Bought a 1080 back in february, but I just put it in my computer a couple days ago.
Anyways, I installed Precision XOC and it seems i've got quite a bit of issues.
As Followed: Cannot access Profiles, set them up or use them in any way.
                   LED sync is downloaded but it is greyed out (looked up solutions to this, tried one but it didn't work)
                   Sensor Light is Greyed out as well, not sure why this is.
                   I have it set to open with OS, but it never opens all the way. I get the launcher of it for about 5 seconds but it never opens.
                   The fan curve always goes back to auto. I try to hard apply it and after maybe 20 minutes it likes to go back to auto at 600rpm.
 
Anyways, if anyone has any solutions to the problem with the software I have, help would be great. I have redownloaded twice, once to the previous version and 
once back to the same version, to no avail. Also it may be possible that the sensors on the card do not work because I was playing a less demanding game and 
noticed my GPU , or at least what XOC was saying, was at 89C at one point in time. That was with the fans set to 650rpm when I checked the temp as well.

Like Cool GTX wants to know, it's almost always essential to say exactly what hardware and OS you're running if you want any kind of meaningful help..Different things apply (or not) to different stuff.

You can make a 'Signature' with all that info in it that can be auto-attached to your posts by going to the top of the forum page, then 'User Control Panel', then 'Signature and Comment' in the 'Edit Profile' tab..List your stuff in the 'My Comment' area, then checkmark 'always attach signature to post'.
 
What version of Precision XOC you're using would be helpful too, but I guess we can assume it's the latest (6.2.7 as of now)..And then there's the Standalone and Steam versions.
 
I'm sure we can get things straightened out for you if you haven't on your own yet.
