Gigabyte motherboard not recognising Dell PERC 6i card

[Redgie]

I have a nice new Gigabyte B360M-D3H motherboard, and have fitted to it an old Dell (LSI) PERC 6i RAID card. The card isn't recognised in the BIOS as a storage device and no prompts come up during boot (normally a length initialisation process would come up).

I have tried:
- Using the RAID card in another PC (it works fine)
- Using another PCI-E card in the Gigabyte board (a network card) (which also works fine)
- Updating the motherboard's firmware (no change)
- Disabling all the onboard SATA controller (no change)

This is leading me to think it may be an incompatibility between this specific card and this specific board?

Thanks in advance

Greetings,
I think you are correct.  The 6i is an x8 card.  I would only expect it to work in the top most slot (x16) if at all.  The other slots are x4 and x1

But I would expect an x8 card to work in a x16 slot?

I would as well, but for whatever reason it doesn't seem to like that card.  It may need an x8 slot...  I have never looked at the chipset.  An x4 card from another vendor will probably work.
