Questions about this item

What does the TRX40 chipset cap in practice?

The TRX40 chipset caps maximum memory at 256GB of DDR4 and provides the platform interface for Socket sTRX4 processors.

What physical clearance does the ATX motherboard need?

The board follows the ATX form factor and requires a chassis with matching ATX mounting holes and an I/O shield cut-out.

How is the motherboard installed and which step is often missed?

Install the I/O shield first, mount the board on standoffs using all screw positions, then attach the 1× SATA cable and CMOS battery before powering on.
