cpu? from the hpe specs it seems to be ivy bridge, to old for 918+ (loader 1.04b)
loader version and type?
i guess you will have to use 1.03b 3615 or 3617 (dsm 6.2) and keep in mind that it will not work as uefi, it needs csm/legacy mode
you can test with loader 1.02b (dsm 6.1),that one will work uefi and csm

that is a intel based card
hpe has the intern 4port adapter as "HP Ethernet 1Gb 4-port 366i Adapter" in the specs and from vendor id (8086) thats intel
