I dont even have the option to modify my lights in x1.  I have a 3080 xc3 ultra.  

yeah, on my evga 2070 x3 ultra, i had that option, Led at the top of X1. but when i installed the 3080 and ran x1, its gone now. All i see now is VGA1 and HWM.

Mine's actually not saving too :( Anyone had fix? Running on latest XOC. Mine is 3080 FTW ultra

Just chiming in to say I have the same issue, always rainbow after reboot on LEDs. XC3 Ultra 3080, on v1.1.4.0 Precision X1

Unless you uninstall Precision X1 and delete the folders it will save once but you can't change it again after that.

I've found that sometimes the setting change doesn't take effect until PX1 starts in Windows. Then after a few reboots, it does seem to eventually stay as set, at least on my 2080Ti FTW3.

I have the 3080 FTW3 Ultra. I not only have the problem of the main LED resetting on every boot, also happens during power state changes while gaming. Hell, today, I looked at it directly and watched it switch from temperature to rainbow with no other programs running other than Microsoft Edge.
 
EVGA. You guys are looking like flaming amateur's. What the hell are you guys doing? You look like idiots. 10 dollars says that you don't know how to fix this, let along have anyone competent enough on the payroll to actually address this as a company of your size should. Do you have any engineers that aren't your cousin Vinney? I hope this post makes someone's blog and they continue to flame you for just sucking at coding RGB. This is just goddamn embarrassing.
 
HEY EVGA!!!! Are you going to do something about this, or are you not smart enough to figure it out? All that goddamn money you guys are making and you can't get this right. Yeah, you know you suck!
 
BTW, they will see that I just purchased a Hybrid kit and just write me off knowing that I still gave them money. EVGA does not care about this, and doesn't give a damn if this looks bad because they are just being force fed money from us.
 
And if I get banned, then they also do not care about my passion!

same issue with my 2080ti.  literally have burned a few days on this now.  about to simply detach the led power from the gpu. The setting will persist through a restart, but sleep/wake and it insta goes blue and I have to open the software to get it to go back.  Well past annoying since I use a task to sleep/wake my pc every night/day. 

Hello did you go to settings and selected precision x start with Windows ? This save me,have no trouble save my led on 3070 ultra after desktop turn on

Yes this is happening to me too. I have my GPU lights set to red and white depending on the temperature. After some time of playing maybe like 30mins or so the RGB lights just change to rainbow. I am not sure why, I stopped trying to figure it out. I assume it is a EVGA software bug that will be updated in the future.
