Hello everyone,

I recently bought an ASRock RX 6800 XT Phantom Gaming OC.

But while trying to change the color of the front led panel by using Polychrome SYNC,
The Led panel stopped moving (It was a rainbow wave at the begining).
So I tried to turn it off by using the little switch in front of the GPU but nothing happened.
Then I restarted my computer but the led didn't turn ON and nothing seems to be able to turn them ON again.

Polychrom don't work anymore and shows me the Error 0xFFFB (No ASRock device detected.)
I also used DDU to wipe my drivers and I reinstalled them using the AMD Adrenaline Software, but nothing.
Sometimes my desktop turns black.

I have contacted the support but still nothing.
What can I do to make my led work again ?
thank for your help.

Hi, I have the Rx 6800 phantom gaming version, but I think Rx 6800xt phantom gaming has an argb pin header that can be directly connected to the argb header of the motherboard, but keep in mind that your motherboard must support the argb, but it is better to research and Do this after making sure, if turning off or on the switch on the graphics card did not solve your problem

In the end, if it is possible to contact the support team again, it is better to consult them according to your conditions for this problem

Hey Alex, thanks for your replies.

Unfortunatly, the switch on the GPU doesn't do anythings.
I still don't have any respond for the ticket that I send to the support team.
I will search for the ARGB pin that you are referring to.

But as I said, the ARGB front panel worked just fine before I used the soft from ASRock.
Maybe you know how I can reset the LED drivers ?

Firstly, ensure you have the latest Polychrome SYNC version compatible with your hardware. Attempt a BIOS update for your motherboard and ensure all related drivers are up-to-date. Try a physical inspection of the GPU, ensuring the LED cables are securely connected. In the AMD Adrenaline Software, reset any GPU settings to default. If the issue persists, attempt a clean reinstall of Polychrome SYNC after removing any remnants of its previous installations. If these steps don't resolve the problem, it might be a hardware issue, and continuing to seek assistance from ASRock support is advised.

Hello again,

the fact is that the only available file for the LED BIOS is the same file that they put on the ASRock website in the support/faq section of the page related to the product.

If you have run this file before and received a failed update message, i suggest you use the method of connecting the GPU with the argb cable to the motherboard.

To update the BIOS LED, make sure that you follow the steps correctly, my graphic card got into trouble through this file, and its LED didn't turn on anymore.

Hello Alex,

Your link to the ASRock website with the FAQ solved my problem,
The steps were very easy to follow.

The software "work" i guess. As soon as the soft started, my front panel turned on.
I didn't try to use it because I was afraid to break it again.

But everything's good now. thank a lot for your dedicated help :D
