Will a PCI Express x1 TV tuner work on a PCI Express x16 slot ?

The Promise card has a PCIe 2.0 8X interface, and the motherboard has a single PCIe 2.0 16x slot.

My questions is: Even though the PCIe 2.0 16x slot on the motherboard is generally intended to be used for graphics, can I expect other types of PCIe 2.0 cards to function in that slot?

I am planning on using only the onboard video processor for display, and I need the RAID adapter in this server.

It will work. PCIe will use disable what ever lanes are not in use. The 16x slot isn't dedicated to graphics in anyway - it is the same as any other PCIe slot. It's just that the only PCIe cards most use are graphics cards.


Yes a PCIE 8x card will work in a PCIE 16x slot, the slots are entirely backwards compatible. Wikipedia backs this up:

A PCIe card will fit into a slot of its physical size or larger, but may not fit into a smaller PCIe slot. Some slots use open-ended sockets to permit physically longer cards and will negotiate the best available electrical connection.
