399 chipsetwasdesignedforthe TR4socket.The chipsetsupports a total of 64 PCI Express
lanesforquad SLI/CrossFire configurations.PCI-Ex16slotsare usuallysetuponmost X399
motherboardswithsucharrangement:slot1(x16),slot2 (x8),slot3 (x16) and slot4 (x8).
Tip: SocketTR4 is madeby bothLotes and Foxconn.

About sTRX4 Socket
From the above content,youcan knowthat socketsTRX4 isalsoan LGA CPU socket,andit isknown
as SP3r3 (comparedtoSocketTR4 knownasSP3r2). The sTRX4 socketisdevelopedforAMD’sZen2-
basedCastle PeakRyzen Threadripperdesktopprocessors.ItisreleasedonNov.25th

Socket SP3 Overview
Still,socketSP3isan LGA CPU socketlaunchedbyAMD forits Zen- andZen2-basedEpyc server
processorsonJun.20th, 2017. It’sa system-on-a-chipsocketwhose processorincludesall features
