*edit* After looking at the current Hall of Fame records, it's clear he figured it out.

ok plan talk it works open profiler and newest one does not work NVidia removed the fills that you need to unlock 3 and 4 way.
you have to have a v2 bridge to make it work.
1 thin you need Nvidia Profile Inspector 2.13 or older  or the fill's will not work. NVidia changed them.
2make sure you are in _GLOBAL_DRIVER_PTOFILE(Base Profile)
3 scroll down to #6 sli and you want to click on the 3rd fill thin in drop down pick 0x00000004 SLI_GPU_COUNT_FOUR
4 click next fill #4 and pick drop down 0x00000004 SLI_PREDEFINED_GPU_COUNT_FOUR
5 click next fill #5 and pick drop down 0x00000004 SLI_PREDEFINED_GPU_COUNT_DX!)_FOUR
6 next scroll down to unknown fills where you have unhidden the 2 fill you need to unlock 3 and 4 way sli
7 first fill you have to find is 0x10FD4C5F(7 Profiles) and click on it.      to the right a drop down pick fill 0x01F296C1(Catzilla. Unigine 4.0 demo. 3DMark. Unigine: Valley demo.3D.... and click it. next

9 go to top right and click on apply changes. thin close profiler and thin reopen if it took whin you scroll down to sli the 3 fill you set will show that . and thin scroll down to unknow and the 2 you just added will show up now.
10 under NVidia control panel manage 3d settings (global settings) make sure you  set cuda-gpus to all and power management mode to Prefer maximum performance
11 I have only had one program to not work , and to fix it you got to program Settings in the manage 3d settings and scroll down to that program and force global setting and thin it work grate .
this should get it up and running like a dream for you.

cool seeing it working for you. did not know wherte your link was . I have never gone any way yet but 4/waylol in every thing and doing it with titian x pascals sences they came out . its fun to watch 2 cards try to beat 4. but I did get 2 kingpins and evga hb brige so going to try2 if it does not outdo my 4 I will get 2 more . but going to try it

The problem was a bad card.  It works fine by itself, but will not SLI in any configuration with the other cards.  I have 4 cards and ran some 3x SLI this weekend and it worked perfectly.  Just need to get #4 replaced and then it will be time for some 4x SLI benching.
 
It was about 15*F here yesterday, so I set up out in the garage to keep the GPU's nice and cool.
 






 

 


 
 

Need to say a big and very special thanks to Sam Nelson for the Nvinspector tips and also to bcavnaugh for the HB bridges!  Thanks for your help guys!

So where did you get that custom vbios from? Mind sharing it? I'd like to completely disable my power limit too. 

Glad to see 3-way is possible
 
Got 3 Titans X (p) to play with

Guessing you can't share the vbios right? That sucks. Have fun showing off your special scores.
