All I can say is - if Quad-CF works, I don't see why Quad-SLi wouldn't. Why would nVidia limit you to three cards when AMD lets you buy four?
Because that's the Nvidia way. You didn't know? Manufacturers have to pay Nvidia fees to get to use SLI. Nvidia wants another NF200 on there for Quad-SLI like the ROG Expander. It's like trying to Quad-SLI 570s: drivers just won't let you even if you tried.

But it doesn't make sense for nVidia to do something that limits its own profits.

Back in 2007, they invented Triple-SLi but only allowed it to be used with their expensive G80 cards.

Right now, not having Quad-SLi available AT ALL is ridiculous.

If they were only allowing Quad-SLi on GTX 580 cards, I could understand. But no Quad-SLi of ANY kind of P67? I doubt it.

You can still do it on X58 or use 2 590s. X79 SB-E will probably have dual NF200 chips on some mobos. I still think, unless you can find any evidence of 4-way Quad-SLI working on those mobos, you shouldn't list it as such, going against what the manufacturers describe it capable of.

I'm torn. It's inconclusive.

Nothing points to it being possible, but there are not threads complaining that it isn't.

I'm just going to go with the manufacturers are not being specific on their specifications and assume that four PCIe slots can handle Quad SLi.

lol, ok We think the opposite. I'm sure it could actually "handle" it, Nvidia probably just wants to get more money out of you to let you do it though. I think people aren't complaining about it because the product description already told them they couldn't do it when they bought it.

No but see, that doesn't make sense.

Why would nVidia be against the Maximus IV Extreme, one of the two best P67 boards, supporting Quad-SLi.

That means that there is no P67 board that supports Quad-SLi.

And that is something so weird, I am sure there was at least one 2600k owner who decided on four GTX 580s, not even thinking that the BEST board out there couldn't handle it.

And another thing - if nVidia wants more money for Quad-SLi.. how are we supposed to give it?

They have to charge ASUS the money, forcing ASUS to hike up prices, which would again, make perfect sense for their top-end board, for which they can charge anything they want.

All I can say is, I wish I had another GTX 480 so I could try Quad-SLi on it.

Any donators?

Not even the R3E supported it until the ROG Expander addon card came out. P67 probably doesn't have enough lanes for Nvidia to be satisfied. SB-E should have a mobo supporting 4-way.

You're right they'd make the extra money off Asus. Hopefully you find someone who's tried 4-way SLI to find out. That, or just pick up a 480 from a local store and return it after testing.

Hmm. So, you're saying that only very special, very specific boards, like the eVGA Classified are "permitted" to support Quad-SLi?

So what happens if you have one? You can just Quad-SLi?

How does the motherboard tell the drivers that it's okay? That seems like something very easily hacked.

You know, it's weird. I buy and bring back photography equipment costing thousands all the time.. but for some reason a 300$ graphics card seems novel to me

That seems to be how Nvidia plays it. Just like the not allowing SLI at all on non-certified boards like the x38 x48 P45 or not allowing 4-way 570s is limited by the drivers. They haven't hacked the P67 bios key yet so I don't know if or when there will be a patch for it. You can't 4-way on the M4E unless you have single slot GPUs anyways either.

Those chipsets were in competition with nVidia's own chipsets, at the time. That's why they didn't support SLi.

I think I'm going to solve this by redefining what I consider "Quad-SLi".

If the patch is created, then any motherboard with four PCIe slots will be "Quad-SLi compatible."

So, I think I will refer to it as simply "having four PCIe slots with at least 4 lanes each."

P.S. Wow! I had no idea you do SLi on P35 and P45! One of my 8800 GTS 512s has been in the closet for months because I was sure I could only use one. Thanks, man.
