Socket TR4, short for Socket Threadripper 4,[citation needed] also known as Socket SP3r2, is a land grid array (LGA) CPU socket designed by AMD supporting its Zen-based Ryzen Threadripper desktop processors,[1][2] launched on August 10, 2017[3] for the high-end desktop and workstation platforms. Socket TR4 is AMD's second LGA socket for a consumer product after the short lived Socket 1207 FX.[4][5] It is physically identical to, but incompatible with, AMD's server Socket SP3.[3]

It uses the X399 chipset, and supports a total of 66 PCI Express lanes for quad SLI/CrossFire setups[6]. PCI express ×16 slots are usually set up on most X399 motherboards like this: slot 1—×16, slot 2—×8, slot 3—×16, slot 4—×8).[citation needed] Slots 2 and 4 usually share bandwidth with M.2 slots (if occupied).[citation needed] The PCI Express ×8 slots will change to x4 speeds if the M.2 slots are occupied.[citation needed] The ASRock micro Taichi is the only microATX TR4 motherboard currently[when?] available on the market.[citation needed]
