Hi Sajin,
 
Spent most of the day trying to get this working and although I did manage to get 4 x Sli showing in Nvidia Control Panel when I ran time spy I was getting 6 FPS over 3 or 4 cards in SLI
I tested with two cards and got an ok score but not as good as with an NVLink bridge
Each timeI had a 3 or 4 cards in the machine then 3DMark started to have problems.
 
Tried every combination I could think of including 2 cards on the motherboard + 2 card on riser PCI-E cables (3 different cables and all had the same issues), 21 card in the machine with 3 x riser cables and each in every combination of slot possible.
 
Below are the specs of the machine that I tested on (I went for Threadripper as it supports 64 PCIE lanes)
 
Gigabyte X299 Gaming 7 Motherboard
16GB Corsair Dominator Memory 3200Mhz
Threadripper 1920x
500GB NVME Drive
2 x Palit 2080ti OC Pro
2 x Gigabyte 2080ti OC Windforce
1 x 1200W Platinum PSU (Corsair)
1 x 850W Corsair (for two of the GPUs wired to 24pin on a switch
ThermalTake P5 Case 
 
I installed Windows 1903 - not sure if I should have gone with an older version maybe?
 
 
 
 

I just looked at the 3dmark scoreboard today and noticed my score got removed. Go figure. It was a legit score too. 
 
https://www.3dmark.com/spy/7185899 Result is invalid. lol.

I do wish that 3D mark would post more information about removing scores, or at least the reason a score is removed so that folks can understand the reasons behind the removal of scores.

Since NVidia doesn’t officially support 4 way SLI, it’s not too surprising that the score was eventually removed. I still don’t understand how something that isn’t supported can be legit, especially when it requires changing drivers or the registry to get it to work.

This got me wondering, is it possible to get a super-computer to run and give a result for 3dmark? I doubt it'd be valid using odd hardware, but it'd be interesting to see if anyone has attempted it. (GPU score for a HGX-2 anyone?)
4 way RTX 2080 ti makes me want to push my questioning of what's possible out there.

Easy... time spy extreme officially supports 4-way sli, so when modding the driver to allow 4-way to work with 2080 ti's you can produce a valid score in 3dmark.  

Completely missed this reply, so... my bad on the 3 week delay lol.

I fully understand that the software officially supports 4-way sli. I don’t contest that at all and understand that it would produce a valid result.

The hardware does not officially support 4-way sli officially. The hardware only supports 2 GPUs. I would assume that is why the scores have been removed.

Honestly, if you have time, could you ask them directly? Since it is your results, I figure they may give you more details. They are very responsive to all of my past emails.

I asked to have the other 2080 ti 4-way config scores removed and they let them stand.

it's odd however also, as the CPU score is zero, even though other results have a CPU and total score listed, despite being invalid.
From what I'm seeing now, it has a CPU score and total Score of Zero, meaning maybe something else is wrong besides 4 way SLI of the RTX 2080 ti

The reason my score is like that is because I ended the tests by pressing the escape button after the 2nd graphics test was complete as I was only looking to get a gpu score, and not a total score. You can do this yourself.
