What is bifurcation ? I read one answer on quora but still dont get it.

Splitting up pci-e lanes? For what? To run 10 gpu's for mining on one pci-e port?

Also, to anyone unaware, I hope these links will help:

Using a quality riser card or PCIe cable to bifurcate a PCIe slot will not impact GPU performance:

Also, dividing a single 16x down to two 8x lanes has zero impact as well (even when comparing PCIe 3.0 to PCIe 2.0):

Linus also has a good video for PCI-E scaling.

SLI finally working ?

I've been working on a custom case for two bifurcated GPU for quite some time. Hope to achieve something around September.
Minimum I can achieve with liquid cooling (2U height) :
