Solution 1:

That's the official answer from OWS, now another answer if it is possible to force hp controller to up it to x2 width, that will require some more research. -)

I tried this again on a slightly different HP platform, the 2U HP ProLiant DL380p Gen8 versus the 1U DL360p Gen8. I received the proper results using this combination of hardware.

Current Gen8 host firmware now allows the PCIe links to negotiate at the proper speeds, so these devices ARE compatible with ProLiant DL380p Gen8 servers.

Speed 5GT/s, Width x2, ASPM L0s L1, Latency L0 <512ns, L1 <64us
