    But when i have both cards plugged into my x99 deluxe motherboard with 5930 shows the one on the top slot @x16 and the 2nd card in slot 3 runs @x8 and even if i put the 2nd card in slot one it still runs @ x8 even if it is installed by it self can anyone give any idea's what would be causing this as even when both cards are in the system they seem to be working ok with no shutdowns or anything ...

    Are you checking this with GPU-Z or some other software?

    Press the ? on GPUz to start the render test, then check if the lanes stay at x8

    So it's only that one card that seems stuck @ x8 ?

    The other card in any slot operates fine @ x16 ?

    Have you tried flicking the BIOS switch on the x8 GPU ?

    Just as a test, power off, flick the switch, boot back up and check

    Try that card in another PC, if its still stuck @ x8, RMA

    EDIT - No BIOS update for that GPU ?

    8GB 290's? That's totally worth the extra 100 quid.

    Sapphire in UK has had an 8GB R9 290X for a very long time with a hefty price premium.
