Wow, that motherboard is whack. Both 3-way bridges aren't high bandwidth. 
Note: You'll get higher scores using a high bandwidth bridge. I would suggest using the 100-4w-0042-LR bridge for the 1,5,7 config as the bridge should run at 650 MHz vs the 400 MHz bridges your board ships with.
That is because an HB Bridge cannot support 3-Way SLI
HB bridges have several differences, one of those differences is they run at 650 MHz. All led sli bridges run at 650 MHz.

Yes Most of us Know this, But they still do not Support 3-Way or 4-Way SLI. I have 4 HB Bridges and one HB Bridge from NVIDIA. This makes no since "Wow, that motherboard is whack. Both 3-way bridges aren't high bandwidth. "

It makes perfect since. I looked up a review on the board and didn't like it, so I said it was whack, and both 3-way bridges aren't high bandwidth.

Then Please Post a Link to a 3-Way HB SLI Bridge so we call all buy one, or two.

I would consider 100-4w-0042-LR to be a hb bridge as it has a feature of a hb sli bridge. I already linked it too. 100-3W-0032-LR is a hb 3-way bride as it also runs at 650 MHz.

If that's the case, that is :censored: retarded.
The bridge you have pictured is not even on EVGA's product page...
Welcome to the brave new world of only 2-way SLI support.

That's what I thought Gunslinger, its the lanes that's limiting you as it seems there isn't proper support for a 3 lanes with at least 8x going to all of them.
Out of curiosity are you running a PCI-E NVMe? You didn't specify whether or not when I mentioned it the first time. I'm asking again because the board may be pulling 4 lanes from one of your slots to feed the SSD. If so I'd suggest using a regular SATA SSD plugged into one of the SATA headers to test it and see if the lane allocation you need 8x8x8 appears in the bios.
No NVMe in the house, just plain old SSD's.

My next step would then be to get in touch with ASRock and see if they have perhaps a beta bios for you that will give you the proper PCI-E lane allocation to enable 3 way SLI. Maybe ask one of the admins on the ASRock forums? https://www.google.com/ur...3zxG4HkU9rvE0vUrwAFwJP

I think Sajin may be on to something Gunslinger After looking up your board it does indeed have a very unconventional 3 way SLI bridge. Have you tried using the one I circled using different PCI-E slots?

One way I got extra lanes resources was to disable the M.2 Ports and the 2nd Network port. One other item but I have to go into the Bios to get the info. I got x8x8x16x8 on my X99 Rig.

Maybe go back to X99 or X79 where this was easier :P haha. Good old 40 lane xeons make life so much easier when you're trying to SLI cards.
In all seriousness, I hope you get this figured out!

games attached tomb raider rise of 4k and witcher 3 4k In order to get it to work you will need one of the LED bridges such as msi or evga I have had the evga pro v2 3 way bridge on titan xp's in 3 way sli and with great scaling you also have to change the settings in nvidia inspector like sanjun has posted head over to guru3d forums and ask for venturi he will tell you exactly everything needed to get it working. https://forums.guru3d.com/threads/functional-4-way-sli-pascal-titan-x.409468/
