I have a Asrock B450m a/c with a ryzen 2600 cpu. Everything runs perfectly fine except ASRRGBLED software. I can't address using the actual icon in the software, just the AMD fan led. When I do change a value say I want all lights static red the front panel LED turns red and the in case fan lights turn green. the only values that I can use with the MB setting on my remote are blue, white or yellow. Anything else the colors opposite and it looks hideous. Also if i set the fans to static color via remote they'll flash their opposite value regardless of the software doing anything.

When I click addressable RGB header I can assign a value and I see the lights flicker each +1 or -1 click on the scale but no lights actually work.

This has been a nightmare and I'm about to RMA this pos and get something that works right.

Aside from straight up compatibility issues .. do you have the 5v addressable plug-in plugged into the 3 pin addressable header on mobo correctly?

some info that may or may not be helpful:

Yes the 3pin is connected from the MoBo ARGB_1 (can't plug it in anywhere else because of the 3pin blocked connector)to the 8 fan 2 led controller in the LED IN spot.

As of yesterday the addressable RGB in polychrome does nothing unless I change the value and all the lights flash for a blink of an eye and resume normal. If I use RGB FAN in the polychrome and push the MB button on my controller it was adjusting the levels opposite i.e Red would turn green (I checked and unchecked RGSwap) but the front LED panel on the tower responds to the correct color.

Fast forward a few hours of dealing with tech support from the people that built it giving me suggestions and I just started clicking the addressable value out of frustration. The front LED went black and I was forced to reboot and now the MB button wont even synch the lights.

Another honorable note if i set the colors via remote to a static setting they occasionally all flash green if I'm using red for a second then go back to normal. No performance loss or anything just buggy lights.

As of now the static values dont flash but the MB synch button doesn't do anything anymore since I uninstalled and re-installed polychrome after the forced reboot.
