PCIe x4 Slot
The conga-HPC/EVAL-Server provides three standard PCIe x4 slots:
•
PCIe lanes 12-15 on connector X8
•
PCIe lanes 56-59 on connector X13
•
PCIe lanes 60-63 on connector X14
With jumper JP14, you can permanently enable the clock request (PCIe_CLKREQ3#) for connectors X13 and X14. For connector X8, use jumper
JP13 to permanently enable its clock request (PCIe_CLKREQ0_HI#).

M.2 Key M Socket
The conga-HPC/EVAL-Server provides a standard M.2 key M, socket X6. The socket is routed to the module’s PCIe lanes 8-11 and it supports
2230, 2243, 2260, 2280 and 22110 M.2 card sizes. The red LED D4 lights when there is an activity on this socket.
With jumper JP12, you can permanently enable the socket’s clock request signal (PCIe_CLKREQ3#).
