PCI Express 2.0 x16, x8/x8?

post #1 of 11
Thread Starter 
What does it mean by "PCIExpress 2.0 x 16 slots (single at x16 or dual at x8/x8 mode)"?

Do both of these motherboards support up to a maximum of dual-SLI and dual-Crossfire or does the P8P67 PRO support tri-SLI / tri-Fire? (it has an additional PCIe slot)

And on the P8P67 PRO board, it appears that the dark blue PCIe slot has a larger gap then the white and black PCIe slots… why is this?
Thanks

When you have 2 cards in sli it uses 8 lanes for each card but there is a minimal difference in performance so don't worry. Oh and the big 2 slot gap is for 2 reasons 1 so you can fit 3 slot cards in sli or you can put in a pci card in between the cards i would guess.

Oh OK.. so if I understand correctly you can't have 16 lanes for each card in SLI? It just isn't possible?

The Asus P8P67 Pro supports Tri-SLI / Tri-Crossfire flawlessly? Still unsure why that top most PCIe slot is placed a bit further up in relation to the other PCIe slots :/

Thanks!

They support normal CrossFire/SLI, but not Tri. Tri-SLI/CF is useless, anyway. I wouldn't recommend it. Dual is more than enough.

Yes, they do have a third PCI-E slot, but it's not true CF/SLI.

What is the third PCIe slot for? Is it the very bottom slot which is considered the non-SLI PCIe slot? The only thing I can think of is a PhysX card? Or is there anything else?

You could use it for a PCI-E SSD, tv tuner, a raid card, a sound card, addon card with extra SATA ports or USB 3.0 ports, etc...

The slot may be up further for more space between graphic cards, which helps with cooling.

And the bottom PCIe slot is not intended for crossfire or SLI, right? Or can you still run that using the bottom slot, but not in "true" SLI/Crossfire mode? What is true crossfire and how is it better? Do they make a SLI/crossfire bridge long enough to extend from the very bottom PCIe slot to the very top one? (Just wondering)

Still unsure why they all 3 of the PCIe slots are different colors?

Also, when going crossfire or SLI, do you need to purchase a bridge seperately? Or do most video cards which support this dual mode come shipped with that bridge in the box?
