SandyBridge and SLI - Page 2

post #11 of 29
ud7, asus maximus IV/wS and other high end motheboard uses a nf200 chip to run the third pciE at 16x so you can do tri-sli but it create peformance loss, heat and latency. This is why the nvidia nf200 chip is not even enable until you run the third slot pci E tri-sli or use the 1 and 3 slot for sli. The mobo makers are aware of the nf200 problems but was the only way to get Tri working in p67 mobo and charge a premium for it. The p67 chip comes with 20X pciE bandwitch (without the nf200 chip) that is why you see 1 pci run a single card in 16X and 2 SLi in 8X, while having the third PCIE at 4x.

Short Answer:

Sandy Bridge supports suomething around 20 PCIe 2.0 lanes.

That's enough for 2x PCIe x8 slots, which is plenty for SLi/CF.

There are currently four boards which have a special NF200 chip and thus support an extra amount of lanes.

That's how they get 2x PCIe x16 or 3x PCIe x8.

Any high-performing hardware (within it's specific category based), whether it be LGA775, Lynnfield, Sandy-Bridge, or X58 is intended for the enthusiast, simply because there is always something cool for enthusiasts to do with it...overclock, fold, and etc.

Above, you can disagree without a personal attack.

To the OP, 8X8 vs 16x16 has been beaten to death. I does not matter, max 4% loss.

It's called an Ad-Hominem, and it's just in tune with the defensive nature of human kind. When you're in a place where no one can see your face and has no idea as to your actual worth, then treats you like crap.. it forces it out of you.

As to the discussion,

I do believe that instance, while positive, isn't as likely in every game.

But it's not a problem, since no one uses PCIe 2.0 x4.

I run SLI on my SB rig and I dont see any difference in frame rates from switching from a 16x x 16x board.

there no different between 8x sli and 16x sli. Only if you go 3 monitor with a resolution of 5k then you will see 16x tri-sli a small margin better fps. The link that you showed was 16x Sli vs 4X sli. which is not the topic here but this is proof thanx.
