I have a new motherboard that only has PCI Express x16 gen2 slots. I have a newer NI PCI GPIB card will this card work in this slot? I have read in another topic that the newer cards are keyed for PCI express X but should the X have a number at the end such as 1,4,8 or 16
That can be a little bit confusing. The newer PCI boards are compatible with PCI-X slots, not PXI Express slots. It is unfortunate that the names are so similar. PCI-X refers to 64-bit PCI slots, which were mostly found on servers and Power Macs. They generally used 3.3 volt signal levels instead of the 5 volts used by our older hardware, which is why the keying was changed as you mentioned in your post.
As far as your current computer, it sounds like you will have to switch to a GPIB interface on a different bus, either PCI Express or USB.
