sTRX4 platform for Threadripper workstations

The MSI PRO TRX40 PRO 10G motherboard uses the AMD TRX40 chipset and sTRX4 socket to support 3rd Gen AMD Ryzen Threadripper desktop processors in an ATX form factor. It provides eight 288-pin memory slots operating in quad-channel mode with a maximum capacity of 256 GB.

Multi-GPU and high-speed storage builds

Four PCIe 4.0 x16 slots configurable as x16/x8/x16/x8 suit multi-GPU compute or render nodes, while two M.2 Key M slots and eight SATA 6Gb/s ports with RAID 0/1/10 cover high-throughput storage arrays. Dual Intel i211AT 1 GbE ports and a USB 3.2 Gen 2x2 Type-C connector serve networking and fast external drives.

10 GbE connectivity for collaborative pipelines

The board includes a 10 GbE LAN controller alongside the dual 1 GbE ports, making it the decisive spec for studios that need direct high-speed links to shared storage or backup servers without add-in cards.
