I bought 1070 sc few days ago,and I can not control 1070sc'led with EVGA Precision XOC(V6.0.8)(also in 6.0.7),the "led"is greyed out.(please see picture below)
how to control the led?

Welcome to the forums..LED Visualizer is included in most recent NVIDIA Driver packages up to about 373.06 and in GeForce Experience..The NvLedVisualizer.exe is tucked away in (for example) the C:\NVIDIA\DisplayDriver\373.06\Win10_64\International\LEDVisualizer folder..You can try it from there and see if/how it works for you..If it works it works, if it don't it don't.
 
You can snag the LED Visualizer from an older driver package since it's not included in new driver packages.
 
If your card supports any LED Visualizer functions, even with limited functionality, you should be good to go for what it offers..If not, it don't.
 
You can check in your current driver package (typically saved in C:\NVIDIA) unless it's been deleted somehow and see if it's there and if not or try the stand-alone one linked to above by Sajin or snag it out of another driver package and then you can delete the driver package if you want to..After you extract a driver package you can copy the LEDVisualizer folder from the driver package to wherever you want and make an NvLedVisualizer.exe shortcut to wherever want and see how all that works out..Precision XOC is still a work in progress, it seems..Just sayin'.

You can't change the color on the 1070 sc. You should only be able to turn led on/off. Have you tried reinstalling the latest version of precision xoc? If reinstalling the latest version of precision xoc doesn't help get the led tab working again you can use the led visualizer from nvidia to turn the led on/off... http://international.download.nvidia.com/GFE/LEDViz/1.0.0.0/LEDVisualizer_v1.0.0.0.exe 

Led visualizer is already in the drivers isn't it? C:/nvidia/*latest driver number or a previous driver" then led visualizer?

Nope.

Nope.

Why did they remove that? Why is Nvidia taking everything useful that they have out of the users hands?

I still have the same one linked that has been on my desktop for over a year. I still use it for the sli bridge occasionally.. Nvidia won't take that away lol.

Looks like it's suppose to be added back at some point. Looks like you'll also need to install GFE to get it... https://www.reddit.com/r/...geforce_experience_30/

Yes..Try it if you want to and see if it works for you..Seems that LEDVisualizer can be run from within the driver package download (after extraction to C:\NVIDIA\*) or as a stand-alone application from the LEDVisualizer folder in driver version 363.06 and NVIDIA driver packages older than v363.06 in other packages in relatively recent history..The program opens for me, but error "Supported NVIDIA card not Found" occurs, of course..The driver or Visualizer installation should not be necessary, just run the NvLedVisualizer.exe from the driver package..Newer drivers require GeForce Experience 3.0 and a login from other BS for that feature to run LEDVisualizer..Any feedback on that?..Just going from what I've 'heard' from others here and there?
