I RMAed it ...
If I set static color = works flawlessly
If I set RGB color = hangs couple minutes
All USB power savings OFF, performance MAX with no power savings except shutting down monitors... I didn't pay for it 200$ not to not use RGB patterns. But no it's random, sometimes 1 minute, sometimes 5 sometimes 20min, one time (max) 60min and keyboard hanging, RGB frozen, need unplug USB and plug again. Doesn't matter, all people if you're having same problems, just change to static color.
