That can't be right, manual says that when running tri SLI/CFX you're running 16x-8x-8x.
I had to look in the specifications tab for the R4E to find this...
4 x PCIe 3.0/2.0 x16 (x16 or dual x16 or x16/x8/x16 or x16/x8/x8/x8, red) *1
1 x PCIe 3.0/2.0 x16 (x8 mode, gray) *1
(*1-1 This motherboard is ready to support PCIe 3.0 SPEC. Functions will be available when using PCIe 3.0-compliant devices. Please refer to www.asus.com
for updated details.)
on the Gene overview tab is reads...
SLI/CrossFireX – with x16/x16 (Gen 3.0) speed on a compact platform
with this in the specifications tab... obviously designed for only two graphics cards.
2 x PCIe 3.0/2.0 x16 (dual x16, red)
1 x PCIe 3.0/2.0 x16 (x8 mode, red)
so I thought you you can get 2 x16 slots without a plx with the 40 lanes? being the imc and other things reside on the chip...Edited by Butter Chicken - 9/15/13 at 4:54pm
