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?

Sorry to hear you couldn't get it working. I doubt the windows version has anything to do with it not working.

I just looked at the 3dmark scoreboard today and noticed my score got removed. Go figure. It was a legit score too.

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.

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.
