First of all, this is my PC environment:

i9 9900k\\2080ti gpu X2(419.67 creator ready version) \\32gb ram \\ Win10 1809

1.After my repeated tests, when my PC connects SLI with nvlink device, it will not be able to render ,

erro report:

2.OK,now I disable the nvlink by the nvida control panel. Then I can render the scene now, but the speed is slower than render by only one GPU .The pic below show it:

3.At last,I eject the nvlink hardware from My card,finally I can get the right result now.Like this:

SO.PLZ let me when U will fix this? Because I really need the nvlink to run other software and games~
