So I went out and bought two top-end Intel I350 dual nic cards, which connect to the mobo using PCI-e x4 connectivity. On my newer system the cards work fine. However, in my old system (an LGA775 socket, 975X chipset board) the system completely fails to detect that I've inserted the card. I wrote to MSI, and they inform me that the PCI-e x16/x8 slots are only capable of running gfx cards.
Which means I now have a requirement for a replacement mobo which will support the new intel network adapter. The problem is LGA775 is old-hat these days and the only boards I can find are micro-atx with only two RAM slots or DDR3 vs DDR2 - I have DDR2 memory, which would mean that I need to buy new RAM to support the maximum 8GB (I'm virtualising, remember) for full flexibility. Plus I'm out of cash now. Alternatively I could take a dremel to one of the PCI-e x1 slots and jury-rigg the x4 card into an x1 slot. Ho Hum. Regards, Daniel Llewellyn.
