AMD TRX40 chipset for third-generation Ryzen

This ATX motherboard uses the AMD TRX40 chipset and the sTRX4 socket to support third-generation AMD Ryzen desktop processors. Four PCIe 4.0 x16 slots run in x16/x8/x16/x8 configuration for multi-GPU or accelerator builds.

Suited to workstations needing high memory

The board accepts up to 256GB of dual-channel DDR4 at 2133, 2400, 2666 or 3200MHz. Two LAN controllers — Intel I211AT Gigabit and Aquantia AQC107 10-Gigabit — serve demanding network workflows. Buyers who require integrated Wi-Fi or a different socket should look elsewhere.

256GB maximum memory capacity defines the build

Eight DIMM slots support dual-channel DDR4 up to 256GB total, setting the hard limit for memory-heavy workloads such as simulation, rendering or large dataset processing. Exceeding this capacity is not possible on this platform.

Questions about this item

What case and CPU cooler clearance does the ATX-sized Creator TRX40 board require?

The board follows the standard ATX form factor, so it fits any case that accepts ATX motherboards and leaves room for the sTRX4 socket retention mechanism and your chosen cooler.

Which power connectors must be seated before first boot, and which one is most often missed?

Connect the 24-pin ATX supply and both 8-pin EPS cables to the socket; the second EPS connector is the step builders most frequently forget.

How often should the CMOS battery included in the box be swapped?

The supplied lithium cell typically lasts several years; replace it when the system loses date and time settings after being unplugged.
