50 CMX32M cpuModule BDM-610000075 Rev B
When used for non-graphics applications, the x16 link should only be used as a x8, x4, or x1 link. Use of the full
x16 width is only for a graphics add-in card, with the integrated graphics disabled.
The signals on the x16 link can also be used for additional outputs from the Integrated Graphics Device. Contact
RTD tech support for more details.
PCIe Link Configuration
This cpuModule supports a total of eight PCIe x1 links. The chipset, however, only provides five PCIe x1 links.
Four of the links on CN1 and CN2 are connected directly to the chipset. The other four are connected through
a PCIe packet switch, and share the bandwidth of a single x1 link back to the chipset. The links that are connected
to the PCIe switch do not support wake from S3 (D3cold). Only wake from S1 is supported. Table 31 below shows
the configuration of the PCIe x1 links on CN1.
