If you are Crossfiring two of these cards, do both PCIE Ports need to be x16 or can you run it with one on x16 and one on x4?

I am pretty sure you can, but x4 will run slower than the x16 so it wouldn't be at its full speed for one of them.

I would have to say no. From the AMD website: "AMD CrossFire harnesses the power of two or more discrete graphics cards working in parallel to dramatically improve gaming performance." This board has only one PCIx16 slot so it should only be running one discreet card. Though I'm personally using the onboard video from an A series chip.

Yes. With the mobo you can actually use upto two pci-e cards like this in crossfire.

My system runs a x16. I guess looking up my possible candidates I didn't realize the obvious difference. I plugged the card in and it still works! However, I would advise looking for x16 still, because it sounds like that is not always the case.

Yes. You can run these in crossfire. No cable or extra software required. Two cards will show four cards total displayed in your OS.

You can do either. But this card requires both available power adapters so take note that power consumption will be high with this card and higher running both

No because this motherboard doesn't have a PCI bridge it has 4 PCI express. You have to find one that goes x16 to x1 pci . This one is just the old PCI to x1.

If you are trying to install 2 of these cards into the same PC, the answer is "no". I asked SYBA tech support this exact same question, and they told me 2 cards would not work in the same PC. Hope this helps.

considering the pci 3.0 is backward compatible with the 2.0 specification there should be no problem, however, I have not tried this so it is a theoretical answer. I assume you have two 16 slots and the first is populated with another card. Also as mentioned in order to provide the best throughput you will need 4 lanes. Most motherboards provide 8 for the second 16 slot put it is worth a double check before you invest in the card.

Yes it will work fine. As a single card solution you will have a minimal performance drop compared to PCIe 3.0, but this drop will be more noticeable in SLi setups (multi-card).

You should put it on the dual x16 mode slot. x4, x8, x16 refer to the physical size of cards, meaning that the corresponding PCIe are of corresponding size. You may fit one video card into the x4 mode slot, but the output will not be as complex.

Hi John, base on your PC specification it should be able to work. But using 2 cards on the single PC I have not try before. You might want to email Visiontek sale support to check with them.

yes, this card plugs into a pci-express x16 slot. the only problem you may run into is the physical size of the card, it may be a tight squeeze on your mobo.

You don't actually use a PCI port, just the bracket slot. That port, however, will be useless with the module in place.

I have mine installed in PCIe x4 slots on an Asus server bd running ESXi 5.1 They certainly work with VMware, no drivers needed. What slot did you install? I never heard of an x12 slot. What motherboard? They should be immediately recognized. Did you check the configuration/network adapters tab of the host?

There aren't any - its all handled over the pci-e lanes and software. Therefore, you don't need any crossfire cables or connectors when running 2+ cards.

If they are in fact 4+4 pcie connectors then two (2 x 8) in each card should be fine.if not you can get molex to pcie adaptors 4 +4 molex to one 8 pcie
