4.7 PCI Express
The MITX-CORE-820 has one x16 5G PCI-Express slot which supports graphics cards up to 75 W
in power. The position of the PCI-Express slot follows the Mini-ITX Addendum Version 1.1 of the
microATX Motherboard Interface Specification Version 1.2.
The Cougar Point-mbl PCH has one x1 PCI-Express port (port 6) to the WG82579LM and one x1
PCI-Express port (port 3) to the WG82574L. Port 7 will be used for a PCI-Express Mini Card
connector for WiFi/WiMAX, port 8 is used for DMC card slot.

The MITX-CORE-820 provides two GbE ports. One port uses the Intel 6 Series PCH integrated
MAC and the Intel WG82579LM GbE PHY. The Intel WG82579LM is connected to PCH through
the 1x PCI-Express. The other Gbe port uses Intel WG82574L controller (MITX-CORE-820 only).
The design provides two RJ-45 connectors supporting 10/100/1000 Base T. LAN is powered by
suspend well to support AMT and wake-on-LAN while in S5. WG82579LM uses +V3.3 M and
WG82574L uses +V3.3 A.
