Found this on the Nvidia Forum. I installed several of the Precision X1 versions and LED Sync does not work on any. I have two EVGA FTW3 2080Ti Ultra Hybrids and a generic Nvidia NVLink 3 Space Bridge. No matter what I tried, Led Sync or any control over the LEDs was buggy at best and does not work 90% of the time. I typically think EVGA is the best but I can also say the guys writing the code for Precision X1 are not accounting for the use of a non EVGA NVLink Bridge.
Here's what worked for me, again, I found this on the Nvidia Forum in a Google search, not taking credit just passing it on. I use MSI afterburner for overclocking so Precision is great but buggy. I still think it caused Bios issues on my cards.
You can Uninstall Precision X1 but NOT LED Sync and then navigate to C:\program files x86\EVGA\ledsync - create a shortcut, and change it that way. Ugly, but works for now.
I think the problem is that you must have an EVGA NVLink Bridge. Why? After editing the LedSync.cfg file and replacing the 0 with a 1 after [SLI1] at the bottom of the .cfg file I still have no control over the RGB settings of the NVLink bridge (again my NVLink Bridge is the Silver NVidia standard, which also is currently only available on Ebay the 3 Link bridge from any manufacturer is out of stock everywhere and the EVGA bridge is as rare as Hens Teeth), I do have control over the Cards, RGB is affected with color change or other flashing/pulsing/breathing options. I have a hunch the problem isn't the software necessarily, I think the problem is the hardware. If you have an
EVGA NVLink bridge and two EVGA GPU's and you run across this thread please verify that you have full control over the cards and the bridge RGB settings, by clicking on LED Sync.
