PCIe x4 Slot

The conga-MEVAL provides a standard PCIe x4 slot connector X74 (Slot 0). This slot, which is routed to the module's PCIe lanes 0–3, shares:
• PCIe lane 1 with connector X8 (Slot 1)
• PCIe lane 2 with connector X15 (mPCIe slot)
• PCIe lane 3 with connector X84 (Slot 2)
PCIe Slot 0 supports one PCIe lane (x1 link) by default. To support x4 link operation, set jumper X75 as described in the table below:
