MITX-CORE-820 Installation and Use (6806800M10H) 73
4.20 TPM/Port 80 Interface
There is an Intel standard 2x10 100" header for TPM and Port 80 debug on the board. In some
cases, the PCI-Express card and the TPM module can exist together on the board. However, if
the height of the heat sink from the bottom of the PCI-Express 16x card is over the standard
specifications, it may have a mechanical conflict with the TPM module, which is plugged on to
the TPM header. This is not a defect on the motherboard.
