Maximus Viii Extreme quad sli

[FuturisticMC]

I have a question about four-way SLI on the maximus viii extreme.
I know that there are four PCI express slots on the motherboard but I heard that only three of them can be used for video cards and the bottom one is only for soundcards or storage cards. What I want to know is can you bypass this, for example can you go into to the bios and change something for it to work or can you still hook up the four video cards in sli and it still work.

Unfortunately that won't be possible. The Maximus VIII Extreme is limited to 2 way SLI.

Unless things have changed from the maximus v extreme, the maximus viii extreme can do 4 way sli via the plx chip.

4 way sli would run x8 x16 x8 x8.

[FuturisticMC]

Really? Not even 3-way? Will there be another board that supports it?

[FuturisticMC]

It specifically says "Supports NVIDIA® Quad-GPU SLI™ Technology" in the specifications section of the motherboard though.

Yes the Extreme have quad GPU but the PCIe slot down is from chipset with4x lane and the on the top are 16,8,8 from processor

[FuturisticMC]

Ok, so it will work with quad sli, or only 3-way?

[DamianStr]

Quad will work

Quad sli means two dual gpu's, I don't think the maximus viii extreme is capable of 4 way sli, but is capable of amd 4 way crossfire. The maximus V and VI extreme can do 4 way sli due to a plx chip, it seems asus left the plx chip out this time around. For a 500 dollar board that can't do 4 way sli, you might as well just go the Rampage route.

Completely agree, this is almost too funny. Why would u release a so called extreme variant which had PLX chip in the previous versions always, and then cut one of the main important features and then price it at the same price of competing PLX equipped boards from other manufacturers who are now charging even $25-$30 less.
