Why not try using slot 2/3/4 for your tri-sli configuration? Shouldn't that give you 0/16x/8x/8x?
Or heck with all that and just go quad 🙂
Moving the cards down would as far I I know, run 8x/8x/8x, as slot 2 is 8x... sharing 8x with slot 1 which is 16x/8x.
--- If slot 2 is actually 16x/8x... not just a secondary 8x port... AND the system will boot without a card in slot 1.. PLEASE LET ME KNOW... I will deal with the lack of pin header and annoying wiring because it will be worth it!(not only that but the distance will be greater between cards, northbridge and CPU)
Last time I checked, neither GTX570s, nor the Asus Rampage III Extreme supports Quad-SLI.
--- I am using 4 cards, 3x SLI GTX570s + GTX460 for PhysX... but the 8x slots are really bottlenecking the system badly, the 4th card kills the system, leaving me to believe, the 3rd 16x slot is really helping the entire array, and the proper setup would be that as the primary card.
The R3E doesn't support Quad-SLI regardless of whether the card supports it or not, due to the lack of bandwidth without an NF200 (adds 16x chip, contained in the ROG Xpander).
I'm return the Asus Rampage III extreme, if I cannot get an ROG Xpander for Quad-SLI soon.
Quad-SLI is supported with a ROG Xpander (not yet released).

Somewhere on this ROG site, I found Asus set world record with a Rampage III Exteme with an ROG Xpander (16x/16x/16x/16x daughter card which goes on top of the PCIe part of the board)

Based on slots specifications of
1 x16/x8_a(1)
2 x8_b(1)
3 x16/x8_a(2)
4 x8_b(2)...
That leads me to think that slot 2 only runs 8x, but if it will run 16x, I will just move the array down, I've thought about it but doubt it. Someone earlier posted Intel specs require certain arrangements being such with a 8x for port 2.
**Please be wrong**
If anyone has any information about an ROG Xpander, please let me know, if I don't find one to buy or a 100% certain reasonable release date, it's bye-bye R3E, hello NF200 or 2xNF200 EVGA/Asus/Something Else with True x16/x16/x16 or True x16/x16/x16/x16....
And I'm a die hard Asus customer. They're the only motherboards I've bought in the last 10 years (except for an EVGA 750i). I even have 3x Asus 3D vision monitors and know Asus means quality and performance.
**Rant** Asus just made a dumb move to release a 4 PCIe slot board without NF200 when they already have a 3 slot board.
Obviously anyone building only a Tri-SLI setup would buy the 3 slot board.
-- so Obviously anyone interest in the 4 slot board WANTS QUAD support. /**end rant**
