The LEDs function properly using the controller and sync as expected.

Are there any more steps I should take? I'd be very grateful for any advice or assistance in solving this issue. While the performance of my motherboard is otherwise perfect, its only this little issue that is keeping this from being a perfect build.

Thanks,
