Received this card and pleased with performance but having RGB problems. When I boot up my PC the RGB is fine, I use the rainbow setting in the Sapphire TriXX software which is the default. However, after a random amount of time e.g 3hrs, 6hrs, 24 hrs, the RGB will turn red and flicker every 15 seconds or so. I can then change it to any other RGB setting but none of them look as nice as the rainbow wave in my opinion. Just wondering what the hecks going on really, and would appreciate some help!
