Thread: PCI Slot (supports 2 Master)? What does it mean?

Yes they do make 2 slot risers. Only thing is is that if you have a standard 2 pci riser, it will act very bad if the cards are both highbandwith. The 2 cards will literally fight for bandwith.

You can buy a 2 slot PCI riser made for high bandwith items, but when I bought mine, it was difficult to setup.... could have just been me.... Logicsupply sells both types of riser.

And if you plug it in wrong, you let all the magic smoke out of your mobo.

Video and Sound are usually your main choices for PCI cards. Both would probably fall into that catagory. USB card would be another and it, too, would probably fall into high bandwidth catagory depending on how many devices it's controlling. Truth is, you probably just want to stay away from dual.

Edit: From looking at that other thread, they say you're fine, so you are probably fine running dual. Nice. At logic systems, they mention Via with their dual riser.
