Hello everyone

I just seen Optimum Tech's vedio Reacting to your Epic ITX PC Builds!
At 11:58 he show up a FormD T1 build with Dual 1080ti run sli with water cooling

I found that Build he use a C_Payne Bifurcation Risers made one x16 to x8x8
And it needs Motherboard Bios support pcie bifurcation setting x16 to x8x8


Right now I'm using Asus ROG STRIX Z390-I GAMING motherboard

And I had found Asus website
[Motherboard] Compatibility of PCIE bifurcation between Hyper M.2 series Cards and Add-On Graphic Cards

[Motherboard] Compatibility of PCIE bifurcation between Hyper M.2 series Cards and Add-On Graphic Cards | Official Support | ASUS Global

www.asus.com

The list is for Asus HYPER M.2 X16 CARD and ROG STRIX Z390-I GAMING is on

Does it mean my Z390i motherboard can use the Bifurcation Riser to run VEGA 64 crossfire?

The User menu isn't said it can run pcie bifurcation
But at menu 3.6.7 said it can Enabled or Disabled Hyper M.2X16 setting to detect nubers of SSD on Hyper M.2 X16 CARD
No said it made x16 to x8x8

Had anyone try Asus motherboard run it ?
Or should I just change my motherboard to Gigabyte Z390I said it can set pcie bifurcation on thir website?

Rog boards usually don’t support bifurcation,
just use as rock or gigabyte

Typical ASUS - pay more, get less

Also, z390 was phantom gaming itx has a sli certification, so it’s a good choice for ya. It supports crossfire too.

I was running nvlink 2080tis in a formd T1 case.
The only board I know that works out of box is the asrock x570 itx - has built in sli certificate.
